Description

[Technical Field]

[0001] Two immediately adjacent slats of the reed define a gap through which one warp thread is guided. The distance and direction of the slats are important for producing a uniform fabric. [Background technology]

[0002] In the reed known from DE 10 05 04 14 A1, the ends of the slats are thicker than the intermediate sections, allowing the slats to abut against each other at the ends. The ends have through holes and are pressed against the retaining rails. At the ends, the slats can be adhesively connected to each other with an adhesive.

[0003] The application and curing of adhesive and the resulting forces can cause the reed to deform during manufacture, which is undesirable.

[0004] Patent Document 2 discloses a reed for a high-speed loom. A DLC coating is applied to the slats of the reed. DLC stands for "diamond-like carbon." In this way, wear of the slats is reduced and their lifespan is extended.

[0005] Patent document 3 discloses a reed for a loom that operates quietly. It has a box-like shape with an inner section connected to it. Metallic or composite materials can be used as the material.

[0006] Patent document 4 describes a backrest for a weaving machine having thread deflection elements supported at multiple points, the low-mass thread deflection elements being configured to minimize the mass of the vibrating part of the backrest. The thread deflection elements can be made of lightweight plastic or fiber-reinforced composites. [Prior art documents] [Patent documents]

[0007] [Patent Document 1] U.S. Patent No. 4,529,014 [Patent Document 2] European Patent Application Publication No. 550752 [Patent Document 3] European Patent No. 1170409 [Patent Document 4] German Patent Application Publication No. 102006061376 Summary of the Invention [Problem to be solved by the invention]

[0008] SUMMARY OF THE INVENTION It is an object of the present invention to provide a reed for a loom in which the reed slats are uniformly arranged and oriented. [Means for solving the problem]

[0009] This object is solved by a reed having the technical features set forth in claim 1.

[0010] The reed has a number of slats (thin iron plates, reed fins) extending in an elongated direction between an upper end and an opposite lower end. In a transverse direction perpendicular to the elongated direction, the slats are spaced apart from one another. Two immediately adjacent slats define a gap between them through which each warp thread is guided during weaving.

[0011] The upper end of each slat is attached to an upper support shaft. The lower end of each slat is attached to a lower support shaft. The slats are attached to the support shafts by adhesive bonding. As a result, the slats are connected to each other at their ends and to their respective corresponding support shafts.

[0012] Each support shaft has two plate portions extending transversely and not directly abutting each other. The plate portions are arranged at a distance in the longitudinal direction on opposing sides of the upper end or lower end of the slat. The upper end of the slat is held between the two plate portions of the upper support shaft, and the lower end of the slat is held between the two plate portions of the lower support shaft. The longitudinal direction is perpendicular to the transverse direction and perpendicular to the extension direction.

[0013] To align the slats as precisely as possible along a straight line in the transverse direction, the plates are manufactured from a fiber-reinforced composite material. The reinforcing fibers can be carbon and / or glass and / or other plastic and / or natural fibers embedded in the plastic matrix of the composite material. This has proven to ensure that the adhesive bond is formed while maintaining the orientation of the slats and the support shafts along straight lines parallel to the transverse direction Q. Plates made from composite material exhibit no or very little warping during the reed's manufacture, especially during the adhesive's curing, and their straightness is significantly improved compared to plates or support shafts made from other materials, such as metal. At the same time, the mass of the support shafts or plates can be significantly reduced, simplifying the reed's acceleration upon impact with the selvedge.

[0014] Advantageously, the plate extends continuously in the transverse direction along all slats of the reed. This plate extends along substantially the entire width of the reed in the transverse direction Q and is formed integrally without any seams or joints in the transverse direction Q. Furthermore, parallel to the extension direction, several plate sections can be arranged adjacent to each other on the upper and / or lower support shafts. However, it is preferred to arrange exactly two plate sections on each of the upper and lower support shafts so that each plate section forms a pair of plates.

[0015] The upper support shaft preferably has a lid arranged adjacent to the upper end of the slat in the extension direction. This lid can be in direct or indirect contact with the two plate parts. The lid of the upper support shaft can be connected to the upper end of the slat and the plate part of the upper support shaft by an adhesive bond. The lid is preferably made of a fiber-reinforced composite material and is manufactured from the same material as the plate parts. Together with the plate parts, the lid part defines a rectangular or square space in cross section and can be positioned at the upper end of the slat to form an adhesive bond.

[0016] Preferably, the lid extends continuously along all the slats in the transverse direction. The lid is formed integrally without seams or joints in the transverse direction. Preferably, the upper support shaft comprises one lid.

