Description

Thread processing system and yarn feeding device

The invention relates to a yarn processing system according to the preamble of patent claim 1 and a yarn feeding device according to the preamble of claim 17.

In a yarn processing system, which includes, inter alia, a textile machine such as a knitting machine or a loom and this functionally assigned Fa¬ denliefergeräte, the yarn feeding devices are fixed to the storage body hanging down on a support device. The support device has a clamping profile which has either square or round cross-section. Especially in the case of a circular knitting machine whose knitting systems many yarn feeding devices must be zuge¬ assigned that optimal thread geometries can be achieved, the support device may be a support ring from the clamping profile with round or square Quer¬ cut. Similarly, the carrying device of the yarn feeding devices for a weaving machine, a so-called state, has at least one clamping profile with a round or square cross section. Conventionally, the fixations of the yarn feeding devices are adapted to the cross section of the clamping profile of the respective carrying device, that is, there are yarn feeding devices with a fixation only for square cross sections, and Fadenlieferge¬ devices with a fixation only for round cross sections.

From the technical information sheet 11.905.001.01 DANC-25 from the company Memberger-Lro GmbH, D-72277 Dornstetten "Storage Feeder NOVAKNIT 1000" is a Fixie¬ tion on the underside of the housing of the yarn feeding device known, with a downwardly open neckline with square cross section for receiving a square clamping profile has. The fixation is rotatable about a relative to the longitudinal axis of the clamping profile in an approximately vertical axis relative to the housing of the yarn feeding device.

From the technical information sheet "Yarn Storage Feeder SFE" of Memminger-lro GmbH it is known to integrate the fixation in the back of the housing of the yarn feeding device. The fixation has a downwardly open cutout with a square cross-section for receiving a square edged square clamping profile. On the yarn feeder facing broad side of the square clamping profile a ribbon cable is installed, which extends into the cutout and is connected there with placed in the cut Kontaktierungsgliedem. The fi x tion allows only 90 ° offset mounting positions of the yarn feeding device.

It is known from the technical information sheet "Halter" 006.900.018 of 02.05.2001 of the company Memminger-Iro GmbH to equip yarn feeding devices of the EFS type with one of three different fixings, depending on the cross section of the clamping profile of the carrying device. The first type is used for attaching the yarn feeding device to a clamping profile with a round cross section. The fixation is rotatable about a relative to the core line of the clamping profile vertical axis relative to the housing of the yarn feeding device. Furthermore, the yarn feeding device can be rotated with the fixation around the round clamping profile and clamped in different rotational positions. The section of the fixation has a curve corresponding to the curvature of the clamping profile. The second type comprises a fixable with respect to the housing of the yarn feeding device fixation with a cutout, which is open and square in the direction of the housing wall carrying the fixation away. Thus, the yarn feeding device can be set approximately parallel to the vertical axis of the square cross section. The third type comprises a fixation which can be rotated relative to the housing, the four-edged cutout of which is open at the side. In the cutout, a recess for inserting a flat cable is provided opposite the clamping element. In the opening contactors are placed stationary. The flat cable installed on the square clamping profile on its broad side is inserted into the recess and applied to the contacting members by the contact pressure of the clamping profile. Only 90 ° offset mounting positions are possible.

The invention has the object of providing a thread-processing system and a yarn feeding device in such a way that one and the same fixation of the Fadenlieferge¬ device regardless of whether it is useful whether the clamping profile has a round cross section or a square cross section. Here, the task is to be solved to be able to connect a case-by-case installed flat cable regardless of whether the clamping profile has a square or a circular cross-section. Finally, the yarn feeding device should be uni¬ versally adjustable on the clamping profile with regard to an optimal yarn geometry. The stated object is achieved with the features of claim 1 and claim 17.

Since the cutout can optionally be applied to a square or a circular cross section of the clamping profile, a clamping profile-independent universally mon¬ Tierbares yarn feeding device is created.

Thanks to the special configuration of the cutout, the yarn feeding device can be mounted on either a square or a round cross-section clamping profile of the carrying device in an uni versally manner. This structural design of the fixation not only increases the availability of the user of yarn feeding devices, but also offers production technology and logistical advantages as a clamp-independent universal yarn feeding device by the manufacturer. Here, the neckline is either convertible or formed from the outset suitable for both types of cross-sections.

