Transfer Ring Having Advantaged Cam Follower-Camming Groove Aspect and Method

摘要

A transfer ring especially suitable for use in the manufacture of vehicle tires including a skeletal cylindrical cage which houses an oscillatable circular drive member therewithin. The drive member includes a plurality of cam followers disposed about the outer perimeter thereof and which operatively engage respective camming grooves defined in each of a plurality of hinged driven links which are individually hingedly mounted internally of the cage about the outer perimeter of the cage. Each driven link includes an inboard end hinged within the cage and an outboard end having an articulating shoe mounted thereon. The shoes on the several driven links are interconnected to provide like simultaneous substantially equal articulative and rotational movement of the shoes radially inwardly or radially outwardly of the cage upon rotational movement of the drive member and resultant rotational movement of the hinged driven links effected through the cam followers and camming grooves of the driven links.
