ABSTRACT:
To prevent buckling of a lowermost one, or a lower group of superposed webs being fed, in superposed relation to a common folding triangle or folding former (1), a driven supply roller (2) is provided which has its circumference formed with projecting pins (6) or the like, long enough to penetrate through the entire stack of the superposed web (8) as it runs over the supply roller, thereby feeding all the webs at the same speed to the folding former. Preferably, a hold-down roller (9) is provided, formed with a circumferential groove (10) aligned with the pins (6) so that the pins can penetrate through the webs and fit into the groove (10).
