Description

Heald, preferably for processing band-shaped warp material and

Method for producing a heald

Healds are known from the prior art, the shaft is made of two bands.

For example, EP 2 730 688 A1 and EP 2 730 687 A1 disclose healds

Processing of preferably band-like warp material whose shaft is formed in each case from two bands. In the region of the two ends of the shaft end loops are formed. In the middle region of the shaft, the two bands are spaced apart by at least one component, whereby a thread eye is formed. In the remaining area of the shaft, the two bands abut each other. The healds can be produced relatively inexpensively, but have the disadvantage that in the operating position, ie, when the healds are inserted by means of the end eyelets in the support rails of a loom, the healds due to the usual game between the support rails and the end eyelets of the strands, these over rotate a larger angular range around your longitudinal axis, ie can noticeably tilt. In weaving operation, this skewing of the strands causes the warp threads (warp strips) adjacent to the strands to grind stronger than usual (or even at all) on the healds. This can lead to damage and, in the worst case, tearing of the bands in question.

From EP 1 795 636 A1 a heald is known, whose shaft is constructed of two bands, which are arranged at a distance parallel to each other. Between the two bands at least two thread support elements are arranged. The thread support elements together with the bands form a flat, oriented transversely to the warp thread and the longitudinal direction of the strand Thread eye. At the ends of the two bands respectively end loops are formed, which serve to receive the strand to carrier rails of weaving machines. Since the heald has a constant width over its entire length, this heald has the disadvantage that when weaving the warp threads relatively frequently grind on the heald, even if the heald only slightly skewed during operation. Another disadvantage is that the production of the heddle is comparatively complicated and expensive.

For the above reasons, the object of this invention is to provide a low-cost heald, in which the friction between the strand and the warp straps is minimized in the weaving operation, ie, the grinding of the warp bands on the heddles should both in terms of frequency and be minimized in terms of intensity.

To solve this problem, the present invention proposes a

A heald according to claim 1 and a method of making a heald according to claim 15.

It is assumed that a heald, which is preferably suitable for processing band-like warp material. Hedges are generally elongated bodies, that is, the heald according to the invention has the largest dimension in its longitudinal direction L. The heddle also extends in a transverse direction Q and a warp direction F. The transverse direction extends in the direction of the width of the

Fadenauges and the warp direction runs during operation of the heald (approximately) in the direction of those warp threads that are not deflected (due to a shedding). The longitudinal direction, the transverse direction and the Kettfadenrichung are each (in pairs) perpendicular to each other and thus form a Cartesian

Coordinate system.

The center axis of the heddle should be considered the one in the longitudinal direction

extending axis (straight line) to be defined, to which the shaft of the strand over the largest extent in the longitudinal direction is axisymmetric. The heald comprises at least two bands (preferably exactly two bands) which form the Litzenschaft, at least one component (preferably exactly two components), which serves to limit the Fadenauges and at least two end eyelets (preferably exactly two end eyelets), which each located at one end of the Litzenschafts and for receiving one end of the strand on a mounting rail (usually by hanging) a

Serve loom in which the strands are to be used.

In accordance with the invention, the strand has a fixed by the geometry of the bands contour in the transverse direction, which has a novel course. The course relates, as will be explained below, first, the area of the thread eye, second, the between the region of the thread eye and the

Third part of the shaft extending portions of the shaft and third, the area of at least one end eyelet.

Thus, first, the at least two bands are spaced in the region of the thread eye in the transverse direction. The at least one component is arranged in the region of the thread eye between the at least two bands and usually serves for spacing the bands.

[001 1] Secondly, the at least two bands (2, 3) lie against each other in the longitudinal direction in front of and behind the thread eye (8) at least in sections.

Preferably, the bands rest against each other over most of their length, e.g. over at least 60%, at least 70% or at least 80% of the total length of the strand. The "abutment" of the bands together should be understood to mean a concern that occurs when two planar elastic bands are placed in one place (e.g.

punctiform) are connected to one another in such a way that they have no distance from one another at the point in question, at least within the limits of the manufacturing tolerances, and the two bands rest loosely against one another in the remaining regions remote from this point. The term concerns should not be ruled out in this context, that at rest form fine air gaps between the bands, nor that the bands in the other areas in places for a short time from each other, if the associated strand, eg during weaving, (fast) is moved. Third, at least one of the at least two bands (seen in the longitudinal direction) in the region of at least one of the at least two end eyelets (ie in at least one first end eyelet region) at least one of