[0017] The lower support shaft can be provided with a reinforcing rod, in particular a square reinforcing rod arranged adjacent to the lower end of the slat in the extension direction. The square reinforcing rod is arranged between the plates of the lower support shaft. It is preferably connected to the lower end of the slat and the plate of the lower support shaft by adhesive bonding. The square reinforcing rod preferably extends continuously in the transverse direction along all slats of the reed. It is formed integrally without seams or joints in the transverse direction. Preferably, the lower support shaft is provided with one reinforcing rod.

[0018] The slats can be connected to one another by means of a connecting arrangement at the upper and / or lower support shaft. This connecting arrangement serves to connect the slats to one another, particularly during the manufacture of the reed, and simplifies the process until the adhesive for the adhesive bond has hardened. In a preferred embodiment, the connecting arrangement comprises two connecting rods extending transversely at the upper and / or lower support shafts, respectively. Each connecting rod can be configured as a semicircular rod with a semicircular cross section. The connecting rods are connected to one another by a bendable binding element, for example a metal wire. For this purpose, the binding element forms a plurality of loops. Each loop is wrapped around the connecting rod and guided into and through the gap between the two slats.

[0019] Each connecting arrangement comprises two connecting rods, and the bendable binding element is preferably arranged between the plates of the upper support shaft or between the plates of the lower support shaft. It is therefore particularly advantageous if, viewed in the longitudinal direction, each connecting rod is arranged between the slat and the immediately adjacent plate of each upper support shaft or each lower support shaft. To this end, transversely extending recesses can be arranged in each plate of the upper support shaft and / or the lower support shaft to accommodate one connecting rod each. These recesses are open on the side facing the slats and are in particular groove- or valley-shaped. The cross-sectional shape of these recesses preferably corresponds to the cross-sectional shape of the connecting rods to be accommodated therein. For example, recesses with a semicircular cross section can be provided to accommodate connecting rods with a semicircular cross section.

[0020] This recess allows the plates to be positioned very close to the upper or lower ends of the slats. The plates cover the connecting rods, eliminating the need for separate adhesive joints to cover the connecting rods. The connecting rods are secured together by the adhesive bond used to connect the plates to the adjacent ends of the slats.

[0021] In a preferred embodiment, at least one spacer is arranged in the region of the upper support shaft and / or at least one spacer is arranged in the region of the lower support shaft, each spacer comprising a plurality of spacer elements each located in one gap between two immediately adjacent slats.

[0022] In one embodiment, each spacer is formed by a helical spring having a plurality of windings, such that one winding can form a spacer element and can be positioned in the gap between two immediately adjacent slats. The helical spring is preferably positioned under tension.

[0023] Advantageously, at least one spacer is provided longitudinally between the plates of the upper holding shaft or the plates of the lower holding shaft, whereby the at least one spacer is covered by the plates and fixed, preferably by adhesive bonding.

[0024] In one embodiment, some or all of the slats are provided with spacer studs. These spacer studs can be provided on the slats in the region of the upper and / or lower support axis. These spacer studs project away from the slats in the transverse direction. They can serve to maintain a minimum distance between two immediately adjacent slats. Spacer studs can be located on all or some of the slats.

[0025] Preferred embodiments of the reed according to the invention are set out in the dependent claims, the detailed description and the drawings. In the following, preferred embodiments of the reed are explained in detail on the basis of the attached drawings, in which: [Brief explanation of the drawings]

[Figure 2] 1 is a highly schematic front view of a reed for a loom; [Figure 3] FIG. 1 is a side view of a transversely curved slat.

[Figure 6] 1 is a schematic cross-sectional view of a prior art reed; [Figure 7] 1 is a schematic cross-sectional view of a reed according to an embodiment of the present invention. [Figure 8] FIG. 8 is an enlarged view of a range A of the reed in FIG. 7. [Figure 9] 10 is a schematic cross-sectional view of a further embodiment of the reed of the present invention including a modified embodiment of one or more slats with spacer studs. FIG. DETAILED DESCRIPTION OF THE INVENTION

[0027] FIG. 1 shows a schematic diagram of a loom 10. Starting from a backrest 11, warp threads 12 each extend through a heddle (not shown) on one of a number of heddle frames 13. The heddle frame 13 can be moved vertically upward or downward to form a shed. At the warp exit side of the heddle frame 13, the warp threads 12 extend to a selvedge 14. A weft thread 15 can be inserted into the shed opened by the heddle frame 13 in front of the selvedge 14. A reed 16 allows the inserted weft thread 15 to be driven into the selvedge 14. For this purpose, the reed 16 can be moved, in particular rotated, to drive the weft thread into the selvedge 14. FIG. 1 shows the driving position of the reed 16 in solid lines, while the retracted position of the reed 16 away from the selvedge 14 in dashed lines.

