ABSTRACT:
Apparatus for variably buffering a web material, the apparatus having two endless transport belts including feed sections in which the belts are juxtaposed, and return sections, the feed and return sections being of varying lengths. In the feed sections, the belts move through a U-shaped path portion, commonly guided over a deflecting roller. In the return sections, the belts are guided through U-shaped path portions extending opposite to the U-shaped path portion of the feed sections, each belt wrapping separate deflecting rollers. The three deflecting rollers are rotatably supported on a common mounting frame movably held in a machine stand for compensated length variation of the feed and return portions.
