Abstract
To permit web portions (16, 17; 18, 19; 20, 21) slit from longitudinal webs (2a, 2b, 2c) to be selectively interleaved or interlaced, with or without turning over, pairs of turning bars or rods (6, 7; 8, 9; 10, 11; 12, 13) are located in essentially vertically aligned position; laterally of the turning rods, two deflection rollers (22, 23) are positioned which can be individually movably shifted by individual drive motors (32) operating a gear on a rack formed on guide rails, so that the deflection rollers can be selectively positioned at the level of a selected pair of turning rods. This permits placement of a web portion, right side up or turned over, between a pair of web portions which is not necessarily the next adjacent one in the vertical sequence of superimposed webs arriving at the interlacing or interleaving system.