Transverse to the one side away from the central axis of the heald. At the same time, at least one of the at least two bands of at least one further point of an end eyelet region is to extend to the other side in the transverse direction away from the central axis of the heddle. The two abovementioned locations (in the area of the end eyelets) may be located in the same position (longitudinally), they may be located at different positions in the area of the same end eyelet or they may be in the region of different end eyelets. The shape in question of the at least two bands in the region of the at least one end eyelet should in this case be chosen such that in the installed position, that is, when the

Hedgehog according to the invention is hung with its end eyelets on each support rail, the free rotation angle around the central axis of the heald (i.e., the degree to which the healds can skew due to common play between the at least two end eyelets and the associated support rails) are minimized. For this purpose, it is necessary for the abovementioned at least two points, at which the at least one band of the heddle (in the region of at least one end loop) extends transversely away from the central axis, to be mechanically in contact with one of the mounting rails in the installed position.

Under an Endösenbereich (ie the region of the at least one end eyelet) is that part of the strand to be understood that begins in the longitudinal direction at that end of the strand on which the respective Endöse is, and at a distance of one quarter , preferably one fifth, more preferably one sixth of the total length of the heald from the respective end of the heald (removed) ends.

When using the heddle according to the invention, the friction between the warp threads and the healds occurring during the weaving process is minimized by minimizing the skew of the healds during the weaving operation and by providing the heddle in the areas of the tine shaft extending between the thread eye and the heddle the end eyelet areas are a small Has extension (usually the sum of the thickness of both bands) in the transverse direction and consequently a grinding of the warp threads at these areas of the

Heald according to the invention is largely excluded.

In a preferred embodiment, the minimization of the maximum possible inclination of the heald (ie, the free rotation angle about the central axis of the heald) during weaving achieved in that the at least two bands in the region of at least one of the at least two end eyelets at least partially in transverse calibration are spaced. Preferably, the heddle has exactly two end eyelets, wherein the bands are at least partially spaced in the region of both end eyelets. In the heddle according to the invention, an end eyelet is always composed of at least two bands which are each provided with an end eyelet recess. The term end-eyelet is intended herein to encompass all bands with end-loop recesses located at one end of the heald, regardless of whether the bands abut one another in the respective end-eyelet region or are spaced apart transversely.

In a further advantageous embodiment, the minimization of the maximum possible inclination of the heald (the free rotation angle about the central axis) is achieved in that extends in an Endösenbereich at least one of the at least two bands at least partially in the transverse direction to one side away from the central axis and in another Endösenbereich at least one of the at least two bands at least partially in

Transverse to the other side away from the central axis runs.

In the conventional healds, the end loop recesses are approximately (longitudinally) arranged in a line (i.e., in alignment).

Due to the play that usually prevails between the end loops of the heald and the associated support rail, in such a (substantially linear) arrangement of the end loops, the strand can rotate about relatively large angles about the central axis, i. it is possible a strong inclination of healds. If, on the other hand, the end eyelets are not arranged in a line (not in alignment), then have

For reasons of geometry, the clearance (still present in approximately the same order of magnitude) between the end eyelets and the mounting rails is much smaller Twisting / skewing of the strands result, ie, the possible angle of rotation about the longitudinal axis is much smaller (anti-rotation). The further the maximum offset (the distance in the transverse direction) of the bands in the region of an end eyelet and / or the bands in the region of different end eyelets is, the more effective the maximum possible inclination / the maximum possible

Angle of rotation minimized. Decisive are again only the areas of the bands that are in mechanical contact with a mounting rail.

Another cause for the skewing of the strands may be that the strands twist mechanically about the longitudinal axis (ie, "twisting") .The effect is so small that in the case of conventional heddles (with linearly arranged end eyelets However, this effect can not always be neglected in the healds according to the invention in which the skewing of the healds during weaving operation is largely eliminated due to backlash between the strand and the support rail Heald be useful or necessary.

The end eyelet portions of the heald of the invention may be made solely by plastic deformation, e.g. by bending the respective areas (plastically) into the desired shape or by achieving the shape by means of at least one forming operation.

In the embodiments in which in the region of at least one end eye, the two bands are spaced apart in the transverse direction, alternatively or additionally (for plastic deformation) in the region of at least one end eyelet at least one spacer element between the at least two spaced bands can be arranged , The spacer causes the spacing of the two bands in the transverse direction or at least supports them.