If, in a preferred embodiment, the cutout of the fixation can optionally be changed in order to fit a round cross section or a square cross section of the clamping profile, one and the same Fadenlie¬ fergerät can also be used for supporting devices in thread-processing systems, the clamping profile of a round cross-section or a Square cross section has. This is particularly advantageous for the user because he does not have to worry about the gripping profile of the optionally present carrying device when purchasing the yarn feeding devices, or about the procurement of a carrying device with regard to the cross section of the clamping profile does not need to be oriented to the fixations existing or future to be procured yarn feeding devices.

In an expedient embodiment, the cutout of the fixing is designed with a square configuration, and at least one adapter part which can be inserted into the cutout with the square configuration is provided for conversion into the round configuration. Depending on the cross section of the clamping profile, the adapter part is inserted or omitted. It goes without saying that the concept should also be reversed, ie that the cutout is formed with a round configuration, and least one adaptable to convert to the square configuration adapter part is hen vorgese¬. The respective adapter part is a simple, inexpensive and small accessory part of the yarn feeding device.

Suitably, the adapter part has a round depression with a curvature of the circular cross-section of the clamping profile at least largely corresponding radius of curvature. The depression can be semicircular and is possibly structured in order to achieve a firm frictional engagement or even a positive fit. The recess may be formed in radians smaller than 180 ° or even larger than 180 °, in the latter case, if necessary, for achieving a snap-on holder on the clamping profile.

In an alternative embodiment, the adapter part has a V-shaped recess. At least one V-flank may have texturing or grading to increase frictional engagement. The V-shaped cross-section fits round cross-sections of different diameters, which enhances the universal usability of the fixation. The steps may even fit different square sections.

In order to achieve a tight fit of the yarn feeding device on the respective clamping profile, it is advantageous if the cut is bounded by at least one free-ending, the clamping element containing leg, and if in the neck opposite the leg a support is provided against the means of the clamping element either the clamping profile or the adapter part can be pressed. The support may in this case be flat for pressing the square clamping profile or a flat side of the adapter part for the circular cross section, or the support may be gerun¬ det for applying the Rundklemmprofils or a correspondingly round side of the adapter part for a square cross section. Suitably, the Ausspa¬ tion opens laterally, i. approximately in the direction in which the adjacent housing side of the yarn feeding device runs. However, it is quite possible to arrange the open side of the cutout from the side of the housing of the yarn feeding device leading the way.

With regard to the simple connection of the yarn feeding device to a flat cable, it is expedient in one embodiment if a flat cable Recess is provided, are placed in the contacting members, and a flat cable installed along the clamping profile inserted into the recess and is brought by the contact pressure of either the clamping profile or the adapter part against the support with the Kontaktierungsgliedem in contact. This connection method for the flat cable can be realized with the fixing regardless of whether the flat cable with square or a round clamping profile is installed.

Since it is possible in practice that, e.g. In the direction of the adjustability of the clamping element, the strength of the round cross section is significantly greater than the thickness of the square cross section of the clamping profile, it may be advantageous, in one embodiment, to adjust the distance of the leg of the fixing relative to the support , If the fixation is to be fastened to a thin clamping profile with a square cross-section, the distance of the leg from the support can be shortened beforehand. Conversely, the distance of the leg is increased for a strong square or round clamping profile.

In terms of manufacturing technology, the adapter part is a plastic molded part, e.g. a plastic injection molded part.

Because of the simplicity of the adapter part, e.g. For selectively producing the circular configuration of the cutout, the adapter part can assume an additional function when installing the flat cable on the clamping profile. This means that the adapter is fixed to the clamping profile like a retaining clip and in turn supports the flat cable. This additional function of the adapter can be used where without this the yarn feeding device is fixed with the fixation on the clamping profile. According to a further aspect, a plurality of such adapter parts can in principle also be snapped onto the clamping profile as fastening clips for the flat cable, where no yarn feeding device is positioned.

