Abstract
Successive sheets of a stream of partially overlapping paper sheets are brought into contact with and are entrained by successive increments of an upwardly sloping running flexible band which is convoluted onto a rotary core to form with the sheets a bobbin wherein the sheets are confined between successive overlapping convolutions of the coiled band. The sheets of the stream are inverted ahead of the locus where they reach the running band so that the trailing portion of each preceding sheet overlies the leader of the next-following sheet. This reduces the likelihood of shifting of the sheets on impact against and during travel with the band upwardly toward the rotating core and renders it possible to dispense with a flexible element which is used in conventional apparatus to hold the sheets against slippage relative to the upwardly sloping band and which is convoluted with the band to thereby reduce the amount of space which is available in the bobbin for storage of confined sheets.
