Abstract (en)
[origin: EP0054652A1] 1. Apparatus for performing a method of making an elastic twist, in which an elastomer thread of about 145 dtex to 310 dtex is adhesively twisted with two yarns having a thickness of 100 to 12 500 dtex consisting of polyvinyl chloride, polyvinyl cyanide, polyacrylonitrile and/or wool threads, the surface of the yarns being swollen at a pressure of between approximately 0.1 and 0.2 bar in hot steam at a temperature of about 70 degrees C for up to 10 minutes, in order to loosen them and obtain the adhesion, the elastomer thread being given a draft with respect to the yarns during the twisting operation, characterised in that the draft of the elastomer thread (10) is produced before twisting by sliding friction on at least one friction surface (20), the sliding friction force being controllably variable per unit of time by a control device (16).
