Title: FILM INFLATION SYSTEMS AND COMPONENTS THEREOF
Abstract:
A nozzle is usable to inflate a film having two sides that form a common channel and inflatable channels. The inflatable channels are in fluid communication with the common channel. The nozzle includes a proximal end configured to separate the two sides of the film to open the common channel as the film moves in a longitudinal direction. The nozzle includes a distal end configured to permit the two sides of the film to converge as the film moves in the longitudinal direction. The nozzle includes a slot configured to direct gas transversely into the common channel to inflate the inflatable channels as the film moves in the longitudinal direction.
