An apparatus for ganging and cutting a plurality of layers of strip material in predetermined lengths includes a frame supporting a drive and driven roller acting together to draw the layers of material to a cutter where the layers of material are severed. The drive roller, acting with the driven roller, draws a plurality of layers of material from a rack structure where each layer is individually wound on a rotatable roll. Each layer of strip material is drawn from a roll and a plurality of layers are ganged over a cylindrical roller. The ganged layers of material are directed over a convex-concave roller combination to maintain alignment. The layers of material are then drawn over an upper support roller and are guided to the drive roller through a guide plate structure. The guide plate structure includes a back plate having a slot therein and a top plate having a longitudinal shoulder corresponding to the slot. The layers of material are maintained within the slot of the back plate to prevent lateral movement by the layers of material. The layers of material are engaged between the drive and driven rollers and directed to a severing station where the layers of strip material are cut into predetermined lengths. Structure for tensioning each layer of strip material is provided.
