Embodiment Construction

[0031] Figure 1A , 1B schematically represent a centrifugal spinning device generally indicated by reference numeral 1 in a partial cutaway front view. Such a centrifugal spinning device 1 has long been known in relation to centrifugal spinning machines and has been described in considerable detail, for example, in WO 98 / 11284.

[0032] As shown in the figures, such centrifugal spinning devices 1 each have a centrifugal spinning element 3, which is rotatably mounted in a spinning hood 2 via a magnetic bearing 4 during spinning and passes through An independent electromagnetic drive mechanism 5 is driven and rotates at a high rotational speed. Here, for economical reasons, the separate electromagnetic drive 5 of the centrifugal spinning element 3 is usually arranged in a neck-shaped constriction.

[0033] The centrifugal spinning device 1 also has a drafting device 6 for drafting the feed material 18, a sensor 13 which can be connected to a workstation computer 19 by means of...

Abstract

The invention relates to a centrifugal spinning device comprising: a spinning pot that is mounted inside a bearing housing while being able to rotate about a central axis; a thread guide tube that can be displaced parallel to the central axis of the spinning pot by means of a drive, which can be driven in a defined manner, and; a re-reeling sleeve that is displaceably mounted on the thread guide tube. The invention provides that: a thrust piston gearing (10) can be traversed jointly with the thread guide tube (7); the thrust piston gearing (10) comprises a piston (11), which can be displaced relative to the thread guide tube (7), comprises a through boring (36) and which has a connected hollow piston rod (12); the thread guide tube (7) is guided through the piston (11) and the hollow piston rod (12), and; a guiding and stopping bush (31) that fixes the re-reeling sleeve (9) is connected to the piston rod (12) of the thrust piston gearing (10).

Description

Background technique [0001] Various methods are disclosed regarding the production of staple fiber yarns. [0002] Apart from ring spinning and rotor spinning, for example centrifugal spinning is a spinning method which has been known for a long time. Here, centrifugal spinning is in principle divided into two different spinning types, so-called single-stage spinning and so-called two-stage spinning. [0003] In both spinning types, firstly, a feed material, ie either fiber sliver stored in cans or roving supplied in the form of bobbins, is drawn at a draft suitable for the desired yarn count. The yarn is drafted in the device and fed into a centrifugal spinning element rotating at a high rotational speed via an axially displaceably supported yarn guide tube. The feed material coming out of the yarn guide nozzle, forming the yarn foot, rests on the inner wall of the centrifugal part and is carried along by the inner wall of the centrifugal part. This means that the fiber ma...
