Abstract
A longitudinal sealer includes a housing, an arm, and a heating element. The housing is configured to be installed in a foam-in-bag system. The arm is movably coupled to the housing. The heating element has a leading edge exposed through an exterior surface of the arm. A position of the arm with respect to the housing is controllable so that the arm is movable between a first location where the leading edge of the heating element is not in contact with a film in a film path of the foam-in-bag system and a second location where the leading edge of the heating element is in contact with the film in the film path of the foam-in-bag system.
