In order to achieve the above-mentioned object, the present invention provides an endless structure that is circulated by a supporting shaft and a guide rail and a forward / reverse rotation device above a transfer roll that is rotated in the circumferential direction by a transfer drive device to feed out the dough. Is arranged substantially parallel to the transfer roll, and the vertical wire drawing tool is urged toward the cloth feeding side of the support shaft in the direction of coming into contact with the cloth so that the support shaft is pivoted up and down. A movable member, which is freely provided and has a bell crank pivotally supported by a pivot in a plane parallel to the guide rail, is attached to the guide rail by fixing one end of the bell crank to the cord. It is attached movably along with, and at the other end of the above-mentioned bell crank, is rotated in the forward direction together with the bell crank in the forward direction of the above-mentioned rope and is crimped to the fabric, and in the opposite direction of the rope. The crawl on the bell Rotates in the opposite direction with click is obtained by a configuration in which the horizontal line for drawing tool is separated from the fabric was attached.

[Action]

A vertical wire drawing tool and a horizontal wire drawing tool are attached to the support shaft and the bell crank, respectively, to prepare. Then, in order to draw a vertical line on the cloth, the vertical wire drawing tool is brought into contact with the cloth set on the transfer roll, and the transfer roll is rotated by the transfer drive device while the horizontal wire drawing tool is separated from the cloth. . Since the cloth is transferred by passing through the vertical wire drawing tool by the rotation of the transfer roll, the vertical wire is drawn by the vertical wire drawing tool.

Further, in order to draw a horizontal line on the fabric, the transfer driving device is stopped, the feeding of the fabric is once interrupted, and the rope is circulated in the forward direction by the forward operation of the forward / reverse rotation device. When the rope runs in the forward direction, the movable member moves along the guide rail,
At this time, the bell crank is rotated around the pivot axis by the pulling accompanying the circulation of the rope to bring the horizontal wire drawing tool into contact with the cloth, so that the horizontal wire is drawn on the cloth.

After drawing the horizontal line, the forward / reverse rotation device is rotated in the reverse direction to move the movable member in the reverse direction and return it to the original position. At this time, the bell crank rotates in the opposite direction around the pivot due to the backward circulation of the rope, so that the horizontal wire drawing tool is separated from the cloth.
