Description

The present invention relates to a heald for a heald of a loom. Such heddle shafts are equipped with a large number of strands, each strand has a thread eye through which a warp thread is guided in each case in the position of use of the strand. The healds are moved up and down during operation of the loom to form a shed into which the weft is entered. In modern weaving machines, the healds move up and down at high frequencies, which places high demands on the healds. Even with strong accelerations or delays of the heddles and the warp threads guided therein damage to the warp, as well as excessive wear of the heddle should be avoided. The design of the thread eye is therefore of great importance in order to avoid the mentioned problems.

The EP 1 795 635 A1 describes a heddle for tape-shaped warp threads. The thread eye of this strand is introduced substantially as a slot-shaped opening in a flat, ribbon-shaped strand body. In some embodiments, the thread eye is provided in the region of the thread support surfaces with a radius. This radius can be achieved by attaching separate cylindrical or partially cylindrical elements whose radiused edge is attached to the top or bottom of the thread eye. In another embodiment, adjacent to the top and the bottom of the thread eye introduced tongues from the Level bent out of the flat Litzenkörpers, whereby at the edge of the thread eye a bending radius is formed, which serves as a thread support surface for the ribbon-shaped strand.

Out US Pat. No. 6,283,163 B1 a heald is known which has a strand body made of a wire. Between two parallel wires of the strand body a Maillon is used, which forms the thread eye. The Maillon is provided to the thread eye with a radius.

US 6 145 549 also discloses a heddle for tape-like warp threads, which has a rectangular in cross-section strand body. The thread eye is designed in the form of a parallelogram, wherein the two edges forming the thread support surfaces extend obliquely to the horizontal and to the vertical. The thread eye is rounded on the Kettfadeneintrittsseite and Kettfadenaustrittsseite, wherein the thread support surface extends therebetween.

From EP 1 739 215 A1 known thread-saving heddle made of plastic has, in one embodiment, a thread eye, the thread support surfaces can be configured flat or channel-shaped. Furthermore, the thread eye can widen into a funnel-like manner towards the warp thread entry side or to the warp thread exit side. In the figures, this funnel-like extension is shown schematically in the form of a curvature. The course of the funnel-like extension is not described in detail. The disadvantage here is that the warp thread in the embodiment of the thread support surface in the form of a groove is only then guided laterally sufficient when it has contact with the thread support surface. If the warp thread lifts off the thread support surface, this is its lateral guide only guaranteed by the two running in the longitudinal direction of the strand body narrow guide webs, which are offset in the warp direction to each other. The hedge can twist around its longitudinal axis.

Starting from the known prior art, it can be regarded as an object of the present invention to improve the reception of the warp thread in the thread eye of the heald.

This object is achieved by a heddle with the features of claim 1.

According to the invention, the lateral guidance of the warp thread in the region of the thread eye is improved for improved reception of the warp thread. The thread eye is transversely to the longitudinal direction of the heddle body and transverse to the warp direction, in which the warp thread the thread eye from the Kettfadeneintrittseite passes through the warp thread exit side, bounded by a respective guide web. The distance between these two guide webs in the transverse direction is substantially adapted to the thickness of the warp thread and therefore often so small that it would not provide sufficient space for a Einziehnadel for drawing the warp thread. In this embodiment according to the invention, the guide webs therefore each have a central portion at which the Kettfadeneintrittsseite associated leading edge of a guide web in Kettfadenrichtung is spaced from the Kettfadeneintrittsseite the Fadenauges and of the Kettfadenaustrittsseite associated trailing edge of the other guide web, the trailing edge of the Kettfadenaustrittsseite the thread eye is spaced. Seen in the direction from the warp thread entry side to the warp thread exit side, the trailing edge of the entry-side guide web is arranged in front of the front edge of the exit-side guide web. In this way, a pull-in opening between the front edge of the one guide web and the trailing edge of the other guide web is provided transversely to the warp direction in the transverse direction.

