Master processing apparatus with master engaging structure for tensioning a master

摘要

A multi-purpose laminating and adhesive transfer apparatus having a frame supporting rotatably engaging nip rollers. A replaceable cartridge is insertable into the frame and has upper and lower feed rolls which may be a laminate, film or paper, or an adhesively coated film or a film having an affinity for adhesive. The upper and lower feed rolls containing the webs of laminating or adhesive transfer material have tensioning caps which can be adjusted to provide the proper tensioning to prevent the rollers from overrunning as they rotate. Tensioning caps and the cartridges are pre-set and provided to the user. A cutter blade is positioned at the discharge side of the nip rollers and may be actuated to sever the master at any desired location. The apparatus may be operated to apply lamination to either top or bottom surfaces of a substrate or an adhesive to the top or bottom surface of the substrate or to both surfaces.
