Abstract
Abstract To provide for threading of paper webs to a folding apparatus (140), a plurality of paper webs (1-8; 77-84) are fed from respectively opposite sides to a plurality of deflection rollers directing the paper webs in a vertical combining plane (9). The deflection rollers are positioned in vertically staggered arrangement. The paper webs are positively fed by transport rollers (26-29; 53-56) or transport belts (110-113; 128-130), located on respective carrier plates (18, 19; 93, 94) which are movable towards or away from the combining plane and on which the transport rollers or belts are located, staggered, between the deflection rollers on the same side and so as to engage the deflection rollers on the other side of the combining plane, to provide for positive drive of paper webs and feeding to the folding apparatus (140) during threading, or upon tearing of a web, but permitting withdrawal laterally upon full-speed operation of the paper handling apparatus, for example the folder. Additional transport belts (69, 70; 138, 139), also movable on carriers towards and away from the combining plane, can be provided to transport the combined superposed webs, likewise movable out of engagement with respect to each other, that is, away from the combining plane, after threading has been completed.
