Abstract
Apparatus for temporary storage of a stream of partly overlapping paper sheets has a first core which is driven by a first motor in a direction to collect an elastically extensible band while the band receives a succession of sheets which are thereby confined between successive convolutions of the band on the first core. The band is drawn from a second core which is braked with a gradually decreasing force so that the product of such force and the radius of the growing roll of sheets and convolutions of the band on the first core is at least nearly constant. The elongation of the band during winding onto the first core is not less than 0.1 percent.