It is expedient if the round depression of the adapter part extends over more than 180 ° in the radian measure, in order to obtain a snap-on effect with the elasticity of the adapter part, for example made of plastic, and on which Recess side facing away from the adapter part to arrange a positioning device for the flat cable, for example in the form of slightly flexible hook or the like.

In order to expand the adjustment range of the yarn feeding device relative to the clamping profile, it is particularly expedient according to a further aspect to arrange the fixation on the housing of the yarn feeding device in a rotationally adjustable manner at least approximately perpendicular to the core axis of the clamping profile. The fixation in different rotational positions should be able to be fixed relative to the housing.

In order to enable an adjustment of the yarn feeding device to the clamping profile core axis even with a square clamping profile, even a kind of ball joint zwi¬ tween the housing and the fixing may be appropriate. This adjustment could also be achieved by two adapter parts in the neck, of which one can rotate relative to the other and the square clamping profile.

Suitably, the respective adjustment range is limited in order to prevent damage in the electrical connection between the contacting members and electrical components inside or outside the yarn feeding device.

Because of the adjustment, it is expedient in another embodiment to place the contacting in the fixation stationary and to connect via flexible conductor with a stationary in the housing of the yarn feeding device Stromschnitt¬ point. These flexible conductors should be laid with a certain excess length and optionally freely, so that they allow the relative adjustment between the housing and the fixation.

Regardless of whether the clamping profile has a square cross-section or a circular cross-section, use the yarn feeding device without switching the fixation and without holding ready parts or need to remove parts inserted, set and position, a further embodiment of the yarn feeding device is characterized by a in the neck the clamping plate ausgebil¬ Deten clamping member movably arranged pressing plate, in which the Fadenlie¬ fergerät pointing bottom is provided an approximately V-shaped recess. The press plate transmits the holding force of the clamping element on the clamping profile, regardless of whether the clamping profile has a square cross-section or a Rund¬ cross-section. On the square cross-section, the press plate with two contact areas flat, while a circular cross-section is set in two contact areas in the recess. The recess may be formed, for example, V-shaped and sharp-edged, or slightly rounded in the deepest region or at the ends of the flanks, or ribs if necessary.

Suitably, between the press plate and the clamping screw a formschlüssi¬ ge coupling is provided which captively couples the press plate in the axial direction of the clamping screw with the clamping screw, however, allows relative rotational movements zwi¬ tween the clamping screw and the press plate. As a result, the clamping screw can be rotated in the threaded bore of the leg relative to the pressing plate and may adjust the pressure plate relative to the fixation optionally on the course of the clamping profile.

Advantageously, the pressure plate on the clamping screw is at least limited tilted and held captive. The tilting mobility allows at least limited Kippla¬ gene settings of the yarn feeding device relative to the clamping profile and allows proper adjustment of the press plate to the clamping profile to exert a high clamping force evenly.

In terms of manufacturing technology, the press plate is a sheet-metal bent part with an approximately constant wall thickness. The V-shaped recess is bent in the optionally flat pressure plate so that it extends continuously over the length of the pressure plate.

In an advantageous embodiment, the pressing plate is rectangular or square and longer in the transverse direction of the cutout than this, preferably in such a way that the pressing plate protrudes from the cutout on both transverse sides of the cutout. In this way, the holding force is exerted over a large area on the clamping profile. The recess is expediently generally V-shaped and formed continuously over the length of the press plate, so that it also interacts with a large area over a large area.

With regard to perfect power transmission conditions, the V-shaped recess should be at least approximately symmetrical to the axis of the clamping screw and have an opening angle greater than 90 °, preferably an opening angle of approximately 120 °. With this design, the fixation can be reliably attached to round sections unter¬ different diameters.

In a further advantageous embodiment, a pressing surface adjoins each side edge of the V-shaped depression, wherein the two pressing surfaces should lie in a common plane which is substantially perpendicular to the axis of the clamping screw. Preferably, these pressing surfaces are bounded by mutually parallel and optionally straight edges which border the edge strips of the pressing plate. The pressing surfaces come in a square profile of the clamping profile to the plant, while they may have no function in a circular cross section.

