Abstract:

A web transport, such as a reel-to-reel magnetic recorder, includes a web regulator between one reel and a transducing station. In a constant tension web transport, web regulator ensures a relatively constant length of web between the transducing station and the one reel. In a preferred form the regulator is a vacuum chamber having a narrow web receiving opening and a wider cavity such that as the web forms a bight in the chamber into said wider cavity, air flows past the web to regulate bight size in accordance with web tension tending to maintain a constant web length.
