DESCRIPTION: A vertical structure mounting a dancer assembly to provide line speed control, a bubble rotator to provide a push button means of orienting film printed in the layflat for post-print gusseting, a roller collapsing frame, gusset boards, bottom nip drive rolls, and two air driven winders.

The printed film enters the POST GUSSETER through the DANCER ASSEMBLY, through the BUBBLE ROTATOR, and downward through the collapsing frames and gusset boards and through the bottom nip rolls of the POST GUSSETER. From the discharge of the nip rolls, the film may be wound on the dual spindle winder or fed to a bag machine or sheet winder. The film tube is inflated at the discharge of the BUBBLE ROTATOR. The inflation air is trapped between the discharge nip rolls of the BUBBLE ROTATOR and the bottom nip rolls of the POST GUSSETER. The width of active air vents is easily adjusted by a screw at the end of the turning bar.

The turning bar and the nip rolls are mounted on separate frames carried on a rotating hub that is mounted to a crossmember at the top of the post-gusseter tower.

The film is printed in the layflat, fed into the POST GUSSETER over the turning bar, through the nip roll assembly, re-inflated, and fed through the gusseter.

The printing is oriented by changing the turning bar and nip roll angles to the incoming and outgoing film.
