ABSTRACT:
The instant invention is directed to a novel process and apparatus for the production of rebonded foam, and particularly polyurethane foam scrap. The process and apparatus allow for the simultaneous performance of three and preferably four basic operations, i.e. mold filling, curing or steaming, boring and mold stripping, to achieve the shortest, most efficient time cycles to produce a high quality rebonded product. Significant improvements are seen in the quality of the product, reduction in density, reduction in scrap loss, elimination of density variations in the molded product and overall product consistency.
