Disclosed is a thread measuring apparatus, which controls a back light source (102) so that a color difference between a thread (90) and an illumination may be at or higher than a predetermined value. With the illumination color of the back light source (102) being optimized, a digital image of the thread (90) is taken by a camera (6), and a two-dimensional Fourier-transformed image is formed along the width direction and the longitudinal direction of the thread. A low-frequency component corresponding to the thread body is extracted from the two-dimensional Fourier-transformed image, and is subjected to a two-dimensional reverse Fourier-transformation thereby reproducing the image of the thread body. Thus, it is possible to determine the thread diameter precisely and the color components of the thread.

DRESSING SIMULATION DEVICE, SIMULATION PROGRAM AND METHOD FOR SIMULATION
Multiple mass points are generated on a designed virtual garment and stable conditions of the multiple mass points are simulated by elastic force between the mass points and force exerted between a human body model and the mass point. A result of the simulation is displayed on a display device and, when the design is changed, a distance at which the elastic force becomes zero is changed so that a simulation of the stable conditions of the mass points is carried out again. Thus, even if the design of a garment is changed, a real time and precise simulation can be carried out.
A knit simulation device simulates a knit fabric knitted according to design data so that individual threads are three-dimensionally displayed. A plurality of nodes indicating thread positions in fabric loops are obtained per loop, and thread sections are disposed with respect to the obtained nodes and the disposed sections are connected to each other at corresponding portions between the sections. A twist between the corresponding portions is detected, and upon detection of the twist, non-corresponding portions between the sections are connected to each other to change the connections between the sections. This eliminates unnatural thread twists in the simulation.

DEVICE AND METHOD FOR DEBUGGING KNIT DESIGN AND DEBUG PROGRAM
The condition of a knitted stitch hooked on a needle of a needle bed, a needle operation, racking, a carrier position, etc. are tracked based on knitting data. Data to be failed are stored in a check table (32), and for the condition and operation of the needle bed, etc., data to be matched with the data on the table are detected as failure data. The failure of design data can be automatically detected.
Stitch arrangement data are divided into a plurality of blocks. Among stitches in a block the center of which belongs to a display area and stitches in blocks adjacent to this block, stitches are extracted in a part where a line connecting the starting point and the front edge of the stitches runs against the display area. With these stitches taken as display subjects, a 3-D image corresponding to a viewing direction is made out. This can provide a 3-D simulation image of a weaving ground for necessary points on a real time basis.
Conversion data 'D' from an original color space to a new color space is set to D = A • B-1, where 'A' is a profile for a printer in the original color space and 'B' is the profile for the same printer in the new color space. Even when the color space is changed, the same image can be outputted from the printer.
A 3-D simulation of a garment shape made of non-sewn knitting is carried out on a flat plane. The garment is divided into a plurality of parts and the parts are further divided by meshes to generate polygons. Each part is arranged around a manikin and the parts are joined to each other, so that a wearing state is simulated at a polygon level. Next, stitches are arranged for the polygons, the arrangement of the stitches is rectified, a 3-D shape of the stitch is set, and rendering is carried out by a thread image. This makes the simulation speed higher.
The parts of a garment are arranged at the periphery of a model of the human body, interference between the parts of the garment and the model of the human body is detected, and the interfering parts of the garment are separated from the model of the human body to eliminate the interference. A joining line is positioned between two parts of the garment which are to be joined together, and the ends of these parts are moved towards the joining line. If the end of a part of the garment comes into contact with the model of the human body while moving, the part is deflected. Then, the joining line is moved so as to accommodate the parts after the parts have been moved, and these movements are repeated until the joining line is in contact with the ends of the parts of the garment. Subsequently, the fit of the garment is simulated, taking into account the strain in the garment, gravity and interference with the model of the human body. Thus, it is easy to dispose the parts of the garment at the periphery of the model of the human body, and the parts of the garment can be joined in a natural state.
An image of clothes when a wearing state without other clothes to be layered is simulated is stored for every suit of clothes, and the order of inner and outer clothes to be layered is input. Stored images for the clothes are superposed, and a portion inconsistent with the input order is detected. The image of the clothes which should be outer is moved outside the image of the clothes which should be inner, and the wearing state of the layering is simulated based on the image of the outer clothes after the movement. The layering can be simulated in a short time.
Knitting data is changed into 3D-filament data expressing the positions of stitches, the connecting relations between the stitches and the kinds of the stitches, so that the virtual wearing is made on a human body model or a fabric. Layers of a knitwear are formed by setting a view point and a light source, by converting the stitches in the filament data into a 2D-stitch image, as viewed from a view point, with fluff, by overlapping the stitch images and by adding coordinates of an opacity and a depth direction. A ray tracing is performed in the layers of the knitwear, and average shadows by the knitwear are applied to the layers of the human body model or the fabric so that they are synthesized to a display image. The simulation image, which expresses the thread body and the fluff of the knitwear and which expresses the shadows of the knitwear on the human body model, can be created in a high quality for a short time period.
3D-filament data expressing the stitch positions in a knitwear and the connecting relations between the stitches is corrected to flatten the faces of the stitches. Next, a folding line is set, and the faces of the stitches are folded on the boundary face containing the folding line and normal to the knitwear. The stitch faces, which are folded on the inner side closer to the boundary face, and the stitch faces, which are folded on the side farther from the boundary face, are slid in the opposite directions so that the stitch faces are inclined and smoothed near the folded portions. It is possible to simulate the folded knitwear easily.
A color of a printed sample is measured to obtain a temporal change of its spectrum. Temporal changes of the other spectra are estimated from the obtained temporal change, they are converted to temporal changes of surface colors in a color space, and surface colors are estimated after a lapse of proper time from the print. Next, in order to obtain a desired surface color after a lapse of designated time, a profile is made out to convert the surface color into print data. After a lapse of proper time from a print, the print can be carried out to obtain a desired surface color.

