Abstract

Relief parts the formed on a sheet by (a) heating a part of the sheet corresponding with the relief, while maintaining the parts of the sheet outside this area at a low temp. and (b) drawing out the heated part in order to deform it, the stiffness of the cold part preventing its deformation. Used for prodn. of articles such as covers, containers and cups from sheets of thermoplastic material. The cold part of the sheet retains its original flat shape and is not deformed. Printed parts thus remain intact.
