Abstract
A pulley or sheave that is lagged with rubber or rubber-like material, has two disc-like members which are disposed broadside to each other and secured together to form an annular groove for receiving and guiding a strand of material. At their centers, the members have bearing means to accommodate a spindle. In the annular groove for the strand of material the members have oppositely disposed wall portions characterized by re-entrant side walls. A wear strip of relatively soft, resilient material such as rubber having an elongated rib occupies the annular groove, the rib being accommodated in and frictionally seized by the reentrant side walls. The wear strip has abutted ends, and presents an annular exterior space for engagement with the strand of material that is being handled.
