Cutter Mechanism Patents (Class 139/291C)
  • Patent number: 6155307
    Abstract: A knife carriage for face-to-face weaving machines has a supporting surface with interchangeable, adjustable sliding parts which direct the knife carriage in relation to a guiding section. A cutting instrument separates top and bottom fabrics from each other. The instrument has attachment(s) for a drive cord from a drive mechanism for the knife carriage. The sliding parts and the attachment(s) for the drive cord on the supporting surface have a device, which when tightened, makes the attachment line of the device coincide respectively with the contact line of the sliding parts with the supporting surface, and surface the contact surface of the attachment(s) with the supporting surface. The length of the supporting surface is smaller than the distance between the extremities of the sliding parts protruding in relation to the supporting surface in longitudinal direction of the knife carriage.

    Abstract: A weaving loom for producing at least one woven fabric web (9) with at least one laid-in selvage includes a weft thread cutting device (23) and an associated selvage laying-in device (14). The cutting device and the laying-in device are mounted relative to the loom machine frame so as to be adjustably movable across the width of the loom along a spreader table (11) with its associated spreader devices (10, 12, 26) and then selectively fixed at any desired width-wise position. The cutting device and the associated laying-in device can be arranged to be independently adjustable, or can be mounted on a common support member, so as to be adjustable in common or in unison with each other across the width of the loom.

  • Patent number: 5312132
    Abstract: An inflatable air cushion for use as a safety device in an automobile is made of two blanks cut from strips of fabric interwoven with one another along a seam extending along the peripheries of the blanks. The strips are initially flat, but include at least two side regions spaced from and on opposite sides of the central axis of the resulting cushion and running parallel to either the weft or warp threads of the fabric. These side regions are shrinkable under the influence of heat to a greater degree than a region lying between them to give each blank a convex shape and giving the cushion a more desirable rounded shape when inflated than if made with flat blanks. The ability to form the blanks into convex shapes by heat shrinking avoids the need for employing other more complicated and time consuming shaping procedures.

  • Patent number: 5265649
    Abstract: A full roll transferred from a cloth wind-up position in a weaving machine to a temporary full-roll storage position on a transfer carriage is prevented from rotation by meshing with a gear mounted stationarily. The transfer carriage is equipped with empty roll supporting arms and cutter supporting arms having free ends at which a cloth cutting mechanism is supported. An empty roll is supported by a holding device mounted at free ends of the empty roll supporting arms so as to be rotated by an empty roll driving motor. Owing to rotation of the empty roll, tension is applied to a cloth between the full roll and the empty roll so that it is cut by the cloth cutting mechanism in a tensioned stationary state.

  • Patent number: 5178193
    Abstract: Continuous production of a long bias cloth is accomplished by manufacturing a tubular fabric on a circular loom having a circular frame, reeds arranged on the frame and a shuttle for a weft rotatable along the frame. The fabric is removed from the loom under tension by a removal device comprising a primary pillar core with a plurality of caterpillars adjacent its outer periphery. Removal under tension prevents the formation of any edge portion causing folds and wrinkles in the tubular fabric. The tubular fabric is then spirally cut by a cutting device which has a secondary pillar core with a plurality of feed rolls adjacent its outer periphery. The feed rolls are capable of moving the fabric forward relative to its length, while the cutter is capable of moving circumferentially relative to fabric lengbth. A long bias cloth of high quality can be manufactured continuously, even when the warp and weft fibers used have high-strength and poor or low elongation.

The wire forms a flattened central portion shaped to form a semi-circular bow having a symmetrical shape with a curved outer edge ground to a feather cutting edge, an inner edge and two lateral flat faces parallel to each other along which the edges of the textile material are moved after being cut by combined mechanical and thermal action of the wire. The edges of the textile material are sealed thereby. Since the temperature of the wire can be kept relatively low, no ridges of melted material are formed along the edges of the textile material.

When a warp yarn is broken during the operation of the loom, one end of a mending yarn and the broken end of the broken warp yarn extending from the warp beam are tied together, and the other end of the mending yarn is passed through a corresponding heddle and a corresponding gap between the dents of a reed, and then the loom is restarted. A signaling device generates a signal after detecting the arrival of the free end of the mending yarn which was not woven into the cloth after the loom was restarted. The free end of the mending yarn is cut off automatically from the woven cloth by a cutter in accordance with the signal from the signaling device while the loom is in operation.

Second warp threads are fed through the shed-forming device of the loom and woven into the strips alternately so that portions of the second warp threads interconnect the strips. The interconnecting portions of the second warp threads are cut to disconnect the strips and to provide each strip with a plurality of knubs each having a deformed end portion. The second warp threads are fed through a storage mechanism, which is disposed upstream of the shed-forming device and which is so controlled that -- while the second warp threads are being woven into the respective strips -- the second warp threads are fed through the shed-forming device at a slower rate than that at which they are fed during the formation of the second warp thread portions interconnecting the two strips.

  • Patent number: 3961651
    Abstract: Apparatus for heat treating thermoplastic fabric at the loom is illustrated including an elongated housing extending across the full width of the loom having a passageway therethrough dividing the housing into opposed chambers, one of which carries a heating element and the other, a reflector so that the fabric is heated from both sides, and a gripping means is disclosed for tensioning the fabric in open width as it passes the heater means with a suction device for removing gases and fumes generated by heating of the thermoplastic fabric to elevated temperatures.

  • Patent number: 3961650
    Abstract: A method and apparatus are provided for cutting a plurality of patterned strips, suitable for labels, from a broadly woven fabric formed from threads of synthetic material on a broad fabric weaving machine. The weaving is carried out under low warp tension to produce a boxing condition and obviate weft arching. After weaving, the broad woven fabric is guided from the output of the machine at the point where the sley beats up the fabric towards the breast beam to inhibit movement in the reverse direction. This guiding is effected by passing the fabric into an undercut slot, round a bar, and out of the slot again. The guided fabric is then cut into strips and the cut edges of the strips are melted almost simultaneously to weld the same against rippling with the two functions being effected almost simultaneously by use of electrically heated wire/plate pairs arrayed across the width of the fabric according to the desired width for the strips.
