Abstract: A machine for forming molded foam cushions, including an apparatus for enclosing a foamable composition in a flexible bag; a mold having a cavity and a closure mechanism and being movable between an open position and a closed position such that, when in the closed position, the closure mechanism and the cavity define an enclosed three-dimensional shape, the mold comprising a material capable of transferring sufficient heat to or from the cavity to maintain the cavity at a desired temperature; a device for controlling the temperature of the mold cavity; means for placing the bag in the mold cavity while the mold is in the open position, whereby, when the mold assumes the closed position, the foamable composition expands within the cavity to form a foam cushion that substantially conforms to the three-dimensional shape; and means for pulling the foam cushion from the mold cavity.

Abstract: A packaging device is disclosed for forming packaging cushions of the type that include a plastic bag filled with a solid foam, and wherein the cushions are initially formed of a plastic bag filled with a foamable material that reacts and then hardens to form solid foam. The device comprises means for advancing a sheet of plastic film material that has been center-folded to form a doubled web with one closed edge defined by the center fold and one open edge defined by the adjacent edges of the sheet. Means are included for injecting a foamable composition into the center-folded web between the two folded portions of the sheet, as are means for forming a substantially linear seal along the open edge and substantially parallel to the open edge to thereby longitudinally seal the open edge of the web.

Abstract: A roll support system for supporting a roll of web material is provided which includes a mechanism for retaining and easily releasing a roll of web material wound around a core and having a telescoping core plug adapted to snugly fit in each end of the core. A core plug is provided with a telescoping spindle biased toward its extended position to support a roll in the support mechanism.
