Abstract
Rubber cloth splicing apparatus broadly comprising a forward vibrating conveyor, a butt-splicer, a backward vibrating conveyor, and a take-up conveyor. Each piece of rubber cloth is fed by the forward vibrating conveyor onto the rear table of the butt-splicer and is clamped in position thereon, whereas the precedingly spliced rubber cloth piece is fed backwardly by the backward vibrating conveyor onto the front table of the butt-splicer and is similarly clamped in position thereon. The two rubber cloth pieces are joined end to end without overlap as the rear table is forced into abutting contact with the front table. The take-up conveyor carries the spliced pieces of rubber cloth away from the butt-splicer via the backward vibrating conveyor by indexed movement.
