Method for operating a spinning device

Abstract

The invention relates to a method for operating a spinning device, comprising a centrifugal spinning element, which rotates at a high rotational speed, and a thread guide tube, which projects into the centrifugal spinning element and which is provided with a re-reeling sleeve that is displaceably mounted thereon. The thread guide tube executes, relative to the centrifugal spinning element, a traversing travel and a superimposed forward movement and places a yarn package with a cop winding onto the inner wall of the centrifugal spinning element. The invention provides that, at the end of the regular spinning process as well as in the event of thread breakage during the spinning process, a drive of the thread guide tube is controlled in such a manner that: the last traversing movement of the thread guide tube runs upward to a re-reeling position that is specified by the lowermost dead center of the traversing travel; the re-reeling sleeve on the thread guide tube is subsequently lowered by defined distance; a re-reeling process is initiated, and; after completion of the re-reeling process, the thread guide tube is driven into a lower stop whereby the resulting spinning cop is transferred into a defined doffing position.

Description

technical field [0001] The invention relates to a method for operating a spinning device. Background technique [0002] In centrifugal spinning, the feed material, such as the fiber sliver stored in the can or the roving placed on the roving bobbin, is first drafted to the required count by means of the drafting device, and then the The yarn guide tube feeds them into a centrifugal spinning element that rotates at high speed. In this case, the drafted feed material coming out of the yarn guide nozzle, forming the yarn foot, rests on the inner wall of the centrifugal spinning element and is carried along by it. That is, the fibrous material is twisted by the rotation of the spinning element, resulting in the formation of a yarn. The yarn formed as a result of twisting is stacked during the spinning process via axially displaceable yarn guide tubes on the inner wall of the centrifugal spinning element and forms there a yarn package, which is also called For yarn cake.

Problems solved by technology

Although such a roving reel is advantageous due to its structure, that is, it is always accessible after a package interruption in the rewinding process or after an interruption of the yarn in the spinning process, the produced bobbins usually impose a burden on subsequent processes. Difficult, since the subsequent automatic winder for cross-winding bobbins is in principle designed for processing ring-spun bobbins