SIMULATION DEVICE AND SIMULATION METHOD OF KNIT PRODUCT
A virtual garment is generated based on design data of a knit product, the garment is arranged flatly and then an original picture read in is aligned with the garment. Subsequently, the color value of a polygon on the surface of a loop constituting the garment is altered according to the original picture. The garment having an altered color value is deformed three-dimensionally according to user input. A knit product printed after knitting can be simulated easily.
A knitting yarn switching method and a knitting yarn switching device. When knitting yarns are being fed from thread cones (12b, 12a) to yarn feeders (13b, 14a), ends of the knitting yarns which have been fed to yarn feeders (14b, 13a) are held, and when knitting yarns are being fed from the thread cones (12b, 12a) to the yarn feeders (14b, 13a), ends of the knitting yarns which have been fed to the yarn feeders (13b, 14a) are held. Ending of the knitting yarns to be connected thus held and the thread cones (12b, 12a) is then carried out and holding of the ends is released for the knitting yarns to be connected. The knitting yarns which have been fed from the thread cones (12b, 12a) are cut between the ended portion and the portion which has reached the yarn feeder and the ends of the knitting yarns cut off from the thread cones (12b, 12a) are held.
A splice head which can enhance strength at the splicing portion. A plurality of ply yarns (70, 71) to be spliced is untwisted by jetting compression fluid from an untwisting nozzle hole (32). Subsequently, an impact is applied to the plurality of ply yarns (70, 71) thus untwisted by jetting compression fluid from an splicing nozzle hole (33). Since an impact is applied to the plurality of ply yarns (70, 71) after they are untwisted, entanglement of the plurality of ply yarns (70, 71) themselves and entanglement of fibers projecting from the plurality of ply yarns (70, 71) are complicated. Consequently, strength can be enhanced at the splicing portion of the yarns.
A splicer device which can be made compact and can close a cut for inserting a yarn provided in a splice head at the time of ending. A yarn (12a) to be ended is selected at a yarn selecting portion (3) from a plurality of yarns (12) held at a holding portion (13). The selected yarn (12a) and a yarn (12b) under use are guided by a yarn guide lever (14) and inserted into an ending hole (7b) through a cut (7a) in the splice head (7). A lid member (300) provided in the yarn guide lever (14) is arranged to be fitted in the cut (7a) of the splice head (7) under such a state as the yarn (12b) under use and the selected yarn (12a) are inserted into the ending hole (7b).
A knit goods simulation device converts design data of knit goods to myoneme data that express loops by myonemes. The knit goods simulation device expresses the loop by polygonal columns, divides side surfaces of the polygonal column into polygons, and stores the polygon apical coordinates in a polygon memory. The knit goods simulation device extracts loops in a simulation image displayed on a monitor, processes them at a graphic CPU, and limits the processing scope. Further, the knit goods simulation device stores a part of the apical data in a graphic memory so as to make its transfer from the polygon memory unnecessary. The knit goods simulation device can process a three-dimensional image at high speed.
The shape of a sheet material (5) is determined by scanning the sheet material (5) on a cutting bed (4) by using an imaging head (10). The imaging head (10) picks up the image of the sheet material (5) along a main scanning direction block by block. When imaging is performed up to an end section of the sheet material (5), the imaging head stops scanning, moves in a sub-scanning direction and starts subsequent main scanning. A scanning range is limited within a range where the sheet material exists, and the shape of the sheet material can be determined at a high speed.

