ABSTRACT:
Apparatus for temporary storage of successive portions of a continuous stream of paper sheets has a transporting unit which advances the stream along a horizontal path, a frame which defines for successive rotary cores an elongated guideway above the path, a two-armed lever which can support a fresh reel containing a supply of wound flexible band material at a level below the path, and chains which can transport successive cores from the inlet portion to the outlet portion of the guideway in parallelism with the path. The lever is indexible through 180 degrees and carries two spindles each of which can support a reel. The leader of the band on a reel on one of the spindles is attached to an empty core in the inlet portion of the guideway while a pawl intercepts the foremost sheets of the stream in the path and while the empty core is rotated by the belts of the transporting unit. The pawl is then retracted, and the sheets of the advancing stream are stored between the convolutions of the band which is wound onto the core. The core is transported to the outlet portion of the guideway while the supply of convoluted band and stored sheets thereon grows.
