ABSTRACT:
A feed device for feeding a material pattern cut to a sewing machine for the forming of stitch groups such as a row of button holes by a reciprocating needle operating on the material pattern which is advanced through the needle path and moved in a draw-off path, comprising a draw-off roll arranged alongside the needle in a position to engage the material. The draw-off roll is arranged on a shaft which is coupled through a sleeve to another shaft containing a transport roller forming part of a material transport. Drive means are connected to drive the shafts of the draw-off roller and a laterally arranged transport roller and a drive belt is interconnected between the transport roller and a second transport roller which extends rearwardly thereof and is located at the turning point of the material draw-off. This second transport roller has a higher circumferential speed than the first transport roller and it protrudes through an opening in a lead guide for the material to engage the material and send it off in a draw-off direction. The apparatus also includes a deflecting bar which is oriented to contact the material at the location of the first draw-off roll. The free length of the rod corresponds substantially to the expanse of the pattern cut in the region of the deflecting edge of the lead guide.
