Abstract
Spacer segments (24) of various thicknesses are attached to radially movable master segments (14) of a transfer ring (16) for gripping and transferring tread belt packages of different diameters. The spacer segments (24) are of a resilient material and may have molded arm members (32) with flexible, resilient ribs (42) for engaging edge portions (46) of the master segments (14). Handles (70) may be provided on the arm members (32) for bending the arm members (32) to install and remove the spacer segments (24). Axial movement of the spacer segments (24) relative to the master segments (14) is limited by circumferentially extending raised edges (58,60,66,68) on the cylindrical mating surfaces (26,28) of the master segments (14) and the spacer segments (24).
