ABSTRACT:
Apparatus for pulling the lasting edge of a lasted shoe upper over an insole has at least one flexible elastic shaft one end portion of which is anchored in a motor-driven rotor and which is loosely surrounded by a helical spring. One end of the spring is anchored in the rotor and its other end is movable axially of the shaft toward and away from the one end. The spring yields in response to the application of an excessive pull to the lasting edge and thus prevents overstressing of the lasting edge and/or the development of wrinkles.
