Abstract

A scalloped stream of paper sheets is intermittently transported from a sheet feeding unit to a reservoir wherein one portion of a flexible elastic band convolutes the sheets around a core. The sheets are thereupon transported over a switchover device and onto another portion of the band which convolutes the sheets around a hub while the core pays out the one portion of the band. If the sheets are needed at one or more consuming stations, the hub is rotated in a direction to pay out the other portion of the band and the switchover device directs successive sheets from the other portion of the band into or onto a sheet removing unit. The switchover device and the one portion of the band define a first transfer station where the sheets coming from the feeding unit reach the upper side of the one portion of the band and where the sheets leave the one portion of the band on their way toward and onto the other portion of the band. The other portion of the band and the switchover device define a second transfer station where the sheets coming from the one band portion and advancing over certain conveyors of the switchover device reach the other band portion and where the sheets leave the other band portion on their way over a conveyor of the switchover device and to the sheet removing unit. When the core pays out the one portion of the band, the hub collects the other portion of the band, and vice versa.
