Abstract (en)
[origin: EP0305305A1] Device making it possible to impart a false twist by friction to a fibrous material. <??>It comprises two endless belts (1, 2) inclined relative to one another and mounted on two pairs of rollers (3, 4, 5, 6). <??>According to the invention, the supporting rollers (3, 4, 5, 6) which support the two belts (1, 2) are mounted on the actual housing (8) of the spindle by means of two supporting arms (9, 10, 11, 12), one of the supporting arms (10, 12) of each pair being subjected to the action of pressure means making it possible to ensure the tension of each belt (1, 2), and at least one of the other two supporting arms (9, 11) being mounted in an articulated manner on the housing (8), and there is no need to maintain parallelism between the axes of said rollers. <IMAGE>
