ABSTRACT:
Successive stacks of overlapping paper sheets are transported toward a sewing station where the sheets of successive stacks are sewn together by a sewing machine. In order to reduce the generation of heat at the sewing station and the resulting breakage of thread and damage to the needle or needles, successive stacks are provided with rows of holes ahead of the sewing station. The distribution of holes in the stacks and the mode of transporting stacks toward and through the sewing station are selected with a view to ensure that the needle or needles penetrate into the prefabricated holes with a minimum of friction. The surplus of thread is trimmed off the products downstream of the sewing station. Such products can constitute books, brochures, pads or other commodities containing stacks of sewn together sheets of paper or other sheet material.
