CONVEYOR BELT MODULES WITH EMBEDDED ROLLERS RETAINED IN THE MODULES AND ASSOCIATED METHOD

摘要

A plastic conveyor belt module (24) with embedded rollers (34) retained in the module (24) and a method for making such a module (24). The module (24) includes a module body (42) forming a cavity (36), a roller (34) in the cavity (36), and a retainer (46) received in the cavity (36) to hold the roller (34) rotatably in place. A salient portion of the roller (34) extends outward from the cavity (36) through the retainer (46) past an outer surface (32) of the module (24). The retainer (46) is attached to the module body (42) by ultrasonic welding, epoxy- or solvent-bonding, spin welding, electromagnetic welding, staking, screwing, or locking.