Parts are made to correspond to the parts of a human body, such as a right arm, a left arm, torsos, a right leg and a left leg. Frames are created around the axes of the human parts, and the parts are wrapped around the frames. The parts are adjusted in positions by sliding and turning them. The parts can be easily arranged with respect to the human model.
The center line and lines at the right and left end parts are inputted to a base image from which a texture image is to be mapped, and a position of the base image closest to the view point is inputted as a point closest to the user. Right side of the point closest to the user of the body is approximated by one quarter of circle, and the left side is approximated by another quarter of circle so as to generate an elliptical arc representative of the horizontal cross-sectional shape of the body. The texture image is then mapped to the body using that elliptical arc. Thus mapping of the texture image to the body can be performed easily.

The trackball (16) inputs two-dimensional motion, and operation of the ring (14) inputs four-axis three-dimensional motion but does not input the two dimensional motion.
Three sheets or more of stitch data correction table are stored, knitting design, knitting width and knitting speed are determined from knitting data, and the correction table specifically used for every knitting part is switched. Course mark due to influence by knitting width, knitting design or knitting speed which cannot be eliminated by feedback control of thread length can thereby be prevented.
Parts of clothing are disposed in a 3-D space according to pattern data, and the parts are sewn up virtually according to sewing relations between them. A human body wire-form model is inserted into the sewn clothing, the model is expanded into a human body model, and the clothing is deformed based on interference with the model and stresses within the clothing to complete clothing dressed on the human body model. The parts that can be disposed and sewn up with disregard to interference with a human body can be sewn simply, and a high-speed simulation is possible due to non-deformation into an unnatural shape in an early stage.
Clothing is divided into rough polygon elements to simulate a dressing condition, and a force acting on each divided polygon element is calculated to effect deformation. When acceleration acting on each element of the clothing is nearly zero, the polygon elements are switched to fine polygon elements to proceed with simulation. It is possible to simulate the dressing condition of clothing in a short time and reality.
For the design data of a tubular fabric, a 3-D simulation image is generated by reversing the front/back attributes of the fabric and then the view point is altered by 180° to obtain a simulation image when the front/back of the fabric is reversed. A reversed image and a non-reversed image are displayed in parallel on a monitor such that the other image is also altered when one design is altered. The tubular fabric can be simulated by reversing the front and back, and design on the inside of a tube can be confirmed.
For the design data of a tubular fabric, the type of face/back stitch is reversed and overlap relation of stitch such as miss-above/miss-below is reversed. With regard to the center line of the fabric in the right/left direction, position of the stitch in the right/left direction is reversed thus reversing the relation of right/left connection of the stitch. The stitch is represented by a yarn after these reversals and the simulation image on the backside of the tubular fabric is created. The tubular fabric can be simulated by reversing the face and back, and the inside of a tube can be confirmed.