Another important aspect is different width pressing surfaces to bei¬ the sides of the V-shaped recess. The press plate can be placed in the cutout after dismantling the clamping element in two installation positions rotated by 180 ° about the axis of the clamping screw. In the one installation position, a predetermined larger tipping position setting gap is formed between the edge of the narrower edge strip and the wall of the cutout, while in the other installation position there is only one minimum or no guide gap. In one installation position, the fixing with the yarn delivery device can thus be swiveled around the axis of the clamping element at least to a limited extent, so that mounting positions of the yarn feeding device are possible for optimal yarn geometry or from others In the other mounting position, however, the press plate can not, or hardly twist relative to the fixation, which may be advantageous in a clamping profile with square cross-section. If the press plate in a square clamping profile in one Placed installation position, then at least a limited rotation of the yarn feeding device relative to the clamping profile is possible about the axis of the clamping element.

In an expedient embodiment, the cutout is bounded by a limb, on which at least one support plate is displaceably guided. The Aufla¬ geplatte may be about as large as the press plate or larger or longer. The support plate is supported on the bearing surface on the yarn feeding device or secures the flat cable in the depression, while the contact force on the support of the yarn feeding device on both the square and cross-section is transmitted. The support plate is also useful in a round cross-clamping profile to avoid that the round cross-section deforms the flat cable inappropriate. In the case of a square clamping profile, the supporting plate could be removed or omitted, in which case the square clamping profile lies directly on the support of the yarn feeding device.

In a particularly advantageous embodiment, the support plate is guided in a dovetail guide on the leg. This dovetail guide can be formed directly between the side edges of the leg and the platen, or at undercut guide edges of the leg. The support plate is therefore initially captive part of the fixation and can still be adjusted along the leg, for example, to insert the flat cable in the recess before the fixation is finally determined on the clamping profile.

In an expedient embodiment, the limb is releasably fixed to the yarn delivery device, preferably in several different fixing positions. As a result, the effective length of the fixation can be adapted to the thickness of the clamping profile, and the leg can be dismantled, for example, to remove the support plate, if he wishes to decrease.

With regard to an optimal thread geometry, a position of the yarn feeding device rotated about the core axis of the clamping profile may be desirable, for example downwards about the axis of the yarn feeding device in the carrying device to align diagonally to the center of the knitting machine. On a clamping profile with a round cross-section, the tilting position can be freely selected, thanks to the round cross-section anyway. In a square clamping profile such a tilting position is not readily possible, but only thanks to the wedge cross section of the support plate and the relative tilting mobility of the pressure plate on the clamping element.

In a further expedient embodiment, even two support plates are provided with the same wedge cross-sections. The two support plates can be combined so that their mutually remote surfaces are inclined either parallel to each other or at an angle. For this purpose, a support plate only needs to be rotated by 180 °. With the angle enclosed by the surfaces, a predetermined rotational position of the yarn feeding device can be adjusted on the square clamping profile.

In the support plate may also be provided a V-shaped recess for the circular cross-section of the clamping profile. Such a V-shaped depression is particularly useful if the support plate has a wedge-shaped cross-section, for example in order to set a rotational position of the yarn feeding device in the case of a square clamping profile. In this case, an undesirable side force would possibly arise during assembly of the same yarn feeding device on a round cross-section clamping profile, but this is avoided with the two cooperating V-shaped depressions in the pressing plate and in the supporting plate.

The coupling between the clamping screw and the pressing plate can be formed in terms of manufacturing technology simply in that the clamping screw receives a thread-free end pin following a shoulder, which passes through a bore of the pressing plate provided approximately in the deepest region of the V-shaped recess and in the V-shaped recess is riveted. In this way the relative rotatability and e.g. a certain tilting mobility of the press plate er¬ aims.

A yarn processing system S in FIG. 1 comprises a textile machine T, such as a knitting machine K (circular knitting machine or flat knitting machine), a carrying device P, and a plurality of yarn feeding devices F held and positioned on the carrying device P. The carrying device P is, for example, a ring from a clamping profile 1. Each yarn feeding device F is fixed to the clamping profile 1 with a fixation B. Y threads are supplied to the knitting systems by the yarn feeding devices F, wherein the yarn feeding devices F are positioned on the carrying device P in such a way that optimum yarn geometry is produced (for example, approximately the same length, shortest possible paths without significant deflections).

