Abstract: Wind-on device for workstations of two-for-one twisters and ply twisters with 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, and a driven advance roller positioned upstream of the friction roller in the yarn run. According to the invention, 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 can be pivoted together with the support element (23, 24) about a pivot axle selectively into an operating position or into a higher situated service position.

Abstract: The present invention provides yarn winder that can provide a vibration suppressing function for the yarn winder over a long period despite minor differences in vibration characteristic among individual yarn winders. A vibration suppressing device is provided in a yarn winder comprising rotatable bobbin holders 105 and 106 supported on a body frame 102, the bobbin holders each having bobbins installed thereon and around which packages P are formed. The vibration suppressing device comprises an impact damper 10 comprising a mass body 11 and a regulation member 13 for holding the mass body 11 in such a manner as to have degrees of freedom. The impact damper 10 is provided in a site that vibrates as the bobbin holders 105 and 106 rotate, for example, at a tip of an elevating bracket 109.

Abstract: In a bobbin winding machine with multiple winding heads, each having a creel associated with a torque transmitter (15) adjusted by a drive element (16) for controlling the bearing load between a bobbin (10) held in the creel and a drive drum (14), buttons (18, 19) are provided for actuation by an operator for adjusting the drive element (16) and therewith the creel (12) for adaptation to a diameter of a residual bobbin to be inserted into the creel (12).

Abstract: A winder for elastomeric fibers, which can reciprocate the fiber during winding and provides a substantially constant distance of fiber travel between the point where the fiber leaves the puller roll and the point where the fiber first contacts the contact roll, is provided.

Abstract: An apparatus and a method for guiding and cutting a continuously advancing yarn during a package doff in a takeup device. In this connection, a movable yarn guide guides the yarn substantially parallel to a package or a winding tube, which is driven by a drive roll. The yarn guide is followed by a suction device, which consists of a pneumatic suction inlet end and a cutting device. The suction device cooperates with a transfer device for purposes of cutting the yarn during the package doff and receiving the loose end of the advancing yarn. To protect the yarn during the package doff, the yarn guide extends in the yarn path upstream of the driven tube, and the suction device downstream thereof.
