Abstract: A process for the production of thermoplastic plates from chips of a thermoplastic material which includes the steps of calendering a granulated synthetic polymeric thermoplastic material into at least one crude sheet, cuttting the crude sheet into transverse strips, cutting the transverse strips longitudinally into chips, each having an approximately rectangular configuration, stacking the chips in a uniform distribution up to the level of the desired rough block, heating the stacked chips and then subdividing the stack into the dimensions of the rough block desired. Thereafter, the rough block is placed in a mold where it is compressed with heating and subsequently cooled and then divided into plates.
