ABSTRACT:
A device for use on a sewing unit in sewing and cutting-open tucks on cut pieces of garments, comprises a sewing machine having a stitch formation zone which operates in conjunction with a work advance table. The work advance table has an edge around which the work is folded and a template rail is supported from the support for the work table and includes a pressure plate portion which may be moved into association with the work and a template rail which provides a guide for the feeding of the work piece into association with the sewing needle so that the shape of the seam may be followed. The apparatus includes a cutting knife which is carried on a carrier plate which is pivotable backwardly and forwardly. The cutting knife comprises a rotatable cutting blade which is rotated by a motor on the pivotal carrier plate. The carrier plate also provides a pivotal support for a guide spur which is in the form of a wedge-shaped plate which has a slot therein through which the blade extends and which includes an outer knife-like edge which engages into the space between the two materials. For this purpose, the work advance table is formed at least partly with a forked cross-section having spaced apart top and bottom legs defining a slot therebetween or an opening for the introduction of the guide spur so that the cutter is guided along the edge of the fabric to effect its cutting operation.