Although a flat cable 2 is indicated in FIG. 1, to which at least one of the yarn feeding devices F is connected (for power supply and / or within a communication or control system), it would alternatively be possible to connect each yarn feeding device to its own cable. The flat cable 2 is expediently on the support device P ₁ preferably installed on the clamping profile 1, such that each attached yarn feeding device F is directly connected by means of later explained Kontaktierungs- members galvanically connected to the corresponding wires of the flat cable 2.

Although the yarn processing system S in FIG. 1 shows a knitting machine K with knitting yarn delivery devices F, the inventive principle can also be realized in other yarn processing systems, e.g. a loom and weft-supplying devices, wherein the yarn feeding devices are hanging down on ei¬ nem one or more clamping profiles of a so-called state supported and aligned.

Fig. 2 illustrates, for example, in Fig. 1, the leftmost yarn feeder F shown with its fixation B on the clamping profile 1 of the support device P in operationally fixed position. The yarn feeding device F has a housing 3 and, for example, a storage body 4. The fixation B is either part of the housing 3 or fixed to this.

The fixation B has an open along a longitudinal side of the housing 3, in the basic traction four-edged cutout 5, which is bounded by a free-ending leg 6, a leg 3 striving to the housing 3, and in this embodiment, a flat support 9. In the leg 6, in at least one threaded bore, a clamping element 7, e.g. a clamping screw, adjustable arranged or screwed. As shown, a recess 10 for the flat cable 2 (see FIG. 1) can be provided in the support 9. In the recess 10, if necessary, housing-fixed contacting members 11 are placed into which the flat cable 2 is pressed.

The clamping profile has a round cross-section R (a tube or a solid round profile) and is inserted into an adapter part A, which lies with a flat side 15 on the support 9 and, if appropriate, also on the leg 8 is present. The adapter part A has a round recess 13 with at least substantially the same radius of curvature as the round cross section R, and lateral legs 14. The recess 13 extends spielsweise over 180 ° in radians, or less or more. To set the Operating position of the yarn delivery device F can, before tightening the Klemmelemen¬ tes 7, the housing 3 around the core axis of the round profile R in the direction of Doppel¬ arrow 17 back and forth rotated. The flat cable 2 is pressed by the flat rear side 15 of the adapter part A into the contacting members 11. In this case, the support device P may be a ring frame of the clamping profile 1 with the Rund¬ cross-section R, on which the other yarn feeding devices F are set in the same way. The adapter part A is used to change the square configuration of the cutout 5 in a round configuration.

In the event that the carrying device P should have a clamping profile 1 with a square cross-section V or V1 (FIGS. 3, 4), the fixing B can be changed from the round configuration shown in FIG. 2 to the original square configuration (FIG 3 and Fig. 4). For this purpose, the adapter part A of FIG. 2 is removed. The clamping profile 1 rests directly on the support 9 and is pressed by the Klemmele¬ element 7, wherein it also presses the flat cable 10 in the recess 10, and optionally also on the leg 8 is supported.

In the case of Fig. 4, the square cross section V1 is thinner than in Fig. 3. For this reason, it is appropriate to form the leg 8 divided so that its parts 8a and 8b are adjustable relative to each other to the distance between the free ends to be able to adjust the leg 6 and the support 9. The adjustability may e.g. be accomplished by a toothing or a screw.

5 illustrates another embodiment of the fixation B of a yarn delivery device F which permits at least one additional adjustment about an axis 21 which runs approximately parallel to the direction of the leg 8, for example farther to the left than in FIG. The fixation B may be an integral part 16, on which the legs 6, 8 and the support 9 and the cutout 5 are provided with a square configuration. The contacting members 11 are placed in the recess 10, adjacent to the support 9, and connected via flexible conductors 19 to a power interface 18 in the housing 3. Expediently, the flexible conductors 19 are laid with excess length and free so that they tolerate the rotation of the fixing B about the axis 21 relative to the housing 3. Dashed lines in Fig. 5 a kind of ball joint J between the fixation B and the Ge housing 3 is indicated, so that the housing 3, for example, about an axis perpendicular to the core axis of the clamping profile 1 axis, mainly in a square clamping profile 1, is adjustable ,

To protect against damage to the conductors 9, it is expedient to provide a non-ge limit for the respective adjustment. The fixation B can be e.g. by means of a fastener 20 set in different Einstellla¬ conditions, which should be accessible from the outside expedient even with mounted yarn feeding device F (for example, by a shaft 29). For the conductors 19 Aus¬ sections 25 could be recessed in the ball joint area. For the head of Befestigungs¬ element 20 could be a convexly rounded or stepped support 27 may be provided to achieve a secure fixing in each adjustment position.

