COUPLER WITH ATTACHMENT MEMBERS BUILT INTO THE FRICTION TREAD SURFACE, TRAIN AND CONVEYOR

摘要

The invention relates to a coupler (10) including a tread surface (16) for a friction roller comprising a first portion (12) and a second portion (14); members (20, 40) for removably attaching the first portion (12) of the tread surface to the second portion (14) of the tread surface (16); the tread surface being continuous and the attachment members being built into the tread surface. The invention also relates to a train including cross-bars mutually coupled by a coupler such as described above and to a friction conveyor of the train. The invention is suitable for obtaining a friction conveyor system that is safer and reduces the multiplicity of drive points while guaranteeing the independence of the loads conveyed.
