A film supply apparatus supplying film in a foam-in-bag system having a film feeding device for feeding film from a film source to a location for bag formation, a bag forming apparatus, a foam material dispenser positioned for feeding foam material for reception in a bag of the bag forming apparatus, and a web tensioning system with a web tensioning driver in driving communication with the film source and which is in communication with a controller for monitoring the film feed and web tension states and directing adjustments in the web tension system. The web tensioning driver is arranged to move film backwards or in a direction opposite to a direction of film feed induced by the film feeding means and with the film source including a roll of film and the web tensioning system including a drive transmission in communication with the roll of film for rotational driving of the roll of film and also in communication with web tensioning driver. There is further featured a spindle support for supporting the roll of film and a roll film core drive insert.

Film unwind system with hinged spindle and electronic control of web tension

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.

An end sealer shifting assembly, comprising a transmission, a push rod assembly which is driven by the transmission, and end seal compression jaw in driving engagement with the push rod assembly, and a compliance assembly for jaw compliance with a contact member (e.g., a heater wire cutter cross cut jaw) when the jaw is driven into a compression relationship with the contact member. The compliance device preferably includes springs and the transmission assembly preferably includes a cam device with a second spring working to retain a contact relationship and work together with the compliance spring. A method of assembling such a device and operating such a device is also featured.