In FIG. 5, the fixing B has the square configuration for fixing, for example, to the clamping profile 1 with the square cross-section V or V1 (FIG. 3, FIG. 4). To convert the fixation B into a round configuration, the adapter part A shown in FIG. 2 (or the adapter part A shown in FIG. 7) is inserted into the cutout 5 and positioned with the flat rear side 15 on the support 9, before the clamping profile 1 is inserted with the round cross section R and fixed by means of the clamping element 7. In this case, if present, the flat cable is pressed into the recess 10.

Fig. 6 illustrates in a plan view of the housing 3 of the yarn feeding device F, the arrangement of the fixation B on the housing side, wherein the axis 21 is highlighted.

The adapter part A of Fig. 7 differs from that of Fig. 2 in that the recess 13 'is not round but V-shaped and open at the top. Optionally, at least one V-edge is provided with a structuring S or with steps in order to increase the frictional resistance when clamping the yarn feeding device. FIG. 8 illustrates another embodiment of the fixation B which can be used for the delivery device F in FIG. 5 or in FIG. 2 and has a reversal of the principle of FIGS. 2 and 5. The cutout 5 is basically formed with a round configuration in which it is delimited by the legs 6 and 8 on two sides and a round (or V-shaped, as in FIG. 7) recess 22 in the flat support 9 '. To Be¬ attachment to a circular cross section R, the clamping profile 1 is inserted directly into the recess 22 and clamped by means of the clamping element 7. The recess 10 'with the contacting members 11 follows the contour of the round recess 22. If a flat cable is present, this is pressed by the clamping profile 1 directly into the recess 10' and thus on the contacting members 11. To change the fixation B in FIG. 8, an adapter part A '(indicated by dashed lines) is used which has a concave curvature 24 corresponding to the recess 22 and a flat rear side 23 onto which the clamping profile 1 with the square cross section V or V1 (Fig. 3, 4) is pressed. The embodiment of Fig. 8 has a geometric configuration (thanks to the recess 22 and the support 9 '), which basically either optionally fits on a round or a square clamping profile ¹ , without the need, with an adapter part A ¹ or A " to manipulate.

In the event that no flat cable 2 is installed on the clamping profile 1, but the Fa den dengeräts is connected to another cable, could be used as adapter part A ¹ for the square profile in Fig. 8 even only a flat plate or the Klemm¬ profile. 1 be inserted directly into the recess 22.

8, an adapter part A "with the shape of a cylinder section is indicated to at least slightly rotate an impressed square clamping profile 1 relative to the fixation B and thus to be able to adjust the yarn feeding device F. Here, a structuring S _1, for example ribbing, is provided be to increase the friction engagement or even form-fitting to define adjustment steps.

Fig. 9 illustrates an additional function of the adapter part A, for example, according to FIG. 2. And although the adapter part A is additionally designed with the function of a retaining clip C for fixing the flat cable 2 when installing on the clamping profile 1 with the Rund¬ cross-section R. The two legs 14 extend for example via more than 180 ° in radians, so that they can be snapped onto the clamping profile 1 under the elasticity of the material of the adapter part A. In the flat rear side 15 of the adapter part A, a positioning device 12 for fixing the flat cable 2 is provided. These can be molded hooks or similar elements which, preferably, are formed integrally with the adapter part A.

The adapter part A shown in FIG. 9 can be used where a thread delivery device is to be defined. Apart from that, such adapter parts A as retaining clips C can also be used at other locations along the clamping profile 1 for installing the flat cable 2, where no yarn feeding devices are mounted.

It is expedient to form the adapter part as a plastic molded part, preferably an injection molded part, although it could, for example, also be cut off from an extruded light metal profile.

