Slitter-rewinder system

Abstract

A system and method for slitting and rewinding includes a slitter and a drum type rewinder. A core cutter includes a magazine for retaining a plurality of cores and a programmable transversely movable core slitter which may be moved to discrete transverse locations for severing a selected core into widths corresponding to the setting of the slitter knives. A core transporter receives the sections of slit core and transports the same to the winder drums while, at the same time, moves the completed roll out of winding position. A web severing and adhesive applying apparatus cuts the web from the winder and applies strips of adhesive to the tail and lead edges of the back. The core sections as formed by the core slitting or sectioning apparatus, are maintained in predetermined alignment according to the position of the knives and are inserted into the winder by the transporter behind the previously formed roll as the roll is moved out of the winder, resulting in a minimum of lost time or wasted material. The system is capable of fully automatic operation without the necessity of core handling, slitting, core placement, or web attachment thereto by an operator.
