Abstract
A structure for weaving without outer leno yarns on an air jet loom eliminates the auxiliary selvage from both sides of the fabric being woven. A mechanical filling yarn clamp is disposed between the filling detector and suction source on the right-hand side of the loom for holding the ends of the picks during weaving. A suction source nozzle is mounted adjacent and exterior of a fringe cutter downstream of the temples on the right-hand side for removing pick trimmings cut by the fringe cutter. A combined clamp and cutter is mounted on the left-hand side of the loom adjacent the fabric edge to provide acceptable fringe length without subsequent trimming.
Claims17
In an air jet loom for weaving fabric, including a main jet, a reed, a suction source mounted on the opposite side of the reed from the main jet, temples, a fringe cutter mounted on the same side of the fabric being woven as the suction source, and downstream of the temples in the directin of woven fabric movement, and a filling detector between the reed and suction source:
- a filling fringe waste reduction means for eliminating outer or auxiliary leno selvage waste from both sides of favric being woven and avoiding the utilization of outer leno yarns, said waste reduction means including:
- a filling yarn mechanical clamping means operatively disposed between said filling detector and said suction source for holding filling yarns from said main jet;
- and
- a second suction source mounted adjacent and exterior of said fringe cutter for removing fabric ends cut by said fringe cutter.
In an air jet loom for weaving fabric, including a main jet, a reed, a suction source mounted on the opposite side of the reed from the main jet, and a mechanical clamping means mounted adjacent said suction source:
- a filling detector mounted on the end of the reed adjacent said suction source;
- pushing means to facilitate pushing of the filling yarn end into said clamping means;
- and a support for mounting said pushing means to said filling detector so that an aperture is provided between said filling detector and said pushing means for receipt of said clamping means.
A method of minimizing outer or auxiliary leno selvage from both sides of fabric being woven on an air jet loom without utilizing outer leno yarns, comprising the steps of:
- effecting combined mechanical clamping and cutting of the filling yarn at the loom left hand side immediately adjacent the left hand edge of the fabric being woven so that acceptable fringe length, without subsequent trimming, is provided on the left hand edge of the fabric being woven;
- and
- mechanically clamping the filling yarn ends at the right hand side of the loom to provide adequate yarn tension on each filling yarn over a period of time, beginning slightly before beatup and continuing until several picks later, so that the fabric edge is woven tightly without looseness or kinks.
In an air jet loom for weaving fabric, including a main jet, a reed, a suction source on the opposite side of the read from the main jet, and temples:
- a waste reduction means for eliminating outer or auxiliary selvage from the left-hand side of the fabric being woven and avoiding the utilization of outer leno yarns, said waste reduction means including a clamping-cutter means disposed on the same side of the fabric being woven as the main jet, said clampingcutter means consisting essentially of a spring clamp including a spring finger and a base, said base including a cutting edge facing in the direction of said spring finger, and a pivotally mounted cutting blade mounted for pivotal movement to cooperate with said base cutting edge to cut the filling yarn from the main jet, said spring clamp and cutting blade located upstream of the temples in the direction of woven fabric and located adjacent the edge of the fabric so that an acceptable fringe length is provided, and further fringe trimming is unncessary.
