Abstract
A machine for cutting and folding an uninterrupted printed web of paper to produce folded sections includes a cutting cylinder cooperating with a transfer cylinder. The transfer cylinder is rotationally driven about its longitudinal axis and interacts with a folding cylinder having a set of folding jaws. The transfer cylinder has an external transfer surface interrupted by a number of sets of impaling pins and engaging blades intended to introduce the transversely cut web of paper into the folding jaws. The transfer cylinder also includes means for causing the angular spacing between the engaging blades and the impaling pins to vary. The disclosed transfer cylinder also includes, in the region of its external transfer surface, a set of closure plates on either side of each engaging blade and on either side of each set of impaling pins. The closure plates and the complementary plates may slide with respect to one another, so as to mutually overlap to form a practically continuous external transfer surface, regardless of the angular spacing between the engaging blades and the impaling pins.
