ABSTRACT A continuous winder which produces individual rolls of sheet material having a high quality finish. This is accomplished by maintaining a surface-winding layon roller in contact with each roll throughout the entire winding operation. The winder is comprised of a support frame having a turret mounted therein which carries a plurality of spindles onto which the individual rolls are wound. A double layon roller assembly is mounted in the frame so that one of the layon rollers is in contact with a first spindle during the winding operation. A length counter generates a signal which starts the transfer operation when a roll is wound whereupon a second spindle is brought up to speed and a cutter is extended adjacent the sheer of the material. Simultaneously, an auxillary layon roller is moved into contact with the second spindle. Adhesive on the second spindle pulls the web onto the cutter starts the winding on the second spindle. The cutter is retracted, and the turret is indexed approximately 30°. The auxillary layon roller remains in contact with the second spindle during this indexing while the primary layon roller remains in contact with the first spindle. When the primary layon roller clears the finished roll, the second primary layon roller moves into contact with the second spindle. The auxillary layon roller is retracted and the turret is indexed approximately an additional 60° to move the second spindle to the normal roll buildup position.
