Embodiment Construction

[0025] figure 1 A side view is schematically shown of a station 2 of a textile machine for producing cross-wound bobbins, in this embodiment a so-called automatic cross-winder 1 . Cops 3 having relatively little thread material and produced on ring spinning machines are rewound at station 2 of an automatic cross-winding winder 1 of this type to form bulky cross-wound bobbins 5 . Once the cross-wound bobbin 5 is formed, it is transferred to the cross-wound bobbin transfer mechanism 7 along the machine length by means of an automatically operated service assembly (not shown, preferably a cross-wound bobbin doffing machine) and transferred to the Package loading station at the end of the machine, etc.

[0026] Automatic cross-winding winders 1 of this type usually also have a logistics system in the form of a bobbin or tube delivery system 6 . Cops 3 or empty bobbins rotate on the delivery disc 11 of the bobbin or tube delivery system 6 . For bobbins or pipe delivery systems 6...

Abstract

The present invention relates to a method for the production of conical cross-wound bobbins (5) with S-twisted yarn. According to the invention the S-twisted yarn as a sleeve (18) wound that forms a p-winding and symmetry ratio, i.e., the ratio of the laying speed between, as seen from the operating side, left and right front side of the cheese (5 ), is increased during the bobbin travel. The invention also relates to the cross-wound bobbin produced by the process (5) and the winding device (4) for carrying out the method.

Description

technical field [0001] The present invention relates to a method for producing conically cross-wound bobbins of S-twisted yarn. The invention also relates to a cross-wound bobbin and a winding device for producing the cross-wound bobbin. Background technique [0002] DE 10 2008 015 907 A1 discloses a station of a winding machine with a winding device for producing conically cross-wound bobbins. The product of the ring spinning machine, the bobbin, is rewound at the winder station to form bulky cross-wound bobbins. This type of cross-wound bobbin is usually designed as a conical cross-wound bobbin. In other words, the cross-wound bobbins have a smaller diameter when viewed towards one end face and have a larger diameter when viewed toward the other end face. In further processing, the cross-wound bobbins are drawn via the smaller diameter. This reduces the frictional force of the drawing at the yarn body of the cross-wound bobbin. [0003] The winding device has a creel,...
