Full Text | Spinning place of a spinning frame The invention relates to a spinning place of a spinning frame with a ring rail, a spinning ring and a ring rail tube. Such spinning places are for instance applied in ring spinning frames where a roving is drawn off the roving creel and is being drafted in a drafting unit. After the drafting unit the yarn, thread respectively is wound onto an empty tube, which rests on the spindle top of the spindle. Thereby said spindle top rotates at considerable speed together with the tube, whereat through winding of the yarn a cop is being formed. During the winding process the air surrounding the cop in the form of a relatively wide ring shaped cylindrical space has to be moved along. This, however, requires an increased power input of the spindle, the spindle top respectively during rotation around its length axis. Furthermore considerable dust develops in the range of the rotating cop, where larger portions of said dust consist of fibres, which issue from the yarn during winding. Therefore in this area special suction devices are being provided through which the fly dust is being sucked off. If a so called thread break occurs, then an unwinding takes place, caused by the centrifugal force of the thread towards the outside, whereat said thread parts can even enter the range of neighbouring spinning places and interfere with them. From JP-A-62-206037 a ring spinning place is known where a cop being formed is enclosed by telescope-type ring sections. Thereby, the spinning ring is mounted inside on a support ring, onto which the telescope tube is fastened underneath. This is very expensive, particularly because great accuracy is required for the defining of the telescope tube. It is the object of the present invention to improve such a spinning place in so far as the definition of a tube, a tube section respectively and also of the spinning ring are being simplified. To solve said task a support wall is furnished for the ring rail tube onto which the spinning ring is being mounted. According to the invention separate mounting of the spinning ring on the ring rail and thereafter mounting of the ring rail tube, the ring rail tube section respectively on the spinning ring or the ring rail does not anymore take place, but, all three elements are suited to each other in such a way that they complement each other with their way of mounting. In any case, provision is made to furnish the ring rail tube with an outer flange. Said outer flange has the function of connecting the ring rail tube with the ring rail. For simplicity reasons this connection is made by way of a screw, whereat said screw can either engage with a thread in the ring rail or through a hole in the ring rail together with a nut at its other end. Thereby the ring rail is provided'with the support wall onto which the spinning ring can be mounted, and which at the same time can easily be dismounted. This is for instance done by applying an O-ring being arranged between the ring rail and the support ring. It is also possible to use other resilient elements which allow for a plug-in type and centring connection. Further advantages, characteristics and details of the invention will become apparent from the following description 'of preferred exemplified embodiments and by means of the drawings; wherein shows Figure 1 a partial longitudinal cross section through a section of a spinning place; figure 2 a partial longitudinal cross section through a section out of a further exemplified embodiment of a spinning place. From this one spinning place, a ring spinning frame respectively a ring rail 1 is indicated, to which the ring rail tube 2 is to be connected. This ring rail tube 2 envelopes, at least partially, a not further shown cop being produced during the spinning process. For the connection of the ring rail tube 2 with the ring rail 1, the ring rail tube 2 is furnished with an outer flange 4 which rests on the ring rail 1. The ring rail 1 is furnished with a hole 5. This hole can be a threaded hole or an ordinary through hole, whereat a nut 7 is applied for mounting a screw 7 which is used as a clamping element. The ring rail tube 2, above its outer flange 4, has a support wall 11 formed to it, which is furnished with an outer ring groove 14. Said ring groove serves to hold an elastic 0-ring 15 which at the same time is held in* a further ring groove 16 of a spinning ring 3. With the help of said 0-ring the spinning ring 3 is mounted onto the support wall 11 in a way that it can also be easily dismounted from the support wall 11. In the exemplified embodiment according to figure 2, in place of a conventional spinning ring 3 a new type of spinning ring 3.1 is being provided, which furthermore is furnished with its own type of support ring 12 in extension of the support wall 11 in order to better guide a not further shown traveller. Support wall 11 and support ring 12 are preferably made in one piece.

A spinning frame with a ring rail (1), a spinning ring (3) and a ring rail tube (2), furnished with a support wall (11) onto which the spinning ring (3) is mounted, characterized in that the support wall (11) and the spinning ring each are provided with a ring groove (14, 16) facing each other in order to hold an O-ring (15). 2. The spinning frame as claimed in claim 1 wherein on the ring rail tube (2) an outer flange (4) is being provided, which, by fastening means (6), is connected with the ring rail (1). 3. The spinning frame as claimed in claim 2 wherein the outer flange (4) rests on the ring rail (1). 4. The spinning frame as claimed in claim 2 or 3 wherein the support wall (11), the outer flange (4) and the ring rail tube (2) are made of one piece. 5. A spinning frame substantially as herein described with reference to the accompanying drawings. Summary In a spinning place of a spinning frame with a ring rail (1), a spinning ring (3) and a ring rail tube (2) a support wall (11) is being furnished on the ring rail tube (2), onto which the spinning ring (3) is being mounted. |
