Abstract

A device for manufacturing a multiple layer rubber strip including a first rubber strip and a second rubber strip, the device includes a first rubber extruder for extruding the first rubber strip, a second rubber extruder for extruding the second rubber strip, a first conveyor for conveying the first rubber strip extruded from the first extruder to a downstream side in a convey direction, and a second conveyor for conveying the second rubber strip extruded from the second extruder to a downstream side in the convey direction. The second conveyor is located upwardly of the first conveyor and has a downstream conveyor end which positions above a conveying surface of the first conveyor such that the second rubber strip delivered from the downstream conveyor end meets and overlaps the first rubber strip on the first conveyor at a joining location to form the single multiple layer rubber strip.
