Abstract: Exemplary embodiments of the present disclosure can provide a foam-in-bag device. The device can include a dispenser unit configured for dispensing a fluid foam-precursor into a web of film material for making foam-in-bag packaging material, a fluid supply conduit connected to the dispenser unit for delivering the foam-precursor to the dispenser unit, a valve connected to the dispenser outlet and that is actuatable between: an open condition allowing flow of the foam-precursor so as to permit the dispensing of the foam precursor, and a closed condition preventing flow of the-foam precursor so as to prevent the dispensing of the foam precursor. The device can further include a power-loss protection mechanism configured to direct auxiliary power to actuate the valve to the closed condition upon a loss of incoming power.

Abstract: Disclosed herein is a foam-in-bag dispensing system, including a dispensing apparatus operative to dispense foam precursor, the foam precursor being configured for expanding and solidifying into a polymeric foam, to a dispensing location between first and second web plies extending respectively on first and second sides of the dispensing apparatus; and a bag-status indicator associated for providing an indication to the operator indicative of the readiness of the bag for removal from the device for avoiding premature bag removal.

Abstract: Disclosed is a web handling system that includes a spindle having a spindle magnetic coupling portion and a roll core configured for receiving the spindle for mounting thereon and having a roll magnetic coupling portion, wherein the spindle and roll magnetic coupling portions are configured for magnetically attracting each other to hold the roll on the spindle.

Abstract: A sealer to bond film having a high temperature resistance (e.g., ceramic) substrate with properly sized groove receiving a heater element as in a flat faced wire band in a tight, flush to adjacent film presentation surface arrangement. A stacked ceramic plate set with wire band within a groove defined by an intermediate stack insert is a suitable substrate. The band is retained flush by a positioner securely locking down one end while the other end is provided at a housing body access location. The sealer is suited for use as a product-in-bag sealing device (products such as air, foam, foodstuff, etc.) with the heater element in contact with film to form a seal. A drag seal arrangement, where film layers are drawn past a fixed or adjustably mounted heater element is an example.

Abstract: 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.
