METHOD AND APPARATUS FOR MAKING FOAM-IN-PLACE CUSHIONS WITH SELECTIVE DISTRIBUTION OF FOAM |
摘要 |
A method and apparatus for making a foam-in-place cushion in which a foam-forming composition is dispensed between two plastic film portions in a predetermined fashion to selectively control the distribution of the foam in the cushion. A foam dispenser can be moved in a transverse direction as foam is dispensed. A dispersion device can be employed to apply pressure on predetermined areas of the film portions towards each other so as to cause the composition to be redistributed in position in a predetermined manner while the composition is in a less than fully expanded state. The plastic film can then be sealed closed to form an expanding foam cushion that can be placed into a shipping carton where the cushion expands to fill void space, or into a mold where the cushion expands and is molded into a desired shape.