Although the preparation of healds with spacers is somewhat more expensive and therefore more expensive (as the production exclusively by plastic deformation). However, the spacers have the advantage of being increase the torsional stiffness of the healds, whereby, as stated above, the inclination of the healds in weaving operation is further minimized.

Preferably, the at least two bands spaced in the region of both end eyelets, wherein for spacing the same means, such. plastic

Deformation, spacers or a combination of plastic deformation and spacers, can be used. Also, the at least two bands in the region of both end loops can each be separated from each other by the same maximum distance. The heddle may also be constructed symmetrically in the transverse direction, e.g. in that the at least two bands are bent in the transverse direction in each case symmetrically with respect to the central axis.

In the embodiment in which the at least two bands are spaced (at least in sections) in at least one endose region, preferably the two bands are at the associated end of the strand (i.e., at the end where the respective endose region is located)

spaced. The bands are then bent in this endose area (approximately) u- or v-shaped. Alternatively, however, the two bands can also (although in the region of the at least one end loop be spaced apart from one another) on

associated end of the strand, the bands abut each other. The two ends then show an approximately o-shaped course.

Healds arranged adjacent to each other on a support rail may typically move along the support rail (i.e., in the transverse direction of the heald). In Webbetrieb the healds are then held only by the warp threads in an approximate position. This inaccurate positioning in the Q direction leads, especially in the case of band-like warp material, to increased grinding of the warp threads on the strands in question. In the processing of

band-like warp material is therefore often the strands to the exact

Positioning in the Q-direction, for example by means of brackets, attached to the support rails (ie locked in the transverse direction), which, however, a significant overhead in the equipment of the looms is caused. In a further advantageous embodiment, therefore, the sum of the distances by which each at least one band in the region of at least one end loop extends transversely away from the central axis to one side and at least one band in the region of at least one end eye with respect to the Center axis to the other side extends (hereinafter referred to as "width of the heald"), greater than the extent (ie, the width) of the thread eye in the transverse direction.As a result, the width of the heald, this on the

Carrying rails occupies greater than the width of the thread eye of the respective heald. The healds can then be supported against each other in the region of the end eyelets / the support rails, whereby a movement of the strands along the

Support rails prevented or at least minimized.

The width of the heald is preferably chosen to be just as large as the average (regular) distance of the strands on the mounting rails. This regular

Distance of healds corresponds in many cases, almost exactly twice the width of the thread eye. In these cases, preferably twice the width of the thread eye is selected as the width of the strand.

If the strands are elastically deformable in the region of the support rails, for example, if the strands are U- or V-shaped at their ends and / or e.g. made by pure bending, the distance can also be chosen slightly larger than the regular distance. The strands are then inserted under tension and are optimally positioned by the spring forces occurring.

In a further advantageous embodiment, the at least two bands at one point of the strand, on which the at least two bands are not

are spaced and the (in the longitudinal direction) in one-third

(Preferably, in a quarter, more preferably in a fifth) of the heald is arranged, in which there is at least one end eyelet, connected to each other by means of at least one stabilizing element. By the stabilizing element, similar to the spacer elements, the

The torsional rigidity of the heald increases (the friction between the warp straps and the healds is minimized). The connection is preferably so rigid that in the region of the connection point, a relative movement of the two bands at least in

Warp direction is suppressed (microscopic movements, as they are possible with rigid / solid materials due to minimal deformation, should be disregarded).

The at least one stabilizing element may be punctiform or linear, e.g. as a point or line weld or as a riveting point. Preferably, the stabilizing element is disposed in the vicinity of the end loops, e.g. if the at least one stabilizing element is less than 1.5 cm,

Preferably, less than 0.75 cm from the point in the region of the end eyelet, at which the two tapes come together after their spacing (that is, for the first time abut each other again).

A simplified production of the thread eye is thereby made possible that in the longitudinal direction at least a first connection point, preferably a connection point, above the thread eye and at least a second

Junction (also preferably a connection point) below the

Fadenauges are arranged. In this case, the at least one first or the at least one second connection point (preferably both connection points) at a distance from the thread eye, which is less than half, preferably one third, more preferably a quarter of the distance (in the longitudinal direction) between the thread eye and the the connection point respectively nearest Endöse. If the at least one component is clamped between the at least two bands, then the short distance between the connection points usually leads to a relatively high normal force, which ensures a secure hold of the at least one component.

