ABSTRACT:
An abutment area is formed in which two belts 5, 6 are in contact with and confront each other. Link chains 23 carrying carrier rollers 24 are arranged in such a manner that carrier rollers 24 are disposed alternately on the back face of belt 5 and the back face of belt 6, in zigzags. The upper end is connected to winch 25, while the lower end is connected to weight 29. Link chains 23 are wound by winch 25, and link chains 23 are connected to the upper frame 17. When link chains 23 are stretched by weight 29, a force is given to respective belts 5, 6 through carrier rollers 24. Link chains 23 are released from upper frame 17, then link chains 23 are lowered and folded so that carrier rollers are positioned to be convenient for maintenance. Corridor for maintenance is unnecessary, and so cost is reduced.