A suction device (5) is installed near a splicing nozzle (4) for splicing yarns by exposing them to a flow of compressed fluid, and the suction device and splicing nozzle are covered by a cover body (70). Covering the splicing nozzle (4) and the suction device (5) by the cover body (70) results that a closed space (71) in which the splicing nozzle (4) and the suction device (5) are disposed is formed at least when yarn splicing is made by the splicing nozzle (4). Fiber dust produced in yarn splicing are spliced is prevented from scattering in a wide space and remains in the closed space (71) covered by the cover body (70). The suction device (5) sucks the fiber dust in the closed space (71).
A splicer device small in size and prevented from having an operation failure caused by fiber dust. A yarn (12a) selected by a yarn selection part (3) from yarns (12) held by a yarn holder (13) is fitted by a yarn guide lever (14) into a groove (7a) of a splice nozzle (7) and spliced to a yarn (12b) in use. Then, the yarn (12b) in use is cut by a cutter (30) and switched over to another yarn. Yarn waste produced is sucked by a suction device (19). A base (2) has a partition wall (100). First and second motors (4, 5) for driving the yarn guide lever (14) and cutter (30) are disposed on the partition wall (100), on the opposite side of the yarn holder (13), the yarn guide lever (14), the splice nozzle (7), the suction device (19), and the cutter (30).
For each module on the design of knitting, its knitting program and a parameter on knitting are stored separately. When the knitting parameter is converted into a handle on GUI and displayed and a user operates the handle, it is accepted as input of the knitting parameter. The accepted knitting parameter and the knitting program serve as the design of a module. Each module of knitting can thereby be designed efficiently.
A color extraction area is specified in a natural image and a color in the area is extracted and spread. The spread image is displayed as a preview and the extracted area is modified when required. When the extracted area is confirmed, the number of colors is limited, a knitting pattern is spread to be configuration data. It is possible to easily design a radical new border pattern.
A carriage-mounted unit of a weft knitting machine enabling a reduction in size even if it has a large number of functions. A pair of stitch pressers (3, 4) are driven by the rotating motion of a motor (7) through one side drive mechanism (10) and the other side drive mechanism (20). The one side drive mechanism (10) and the other side drive mechanism (20) is provided with double-lift cams (11) and (21) to reduce a load on the motor (7). A cam drive mechanism (30) advances and retreats a bristle (5) being the other member to and from a trick gap part (6) so as to avoid its interference with the pair of stitch pressers (3, 4). Even if at least three of stitch pressers (3, 4) being a pair of members and the bristle (5) being the other member are so driven by the single motor (7) that each of these members is advanced to and retreated from the trick gap part (6) by the rotation of the motor (7), a part such as a groove cam plate reciprocating in the reciprocating direction of a carriage (2) is not provided in the unit, and therefore, the unit can be small-sized.
A method and a device for cutting/holding the warp of a weft knitting machine in which even a fabric using a warp fed from a warp insertion mechanism can be cut appropriately and the end yarn after cut can be held appropriately. In a weft knitting machine (1) into which a warp (4) can be inserted, a cut portion (14) is formed to intesect the warp (4) while reciprocating at an interval to a needle bed (6) in the longitudinal direction by swing operation perpendicular to the longitudinal direction of the needle bed (6), and lapping operation parallel with the longitudinal direction by the warp insertion mechanism (2). The warp (4) in which a cut portion (14) is formed is hooked to one or a plurality of knitting needles (7b) and held in place. The warp (4) is then cut by causing a blade (15) moving in the longitudinal direction of the needle bed (6) to act on the cut portion (14) thus held. The warp (4) existing on the warp insertion mechanism (2) side from the cutting position of the cut portion (14) is hooked to the knitting needle (7b) and held in place. Subsequently, knitting using the warp (4) can be started with the forward end kept held.
A method and a device for cutting/holding the knitting yarn in a weft knitting machine in which the ends of a large number of knitting yarns can be held in a fabric knitting region or in the vicinity thereof without requiring a holding mechanism. Since a controller (10) forms a transient portion (8a) between front and rear needle beds (2), and a holding portion (8b) by a knitting needle (4) on the side of a needle bed (2) on one side using the knitting needle (4) by a knitting yarn (8) that has finished knitting of a fabric (9) and is waiting for the next use in knitting of a fabric, the knitting yarn (8) can be held even if an extra device for holding the knitting yarn (8) is not provided. Since the holding portion (8b) can be provided in the knitting region of a fabric (9) or in the vicinity thereof, traveling distance of a yarn feeding member is shortened and productivity can be enhanced. Since a cutter (11) moves along the needle bed (2) to cut the knitting yarn at the transient portion (8a), it causes no trouble in knitting of the fabric (9).

WEFT KNITTING MACHINE CAPABLE OF INSERTING WARP AND KNITTING METHOD BY THAT WEFT KNITTING MACHINE
A weft knitting machine capable of inserting a warp which is a weft knitting machine that feeds a warp to a knitting needle only from a needle bed on one side, and which can knit a fabric by using a warp even with a knitting needle from a needle bed on the other side without requiring an extra yarn guide. A knitting method in such a weft knitting machine is also provided. When the hooks (19) of five knitting needles (17) are made to advance from a rear needle bed (23) to between the knitting needles (16a, 16b) of a front needle bed (22), a purl can be knitted by these five knitting needles (17). The knitting needles (16a, 16b) may not be made to advance from the front needle bed (22) to a tip part (20) one by one. Alternatively, a texture such as rib and links can be knitted using a knitting yarn which is fed as a warp by making the knitting needle (16) advance from the front needle bed (22) to the advancing range of the knitting needle (17) from the rear needle bed (23).
