ABSTRACT:
Apparatus for taking up and paying out first and second ends of an endless loop of tape that has an intermediate section. A first reel connected to the first end carries a first coil of the tape. The first coil extends from the first reel and is normally self-expanding and unwinding so as to unwind itself from the first reel. A second reel is connected to the second end for carrying a second coil of the tape. The second coil extends from the second reel and is normally self-expanding so as to unwind itself from the second reel. A drum supports both of the first and second reels for rotation in the same direction. Pulleys guide the intermediate section of the tape from the first reel to the second reel for moving a sludge collector. When the drum is rotated in a first rotary direction, the first coil tends to self-unwind from the first reel and the second coil is wound up on the second reel to move the intermediate section of the tape and the sludge collector. Upon rotation of the drum in a second rotary direction, the second coil tends to self-unwind from the second reel to apply tension to the tape and the first coil is wound up on the first reel to move the intermediate section of the tape and the sludge collector.