In a preferred embodiment, the at least one

Component on at least two fasteners, and the two bands each have in the area in which the thread eye to be formed, at least one (geometrically corresponding) fastener. The at least two fastening elements of the at least one component are set up with the respective at least one component of the bands To make a connection, which serves to position the at least one component between the at least two bands and or to secure.

In this way it is possible healds with thread eyes, which are suitable in particular for ribbon-like warp material, uncomplicated and inexpensive to manufacture. The at least one component can be held by a normal force (clamping force) without further measures between the two bands. Alternatively, the device may be additionally glued. In this case, the normal force ensures positioning until the adhesive has cured. After curing of the adhesive, the clamping force continues to support.

To produce the heddle according to the invention, the bands are cut in a first step, i. E. adjusted to the correct length, e.g. by punching, cutting or other separation methods. In a next step, the end eyelets, preferably by means of punching, are introduced into the bands.

Subsequently, at least one fastener, which later serves for positioning and / or attachment of at least one, the thread eye delimiting component, on the relevant band (at the point at which the thread eye to be formed below) is formed. Preferably, in each case at least one recess (as a fastening element) is introduced into the two bands, in each of which a corresponding elevation (as

Fasteners), which is formed on the at least one component, engages accurately. Alternatively, v- or u-shaped cuts in the bands can be introduced, and then the cut

Sheet metal sections (sheet metal tongues) by approx. 90 ° out of the plane of the strip

be bent out. At the components recesses are present, in which the projecting from the bands sheet metal sections / sheet metal tongues can intervene.

Preferably, at least two bands, as described in detail above, by plastic deformation (eg Bent) in the region of at least one end eyelet shaped so that after the (later) joining of the two bands at least one band in the Endösenbereichen in one of the two transverse directions away from the central axis of the heald. In this way, the means of production of the

Anti-twist protection already in an initial punching and bending process (resp.

Forming process) can be produced very cheaply without separate

Work steps become necessary.

To form the thread eye, the at least two bands are connected to one another via their flat sides at at least two connection points which are respectively arranged in the longitudinal direction above and below the region in which the thread eye is to be formed (eg by means of spot welding), ie the two joints comprise in the longitudinal direction of the area where the thread eye is to arise. Directly afterwards or later

At the time of strand manufacture, at least one stabilizing element, e.g. by spot welding, in the area of at least one of the end loops are created or attached.

Subsequently, in the region of the at least two bands which extends in the longitudinal direction between the two connection points, a distance between the two bands is generated in the transverse direction, for example by the bands are pulled apart by applying a force in the transverse direction. The at least one component which serves to delimit the thread eye is then introduced into the respective spaced region. Preferably, two, for example, rod-shaped, components are introduced into the spaced area, wherein the upper and by the other component, the lower side of the usually rectangular Fadenauges is limited by one component. The remaining (lateral) part of the thread eye is bounded (formed) by the at least two bands. The components may be connected by fasteners to the bands formed on both the components and the bands. The fastening elements of the components can, as described above, engage in the fastening elements of the bands or, conversely, fastening elements of the bands can engage in the structural elements. Unless the bands already in the before their joining

Endösenösen areas were plastically deformed, the bands can be plastically deformed even after their assembly (in the area of the end eyelets). Alternatively or additionally, spacing elements between the at least two bands can also be introduced in the endose area.

With the method according to the invention, it is possible to inexpensively produce healds, which are very well suited for band-like warp. As stated above, the heddle made by the method has a

Geometry, which largely prevents the friction between the healds and the warp straps during weaving operation. It is not necessary to reduce the play between the Endöse and the Litzentragschiene.

The invention will be explained in more detail below with reference to several exemplary embodiments, in which:

Transverse region of a first Endösebereichs in the transverse direction in one direction and extend in the region of a second Endösebereichs in the transverse direction in the other direction. 1, the heald consists of a first 2 and a second 3 band, as well as two components 4, by which the two bands 2, 3 in the region of the thread eye 5 in the transverse direction Q are spaced. To the

Thread eye area closes on both sides in the longitudinal direction L one each

Shank area 6 on. In the shaft regions, the two bands 2, 3 abut each other over a long distance. In the end eyelet regions 8 (regions of the end eyelets 7), the two tapes are bent apart in the transverse direction (up to the respective heald end 9) by a length I that is greater than the width f (in the transverse direction Q) of the thread eye 5. In addition, spacing elements (10, see Fig. 7) can also be introduced between the two bands in the end eyelet regions 8. The length I is chosen so large that the healds 1, when attached to the support rails of a weaving machine (not shown) with their bands 2, 3 respectively adjacent to the band 2, 3 of an adjacent heald 1 (in the end eyelet area), so that the bands 2,3 (and thus the healds 1) in the transverse direction Q can not practically (ie not noticeably) move on the respective support rail.

