Abstract
A dual-belt system for solidifying products such as hot-melt resins by passing a product layer through a treatment zone formed by two endless steel belts. The product layer is precooled so that the product strip has substantially the desired cross-sectional shape prior to entering the treatment zone. During the precooling step the product spreads by the action of gravity, and the rates of precooling and movement are such as to insure that the product strip has dimensions within acceptable tolerances.