In the embodiment in FIG. 10, an adjustment of the yarn feeding device F about the core axis of the square clamping profile 1 is possible, at least in a limited adjustment range. The cutout 5 has a square configuration with the flat support 9 and, if necessary, the flat cable recess 10. The adapter part A, which is used for switching to a round configuration, is combined with a second adapter part A " ¹ , which has a convexly rounded rear side and As a result, the fixation B, provided that the clamping profile 1 adheres to a distance from the leg 8, can be approximately arranged about the core axis of the clamping profile 1 and firmly clamped in each case the adapter parts A, A "'with structuring S formed to reinforce the frictional engagement, or, for example, with ribs or teeth to define adjustment stages.

The embodiment of the yarn feeding device F shown in FIGS. 11 and 12 differs from the preceding ones by a fixation B which is used to mount the yarn feeding device F to clamping profiles 1 of different thicknesses and widths and with both a square cross section and a round cross section without conversion ment and without disassembly or installation of components is useful. The legs 8 with the clamping element 7 on the yarn feeding device F positioning leg 8 is fixed to a base 46 of the housing 3, for example, in one of several Fixier¬ positions. 11 shows a fixing position in which a fastening screw is seated in a bore 34 of the leg 8 (indicated by a cross), so that the leg 6 has a maximum distance from the support 9 on the housing 3. If a shorter distance of the leg 6 is required, then the screw is introduced into the other bore 33 and the leg 8 is inserted further than shown in FIG. 11. With the clamping element 7 designed as a clamping screw, a pressing plate 31 is movably connected to its end engaging in the cutout 8. The press plate 31 (for example, a sheet metal bent part with a constant thickness) has on the side facing the yarn feeder a recess, for example an approximately V-shaped depression, which is symmetrical in cross section to the axis 21 'of the clamping element 7 (FIG over the length of the press plate 31 (see Fig. 11) durch¬ goes.

In the recess 35, the opening angle can be 120 °. He should be greater than 90 °. Substantially flat pressing surfaces 36, 37 adjoin both edges of the depression 35 and lie in a common plane perpendicular to the axis 21 '. The pressing surfaces 36, 37 are located on lateral edge strips of the pressing plate 31 and terminate at, for example, straight and mutually parallel edges 38, 39.

The press plate 31 can be installed in two fixing positions B rotated by 180 ° about the axis 21 '. In one operating position, which is shown in solid lines in FIG. 12, the edge 38, since the edge strip with the pressing surface 36 is narrower than the edge strip with the pressing surface 37, forms a tilting position setting gap 44 with the inner wall of the cutout 5 certain size. In the other operating position indicated by dashed lines in FIG. 12 (shown in solid lines in FIG. 15), the other edge 39 forms a narrow guide gap 45 with the wall of the cutout 5.

The pressing plate 31 is movably connected to the clamping element 7, preferably via a form-fitting coupling 40, in such a way that the pressing plate 31 is tiltable. movements are possible at least in the direction of a double arrow 42, and the clamping element 7 can rotate relative to the pressing plate 31 about the axis 21 '. The plan view in FIG. 14 shows a rectangular or square outline shape of the pressing plate 31, the length of the pressing plate 31 being greater than the width of the leg 6, so that the pressing plate 31 protrudes from the cutout 5 on both sides. The pressing plate 31 is, for example, a section of an endless profile.

The coupling 40 is formed, for example, in that a thread 51 which is offset from the threaded section of the clamping element 7 via a shoulder 51 passes through a bore of the pressing plate 31 and is caulked or riveted inside the recess 35. The bore is set at the lowest point of the recess 35 and, for example, in the longitudinal center of the press plate 31.

On the leg 8 11 and 12, a support plate 32 is movably guided in the direction of Schen¬ cle 8 in FIG., Which, for example, also rectangular or square outline shape and in FIGS. 11 and 12 has constant strength. The support plate 32 is intended to be placed on the flat support 9 of the yarn feeding device F in order to hold the flat cable 2 (see Fig. 15, 13) in the depression 12 and to transmit the contact pressure to the support 9.

