Abstract
Process for obtaining hollow objects starting from a plate of thermoplastic material, which is essentially characterized in that the parts of the plate that have to be configured by stretching in depth, are first subjected to a temperature close to the softening point of the plate, and in that, during the course of stretching, the configuration is completed during the working process, the stretched portions reach regions where they can cool down again below their softening point.
