Abstract
Sewing apparatus, especially a contour sewing machine for a sewing unit, comprising a vertically reciprocating needle (2) and a sewing material holder (7, 7′) which moves relative to the needle. This apparatus produces a seam having a predetermined shape. The holder (7, 7′) is moveable in directions (X, Y) extending at an angle to one another in a plane, the movements being generated by two independent motors (24, 40) and the holder (7, 7′) being releasably connectable to a bearer (14) driven in one direction (Y) and engaging a drive operative in the other direction (X). The holder (7, 7′) is mountable on a guide rod (5, 5′) rigidly connected to the bearer (14) and is connectable via at least one connecting element (12) to the drive for the other direction (X).
