ABSTRACT:
To permit easy threading of a plurality of paper webs through rollers which have projecting pins thereof to provide for positive feed of the paper webs by perforating the paper webs, the pins are located such that they can be selectively positioned below a cylindrical generated outline defined by the largest radial dimension of at least one of the engagement rollers, for example by being selectively retractable (FIG. 1) within the outline of the cylindrical roller, or by being located (FIG. 2) in flutes or depressions of fluted rollers. If the pins are selectively retractable and projectionable, preferably, a positioning cone (5) is located within a hollow roller (1), the axial position of the cone being determined by an external hand wheel (23) which, over a rod (4), axially positions the cone, while including a rotation-isolating coupling (14-22) between the hand wheel and the rod (4). The rollers may be located upstream, or downstream of the folding former, or in both positions, thereby functioning as supply or pull-off rollers, respectively.
