Embodiment Construction

[0014] 1-3 only show a creel arm 1 of a creel generally known, for example, from DE2711024C2, on which a hollow shaft 2 is mounted. A centering disk 4 is supported on the hollow shaft 2 by means of a bearing 3 and has at least one suction channel 4.1 extending radially inwards from its outer peripheral surface. Each suction channel opens into the hollow shaft 2 . Mounted on the centering disk 4 is a bobbin 5 which can be driven by means of a friction drive roller 6 which can be driven in the direction of the arrow f1. The friction drive roller 6 is provided with a traverse guide 7 capable of moving back and forth in the direction of the double arrow f2. FIG. 1 also shows a feed roll 8 and a conventional overfeed roll 9 .

[0015] The hollow shaft 2 opens into a cylindrical housing 10 which is substantially open on its outer end face.

[0016] A suction head A is arranged next to the creel arm 1 . The suction head A has a housing 11 with an annular chamber 11.1 open towards...

Abstract

An apparatus for winding a cross-wound bobbin onto a bobbin tube is provided and comprises a bobbin creel including two bobbin creel arms for the mounting of two bobbin tube centering plates, a thread intake device effective in the region of an arm and with which is associated a thread severing device, a drive unit for a bobbin shaft / cross-wound bobbin, and a traversing thread guide adapted to be driven to move back and forth along the bobbin shaft / cross-wound bobbin. A given bobbin creel arm is provided with at least one intake or suction channel that is directed radially inwardly from the periphery of the centering plate and that opens into a hollow shaft guided outwardly through an associated arm. A suction head is adapted to be placed against the hollow shaft and is provided with a thread clamping mechanism and the thread severing device.

Description

technical field [0001] The invention relates to a winding device according to the preamble of claim 1 . Such a winding device is described in DE2711024C2. Background technique [0002] In textile machines, such as spinning machines and twisting machines, the yarn is continuously supplied to a winder located at each spinning position and there it is usually wound into cross-wound bobbins. For the continuous processing of cross-wound bobbins to be pieced in the form of a veil (Faden reserve) and to smoothly doff the cross-wound bobbin to the last turn, the faden reserve consists of a yarn that has The same spinning or twisting twist as the yarn as a whole is wound into a cross-wound bobbin. [0003] A further requirement was that the winding of the yarn on the empty bobbins and the formation of the veil should be done as automatically as possible in order to reduce the burden on the workers on the one hand and to achieve a constant and reproducible winding process for the co...
