Abstract
A continuous web of paper is subdivided into a series of discrete webs of finite length, and successive discrete webs of the series are provided with looped sections in zig-zag formation. Successive discrete webs of the series are moved forwardly and away from the next-following webs of the series while advancing toward a stacking station to thus establish between successive discrete webs gaps of predetermined width. The making of gaps involves advancing the discrete webs with the upper reaches of three parallel foraminous endless belt conveyors which attract the webs and move them toward the stacking station. The median belt conveyor is accelerated when it is approached by the trailing end of a discrete web and then advances the trailing end at a speed exceeding the speed of the other conveyors and of the leader of the next-following discrete web. The median belt conveyor is thereupon disengaged from the accelerated discrete web and is decelerated so that it reassumes a predetermined starting position relative to the other belt conveyors.
