Patent ID: 7866589

Claim:
Wind-on device for workstations of a two-for-one twister machine or a ply twister machine comprising a take-up bobbin, a drive shaft extending in the longitudinal direction of the machine, a friction roller which is driven by the drive shaft and causes the take-up bobbin to make a rotational movement for winding of a traveling yarn thereon, a traversing yarn displacement device for delivering the yarn traversingly to the take-up bobbin to wind thereon in a cross-winding manner, and a driven advance roller positioned upstream of the friction roller relative to a path of yarn travel onto the take-up bobbin for looping of the traveling yarn about the advance roller for reducing tension in the yarn prior to winding on the take-up bobbin, characterised in that in addition to the friction roller ( 14 , 15 ), the advance roller ( 8 , 9 ) is also driven by the drive shaft ( 27 , 28 ) and in that the advance roller ( 8 , 9 ) is mounted on a support element ( 23 , 24 ) and pivots together with the support element ( 23 , 24 ) about a pivot axle selectively into an operating position or into a higher situated service position.
