ABSTRACT:
Partly overlapping sheets of a scalloped stream of sheets are transported against one side of a flexible band which is being convoluted onto a first core so that the sheets form convolutions which alternate with the convolutions of the band. The latter is drawn off a second core which is coaxial with the first core, and such band is trained over a set of pulleys which cause it to advance substantially tangentially of and between the axial ends of the first core. The two cores can be driven and braked independently of one another and are mounted in a common frame. The second core is driven by a shaft which rotatably mounts the first core.
