Abstract
Successive stacks of overlapping paper sheets are delivered by tongs to an assembling station where the sheets of successive stacks are connected to each other by circular binders including rims having a T-shaped or an L-shaped cross-sectional outline and being receivable in T-shaped or L-shaped marginal recesses of the sheets. The binders are delivered into and are held in the form of a row in equidistant sockets provided in part in stationary and in part in movable supports at the assembling station. Portions of sheets of a stack at the assembling station are deformed against the adjacent binders to thus introduce the binders into discrete recesses of each sheet, and the thus obtained stationery products are removed from the assembling station longitudinally of the row of sockets.
