摘要

A device for producing cigarette filters which open with several groups of fiber opening roller pairs, which are provided along the transport route of a curled and transported Towstrreifens and the fibers of the Towstrreifens by giving it a clamping force in this transport direction, a pair of transport rollers, the lower side of the transport direction when the plurality of groups of fiber opening roller pairs is provided, rotates at a peripheral speed slower than the peripheral speed of the fiber opening roller pair furthest down from the plurality of fiber opening roller pairs, and transports the tow strip while weakening the tension force extending on the tow strip, a winding tube part passing further Underflow side of the transport direction is provided as the pair of transport rollers, forming the Towstreifen and transported the shaped tow strip to the lower side of the transport direction, un d is a control part which controls the respective peripheral speeds of the plurality of groups of fiber opening roller pairs and the pair of transport rollers, wherein the ratio WT2 / WT1 of a weight WT2 per unit length of the tow strip at the contact point of the transport direction furthest upstream fiber opening roller pair with the tow strip to a weight WT1 per unit length of the tow strip before crimping is assumed as residual crimping, and the control part based on the residual curl of the tow strip, the circumferential speed V0 of the transport direction furthest upstream side pair of fiber opening rollers and the transport speed of the formed tow strip from the winding tube part a tolerance value M1 of the speed ratio V2 / V0 the peripheral speed V2 to the peripheral speed V0 of the transport direction in the furthest downstream side Faseröffnungsrollenpaares determined, and the Geschwi ratio V2 / V0 so that it assumes the tolerance M1.
