ボビン交換の際に、供給される糸を案内しかつ切断する装置及び方法
Document Type and Number:
Japanese Patent JP4709391
Kind Code:
B2
Abstract:
An apparatus and method for guiding and cutting a continuously advancing yarn (1) during a package doff in a takeup device. The yarn is guided by means of a yarn guide (18) which is movable substantially parallel to a package or to a new tube (13), which is driven by a drive roll (29). Downstream of the yarn guide (18), a deflection device (2) and a suction device (37) are arranged, with the suction device comprising a pneumatic vacuum connection (46) and a cutter (47). The suction device (37) cooperates with a transfer device (42) 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 (18) is arranged in the path of the advancing yarn upstream of the driven tube (13), and a deflection device (2) as well as the suction device (37) are arranged downstream of the driven tube. For catching and winding initial layers on a new tube (13) that is driven by the drive roll (29), the yarn is guided by the deflection device (2) and the yarn guide (18) outside of the range of contact between the tube (13) and the drive roll (29).
