Abstract
A system for detecting and registering serrated bags includes a web including a plurality of bags connected in an end-to-end arrangement, each bag including a first and second side, a first and second longitudinal end, a transverse seal, a serration disposed transversely across the bag, and a tab integrally connected to the bag at a portion of but less than the entire extent of the tab; a device for projecting a stream of air on each bag as the web passes a predetermined location; and a first and a second pair of nip rolls, each disposed downstream of the device, and adapted to accommodate the web, and to drive at different speeds such that a lead bag is separated from the web.
