Cuts are formed in the woven fabric along transverse sections of each tear line, the transverse sections running essentially transversely to the longitudinal extension of the web material, which cuts are spaced apart from each other and are oriented in the longitudinal direction of the web material or transversely to the transverse section of the tear line, with the cuts being connected to only one transverse section of the tear line.

ANTISLIP FLEXIBLE MATERIALS AND METHODS FOR THEIR MAKING AND USE
A method for forming an antislip material. A flexible thermoplastic carrier (13) is provided. A hot release surface (45) is provided. Provided is a first layer (29) of discrete thermoplastic particles (39), sitting on the hot release surface (45). The discrete particles (39) are above their softening temperatures, providing in the first layer (29) a tackiness. The method includes contacting the carrier (13) with the tacky first layer for sticking the first layer (29) to the carrier (13), and thereafter removing the carrier, and therewith the tacky first layer stuck to the carrier, from the release surface (45). Thereby the carrier (13) is provided with a hot, preferably discontinuous and/or elastomeric antislip coating. With a heat energy of the hot coating a bond is formed between the carrier and the coating. The removing of the carrier (13) includes pulling the carrier out of the contact with a pulling-out force. The temperature of the hot release surface (45) is above the melting temperature of the carrier (13). The carrier would be spoiled, if heated completely to the temperature of the release surface and simultaneously pulled with the pulling-out force. Therefore the contacting time is kept shorter than a minimum time required by a heat of the hot release surface (45) for spoiling the carrier (13). Flat-topped roughening projections (31) can be included in the antislip coating.

A method for applying a band of material to a flexible-tube piece (1) made of coated or non-coated woven plastic fabric. At least one strip-like band (3) of material is advanced up to the one end region (4) of the flexible-tube piece (1), and therefore one end (2) of the flexible-tube piece (1) overlaps in the end region (4).

Thereafter, the band (3) of material and the flexible-tube piece (1) are pressed together in the end region (4), wherein the thermal energy is introduced at the same time as the at least one band (3) of material is advanced up to the end region (4) of the flexible-tube piece (1). The method is characterized by at least one method step for forming a bag-opening surround (10) from the at least one band (3) of material.

DEVICE FOR PRODUCING AND SMOOTHING PLASTIC FILMS OR PLASTIC PLATES
The invention relates to a smoothing device for plastic films comprising plastic-melt-producing means (1), an adjustable slit die (10), and a roller smoothing unit (16) having cooled smoothing rollers (11, 12), which form an adjustable smoothing gap (13) between each other. Further cooling rollers (15) are optionally arranged downstream. A thickness gauge (23) measures the thickness of the plastic-film web (22). A setpoint thickness (SD) of the plastic-film web (22) and the volumetric flow rate (SS) of the plastic melt or the line speed (LS) can be set by a controller (30) for controlling the thickness of the plastic-film web (22). The controller (30) captures the current torques and rotational speeds of the rollers (11, 12, 15) and the current thickness (FD, FD1-FDn) of the plastic-film web (22). The controller (30) sends setpoint rotational speed signals (C0S, C2S-CnS, CAS) calculated from the captured torques of the rollers (11, 12, 15) to the drives of the rollers and a smoothing-gap setpoint distance signal (GW) for adjusting the smoothing gap (13), and furthermore – in the case of a specified line speed (LS) – setpoint plastic-melt volumetric flow rate signals (SS) to the plastic-melt-producing means, or – in the case of a specified plastic-melt volumetric flow rate (SS) – setpoint line speed signals (LS) to the drives of the rollers (12).
A device (1) for producing bags from tubular bag bodies (10) comprises a transport device (2) which transports the bag bodies in a flat manner transversely to the longitudinal extent (L) thereof in a transporting direction (T) at a transport rate (V). While being transported, the bag bodies pass through processing stations (30, 40, 50, 60, 70, 80) by way of which at least one end region (13) of each bag body is formed into a cross bottom and optionally a cover sheet (19) is applied to the cross bottom. A transfer device (4) moves the bag bodies (10) to be transported by the transport device at a transfer rate (U), with respect to bag bodies conveyed at a transport rate (V), by a feeding distance (Δy) in the transporting direction (T) and then transfers them to the transport device (2). The feeding distance (Δy) is selected such that successive bag bodies overlap one another, wherein the overlapping width preferably corresponds to once or twice the height (h) of the triangular corner fold (14) which is produced when the bottom side flaps (15, 16) are folded over.
The device (1) for cooling adhesive (23) applied to a surface (24) of sack bodies (20) comprises a transfer conveyor (2) and a cooling conveyor (4). The transfer conveyor (2) conveys the sack bodies (20) at a transfer speed (3) to the cooling conveyor (4), and the cooling conveyor (4) conveys sack bodies (20), taken from the transfer conveyor, at a cooling conveyor speed (5). The transfer speed (3) is higher than the cooling conveyor speed (5), as a result of which the sack bodies (20) overlap each other on the cooling conveyor. By means of this higher packing density, a long dwell time of the sack bodies (20) in the cooling conveyor (4) is achieved, with at the same time a high throughput of sack bodies (20) through the device.

DEVICE FOR CONTROLLING THE WEFT BAND TENSION ON A SHUTTLE, SHUTTLE AND CIRCULAR LOOM EQUIPPED THEREWITH
The invention relates to a device for controlling the weft band tension (FS) on a shuttle (30) of a circular loom, wherein the shuttle (30) comprises a band redirecting apparatus (3) and a weft band spool (1), from which a weft band (2) can be pulled off over the band redirecting apparatus (3). The weft band tension (FS) that occurs when the weft band is pulled off deflects the band redirecting apparatus (3) against a restoring force (FR). The control device (20) comprises: a deflection sensor (5), which detects the instantaneous position of the band redirecting apparatus (3) and generates a deflection signal (5a) as a function of the detected position, an arithmetic-logic unit (12), to which the deflection signal (5a) can be fed, and a variable electromechanical load (6, 14), which exerts a variable braking torque (7) on the weft band spool (1) according to a controlled variable (u). The arithmetic-logic unit (12) calculates the controlled variable (u) for setting the variable electromechanical load (6, 14) from the deflection signal (5a) fed to the arithmetic-logic unit so that a target value of the position of the band redirecting apparatus (3) and thus also a target value of the weft band tension (FS) are set.
The invention relates to a device for driving a shuttle (1, 1') that can be moved in the reed (17) of a circular loom along a circular orbit (16) without contact, comprising at least one permanent magnet (29, 29') on the shuttle (1, 1') and at least one magnet (22, 22') that is operatively connected to the at least one permanent magnet (29, 29') of the shuttle (1, 1') and that is arranged on a drive element (10) that can be moved concentrically to the orbit (16) of the shuttle, wherein an air gap (11) is formed between the shuttle (1, 1') and the drive element (10). The at least one permanent magnet (29, 29') of the shuttle (1, 1') and the at least one magnet (22, 22') of the drive element (10) are polarized in such a way that the at least one permanent magnet of the shuttle and the at least one magnet of the drive element mutually attract each other by means of magnetic forces and thus form a magnetic attraction section (14).
