该装置由两个旋转驱动盘（26Ú27），辊或被布置为彼此这种类似的旋转体，要么两个盘的两个端面（26Ú。27）或盘（27）和所述外表面的端面 形成辊隙的相互下摩擦接触的辊，通过该被扭转的纱线（14）与两个面向的摩擦表面传递，使得它是假捻。 在每一个实施例中，两个旋转体中的至少一个是其与按压装置（6）在其一侧从线端面相关联的远程的柔性盘（27）。 按压装置（6）局部地按压柔性盘（27），以便它是（27）只在对螺纹（14）的辊隙的面积朝向隆起并且所述旋转体（26Ú27）之间被夹紧。 柔性盘（27）是薄壁的并且由具有低电阻的材料的弯曲，但高的拉伸强度。 第二旋转体（26,27）可以是刚性的形成圆盘（26），辊或第二柔性光盘。 在后者的情况下，盘与另外的压力装置（6）相关联。

The device consists of two rotationally driven disks (26 u. 27), rolls or similar rotating bodies which are disposed to one another that either two end faces of the two discs (26 u. 27) or an end surface of a disc (27) and the outer surface a roll forming a nip with each other, through which the to be twisted yarn (14) under frictional contact passes with two friction surfaces facing one another, so that it is false twisted. In each embodiment, at least one of the two rotating bodies, a flexible disk (27) associated with a pressing device (6) on its end face remote from the yarn. The pressing (6) presses the flexible disc (27) locally so that it is (27) bulged only in the area of ​​the nip line against the thread (14) back and this between the rotating bodies (26 u. 27) is clamped. The flexible disk (27) is thin-walled and consists of a material with a low resistance against bending, but with a high tensile strength. The second rotating body (26, 27) may be a rigidly formed disc (26), a roller or a second flexible disc. In the latter case, the disc is associated with a further pressure device (6).