In the middle section, the webs in warp direction are characterized by very narrow. In order nevertheless to achieve a sufficient lateral guidance of the warp thread, each guide web adjacent to the central portion on both sides in each case an end portion which connects the central portion with the respectively associated thread support surface of the thread eye. The end portions of the guide webs extend in the warp direction along the entire thread support surface, to which they adjoin. The end sections are, as it were, guide lugs for the warp thread, which rise next to the thread support surfaces. In this way, a lateral Kettfadenführung is ensured even if the warp, for example, due to high accelerations or delays of the hive briefly lifts off the thread support surface. The extended in the end sections guide rails also prevent torsion of the heald around its longitudinal axis. When the heddle is in open shed position, this embodiment of the thread eye according to the invention ensures improved lateral guidance of the warp thread. At the same time, however, a sufficiently large intake opening in the transverse direction is created.

According to one embodiment of the invention Heald, the two thread support surfaces, which are arranged opposite one another in the longitudinal direction of the heddle body, each having a first curvature region and a second curvature region whose curvatures are different. Preferably, the curvature of the first and the second curvature region is constant in each case, the amounts of the curvatures of the two curvature regions being different. In particular, the curvature in the first curvature region is greater in magnitude than the curvature in the second curvature region. The first curvature region may be associated with the warp thread entry side of the thread eye and the second curvature region with the warp thread exit side of the thread eye. When the shed is open, there are one or more heald frames in the upper shed or in the lower shed. The warp threads are thereby deflected upwards or downwards starting from the stringing or sub-rods of the weaving machine and enter the thread eye opposite the warp thread plane in the closed shed position or a horizontal plane at a warp thread entry angle and out of the thread eye at a warp thread emergence angle. The warp thread emergence angle is generally greater than the warp thread entry angle. In order to optimize the support of the warp thread in the thread eye along the thread support surface, the warp thread support surface has two curvature regions with different curvatures. In this way it is possible to provide the largest possible contact surface between the warp thread and the thread support surface in order to distribute the load of the warp thread and the thread support surface along as large a contact surface. In this case, a very uniform load of the warp thread can be achieved, in particular at maximum excavation of the shanks, when the warp threads are stretched anyway maximum. The inventive design, the number of Kettfadenbrüche be reduced. The warp thread extends along the entire contact surface always curved on the thread support surface, so that a local overstressing of the warp, for example, at an edge of the thread eye, is avoided. If required, for example in the case of thicker plastic strands, the thread support surface can also have several areas of curvature.

It is also advantageous if the thread support surfaces are curved in the two curvature areas exclusively in the warp direction. The thread support surface is preferably flat in the transverse direction between the two guide webs. In this way, it is avoided that the warp thread jammed in a direction of curvature in the transverse direction tread support surface. The lateral guidance takes place exclusively through the two guide webs.

The length of the curvature region with the smaller curvature, i. larger radius of curvature, may be larger and preferably at least twice as large as the length of the curvature region with the magnitude greater curvature. The length is measured along the surface of the respective curvature region between the warp thread entry side and the warp thread exit side. In this case, the point of the smallest distance between the two opposite thread support surfaces in the curvature region with the smaller magnitude curvature lie. By this configuration, a total of the smallest possible curved thread support surface is formed, which reduces the stress on the warp.

Preferably, the two thread support surfaces of the warp thread entry side to the Kettfadenaustrittsseite curved along its entire extent. It may be sufficient to provide only two areas of curvature with different curvatures. The first curvature region adjoins the warp thread entry side, merges at a transition point into the second curvature region, which extends to the warp thread exit side. It is expedient if a tangent applied to the thread support surface at the transition point extends both tangentially to the curvature of the first curvature region, and tangentially to the curvature of the second curvature region following the transition point. The transition between the two curvature areas is edge and infinitely designed.

The curvature of the first curvature region is advantageously adapted to the warp thread entry angle and the curvature of the second curvature region to the warp thread exit angle. This can be done, for example, such that a contact point is determined for both curvature regions, at which the warp thread in the open shed position, i. maximum excavation, the heald should come into contact with the thread support surface. Starting from this and from the known Kettfadeneintritts- and Kettfadenaustrittswinkel the radius or the curvature of each curvature region can be determined so that the warp thread at the contact points in each case runs tangentially to the thread support surface.

The lateral guide webs are preferably formed such that their thickness in the central portion and in the two end portions is substantially constant. This allows both on the outside of the heald body, as well on the inner side of the guide webs facing the thread eye, a flat surface can be achieved, along which the warp thread can slide.

