ABSTRACT:
A roughing machine for operating on a shoe assembly, comprised of a last having an insole located on its bottom and an upper mounted thereon with the upper margin lying against and being secured to the periphery of the insole, by roughing the upper margin. The machine includes a roughing tool that is mounted to a tool mount. The tool mount includes a pair of tines that are yieldably urged against the bottom of the shoe assembly that is supported bottom-up in the machine and a sensing member that is movable from an idle position to a position of engagement with the side of the shoe assembly. A triggering arrangement causes the sensing member to move into engagement with the side of the shoe assembly in response to the engagement of the tines with the bottom of the shoe assembly.
