Abstract

A method of making hot-deformed objects of large dimensions e.g. sections of hoppers or temporary buildings is as follows: a thermoplastics sheet is clamped into a folding frame, then the frame is folded to the desired shape, and the warmed sheet is thus shaped without reducing is thickness.
