Abstract (en)
[origin: EP2325356A1] The present invention provides a technique for further stabilizing an unwinding point relative to a belt crossing portion, while simultaneously making a device compact. A belt type false twist device 111 nips and twists yarn Y by allowing a reference belt 1 and a movable belt 2 to travel so as to cross and compressively contact each other. A driving pulley 10 around which the reference belt 1 is wound includes an untwisting disk 50 with an outer peripheral edge 50a. The untwisting disk 50 is configured to rotate together with the driving pulley 10. The outer diameter D of the untwisting disk 50 at the outer peripheral edge 50a thereof is set to be equal to or larger than a value obtained by adding the thickness of the reference belt 1 to the outer diameter of the driving pulley 10. A part of the yarn path of the yarn Y located downstream of a crossing portion R is bent by the contact of the yarn Y with the outer peripheral edge 50a of the untwisting disk 50.