It is also advantageous if the height of the end sections measured at right angles to the respectively adjacent thread support surface is greater than the diameter of the warp thread. As a result, even a good lateral guidance of the warp thread is achieved even if it loses contact with the thread support surface.

The height of the end portion measured perpendicular to the thread support surface may increase in the warp direction towards the central portion of the guide web. The narrow side of the end portion may extend obliquely to the longitudinal direction of the heddle body. This oblique course can be rectilinear and / or curved and / or curved. If the warp thread guided through the thread eye reaches the narrow side of an end section, then it can slide along there and is finally guided to the thread support surface. Likewise, a warp thread passed between a pair of strands through a heald does not hang on an end portion, but slides along the sloped narrow side and finally disengages from the heald.

In the heddle according to the invention, the thread eye is preferably formed or limited directly by the heddle body. The heald is designed without inserts on the thread eye. In particular, there are no additional bodies, such as Maillons used.

The heddle is preferably made entirely of plastic and thus forms a plastic strand. This can, for example, by casting, injection molding or Injection molding presses are produced. The entire plastic strand is therefore manufactured as one piece. A connection of several items in the manufacturing process is avoided. Plastic strands are characterized by their low mass and corrosion resistance. Therefore, they are preferably used in water jet looms, which can reach very high operating speeds.

The invention relates to a heddle 10, as shown schematically in FIG Fig. 1 is shown. The heddle 10 has at its two ends in each case an end eyelet 11. The end eyelets 11 are used to attach the wire to a heddle support rail, not shown, of a heald 12 of a loom. In about the middle of the heddle body 13 of the heald 10, a thread eye 14 is provided which serves to receive a warp thread 15. Each warp thread 15 is guided by a thread eye 14 of an associated heddle 10 in a warp direction K from a warp thread entry side 16 to a warp thread exit side 17 of the thread eye 14.

To form a shed 20, the heddle shafts 12 are moved in a vertical direction, which corresponds in the position of use of the healds 10 to the longitudinal direction L of the heddle body 13. Depending on the position of the heddle shafts 12, the warp threads 15, which are guided by the thread eyes 14 of the heald 10 arranged on the heald 12, are deflected upwards or downwards starting from a spreading beam or from part bars 21 of the weaving machine. The warp yarns 15 thus led out of the horizontal plane enter the thread eye 14 at a warp thread entry angle α at the warp thread entry side 16 and out of the thread eye 14 at a warp thread exit angle β at the warp thread exit side 17. The warp thread entry angle α and the warp thread exit angle β are respectively measured between the longitudinal central axis A of the warp thread 15 and a horizontal plane E. The warp thread entry angle α and the warp thread exit angle β can be different depending on whether the heald 12 is in the upper shed or in the lower shed. In addition, the warp thread entry angle α and the warp thread exit angle β are different for consecutively arranged heddle shafts 12. The warp thread entry angle α are generally smaller than the Kettfadenaustrittswinkel β, since the distance of the heald frames 12 to the coating tree 21 is greater than the distance of the heddle shafts 12 to a fabric edge 22nd

In order to improve the reception of the warp thread 15 in the thread eye 14, the thread eye 14 has a special shape. In the longitudinal direction L of the heddle body 13, the thread eye 14 is bounded by two spaced apart thread support surfaces 26. In the preferred embodiment, the thread support surfaces 26 along their entire extension direction from the warp thread entry side 16 to the warp thread exit side 17 seen in the warp K direction curved course. By way of example, the curved thread support surface is subdivided into a first curvature region 27 and a second curvature region 28. The curvature in the two curvature regions 27, 28 of the thread support surfaces 26 is constant in the exemplary embodiment described here. This means that the thread support surface 26 extends in the first curvature region 27 along a first radius R1 and in the second curvature region along a second radius R2. The two radii R1, R2 are constant. The first radius R1 is smaller in magnitude than the second radius R2, so that the first curvature 1 / R1 is greater in magnitude than the second curvature 1 / R2. The center of the second radius R2 of the second curvature region 28 is in the embodiment on the longitudinal center plane M, which extends centrally in the region of the thread eye 14 in the longitudinal direction L through the heddle body 13. In the embodiment, the two opposite thread support surfaces 26 approximately at the central longitudinal axis M to the smallest distance. The location of the smallest distance is in the second curvature region 28 with the lower curvature.

