- From DE 196 26 549 A1 is also in a generic device an envelope or a housing shown that is narrow in relation to the coil Distance and fixed is arranged and at least the lateral surface of the Completely surrounds the coil.
- the housing is made according to a special advantageous embodiment of two jacket parts, the up and together are pivotally connected.
- the operation of such a device is due to the split jacket particularly advantageous because the coil leaking thread is easily accessible by opening the jacket and can be exchanged for a full spool.
- the one from the spool pulled thread forms a balloon.
- This thread balloon is through the pot limited.
- the pot wears out especially at high speeds modern winding spinning machines.
- Existing pots are either closed costly to manufacture or not sufficiently wear-resistant, so that in some cases they have to be replaced after a short period of operation.
- the object is achieved by a device with the features of Claim 1.
- the friction of the winding thread, which on the pot when Pulling off the spool can be done by pulling on the respective Application mechanically and / or thermally wear-resistant Layer must be coordinated.
- the pot that acts as a balloon limiter for the thread creates with the mechanically and / or thermally wear-resistant layer optimal. Friction conditions for the thread.
- the duration of use of the pot is also particularly advantageous also an even higher rotational speed of the winding spindles possible because of the risk of thread breakage due to a corresponding adapted layer can be significantly reduced.
- the layer works over it energy saving in a particularly advantageous manner compared to conventional pots because of the friction with the thread are optimized.

- the pot insert is advantageously easy to replace. You can therefore against Pot insert with a different type of layer for other applications to be replaced.
- the pot consists of a basic body and at least partially the Coil surrounding mechanically and / or thermally wear-resistant layer, so it is advantageously possible to optimally move a pot towards that processing yarn in terms of its mechanical and / or thermal Customize and use properties. It only has to mechanically and / or thermally wear-resistant layer on the appropriate winding thread can be set to optimal Obtain wear results.
- the base body of the pot can each be maintained. This makes it both an inexpensive manufacturable as well as in particular optimally designed pot for created various uses.
- the basic body with its Fastening devices on the winding spinning device can in each case to be kept.
- the pot consists essentially of the material of the mechanical and / or thermally wear-resistant and / or low-friction layer, so is created a particularly simple embodiment of the invention. At a Wear or damage to the layer will then damage the entire pot replaced. On the other hand, the production of the pot, in particular if it is made of a material that is easy to machine, such as stainless steel is made, relatively inexpensive.
- the layer is at least partially arranged on the inner circumference of the pot, this enables the pot to be produced cost-effectively.
- the layer which can be very costly is made advantageous by this Design limited to the zones within the pot in which they can bring their properties to full effect. This is particularly true of the Places where the thread balloon is limited by the pot and thus the Thread in contact with the pot. It can therefore also be advantageous if the layer at least only partially in the axial direction on the inside of the Pot is arranged.
- the Transition zones of the individual pot halves are particularly susceptible to wear and therefore require special wear protection at these points.
- the layer is arranged at least in the region of the inner circumference of the pot, in which the withdrawn yarn is in contact with the pot or the layer.
- the pot is mechanically and / or thermally stressed, which makes it it is advantageous if these points with the layer or with the corresponding coated or made entirely of the wear-resistant material Pot insert is provided.
- the base body consists of plastic.
- the basic body of the pot is simple and inexpensive to manufacture. Particularly high demands on one Wear resistance should not be placed on the base body, since it is on the crucial points is provided with a pot insert according to the invention.

- the aluminum or plastic layers described bring for individual use cases, especially for the Processing certain threads also has advantages.
- the layer is made of chrome, nickel or ceramic, then one is special high wear protection guaranteed.
- Novel, mechanically and / or thermally wear-resistant plastics can also advantageously as Pot insert or used as materials stored in the pot insert become.
- the base body can be made from one its mechanical and / or thermal properties simple plastic be made while the stressed parts from the high quality Plastic.
- the layer is structured.
- an orange peel or a wavy, embossed, structured or blasted surface depending on the used Wrapping thread and production speed are an advantage.
- the surface the layer is polished.
- the surface is brush polished, brush polished and wobbled or chemically polished.
- the layer according to the invention is a thin application on a surface, it is advantageous if the surface of the pot insert is coated with this layer. It can vary in individual .Application also offer a plasma coating.
- the thin layer of the pot inlay is made of chrome, nickel or ceramic, then the pot insert itself from a less mechanical and / or thermal wearable material and the required properties are taken from the chrome, nickel or ceramic of the layer.
- the pot insert is also in a particularly advantageous manner as an adapter for different coil diameters can be used.
- the pot insert has different coil diameters usable that the distance of the inner circumference of the pot regardless of the coil diameter used is essentially constant. So is with smaller coil diameters a thicker pot insert can be selected, while at larger spool diameters a thinner pot insert can be used.
- the distance between the inside of the pot insert and the spool or the spool plate is to keep it essentially constant, thereby narrowing the Thread balloons is influenced in an advantageous manner. higher Withdrawal speeds are possible.
- the pot insert is designed such that it The interior of the pot is shortened in the axial direction. It is an extreme variable use of the present invention possible.
- Pot inserts can thus be used which are in the axial direction or in act in the radial direction of the pot.
- To those for the axial shortening of the Pot's pot insert is a different requirement than the one Part of the radial cup insert. Therefore, it can be advantageous if the part for axial shortening of the pot has different material properties than that part of the pot insert acting in the radial direction.
- the axial part of the Pot insert does not have to be designed to be wear-resistant, so that it is simple here Materials can be used.
- the direction of air flow in the pot essentially predict. It is therefore particularly advantageous if the pot insert is shaped so that it affects the air flow in the pot. In particular a conical design of the pot insert has been found to be advantageous proved. By arranging the taper at certain points of the Pot insert it is even possible to change the air flow in different axial To cause directions of the pot.
- the inlay of the spool, especially its spool plate should be tight enclose. All that is required is a gap through which the Thread can be removed during operation. Through this narrow gap the friction of the thread on the pot is particularly high and the invention particularly effective.
