＃開昭５７−９６６８３号公報参照）。The unidirectional rotation of the drive cylinder, which rotates in the forward and reverse directions of the set angle in conjunction with the movable part of the sewing machine, is transmitted to the inner cylinder inserted inside the drive cylinder through the one-way latch @##. A conveying device has been in existence for a long time, which is attached to the end of the cloth by rotation of the roller and feeds cloth, etc.
#Refer to Publication No. 1983-96683).

が半減するという不都合がある。-i. When sewing leather, it is customary to apply a thin layer of oil to the surface of the leather (1) to reduce the frictional resistance between the presser foot of the sewing machine, When a feed roller made of synthetic rubber is used, the surface of the feed roller gets oily and slips between the feed roller and the leather, resulting in the inconvenience that the leather cannot be accurately fed by the corresponding amount of rotation of the feed roller. However, if a metal feed roller is used, the part corresponding to the feed roller will be scratched, and the scratches will appear in a striped pattern, reducing the product value by half.
そこで、この発明は上記の不都合を解消し、上記のよう
・な皮革の縫製においても皮革に１１ヲつけることなく

This elastic material layer 3 covers the roller body 1
The elastic material layer 3 is wrapped around the outer periphery of the clothing 2 (11 fl).
The surface is further finished so that the surface of the cloth 2 matches the tip of the needle 4 of the clothing 2.

うになっている。Here, the above-mentioned cloth feeding device attaches the end of the support shaft 10 (the third brother 17-m 11) supported by the arm of the sewing machine,
The end of the first arm 11 is connected to the second arm 1.
A roller support shaft 137al is attached to the end of the roller. Also, a reversal prevention mechanism 15 is provided on the outside of the roller support shaft 13, and the inner surface 14 is fitted thereinto to allow rotation of the internal rfj 14 in one direction between the two. Furthermore, a one-way clutch mechanism 17 is provided between the two cylinders to which a driving cylinder 16 is fitted on the outer side of the inner cylinder 14 and transmits rotation of the sub-cylinder 16 in one direction to the inner cylinder 14. The setting angle is simultaneously moved in the forward and reverse directions by the rocking motion of the seeding shaft 18 that is linked with the movable part of the sewing machine.
The rotation of the driving cylinder 16 in one direction is transmitted to the cylinder 14.

送ることができる。In the embodiments shown in FIGS. 1 and 2, a linear needle 4 is shown as the needle 4 provided inside the elastic material layer 3, but the shape of the needle 4 is not limited to this. For example, it is also possible to rub a dogleg shape as shown in FIG. By forming the needle 4 in a dogleg shape, it is possible to obtain two methods of use in which the force of engagement of the needle with the workpiece differs depending on the direction of rotation of the feed roller, and it is also possible to use the needle in the direction of the arrow in Fig. 5. In this case, the cloth can be fed without fuzzing.

共に、被縫製物を傷つけることなく送ることができる。As described above, the present invention uniformly distributes a large number of needles extending in the radial direction inside the elastic material layer, 1 and aligns the tips of the needles almost with the surface of the IAi elastic material layer. The object to be sewn is fed by the contact resistance on the surface of the elastic material layer and the engagement force of the needle (1).Thus, the object to be sewn can be reliably fed by a dimension corresponding to the rotation angle of the outer periphery of the elastic material layer. In addition, it is possible to send the workpiece without damaging it.
