    Abstract: A process for the production of sheeting from chips of a thermoplastic material includes the steps of forming a granulated thermoplastic synthetic polymeric material transversely and longitudinally into a crude sheet, cutting the crude sheet into transverse strips, and cutting the transverse strips longitudinally into chips having approximately rectangular configurations. Thereafter the process further includes stacking the chips in a uniform distribution in a thin layer, heating the stacked chips to sinter the layer of stacked chips into a sheet, winding the sheet into a round multilayered block, radially compressing the multilayered block, cooling the compressed block and peripherally paring the compressed block into sheeting.

    Abstract translation: 一种用于由热塑性材料的碎片生产热塑性板的方法，该方法包括以下步骤：将粒状合成聚合物热塑性材料压延成至少一个粗片，将粗片切割成横向条，将横向条纵向切割成碎片，每个 具有大致矩形的构造，将芯片以均匀分布堆叠到所需粗糙块的水平面，加热堆叠的芯片，然后将堆叠细分成所需粗糙块的尺寸。 此后，将粗块放在模具中，在其中被加热压缩并随后冷却，然后分成板。

    Abstract: AN APPARATUS FOR PRODUCING A WOUND PIPE OF THERMOPLASTIC SYNTHETIC RESIN, WHEREIN A PROFILED BAND OF THERMOPLASTIC, HAVING ONE EDGE PROVIDED WITH A TONGUE AND THE /OTHER EDGE THEREOF PROVIDED WITH A BEAD CONTAINING A GROOVE FOR RECEIVING SAID TONGUE, IS WOUND SPIRALLY IN THE SOFTENED CONDITION ABOUT A ROTATING MANDREL WHEREBY THE TONNGUE OF A PRECEDING WINDING LAP IS CONTTINUOUSLY RECEIVED IN THE GROOVE OF THE BEAD OF THE IMMEDIATELY SUBSEQUENT WINDING LAP, COMPRISING A ROTATABLE DRUM MEANS, AT LEAST ONE PRESSURE ROLL ASSOCIATED WITH SAID DRUM MEANS AND A MEANS, PREFERABLY A SERIES OF TAKE-OFF ROLLS, FOR REMOVING THE FINISHED PIPE FROM THE DRUM MEANS, THE PRESSURE ROLL COMPRISES THREE SECTIONAL ROLLS HAVING A CONTOUR WHICH CORRESPONDS TO THE JUNCTION POINT BETWEEN SUCCESSIVE WINDINGS OF THERMOPLASTIC, THE THREE SECTIONAL ROLLS SUBSTANTIALLY COVERING THE JUNCTION POINT. USING THIS DEVICE, A UNIFORM CONTACT PRESSURE AND, THUS, A UNIFORM AND SATISFACTORY WELDING BOND IS ONTAINED BETWEEN THE TONGUE AND GROOVE THERMOPLASTIC WINDINGS.
