方向に回転可能である。When the connecting portion 30 in FIG. 3 is moved in the direction of the arrow by the back and forth movement of the horizontal axis 20, when the connecting portion 30 moves rightward in the drawing, the rotating drum 24 is moved in the direction of the arrow intermittently through the annular body 22. The puller shaft 10, which is moved and inserted into the rotating drum 24, also moves in the same direction. Contrary to the above, the connecting portion 30
When the puller shaft 10 moves to the left in the drawing, the puller shaft 10 remains stopped by the action of the one-way clutch disposed within the rotating drum. Therefore, by repeating the above motion, the puller shaft 10 can be rotated intermittently in a fixed direction together with the rotating drum 24.

部６６を具えた三個のアイドラー６８を用いる。The rotation of the puller shaft 10 is transmitted to a pair of drive pulleys 34 mounted on this shaft, and this movement is further transmitted via a synchronizer belt 35 to a pair of drive pulleys 46 fixed to a horizontal pulley 37 installed below the work table 38. The horizontal shaft 37 rotates. This rotation is transmitted to the fabric feed drive pre-drive 50 via the other one of the drive spools 46 and the synchronized belt 48. However, the fabric feed drive unit 50 has a fabric feed drive unit 41 to which a fabric feed drive group 44 is attached.
As the shaft 41 rotates, the belt 36, which is wrapped around the fabric feeding group 44vc, is driven in a predetermined direction. In the embodiment of the present invention, three fabric pres 44 are used on the right side of the table 38, and one fabric feed 9 drive pres 50 and three fabric pres 44 are used on the left side. In order to adjust the strength of the belt 36 and make the rotation speed appropriate, three idlers 68 are used below the table 38, each having an arm 66 that can move up and down.
