ABSTRACT:
A machine wherein the sheets are held together by adhesive has an indexible turret with radially extending equidistant pockets for reception of stacks of sheets from a feeding device. The pockets transport the stacks past an aligning device, thereupon past an adhesive applying device which coats one edge face of each stack with a layer of adhesive, past a strip applicator which attaches a flexible strip to each adhesive-coated edge face, thereupon past a strip folder which converts each strip into a U-shaped body, and finally to a removing device which removes the thus formed pads from the pockets and transports them in a direction which at least substantially coincides with the direction of delivery of stacks to the pockets. The turret is indexible by steps each of which is a multiple of the distance between the centers of the inlets of two neighboring pockets, and the distance between the feeding and removing device is such that the removing device is bypassed at least once by the stacks and pads in the pockets of the turret to thus ensure that the adhesive can set prior to removal of the pads from their pockets.
