Abstract
An apparatus for applying a tubular band from a supply of flat tubular material to a container includes a flat film feed path and a cutter positioned for cutting tubular material traveling along the feed path. A former is positioned downstream of the cutter for opening the tubular material and includes a film passage with an inlet side and an outlet side. The flat film feed path enters the film passage and a cut segment of tubular material is opened within the film passage to create an opened tubular band. A pusher pushes the opened tubular band out of the outlet side of the former for container application. The pusher includes a film engaging portion that is aligned with and movable into and out of the film passage. The film engaging portion is offset from the flat film feed path to prevent interference with flat tubular film entering the passage.
