Definitions
- the invention relates to a heating device for heating a running thread in a texturing machine with the features according to the preamble of claim 1.
- Such heating devices are used in particular for crimping synthetic threads in a texturing machine through which the running thread is passed and crimped.
- the thread is guided in a heated groove, which is heated on its walls to a surface temperature that is above the melting temperature of the thread.
- several thread guides are provided in the heating groove, which guide the thread at a distance from the walls of the heating groove.
- the thread guides are attached to a carrier which is interchangeably arranged in the heating groove.
- Such a heating device is known for example from EP 0 731 197 (Bag. 2307).
- a heating device is known from DE 196 50 677 (Bag. 2358), which is used for heating a running thread sheet.
- the thread sheet is guided in a heating duct in a thread running plane parallel to the side walls of the heating duct.
- Such arrangements are unsuitable for use in texturing machines because of Loss of heat, in particular towards the edge of the thread sheet, does not allow uniform heat treatment to crimp the individual threads.
- the arrangement of the thread guides within the heating groove is selected such that a plurality of thread running tracks lying next to one another are formed for guiding several threads and that the threads are guided in a thread running plane spaced apart from the groove base.
- the particular advantage of the invention is that regardless of whether one or more threads are guided in the heating device, the threads are guided at substantially the same distance from the groove base.
- the thread running plane and the distance to the groove base is selected so that essentially the same heating times, heating intensities and friction act on each individual thread.
- the invention has the particular advantage that when a plurality of threads running in parallel are guided through a heating groove, each of the threads is exposed to an essentially identical ambient temperature. It is also possible to operate the heating device with one thread or with several threads.
- the thread running plane spanned by the thread guides, in which the threads are guided extends essentially parallel to the groove base.
- the threads are guided at a constant distance from the heating groove, so that a particularly uniform temperature effect on the threads is achieved.
- the heating groove which is closed by a cover during operation, results in a temperature gradient between the groove base and the cover side of the heating groove.
- the threads are guided within the groove at a height within the groove, so that temperature drops in the heating groove have no influence on the temperature of the threads.
- the thread guides are arranged in relation to one another in such a way that zigzag-shaped thread running tracks are formed, in which the threads are guided.
- the arrangement of a particularly preferred development of the invention leads to a very uniform treatment of the threads within the heating groove.
- the number and the arrangement of the thread guides are selected so that adjacent thread running tracks have a constant thread spacing between them in the longitudinal direction of the heater.
- the particularly advantageous embodiment of the invention according to claim 5 is preferably used in texturing machines in which two threads are brought together to form one thread before winding. With such a fold, different heat treatments of the individual threads are often desired, so that different designs of the thread running tracks can be achieved in a simple manner.
- the carrier is preferably made of a heat-conducting material.
- the thread guides are made of a ceramic or coated with a ceramic so that they have a high wear resistance. In particular, this has a long service life for the thread guides Episode.
- ceramics have the property that the tendency to accumulate inorganic constituents of the thread present in conventional steel thread guides is reduced and, in addition, the wear is less.
- the carrier consists of a good heat-conducting material and is designed as a profile rail with a plurality of guide grooves running in parallel.
- the outside profile walls of the profile rail are attached to the groove walls of the heating groove.
- the thread guides can be integrally formed in the profile rail.
- the thread guides are preferably formed with an L-shaped thread guide edge, so that the distances between the thread and the walls of the heating groove and between the thread and the groove base of the heating groove are determined by the thread guide edge. This is also a measure that leads to an equalization of the temperature treatment of the thread within the heating groove.
- the profile rail is formed by a plurality of U-shaped individual rails.
- the individual rails are connected on their opposite longitudinal sides, so that there is no heat blockage between the individual thread tracks.

- the heating groove 2 is limited by the walls 3, 4 and 5 in the radiator 1.
- the wall 5 represents the groove base.
- Below the groove base 5, the radiator 1 has two electrical heating elements 10.
- the radiator 1 consists of a very good heat-conducting material, so that the walls 3, 4 through the heating elements 10 and 5 of the heating groove 2 are heated.
- a carrier 11 is embedded in the heating groove 2 and lies essentially flush against the inner surface of the groove base 5.
- the carrier 11 has on the opposite side to the groove base 5 a plurality of thread guides 7 and 8 projecting into the heating groove 2.
- the thread guides 7 are arranged in two parallel rows at a distance in the longitudinal direction and form a thread track 6.1 between them.
- the thread guides 7 each have a thread guide edge 9 facing a running thread 19.
- the thread running track 6.1 is the guideway through which the thread 19 runs in the heating groove 2.
- the thread guides 7 are arranged with their thread guide edges 9 alternately opposite one another so that a zigzag-shaped thread running track 6.1 is formed.