In the FIGS. 4 and 6 It can be seen that the first curvature region 27 begins directly at the warp thread entry side 16 of the thread eye 14. Its first radius R1 or its first curvature 1 / R1 is adapted to the warp thread entry angle α. For this purpose, the curvature in the first curvature region 27 is selected such that a tangent to the contact point at which the warp thread 15 comes into contact with the thread support surface 26 in the first curvature region 27 encloses an angle with the horizontal plane E, the amount with the warp thread entry angle α corresponds to web shaft 12 located in the upper compartment or in the lower compartment. The center of the first radius R1 of the first curvature region 27 is located between the warp thread entry side 16 and the longitudinal center plane M of the heddle body 13.

The length of the section of the thread support surface 26 in the second curvature region 28 is significantly smaller than the length of the section of the thread support surface 26 in the first curvature region 27. At a transition point 30, the two sections of the thread support surface 26 steplessly and without edges from the first curvature region 27 in the second curvature region 28th above. A tangent applied to the thread support surface 26 at the transition point 30 extends tangentially to the two ends of the thread support surface section 26 in the first curvature region 27 and in the second curvature region 28.

In the embodiment, only two curvature regions 27, 28 are provided. It is understood that in a modification to the described embodiment, also further curved areas may be present, for example, to create at the transition point 30 between the first adjoining the Kettfadeneintrittsseite 16 curvature region 27 and adjoining the Kettfadenaustrittsseite 17 second curvature region 28 an edge and stepless transition.

As in Fig. 3 schematically illustrated, the warp thread entry angle α and the warp thread exit angle β may vary depending on the position of the heald 12 in the warp direction K and depending on whether the corresponding heald 12 is in the upper shed or lower shed. By way of example, warp thread entry angles α1 and α2 and warp thread exit angles β1 and β2 are entered there. In order to achieve optimum adaptation of the healds 10 to the course of the warp threads 15, warp thread entry angle ranges and warp thread emergence angle ranges can be determined and the curvature of the respective thread support surfaces 26 in the first curvature region 27 and in the second curvature region 28 adapted to the respective associated angular region. For heddle shafts 12, which are assigned to different angular ranges, healds with differently curved thread support surfaces 26 can then be provided. This can be useful, for example, when weaving machines are used with many heald frames. For simple binding types, the warp thread entry angles and the warp thread exit angles of the individual heald frames 12 differ only within a permissible angle range, so that the healds 10 used can be identical. For example, angle ranges can be set with a difference of about 5 to 10 degrees for the warp thread entry angle α and for the warp thread exit angle β for which the same heald 10 can be used.

If the warp thread entry angles deviate very strongly from one another in the upper shed position and the lower shed position, the curvatures of the two yarn support surfaces 26 of the heald 10 can be chosen differently. Preferably, however, the two thread support surfaces 26 of the thread eye 14 of the heald 10 are designed symmetrically.

In a transverse direction Q transverse to the longitudinal direction L of the heddle body 13 and transversely to the warp direction K, the thread eye 14 is delimited by an entry-side guide web 33 and an exit-side guide web 34. The two guide webs 33, 34 are arranged in the transverse direction Q with a transverse distance x. The transverse distance x defines the width or the clear width of the thread eye 14 in the transverse direction Q. The thread eyes 14 remote from the outer surfaces 35 of the two guide webs 33, 34 form with the adjoining outer surface of the other strand body 13, a seamless planar outer surface. The thread eye 14 facing inner surfaces 36 of the two guide webs 33, 34 are executed level and edged flat.

Each guide web 33, 34 has a central portion 37, on each of which an end portion 38 connects to both sides. The two end sections 38 of a guide web 33, 34 each adjoin one of the two thread support surfaces 26. The end portions 38 are dependent on the respectively associated thread support surface 26.

