Abstract
A system for stitching two parts of a shoe together includes a stitching machine with a head and a cylinder bed. The head has a needle base disposed on a lower end adjacent the cylinder bed such that the two shoe parts can be stitched together therebetween. A positioning mechanism has a curved drive frame and is capable of moving the curved drive frame in a rotating motion along the circumference of the curved drive frame and in a linear direction generally along an axis of the curved drive frame. A jig positions the two shoe parts with respect to one another and is coupled to the curved drive frame. The jig includes a curved support surface for supporting the two shoe parts.