In Fig. 13, the yarn feeding device F is mounted with the fixation B on a clamping profile 1 with a circular cross-section R. The circular cross-section contacts the recess 35 at two spaced, linear contact areas and the support plate 32 at one side, wherein the support plate 32 rests with the other side on the support 9. The yarn feeding device F can be fixed around the core axis of the clamping profile 1 in the direction of a double arrow 17 in the respectively desired rotational position.

In Fig. 14, the yarn feeding device F is fixed relative to the clamping profile with the circular cross-section R in a pivoted position, wherein the pressure plate 31 has rotated in the context of the gap 44 (Fig. 12) with. This tipping position adjustment is indicated by a double arrow 30. The fixation B is designed so that it fits to round sections R of different diameters. With a smaller diameter than that shown, the leg 8 could be fixed in the lower position in the base 46.

In Fig. 15, the yarn feeding device F is fixed to the storage body hanging down with the fixation B on a clamping profile 1 with square cross section V, wherein the pressing surfaces 36, 37 rest on the clamping profile 1 and the support plate 32 on the Auf¬ 9. The pressing plate 31 is placed in the other operating position, in which the edge 39 forms the narrow guide gap 45 with the wall of the cutout 5, so that the pressing plate 31 can not rotate appreciably about the axis 21 'of the clamping element 7. Further, in Fig. 15, the leg 8 is fixed in the lower setting on the base 46. Incidentally, the support plate 32 could otherwise be omitted, for example in the case of a high square cross section V, so that the square cross section then rests directly on the support 9.

The platen 32 is fixed to the leg 8 e.g. with a game, in a kind of dovetail leadership. Hook-shaped parts 48 of the support plate 32 hintergrei¬ fen undercut guide edges 47 of the leg 8, so that the support plate 32 is captive in the direction along the leg 8 is movable, in which the Boh¬ ments 33, 34 are behind each other. The leg 8 could have a square cross-section, so that the dovetail guide is then formed between the support plate 32 and side edges of the leg 8 which are not undercut.

Fig. 17 illustrates, in contrast to the support plate 32 in Figs. 11, 12, 13 and 15, a support plate 32 ', which has a wedge-shaped cross-section, for example, such that the thickness of the support plate 32' with distance from the parts 48 decreases. In this way, even with a square-type clamping profile, the yarn feeding device F could be mounted slightly rotated, so that the axis 21 'of the clamping element and, if appropriate, of the yarn feeding device would be opposite the vertical, e.g. 50 is slightly inclined from the clamping profile defi¬ ned direction.

FIG. 18 illustrates a support plate 32 ", which also has a wedge-shaped cross-section, in order to utilize the tiltability of the press plate 31 on the clamping element to allow above-described rotation of the yarn feeding device on the clamping profile 1 with Vierkant¬ cross-section V. However, in order to prevent lateral forces on the upper side of the support plate (as in the support plate 32 ') when fixing the same fixation B on a circular cross-section R, the support plate 32 "is provided with a V-shaped recess 49 for round cross-sections flat surface areas for attachment to a square.

When using the support plate 32 'or 32 "instead of the support plate 32 in Fig. 15, the yarn feeding device F could be mounted ver¬ rotates relative to the clamping profile 1, for example clockwise.

Incidentally, the support plate 32 (32 ', 32 ") can be removed from the fixation B in such a way that it is removed from the leg 8 after removal of the leg 8 from the pedestal 46.

FIGS. 19 and 20 illustrate a further embodiment detail variant in order to be able to set both a positioning of the yarn feeding device as shown in FIG. 15 on a square V and also a twisted positioning according to FIG. 17. In fact, the platen 32 is arranged in two support plates 32 '. '32' ', each having such a wedge cross-section, such that the two support plates 32', 32 '' in the Kombi¬ nation according to FIG. 19 define mutually parallel sides, which lie perpendicular to the axis 21 ', while they In the other operating position shown in Fig. 20, for example, by turning the lower platen 32 '' 180 ° so that the sides are at an angle to each other, one side is perpendicular to the vertical direction 50, while the other side is perpendicular to the vertical direction Axis 21 'lies with this combination can be in the square, for example, of Fig. 15, the yarn feeding device F in a against Mount in a counterclockwise rotated position above the position shown in FIG.
