APPARATUS FOR CONNECTING PAPER WEB WITH A PAPER WEB THREADING MEMBER

摘要

This invention has for its object to provide an apparatus for connecting a paper web with a paper web threading member wherein during the stand-by period of a retaining device the adhesive surface of an adhesive material in the retaining device is covered up by a movable cover so that paper dust or the like may be prevented from depositing thereon. The apparatus comprises a paper web retaining member connected to the upstream end of the paper web threading member and adapted to be located at a predetermined position along a paper web threading path where it is allowed to stand by; a retaining device for retaining a paper web, which has been advanced to the predetermined position along the path, onto the paper web retaining member through the intermediary of an adhesive material; and a movable cover provided in juxtaposition with the retaining device and adapted to be moved so as to selectively cover up or expose at least the adhesive surface of the adhesive material.
