| 1 | Catch-cord drawing device for looms | US618664 | 1984-06-08 | US4616680A | 1986-10-14 | Pepper Y. Lai |
| The catch-cord selvage of a shuttleless or fluid jet loom is drawn between a pair of mating rollers having smooth surfaces under a prescribed tension that is matched to the fabric tension as it comes from the loom. The mating rollers include an idler roller which is driven by a drive roller, with the drive roller being positively driven without slippage by the fabric take-up roll. The surface speed of the drive roller is the same as the surface speed of the fabric take-up roll so that the catch-cord and the fabric are drawn from the loom at the same speed. | ||||||
| 2 | Method and apparatus for waste selvage removal | US401694 | 1982-07-26 | US4453572A | 1984-06-12 | Worth M. Key |
| Waste selvage containing warp ends or leno yarns interlaced with filling tails is removed from a shuttleless loom. The loom includes a suction source having an impeller pump with an exhaust, with fabric being removed by a fabric take-up roller. A venturi is disposed below the fabric take-up roller in operative association with waste selvage from fabric being taken up by the roller, the exhaust from the impeller pump being connected to the venturi to provide the motive power for the venturi to suck waste selvage through the venturi and deposit it in a waste selvage container. Draw-off wheels are provided between the venturi and the fabric take-up roller, the venturi preventing the selvage from clinging to the draw-off wheels, and being wound onto the wheels, without any energy penalty. A baffle at the venturi induces rotary turbulence to cause the filling tails and warp ends or leno yarns to twist together so the filling tails will not be blown away by air passing through the venturi. | ||||||

| 4 | DEVICE FOR COMPACTING AND DISCHARGING WEFT WASTE IN AN APPARATUS FOR REMOVAL OF THE WEFT WASTE FOR WEAVING LOOMS | EP99931407.3 | 1999-07-29 | EP1639167A1 | 2006-03-29 | CAPITANIO, Osvaldo |
| Device for compacting and discharging weft tail-end waste of weaving looms, in a system for removal of said waste comprising a pneumatic conveying duct (1) connected at one end to an inlet mouth (2) for the weft tail-ends and at the other end to a storage container. A portion of the conveying duct (1) provided with an output filter for the conveying air comprises a motor-driven screw element (7) for entangling said weft tail-ends. An outlet aperture of said portion of the conveying duct may be closed by valve means (9, 10, 11) for regulating the expulsion of the entangled and compacted weft tail-ends into said storage container. | ||||||

| 6 | Leno selvaging and stretch nozzle system | US462977 | 1983-02-01 | US4513791A | 1985-04-30 | Douglas M. Dillon |
| A leno selvage and stretch nozzle system for an air jet loom utilizing a Venturi device receptive of pressurized air from the air jet system to provide vacuum at a tensioning nozzle mounted on the loom reed. The Venturi device exhausts into a second Venturi device, which receives the leno selvage to direct the leno selvage into a waste container. | ||||||
| 7 | Positioning and holding mechanisms for filling yarns in a shuttleless loom | US906982 | 1978-05-17 | US4185667A | 1980-01-29 | Edd H. Kendrick |
| In a shuttleless loom for weaving repeating patterned fabrics including rapier mechanisms for inserting picks of selected ones of a plurality of filling yarns, a filling yarn pattern control mechanism for selectively presenting desired filling yarns at predetermined intervals to the rapier mechanism, cutter mechanisms for cutting the selected filling yarn when received by the rapier mechanism, and selvage trimming mechanisms for trimming the loose filling yarns extending outwardly from the woven fabric; the improvement is provided of mechanisms for positioning and holding the loose cut and uncut ends of filling yarns for trimming by the selvage trimming mechanisms and for continuing to hold under tension the cut ends of those filling yarns for which a repeat pick has not yet been called for in the repeating pattern of the fabric after cutting thereof by the selvage trimming mechanisms and, thereby, eliminating the prior necessity and cost of weaving false selvages which performed such positioning and holding actions and which were cut off by the selvage trimming mechanisms as waste. | ||||||
| 8 | Device for the recovery and removal of a false selvedge in a shuttleless loom | US3670779D | 1970-12-23 | US3670779A | 1972-06-20 | DEBORDE ALBERT |
| A false selvedge in a shuttleless loom is recovered by continuously winding the false selvedge under tension on the larger end of a conical bobbin, the wound selvedge moving progressively to the narrower end of the bobbin at which it progressively falls on to the floor or into a storage receptacle.

| A false twisting device of a shuttleless loom is characterized by preventing front and rear motions of a catch cord in a front of the loom, installing a rotary spindle to make the catch cord curved on a guide edge of an end of the rotary spindle, giving twist to the catch cord by using frictional resistance and preventing transmission of twist of the catch cord from deteriorating. A false twisting device(10) containing a rotary spindle(20) twisting a catch cord(2) comprises: an endless type guide edge(21) installed on an end of the rotary spindle to accord a center axial line crossed at right angle to an inside of the guide edge to a rotary axial line of the rotary spindle; and the rotary spindle. An axial direction of the rotary spindle is at right angle to a warp direction. The rotary spindle is characterized by curving the catch cord passed through an inside of the guide edge and extended upward on the guide edge. A guiding device installed on the false twisting device contains a guide member. The guide member contains the endless type guide edge. The guide member of the guiding device is installed on a circumference of an inside center of the guide member and is capable of being rotated. | ||||||
