Abstract

A machine for automatically roughing the cement margin of a footwear upper assembly. The machine includes means for supporting the footwear upper assembly by a mechanism capable of applying to the upper assembly rocking movement, translational movement and rotational movement. A roughing tool is provided, as well as means for applying a combination movement to the upper assembly. Simultaneously, roughing is effected along the shoe margin by the roughing tool. The combination of movements serves continuously to present a new roughing surface to the roughing tool in the course of roughing, resulting in uniformity of roughing. The rotational movement serves to cause the roughing tool to track the cement margin with a determined orientation therebetween as the cement margin moves past the roughing portion of the roughing tool.
