ABSTRACT:
A web of a paper or board manufacturing machine is severed utilizing a severing tape in a fully automatic operation. A main (Pope) cylinder and reel drum are part of a winder for the web, and have a nip therebetween, the cylinder and drum mounted for rotation about parallel axes. A severing tape is attached by adhesive tape to a cardboard card mounted by a pivotal arm on a first side of the winder, with an intermediate portion of the tape held outwardly from the arm by a tape dispenser with spring clip. On the second side of the winder a swing guide is mounted for pivotal movement about an axis perpendicular to the main cylinder, and mounts a spool of tape for rotation about an axis parallel to the main cylinder. The card is inserted in the nip when web severing is desired, tape is taken up on the reel drum, and after the tape is tensioned and severs the web the tape is cut by a pair of cutting blades mounted at the second side of the winder. The operation may then be repeated for another web after attaching the severed end of the tape to another card.
