Definitions
- the invention relates to a thread storage and
- the thread should pass through the device on its thread path
- Components of the device come into contact several times, some of the components of the device rotating relative to the running thread, the thread
- the quality of a thread storage and delivery device is in fact judged by the reliability, ie the frequency of the thread breaks during operation, because everyone
- Thread breaks occur predominantly between the feed area and the storage element of the thread storage and delivery device, i.e. where, as a rule, a deflection of the thread occurs, coupled with friction, so that the assumption is obvious that between the frequency of the thread breaks and the thread guide surfaces and the action of the thread breaks.
- Thread guide surfaces on the thread there is a connection Thread guide surfaces on the thread there is a connection.
- the invention has for its object a
- Thread guide surface containing thread guide surface in a very specific way, namely according to an isostatic
- the hard materials of the element group Si, B, Ti, Zr, Hf, V, Nb, Ta, Cr, Mo, W (silicon, boron, titanium, zirconium, hafnium, vanadium, niobium, tantalum, chromium, molybdenum, tungsten) , in particular of silicon and / or boron, can be in
- Si ntermateri al achieve the sliding properties so favorable for the different threads, whereby the small grain sizes (around 1 micron) possible with these fabrics also make an probably important contribution.
- the isostatic hot press sintering in a capsule shell prevents foreign or mechanical or
- Sintered material with one of the specified hard materials, e.g. Silicon nitride, as the main component, is used in various fields of technology; however, the use and selection of this extremely expensive sintered material generally involves high mechanical loads in combination with strong thermal ones
- this sintered material is used in a high density setting
- the embodiment of claim 2 is advantageous. With such a large deflection angle, a significant contact pressure of the thread is also to be expected, which plays a role in the extent of the load in the thread. The low friction of the thread occurs in such guide surfaces
- Silicon nitride has proven to be a particularly useful hard material. Small additions of boron nitride and / or carbide are advantageous. Yttrium oxide as Additive allows a high density and good adhesion of the components to be achieved.
- the frequency of the thread breaks is already determined by the use of the high-density ceramic sintered material for the guide surfaces with a large, e.g. reduced deflection angle of the thread by more than 90 °; however, since the other guide surfaces in the thread path can also be the cause of thread breaks, it is expedient, according to claims 7 and 8, to use several or all of the guide surfaces made of the high-density sintered material, e.g. with silicon nitride as the main component, because the
- the use of the isostatic hot pressing process leads, particularly in the preferred embodiment according to claim 10, to low surface friction.
- Trigger area of the device is used, goes from the
- the device can also be a zone that is critical with regard to yarn breaks, especially if guide surfaces with extremely favorable sliding properties are already present upstream and downstream. It is therefore advantageous to use the high-density ceramic sintered material with the specified values in this area too
- Hard materials e.g. with silicon nitride, as
- FIGS Claims 13 and 14 in which the storage member is arranged stationary and the winding member one of a hollow, connected to a rotary drive
- Main shaft protrudes radially outward beyond the storage area of the adjacent storage organ
- Pipe socket is in the free end of the
- the thread has the same, favorable sliding conditions throughout the groove. Even in the event of unavoidable spinning movements of the thread during its run, it essentially always touches the guide surface over the same length. There are no sharp edges or protrusions at which local strain on the thread could occur.
- the thread also finds optimal sliding conditions when it runs up or down the guide surface. The loads exerted to deflect the thread are distributed evenly over the effective length of the guide surface and remain as a result of the low friction, in particular when using silicon nitride
- the embodiment according to claim 16 is also important because the funnel-shaped trough allows the thread to move laterally without it coming into contact with rubbing edges and because the same thread guide can be used for both directions of rotation of the winding member.
- the embodiment according to claim 17 is structurally simple and easy to assemble.
- the cylindrical outer section serves to fix the thread guide body.
- the inner thread guide surface with the collar is responsible for the gentle treatment of the thread, the thread never coming into contact with the component of the device on which the
- Thread guide is set.
- the high abrasion resistance and high mechanical strength are welcome in the sintered material, as this means that the thread guiding surfaces even after a long time
- Thread guide body can be designed to be delicate and therefore easy, which - if they move - is too small

- Thread guide body 10 and the storage surface 2 represent a particularly critical area in that thread breaks occur here more than with the thread guide surfaces L of the thread guide bodies 8 and 13. This is due to the large deflection angle (180 ° -ß, 180 ° - ⁇ , and against Winding direction) and the associated frictional forces between the thread and the thread guide surfaces L.
- the thread guide surface L in the thread guide body 12 consists of a high-density ceramic sintered material with one or more carbide, nitride or carbonide nitride hard materials of the element group: Si, B, Ti, Zr, Hf, V , Nb, Ta, Cr, Mo, W, as

- the thread is deflected on its path and also rubs against the other thread guide surfaces, it is expedient if the other thread guide surfaces, at least those with a significant deflection angle, are made of the same high-density sintered material, for example with Silicon nitride as the main component. This also applies to the pull-off edge 4 of the storage element S, where a coating or an insert ring 16 made of high-density sintered material is applied in order to form the thread guide surface L over which the thread is pulled off and

- Boron carbide or yttrium oxide gave a value of 1.64. This means an improvement of around 12.7%.
- Sintered material for the same thread gave a value of 1.98. This means an improvement of around 10.4%.
- Cotton thread of a common thread count has a value of 2.04, while with the same thread on the same guide surface made of high-density sintered material with the
- testing was carried out with a thread length of 2 x 20 cm at a load of approx. 30 cN, both the thread guide and the thread used for the test being cleaned with alcohol after each test run.
- a PES thread ie a polyester or nylon thread, and a cotton thread were used for the test, each with a first Speed of 100 mm / min. and then at a second speed of 1000 mm / min. was pulled over the thread guide surface under load.
- Thread guiding surfaces which consist of conventional sintered material. This gentle treatment of the thread results in a decrease in thread breaks, which was previously the case predominantly occurred in the area of the thread path in which the strongest deflection and therefore the greatest mechanical stress was present for the thread. This applies to all thread counts and thread qualities on such thread feeders and feeders
- the mechanical abrasion resistance of the high-density sintered material with silicon nitride as the main component ensures a long service life without any noticeable
- Sintered material is the contribution of the thread guiding surfaces to the smallest and most uniform possible
- Thread take-up tension as it is cheap for modern textile machines.
