Abstract

A stretching unit comprising a plastic panel between upper and lower tool platens is heated in a heating station(126) until the softened plastic adheres to the tool platens. The assembly is then fed to a stretching station(130) where the platens are parted slightly to increase the panel thickness. After stretching the cellular panel is cooled to allow removal from the platens. An Independent claim is made for the process equipment which includes lower and upper platens, heating (126), stretching (130) and cooling (134) stations and a conveying system (122,124) for moving a stretching assembly between the heating, stretching and cooling stations.