The exit-side guide web 34 has a Leading edge 38, which is associated with the warp thread entry side 16. The entry-side guide web 33 has a trailing edge 40 which is assigned to the warp thread exit side 17. The leading edge 39 and the trailing edge 40 are arranged in the warp direction K at a pull-in distance y. The leading edge 39 and the trailing edge 40 are substantially parallel to each other. The pull-in distance y is greater than the transverse distance x. For retraction of the warp thread 15 in the thread eye 14 of the transverse distance x is usually not sufficient. Therefore, the two guide webs 33, 34 in the region of their central portions 37 on a pull-in distance y formed pull-in, so that the Einziehnadel with the warp 15 transverse to the warp K in the transverse direction Q or obliquely thereto between the two guide webs 33, 34 are passed can.

In the middle sections 37, the two guide webs 33, 34 have a constant width in warp direction K. The width of the guide webs 33, 34 increases in the end portions 38 of the guide webs 33, 34 to the respective thread support surface 26 toward. The end portions 38 extend along the entire thread support surface 26, to which they adjoin. In this way, a lateral guidance of the warp thread 15 is independent of the width of the guide webs 33, 34 ensures in the middle section 37 in the area of the thread support surface 26. The height of the end portions 38, measured at right angles to the thread support surface 26 corresponds in the embodiment at least the diameter of the warp thread 15, but can also be chosen to be larger, for example, at least twice as large as the diameter of the warp thread 15. Thus, the lateral guidance of the warp thread 15th be improved, even if it moves away from the thread support surface 26, for example, in a strong delay or Acceleration of the heald 12 during operation of the loom.

The leading edge 39 and the trailing edge 40 of the middle sections 37 of the guide sections pass on either side into a narrow side 41 of the respective end section 38. The leading edge 39, the trailing edge 40 and the narrow sides 41 may have edges at the transitions to the outer surface 35 or the inner surface 36 or may be rounded without edges.

The narrow side 41 extends obliquely with respect to the longitudinal direction L and the warp direction K. The distance between two opposite narrow sides 41 of the entry-side guide web 33 and the exit-side guide web 34 thus increases starting from the respective middle section 37 to the warp thread entry side 16 or to the warp thread exit side 17. Through these oblique narrow sides 41 of the end portions 38, a warp thread 15, which passes through a displacement in the transverse direction Q in contact with the narrow side 41 with a continued movement of the heald 10 in the longitudinal direction L to the respective thread support surface 26 derived. The slope of the narrow sides 41 ensures that a warp thread 15 resting thereon slides along on the narrow side 41 and finally slips off the end section 38 and comes to lie on the thread support surface 26.

The same applies to warp threads which are passed between two adjacent healds 10 and accidentally come into contact in a narrow side 41 of an end portion 38 by a lateral displacement. Such warp threads also slide along the oblique narrow sides 41 until they finally reach the end sections 38 slide down without getting caught with the heald 10 permanently.

The oblique narrow side 41 of an end portion 38 may be straight or have a single or multiple curved course.

In a modification of the embodiments according to the FIGS. 4 to 6 are in the in the FIGS. 7 and 8 illustrated embodiments, the thread support surfaces 26 in Kettfadenrichtung K essentially flat and executed without curvature. In all embodiments, the thread support surface 26 is designed without curvature in the transverse direction Q. The lateral guidance of the warp threads 15 is ensured by the end sections 38 of the guide webs 33, 34.

The invention relates to a heddle 10 with a thread eye 14, which can be designed as a plastic strand and can be made in one piece from a plastic material. The heald 10 has a thread eye 14 for receiving a warp thread 15. In the longitudinal direction L of the heddle body 13, the thread eye 14 is bounded by two opposing thread support surfaces 26. The thread support surfaces 26 may extend in a configuration according to the invention of the heddle 10 from a warp thread entry side 16 to a warp thread exit side 17 of the thread eye 14 curved. The curvature is greater in a first curvature region 27 following the warp thread entry side 16 than in a second curvature region 28 subsequent to the warp thread exit side 17. In transverse direction Q transverse to the warp direction K and transversely to the longitudinal direction L, the thread eye 14 by two guide webs 33, 34th limited.

Their end portions 38 may extend in a further form of heald 10 on both sides of the thread support surfaces 26 along the entire extent of the warp thread entry side 16 to the warp thread exit side 17. In a middle section, the two guide webs 33, 34 are arranged in warp direction K to form a pull-in opening with pull-in distance y. The design of the guide webs 33, 34 and the configuration of the thread support surfaces 26 can be realized independently of each other or in combination with each other in a heald 10.
