ABSTRACT:
The present invention pertains to a feed mechanism for a sewing machine for displacement-free, near-edge connection of two flexible layers of fabric in the direction of sewing. The device, which is to be used as an attachment, consists essentially of a driven, endless feeding arrangement guided in the horizontal direction and a plurality of receiving elements which are designed as clamps. The receiving elements include clamp lower parts arranged at a vertically spaced location from the fabric support surface and clamp upper parts that can be actuated like pushbuttons, as well as a pressing element acting on the clamp upper parts.
With their edges that are to be connected, the fabric layers are fed into a flat feeding section and fixed and carried by a first clamp and continually fixed by consecutive clamps in the same position in the device, thus carried along the stitch formation site, and continuously released in the sewn state at a discharge point.
