ABSTRACT:
A storage buffer for a moving web comprises a collection bin having a bottom triangular cavity, a top opening through which the web can be randomly dumped under the influence of gravity and a bottom opening through which the web is withdrawn from the collection bin on a first-in, first-out basis. The sloping bottom walls of the collection bin are provided with ridges to assure the maintenance of a gas bearing beneath the bottom-most layer of exiting web. Nozzles for directing pressurized gas into the collection bin are located on both sides of the web at the collection bin exit.
