Abstract

Inventia se refera la un procedeu conform caruia un fir natural înfasoara doua suprafete cilindrice de presare si trece sub forma unor spire peste si sub o suprafata cilincdrica de distantare si una de etirare cu axele paralele între ele. Suprafetele cilindrice de presare si de etirare se rotesc în jurul axelor lor, cu o viteza constanta si mai mare la ultimul. Suprafata cilindrica de distantare este dispusa rotativ sub actiunea frecarii firului si frînata periodic dupa un program predeterminat. Se aplica în industria textila.The invention relates to a process according to which a natural yarn draws two cylindrical pressing surfaces and passes in the form of turns over and under a cylindrical distal surface and an erect one with the parallel axes between them. Cylindrical pressing and tipping surfaces rotate around their axes at a constant and higher speed at the last. The cylindrical spacing surface is rotatably disposed under the action of thread rubbing and periodically braked after a predetermined program. Applies to the textile industry.
