FORMER FOR FOLDING DEVICE

摘要

PURPOSE:To provide the former of a folding device capable of preventing the pollution and unstable travel of a web sheet and reducing the friction resistance against the traveling web sheet. CONSTITUTION:The web sheet W passing through the peripheral face of a drug roller 1 is traveled on the guide face gradually narrowed in width and the guide face of a side edge guide section 5, of the main guide section 4 of the former 3 of a folding device, both side edges are folded and guided along the longitudinal direction by the guide face of the side edge guide section 5 and gradually folded into two, and the web sheet W is nipped by nipping rollers 2 in the two-folded state and guided to a cutting barrel. The web sheet W is brought into contact with rotors 6 rotated by the traveling web sheet W at least on the side edge guide face, and the friction between the web sheet W and the former 3 is made rolling friction and sharply reduced.
