Embodiment Construction

[0015] A first preferred embodiment of the present invention will be described below with reference to FIGS. 1A-3. The device for open selvedge thread of the first embodiment is provided at the end of the heald frame for open warp yarns (not shown) and with respect to the headstock forming the selvedge structure W at the end of the woven fabric (refer to FIG. 2 ) The frame is provided on the front side of the loom. A flat mounting plate 3 and a U-shaped mounting plate 2 are stacked on the rear surface of the upper beam 1 which forms a part of the loom frame in the stated order and is fixed by bolts 4 in a vertically upright state. An L-shaped mounting bracket 5 is fixed on the front surface of the mounting plate 3 by bolts 6 (or the surface of the mounting plate 3 faces the right side of FIG. 2 ).

[0016] A servo motor 7 serving as a drive motor is fixed to the mounting bracket 5 with bolts 8 . A motor shaft 9 protruding from the servo motor 7 toward the mounting plate 3 ha...

Abstract

Provided is a device using for opening selvedge line of loom. In the opening device, at least two selvedge lines are disposed on the side of the warp group and gripped by the harness wire. The harness wire is moved in order to reciprocate through the driving force driven from the actuating motor to form into the opening selvedge line. A rotor is disposed on the both side of the warp and connected to the revolving actuating motor. A swinging part is arranged on the side of the warp to process swaying motion. The rotor is connected to the swinging part through the connecting rod to arouse the reciprocating of the swinging part. The connecting rod is used for transferring the rotation of the rotor to the swinging part. The swinging part is connected to the harness wire through the link mechanism for the sliding host, wherein the sliding host is disposed to move linearly.

Description

technical field [0001] The present invention relates to a device for opening selvage threads for use in selvedges, scraps and the like in looms. Background technique [0002] The selvedge thread is juxtaposed with the set of warp threads used to form the waste edge, which captures the end of the weft yarn or the selvedge weave used to form the end of the woven fabric. Opening devices exist in a variety of configurations. [0003] Japanese Unexamined Patent Application Publication No. 10-503563 discloses a shedding device for shedding selvedge threads. In the described structure, the two selvedge thread guide elements holding the two selvedge threads and being linearly guided in the vertical direction are connected to the crank through a link. The crank is arranged on the motor shaft of the rotating stepper motor for reciprocating motion. [0004] In the above opening device, the swing of the crank provided on the stepping motor is directly transmitted to the selvage yarn ...