- the thread guides 8 are arranged in two rows parallel to the thread guides 7 and form a thread running track 6.2.
- the thread guides 8 are also arranged with their thread guide edges 9 alternately opposite one another at a distance from one another, so that a zigzag-shaped thread running track 6.2 is formed.
- the thread running tracks 6.1 and 6.2 are formed with different numbers of thread guides 7 and 8.
- a plurality of thread guides 8 arranged one behind the other in short intervals are provided in the entrance area of the heater and no thread guides are provided in the central area.
- the thread running track 6.1 is formed by a number of thread guides 7, which are evenly spaced apart from one another.
- the thread guides 7 and 8 are shown in side view.
- the thread guides 7 and 8 each have an L-shaped thread guide edge 9.
- the L-shaped thread guide edge 9 provides a thread guide defined in its distances from the groove walls 3 and 4 and the groove base 5.
- a thread running plane 17 is spanned by the thread guide edges 9 of the thread guides 7 and 8 and is essentially parallel to the groove base 5.
- the threads 19.1 and 19.2 are thus guided through the heating groove 2 at one level.
- the thread guides are attached to the carrier 11 in a projecting manner.
- the thread guides are preferably made of a ceramic. However, it is also possible to use pin-shaped thread guides with a metallic surface.
- the arrangement of the thread guides 7 and 8 is selected in this embodiment such that different thread tracks 6.1 and 6.2 are formed in the heating groove.
- Such a heating device is preferably used for the heat treatment of threads, which are then brought together to form a thread and wound up.
- the arrangement of the thread guides 7 and 8 shown in FIGS. 3 and 4 is preferably used in the production of textured individual threads.
- FIGS. 3 and 4 show a further embodiment of the heating device according to the invention.

- FIG. 4 shows a cross section of the exemplary embodiment.
- the basic construction of the heating device is identical to the previously described exemplary embodiment, and reference is made in this respect to the preceding description.
- a profiled rail 14 is embedded in the heating groove 2 as a carrier.
- the profile rail 14 has two guide grooves 15 and 16 which extend in the longitudinal direction of the heater and are each delimited by profile walls 12 and 13.
- the profile rail 14 is also open to the open side of the heating groove 2.
- the profile walls 12 and 13 rest on the groove walls 3 and 4.
- the guide grooves 17 and 16 of the profile rail 14 are separated from one another by a central web 18.
- the thread guides 7 are arranged one behind the other in one plane in the longitudinal direction.
- the thread guide edges 9 of adjacent thread guides 7 are offset opposite one another arranged so that a zigzag-shaped thread running track 6.1 is formed in the guide groove 15.
- the thread guides 8 are arranged in a row offset from the thread guides 7. However, it is also possible to arrange the thread guides 8 symmetrically to the thread guide 7.
- the thread guides 8 are also arranged at a distance alternately with their thread guide edges 9 opposite one another in such a way that the thread running track 6.2 is zigzag-shaped.
- the thread guides 7 and 8 thus span a thread running plane 17 which is defined by the thread guide edges 9 of the thread guides 7 and 8.
- the thread running plane 17 is essentially parallel to the groove base 5.
- the surface of the thread guide facing the thread is rounded, so that the thread can gently sweep over the surfaces of the thread guide as it runs over the thread guide edge 9.
- the thread guide is L-shaped so that it has a boot shape.
- the boot shape of the thread guide 7 or 8 is formed by a shaft area and a tension area.
- the carrier 11 or the profiled rail 14 can be removed from the heating groove 2 in a simple manner, for example for the purpose of cleaning the thread guides, and can be used again after cleaning.
- the profiled rail 14 is made, for example, from one part. There is also the possibility of forming the profile rail 14 by means of two joined U-shaped individual rails. Each of the individual rails has a guide groove in which the thread guides are fastened. The individual rails are on their opposite long sides connected with each other. An illustration of this exemplary embodiment has been dispensed with, since the structure can be seen from FIGS. 3 and 4, the central web 18 being formed from the joined longitudinal sides of the individual rails.
- the radiator 1 When using such heating devices, the radiator 1 is surrounded by an insulating material. On the open side of the heating groove, a cover connected to the heating element 1 and the insulating material is provided, so that high heat loss is avoided. Because of the clarity, these components are not shown in the exemplary embodiments shown and are not described in detail.
- the arrangement of the thread guides and the formation of the thread running tracks in the exemplary embodiments described above are exemplary. In principle, any arrangement of the thread guides within the heating groove is possible in order to obtain symmetrical or asymmetrical thread running tracks.
- the number of thread running tracks is also not limited to two. In this way, more than two threads could also be passed through the heating groove side by side.
