Abstract (en)
[origin: DE19814921A1] The invention relates to a frictional twisting device for texturing synthetic filament yarns, comprising several adjacent, parallel, rotating shafts with at least one friction disk disposed on each shaft. The friction disks are offset against each other and are axially arranged on the shafts at a mutual distance, whereby the intersecting circumferential arcs of said disks, when seen from an axial overhead position, form a common overlap area in which an overlapping circle tangent to the inside of the circumferential arc can be placed, whereby the thread running through the frictional twisting device forms a type of helix with an angle of inclination alpha ranging from 38 DEG to 41 DEG . The invention also relates to a method for determining the individual parameters of the frictional twisting device.
