Description

Device for adjusting space in filling yarns

The present invention relates to a device for controlling the spacing of the weft yarns of the weaving fabric, and more specifically, it is possible to adjust the spacing density of the weft yarn which is inserted by temporarily stopping the rotational movement of the winding drum wound during the weaving fabric. It relates to a horizontal weft spacing device of the weave fabric.

In general, the automatic weaving machine separates the supplied weft into two groups, and moves up and down alternately, and the weft close-up body is installed on the upper and rear oscillating body connected by the driving shaft and the connecting rod having the crank bent portion, On the side of the stand, the repia with the weft pull-out feeder at the tip is engaged with the drive gear which is rotated forward and backward by a separate driving device, so that the body moves backward along the swinging stage after completion of the vertical movement of the inclined group. When the drive gear rotates forward, the repia, ie, the creeper, is rapidly moved between the upper and lower inclined groups to receive the weft from the weft feeder and the cutting device on the other side, and then the creeper pulls the weft by the reverse rotation of the drive gear. When it returns, the body advances, completing one cycle of weaving.

In such a weaving process, the conventional horizontal weft is adjusted in a way that is interlocked with the press-rolling and isolation movement of the press roller. When the press-roller is separated from the side drum, the driven roller is installed to be pressed against the side drum. By connecting the press roller with the rotation transfer means, the press roller was driven through the driven roller in the side drum at the non-measurement to adjust the interval of the horizontal weft.

However, since this method manufactures a large number of parts around each roller and rollers, the cost of production increases, causing the price of the loom to rise.

The present invention has been devised to solve the conventional problems as described above, the object of the present invention is to weave the woven fabric to adjust the gap density of the horizontal weft that is inserted by temporarily stopping the rotational movement of the winding drum wound during weaving fabric It is to provide a horizontal weft spacing device of the fabric.