[0028] The reed 16 includes a plurality of slats (narrow iron plates, reed blades) 20. Each slat 20 extends in an extension direction R from an upper end 21 to a lower end 22. The upper end 21 of the slat 20 is attached to an upper support shaft 23, while the lower end 22 is attached to a lower support shaft 24. In a transverse direction Q perpendicular to the extension direction R, the slats 20 are uniformly spaced apart from one another, so that two immediately adjacent slats 20 define a gap 25. The warp yarns 12 can be guided through the gap 25. The transverse direction Q substantially corresponds to the weft direction, in which the weft yarns 15 are inserted into the shed. At least during weaving at the selvedge 14, the extension direction R of the slats 20 is substantially vertical at the weaving position. For example, as can be seen from FIG. 3, each slat has a leading edge 26 and a trailing edge 27 opposite the leading edge 26 in the longitudinal direction L. The longitudinal direction L is perpendicular to the extension direction R and perpendicular to the transverse direction Q. Each slat 20 has two side surfaces 28 that are on opposite sides in the transverse direction Q. The side surfaces 28 of two immediately adjacent slats 20 define a gap 25.

[0029] In an embodiment, the leading edge 26 and the trailing edge 27 of each slat 20 may extend parallel to one another, e.g., linearly. Alternatively, the leading edge 26 and / or the trailing edge 27 may extend non-linearly. For example, a recess may be provided at the location of each leading edge 26 to form an air channel extending in the transverse direction Q. This air channel allows the introduction of the weft yarn by an air nozzle.

[0030] It is important for a uniform weave that the distance between the slats 20 in the transverse direction Q, and therefore the width of the gaps 25, are everywhere the same, while their leading edges 26, at least outside any recesses therein that may be provided to form air channels, lie in a common plane oriented perpendicular to the longitudinal direction. Figures 3 and 4 show diagrammatically that curvature or irregular deformation of the upper and / or lower support shafts 23, 24 may occur during the manufacture of the reed 16, in particular due to the adhesive bond between the support shafts 23, 24 and the slats 20, so that the leading edges 26 no longer lie in a common plane.

[0031] Undesirable deformation of the retaining shafts 23, 24, which may occur with the prior art, must be avoided.

[0032] 7 is a schematic cross-sectional view of a reed 16 according to an embodiment of the present invention. The upper support shaft 23 has two upper plate portions 32, which are spaced apart in the longitudinal direction L, with the upper ends 21 of the slats 20 positioned therebetween. The upper plate portion 32 extends along all of the upper ends 21 of the slats 20 in the transverse direction Q and is integrally formed without any seams or joints. The upper plate portion 32 is made of a fiber-reinforced composite material. The reinforcing fibers may be carbon or glass fibers embedded in a plastic matrix.

[0033] In this embodiment, the upper support shaft 23 further comprises a lid 33. Furthermore, the lid 33 is preferably made of a fiber-reinforced composite material, e.g., the same material as the upper plate 32. The lid 33 is arranged adjacent to the upper end 21 of the slat 20 when viewed in the extension direction R. The lid 33 extends along, preferably along the entire upper end 21 of the slat 20 in the transverse direction Q and is integrally formed without any seams or joints. The lid 33 and the two upper plate 32 define a rectangular cross-sectional space for receiving adhesive K. The adhesive K connects the upper end 21, the upper plate 32, and the lid 33 of the slat 20 to one another by adhesive bonding. In the region of the upper end 21, the adhesive K further penetrates between the slats 20 and forms a hemispherical, convex, outwardly extending end surface 34 on the side facing the lid 33. The end surface 34 can be disposed in the region between the upper plate portions 32, and preferably does not protrude in the extension direction R from the region between the upper plate portions 32.

[0034] In order to determine the position and orientation of the slats 20 relative to one another before the adhesive K hardens, connecting arrangements 35 are present at the upper ends 21 of the slats 20. Connecting rods 36 extending parallel to one another in the transverse direction Q are part of the connecting arrangements 35. In the exemplary embodiment, each connecting rod 36 is configured as a semicircular rod with a semicircular cross section. One connecting rod 36 abuts against the leading edge 26, and each of the other connecting rods 36 abuts against the trailing edge 27 of the upper end 21 of the slat 20. For each connecting rod 36, a recess 37 is provided in the adjacent upper plate 32, which is open toward the leading edge 26 or the trailing edge 27 of the slat 20. The recess 37 and the upper plate 32 are groove-shaped. In the exemplary embodiment, the recess 37 matches in cross section the shape of the connecting rod 36 located therein and is also configured semicircular.

