Abstract
An apparatus and method for guiding and cutting a continuously advancing yarn ( ) during a package doff in a takeup device. The yarn is guided by means of a yarn guide ( ) which is movable substantially parallel to a package or to a new tube ( ), which is driven by a drive roll ( ). Downstream of the yarn guide ( ), a deflection device ( ) and a suction device ( ) are arranged, with the suction device comprising a pneumatic vacuum connection ( ) and a cutter ( ). The suction device ( ) cooperates with a transfer device ( ) for purposes of cutting the yarn during a package doff and receiving the loose end of the advancing yarn. To enable a gentle processing of the yarn during the package doff, the yarn guide ( ) is arranged in the path of the advancing yarn upstream of the driven tube ( ), and a deflection device ( ) as well as the suction device ( ) are arranged downstream of the driven tube. For catching and winding initial layers on a new tube ( ) that is driven by the drive roll ( ), the yarn is guided by the deflection device ( ) and the yarn guide ( ) outside of the range of contact between the tube ( ) and the drive roll ( ).