For further mechanical stabilization, stabilizing elements 12 in the form of spot welds are respectively used in that one fifth of the heald, in which one of the end eyelets 7 is located, by means of which the two bands 2, 3

connected to each other. In the longitudinal direction L above and below the

Fadenauges 5 each a first 13 and a second 14 connection point is arranged. The connection points 13, 14 are also made by spot welding. The first 13 and the second 14 connection point has in each case a distance a from the thread eye 5, which is substantially less than half the distance b between the thread eye 5 (the center of the thread eye 5 in the longitudinal direction) and the respective connection point 13, 14th each

nearest end eyelet 7 (the center of the end eyelet 7 in the longitudinal direction).

As can be seen from FIGS. 4 to 10, the end eyelet regions 8 can be shaped differently. In comparison, Fig. 3 shows a heald with linearly arranged end eyelets 7 according to the prior art. Thus, Fig. 4 healds 1 with Endosenbereichen 8, in which the two bands 2, 3 abut each other again at the end of the strand 8 (ie, o-shaped strand ends 9), wherein the two Endösenbereiche 8 are shaped the same. Fig. 5 also shows O-shaped end eyelet portions 8, but these are shaped differently (mirror inverted). Fig. 6 shows a heddle in which there is an O-shaped endose area 8 on only one side.

Fig. 7 shows healds 1 with Endosebereichen 8, in which the bands are 2.3 spaced apart at the end of the strand (U / V-shaped stranded ends 9) and which are the same shape at both Endosenbereichen 8. The third heald from the right is also provided with a spacer element 10, which spaced the bands 2, 3 in the region 8 of the end eyelets 7 from each other. Fig. 8 shows healds 1 with u- / v-shaped endose regions 8, but the end eyelet regions 8 differ

(mirrored) are formed. Fig. 9 also shows healds 1 with a bulky endose area 8, wherein only one endose area 8 is widened.

Finally, FIG. 10 shows a heald 1 in which in one of the end eyelet regions 8 both bands of the heald 1 are bent with respect to the central axis 15 in the transverse direction Q to the one side and in the other endose area 8 to the other side (with respect to the central axis).

Thread eye (5) are arranged, wherein the at least one first or at least a second connection point (13, 14) has a distance (a) from the thread eye (5), which is less than half of the distance (b) between the thread eye (5) and the connection point (13, 14) respectively proximal end eyelet (7).

14. heald according to one of the preceding claims, characterized in that the at least one component (4) at least two

Has fastening elements, and the two bands (2, 3) in the region (8) of the thread eye (7) each have at least one geometrically corresponding fastening element, wherein the at least two

Fixing elements of the at least one component (4) thereto

are arranged, via the at least one fastening element of the bands (2, 3) each enter into a connection with which the at least one component (4) in the region of the thread eye (5) between the

at least two bands (2, 3) is positioned and / or fastened.

15. A method for producing a heald, comprising the following steps

includes:

- cutting to length at least two bands (2, 3),

Inserting end eyelets (7) into the at least two bands (2, 3),

- Producing at least two connection points (13, 14), which connect the bands (2, 3) mechanically to each other, wherein the connection points (13, 14) in the longitudinal direction (L) above and below that portion of the bands (2, 3) are produced in which a thread eye (5) is to be formed,

- Forming a distance between the two bands (2, 3) in the

Subarea located between the at least two connection points (13, 14),

Inserting the at least one component (4), which serves to delimit a thread eye (5), into the spaced area,

- wherein the bands (2, 3) before the production of the two connection points (13, 14) in the region (8) of at least one of the end eyelets (7) are plastically deformed and / or after the preparation of the two connection points (13, 14) Straps (2, 3) are plastically deformed in the region (8) of at least one of the end eyelets (7) and / or at least one spacer element (10) is introduced between at least one of the end eyelets (7) between the straps (2, 3), which serves for the spacing of the bands (2, 3).
