no. 1 approach

[0025] based on Figure 1 to Figure 5 The first embodiment will be described. In addition, in this application specification, the figure 1 Let the left side be the front side, the right side be the rear side, and the upper side and the lower side will be described as the upper side and the lower side, respectively. figure 1 It is a side view of the pile loom, and the ground warp shaft 1 is driven by the delivery motor M2 electrically connected to the ground warp delivery control device C2.

[0026] The ground warp yarn TG sent out from the ground warp shaft 1 by the rotation of the delivery motor M2 passes through the arc-shaped rear guide plate 2 and the tension roller 3 to the plurality of heald frames 4A to 4D and the reed 5 . The reed 5 swings between a weft beating position shown by phantom lines and a weft insertion position shown by solid lines by a drive device not shown. The woven fabric W is wound up on the cloth winding roller 10 via the telescoping rod 6 , the l...

[0065] Figure 6 The second embodiment is shown, and the same configuration as that of the first embodiment will be described using the same reference numerals, and detailed description will be omitted. In the second embodiment, the opening curve of the ground warp yarn TG and the pile warp yarn TP has an angle of repose γ, and by changing the speed of the opening and closing of the ground warp yarn TG, the crossing timing K2 is made shorter than the crossing timing of the pile warp yarn TP. Early structure of K1.

[0066] The opening curve of the ground warp yarn TG increases the closing speed of the ground warp yarn TG accompanying the completion of the weft insertion of the second loose weft L2 to make the crossing time K2 earlier, and then reduces the opening speed in the reverse direction to be equipped with the injection of the tight weft F. latitude moment. In addition, when moving from the tight weft F to the first loose weft L1, when the weft insertion of the tight ...

Abstract

A method is provided for shed opening in a pile fabric loom. The pile fabric loom includes heald frames (4A, 4B, 4C, 4D) through which ground warp yarns (TG) and pile warp yarns (TP) are inserted, drive devices driving the respective heald frames, and a shedding controller controlling (C4) the drive devices separately so as to open and close a shed of the ground warp yarns and a shed of the pile warp yarns, and forms piles by loose pickings (L1, L2) of a plurality of times and fast picking (F) of one time that are performed in conjunction with forward and backward movement of cloth fell. The loose picking is followed by the fast picking. The method is characterized by setting cross timing (K2) to close the shed of the ground warp yarns (TG) earlier than cross timing (K1) to close the shed of the pile warp yarns at least during a transitional period from the loose picking (L2) to the fast picking (F).

Description

technical field [0001] The present invention relates to a warp shedding method of a pile loom provided with a ground warp and a pile warp. Background technique [0002] Patent Document 1 discloses a pile weaving method of a three-weft terry moving type pile loom, a ground warp yarn during pile weaving, and an open pattern of the pile warp yarn. The beating of the weft yarn is always carried out at the prescribed position, and the cloth fell reciprocates between the beating position and the position closer to the front of the loom than the beating position through the napping motion. [0003] In the case of weaving a pile weave of a three-weft towel, one cycle is formed by three weft yarns. Weft insertion and beating are performed with the first weft yarn and the second weft yarn advancing toward the front of the loom than the beating position (referred to as weft loosening). The third weft yarn performs weft insertion and beating (called tight weft) under the state that th...
