ABSTRACT OF THE DISCLOSURE A cutting apparatus for cutting a strip of tape connected to a shoe upper component and extending beyond the edges thereof includes a blade for cutting the tape and presser feet for tensioning the tape during cutting. The blade and presser feet are independently, actuated by plungers, which are slidable in a casing mounted on the sewing machine used to sew the tape onto the upper component. The plungers are provided with magnetic cores, and separate coils around the cores are energized in response to signals from photosensors in the work surface of the sewing machine to effect tensioning of the tape, followed by cutting at the edge of the upper component. Springs in the casing around the plungers return the plungers to a rest position, and the tape tensioning and cutting operations are repeated at each component edge.
