A foam-in-bag dispending system is featured with a dispenser with chemical
output port, a film feed assembly which feeds film to the dispenser for
receiving chemical output from the dispenser. The film feed assembly
includes a film drive roller set which includes a first roller and a
second roller rotating on non-coincident axes, an a support structure
which supports the film drive roller set. The support structure includes
a first frame structure and a second frame structure with the first frame
structure supporting the first roller and being adjustable relative to
the second frame structure so as to move said fist roller away from said
second roller. The present invention also features a method of servicing
a foam-in-bag dispenser system that includes moving a first frame
structure relative to a second frame structure between a closed position
to an open access position, with the first frame structure supporting a
component of a film feed assembly, and unlatching a latch assembly which
maintains the first and second frame structures in the closed mode and,
following unlatching, moving the first frame structure away from said
second frame structure to provide for easy servicing of, for example,
drive roller sets, heated wires (end and edge), film canes, pressing jaw
surfaces, as well as facilitated film feed.
