Patent ID: 8001757

Claim:
A double-twist bunching machine for fabricating bunched strand material having an inlet for individual strands which are supplied to a first deflection point that has a first deflection roller, the first deflection roller being arranged so as to be rotatable around an axis of rotation for forming a first twist, a bow rotating about the axis of rotation and connecting the first deflection point with a second deflection point, the second deflection point having at least one second deflection roller that is rotatable about the axis of rotation for forming a second twist, and a spool onto which the bunched strand material is wound and which is arranged outside the range of rotation of the bow, wherein the second deflection roller and at least one further deflection roller, which is assigned to the second deflection roller, form a deflection device mounted in pairs in a manner such that they can rotate about the axis of rotation, and wherein a supply point for the strand material is provided on the further deflection roller which lies between the second and the at least one further deflection rollers, and a pull-off point of the strand material is provided on the second deflection roller which lies in the second deflection point on the axis of rotation, and wherein the strand material after having passed the supply point of the further deflection roller twines itself and is supplied to the second deflection roller, the strand material crossing the supply direction to the supply point and twining itself subsequently around the second deflection roller, such that the strand material is guided out of the deflection device at the second deflection point.
