Abstract: A torn paper web capture system that is a mechanism for securing a band, tape or strap, preferably composed of paper, across a paper roll as the roll is rotating. A sensor means detects the torn paper web and initiates both the shut down of rotation of the paper roll and the release of the band. The band resides within a guide track, the track being generally C-shaped in cross-section Upon contact with spool journal or similar rotating member the end of the band adheres and is wrapped around the rotating member. This wrapping action takes up the slack in the band and pulls it from the guide track and against the paper web, thereby securing the loose end of the paper web. The contact between the band and the rotating member may be initiated in multiple ways, such as with a nip roller, an actuating shoe member, or the like.
