ABSTRACT:
In a trimming sewing machine a chain (16) is formed on a workpiece (5) at the end of a stitching, which chain must be then cut and reversed over the needle plate (2) before starting of new stitching. The chain (16) is formed on a primary tab (12) provided on a side edge (11) of the needle plate (2) and an auxiliary tab (13) disposed parallel to and in side by side relation with the primary tab (12). A chain-cutting member (17) draws the chain (16) in, disengaging it from the auxiliary tab (13) and separates it from the sewn workpiece (5). A first nozzle (20) oriented perpendicular to the sewing direction reverses the cut chain (16) over the needle plate (2). Simultaneously, a second nozzle (22) is activated and it projects an air blow towards the end (13a) of the auxiliary tab (13) so that the chain (16) on reversal is prevented from stepping over the auxiliary tab (13).
