Abstract
As tape moves through a closed loop, high-speed tape transporter (10) loops of the tape are accumulated and stored in a tape bin (64). The capacity of the tape bin (64) is increased by extracting air from and lowering the air pressure in the region of the bin (64) occupied by the loops of accumulated tape and inside the loops of tape sufficient to cause the accumulated tape to compress into tighter loops which occupy less space in the tape bin (64). Air extraction takes place through a vacuum port (95) which communicates with the interior of the tape bin (64) and which is connected to a vacuum supply (11A).
