MACHINE AND METHOD FOR FORMING MOLDED FOAM CUSHIONS

摘要

A machine for forming molded foam cushions (48), including an apparatus for enclosing a foamable composition in a flexible bag (16); a mold (40) 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 (14) 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.
