A needle unit 1 for lamination has: a square-shaped base 2 having a magnet embedded therein; four lower-side needles 3, 3, 3, ... disposed on the lower surface of the base 2; and one upper-side needle 4 disposed on the upper surface of the base 2. Four ridges located at the corners of the square of the base 2 serve as reference parts 8 for aligning the upper-side needle 4 with a characteristic point of a pattern of a fabric. A first fabric is disposed on an iron-containing plate-like body, and the needle unit 1 for lamination is disposed on the first fabric in alignment with the characteristic point of the pattern. The needle unit 1 for lamination is pressed so as to cause the lower-side needles 3 to pierce the first fabric and also to be inserted into a resin film on a surface of the plate-like body, thereby fixing the needle unit 1 for lamination to the first fabric. A second fabric is disposed on the first fabric and the needle unit 1 for lamination. The upper-side needle 4 is aligned with a characteristic point of a pattern of the second fabric, and then the upper-side needle 4 is caused to pierce the second fabric. By aligning, with the upper-side needle 4, characteristic points of patterns of a plurality of fabrics and then piercing the plurality of fabrics, a laminate of the fabrics of which the patterns match each other is created.

A cutting apparatus cuts a fabric using a rotary blade and a fixed blade that are built into a cutter head. The fixed blade is linked, to the other-end side of a swing arm of which one end is pivotally fitted on a blade frame by a swing shaft. The fixed blade is urged by a coil spring connected to the one-end side of the swing arm. When a prescribed resistance force is applied to the fixed blade, a position sensor detects movement of the swing arm, a fixed blade drive cylinder drives the swing arm in response to the detection, and the fixed blade is moved to an accommodation position that is above the position during cutting and that is on an opposite side in the advancing direction of the cutter head.

A cutting apparatus cuts a fabric disposed on a support surface of a cutting table using a rotary blade 32 and a fixed blade 48 that are built into a cutter head 7 driven in a plane parallel to the support surface. The fixed blade 48 is linked, via a leaf spring 45, to an other-end side of a pivot arm 41 of which one end is pivotally fitted on a blade frame 30 by a pivot shaft 40. The fixed blade 48 is urged toward a support-surface side by a coil spring 42 connected to the one-end side of the pivot arm 41. When a prescribed resistance force from the fabric is applied to the fixed blade 48, a position sensor 55 detects movement of the pivot arm 41, a fixed blade drive cylinder 53 drives the pivot arm 41 via an elongated hole linking part 51 and a drive pin 49 in response to the detection, and the fixed blade 48 is moved to an accommodation position that is above the position during cutting and that is on an opposite side in the advancing direction of the cutter head 7.

Provided is a cutting apparatus (1), which can prevent a sheet material (10) from moving and being damaged even if a fixed blade (43) receives a resistive force from the sheet material, and which can prevent the fixed blade from being damaged. A cutter unit (4) of a cutting apparatus is configured of a pair of carriages (5) that travel along rails in the longitudinal direction of a cutting table (2), and a cutter head (7), which travels along a rail provided on a beam member (6) between the carriages. The cutter head has a rotating blade (29) and a fixed blade that is pressed to the blade edge of the rotating blade. The fixed blade is held by means of a fixed blade holder (42), which is pivotally supported to the leading edge portion of a blade spring (40) such that the blade holder can swing, and the fixed blade is held at a cutting position by attracting the fixed blade holder using a permanent magnet (44). When the fixed blade receives an excessive resistive force from a fabric (10), the fixed blade inverts and retracts in the direction opposite to the drive direction of the cutter head.

Provided is a device capable of accurately cutting a cloth without damaging the blades of cutters and without complicating a structure when the cloth is cut. A cloth loading member (sheet) (4) on which the cloth (5) to be cut is positioned and which is used for cutting the cloth by the cutters (31, 41) is made of a moquette.  Since the moquette is flexible, the cutters can be substantially prevented from receiving the damage resulting from the contact thereof with the cloth.  Furthermore, since the ends of plumes of the moquette are twined with the warps and wefts of the cloth, and the cloth to be cut is held at a predetermined position, the cutting accuracy of the device can be improved.
