Abstract

La masse de polymère, qui contient des plastifiants et éventuellement d'autres additifs, est transformée en une feuille épaisse sur une calandre en-dessous de la plage de fusion, étirée puis chauffée rapidement à la température thermoplastique, l'étirage éventuel de la feuille pouvant se faire au plus tot en meme temps que le chauffage. L'invention trouve son application particulière dans la fabrication de feuilles plastiques transparentes et présentant une excellente qualité de surface.The mass of polymer, which contains plasticizers and possibly other additives, is transformed into a thick sheet on a calender below the melting range, stretched and then quickly heated to thermoplastic temperature, the possible stretching of the sheet. can be done as soon as possible at the same time as heating. The invention finds its particular application in the manufacture of transparent plastic sheets and having an excellent surface quality.
