Abstract
A roller cam with pairs of sliding surfaces and wear plates located in an upper plane and with pairs of laterally slanted sliding surfaces and pairs of laterally slanted guiding wear plates located in a lower plane. The guiding wear plates are longitudinally contained between end plates to avoid using screws, which might loosen under stress, to secure the wear plates. Adjusting setscrews are used to laterally adjust the guiding wear plates, and positive return members are used to provide a tool retracting force in addition to that provided by a retracting spring.
