Problems solved by technology

In addition, there is the problem that the moment at which the fiber sliver is cut is uncertain, so that the fiber sliver may be cut off before its new reel is fixed and wound up and has the consequence of interrupting the process.
This problem arises especially during the winding of filaments or slivers at relatively low speeds

Embodiment Construction

[0026] figure 1 and 2 An embodiment of a winding device according to the invention is shown in several views. figure 1 The front view shows the embodiment and figure 2 This embodiment is shown in plan view. The following description applies to both figures, as long as there is nothing more particularly emphasized about one of the figures.

[0027] This exemplary embodiment of the winding device has a bobbin turret 2 which is rotatably mounted in a machine frame wall 1 and which can be rotated counterclockwise via a turret drive. The bobbin turret has two rotatably mounted bobbin spindles 3.1 and 3.2, which are each held with a free end projecting. The bobbin spindles 3.1 and 3.2 are held on the bobbin turret 2 offset from one another by 180°. Each bobbin spindle 3.1 and 3.2 is connected in a drive device such as figure 2 As shown in , each can be formed by a spindle drive 19.1 and 19.2.

[0028] The bobbin spindles 3.1 and 3.2 each have a bobbin 5.1 and 5.2, around wh...

Abstract

The invention relates to a winding device for continuously winding a fiber strand. The winding device has a rotatably supported winding revolver (2) having two rotationally drivable winding spindles (3.1, 3.2), which are retained on the winding revolver in a protruding manner and which each have a winding sleeve (5.1, 5.2) and a catching apparatus (4.1, 4.2) On the winding revolver (2), two severing apparatuses (7.1, 7.2) are associated with the winding spindles (3.1, 3.2). The severing apparatuses cause the fiber strand to be severed when the fiber strand is transferred from one of the winding spindles having a wound full spool to other winding spindles. A traversing apparatus (8) is arranged upstream of the winding spindles and has a traversing thread guide (9), which can be moved parallel to the winding spindles and which can be positioned outside of a traversing stroke in order to transfer the fiber strand. In order to obtain defined severing of the fiber strand at relatively slow process speeds, each severing apparatus (4.1, 4.2) has a blade (27) and a locking means (26) associated with the blade, wherein the fiber strand (42) is guided by the blocking means (26) before the severing and wherein the fiber strand (42) causes a release of the locking means (26) when a minimum tensile force is reached and can be fed to the blade (27).

Description

technical field [0001] The invention relates to a winding device according to the preamble of claim 1 for the continuous winding of threads or fiber strips. Background technique [0002] A winding device of this type is known, for example, from EP 0 450 085 A1. [0003] Threads or fiber strips or other continuous strands which are supplied continuously, for example produced during a production process, are usually wound into rolls for storage. An automated winding device is preferably used for this purpose, so that a plurality of bobbins can be wound continuously without noticeable interruptions as much as possible. Such an automated winding device has at least two bobbin spindles which alternately wind the thread or fiber strand to form a package. Basically, the individual winding spindles can be held on movable spindle supports or fixedly on a stationary spindle support. In both variants of the spindle support it is necessary that after completion of a package on one of...