[0035] A flexible bundling element 38, for example a copper wire made of a metallic material, is also part of the connecting arrangement 35. The bundling element 38 connects the connecting rods 36 of the connecting arrangement 35 in such a way that it forms a plurality of loops 39. One or at least one loop 39 is guided around two connecting rods 36 and through one gap 25 between two immediately adjacent slats 20. In this way, at least a preliminary connection or fastening of the slats 20 is achieved.

[0036] The lower support shaft 24 of the reed 16 comprises two lower plate parts 43 arranged at a distance from each other in the longitudinal direction L, which, like the upper support shaft 23, extend along all of the lower ends 22 of the slats 20 in the transverse direction Q, with the lower ends 22 of the slats 20 located between them. The lower plate parts 43 are constructed integrally without seams or joints and are made of a fiber-reinforced composite material, like the upper plate part 32. The dimension of the lower plate part 43 in the extension direction R may differ from the dimension of the upper plate part 32 in the extension direction R.

[0037] In this embodiment, the lower support shaft 24 is provided with a reinforcing rod 44 configured as a square rod instead of the lid 33. The reinforcing rod 44 extends along all lower ends 22 of the slats 20 in the transverse direction Q and is arranged adjacent to the lower ends 22 in the extension direction R. The reinforcing rod 44 is arranged between the lower plate parts 43 when viewed in the longitudinal direction L. By means of an adhesive K introduced between the lower plate parts 43, the lower plate parts 43, the reinforcing rod 44 and the lower ends 22 of the slats 20 are connected to one another by an adhesive bond. At the end of the lower plate part 43 facing the upper support shaft 23, the adhesive K also forms the end face 34.

[0038] In the region of the lower retaining shaft 24, there is also a connecting arrangement 35 identical to the connecting arrangement 35 of the upper retaining shaft 23 for connecting the slats 20. Similar to the upper plate parts 32, the lower plate parts 43 each have a recess 37 for receiving a connecting rod 36 of the connecting arrangement 35 therein. For the detailed arrangement and configuration of the connecting arrangement 35 in the region of the lower retaining shaft 24 or lower end 22, reference is made to the description of the connecting arrangement 35 at the upper retaining shaft 23.

[0039] The plate portions 32, 43 substantially terminate on their respective sides facing each other with a connecting arrangement 35 disposed thereon. The plate portion 32 extends slightly beyond the connecting arrangement 35 toward the respective other retaining shaft 24 or 23. Each plate portion 32, 43 of the retaining shaft 24 or 23 has a surface 45 facing the respective other retaining shaft 24 or 23 in the extension direction R. For example, the surface 45 of the lower plate portion 43 is disposed opposite the surface 45 of the upper plate portion 32 in the extension direction R.

[0040] The recesses 37 of the plates 32, 43 are located near the faces 45 of each plate 32, 43, respectively. Between the faces 45 and the recesses 37, each plate 32, 43 has a web face 46 with a low height H in the extension direction R. The web face 46 faces either the leading edge 26 or the trailing edge 27 of the slat 20, depending on the position of the plate 32, 43. In an embodiment, the height H of the web face 46 is at most 2 mm or at most 3 mm.

[0041] In one embodiment, the adhesive K in contact with the two upper plates 32 or the two lower plates 43 forms an outer, hemispherical, convex edge 34 between the opposing plates 32, 43. In this way, the formation of larger pockets in which fibers and other contaminants (debris) can accumulate is prevented.

[0042] The area A shown in Figure 7 is enlarged in Figure 8. The height H of the web surface 46 is shown as an example for the lower plate portion 43. This configuration is similar for all plate portions 32, 43 of the reed 16.

[0043] In the embodiment of FIG. 7, at least one spacer 50, and in the embodiment two spacers 50, are disposed at the upper end 21 between the two upper plates 32 and at the lower end 22 between the lower plates 43. Each spacer 50 comprises a plurality of spacer elements, one spacer element disposed in each gap 25 between two immediately adjacent slats 20. In the embodiment, each spacer 50 is a helical spring, with exactly one winding of the helical spring being a spacer element. The helical spring can be disposed in tension at the upper end 21 and the lower end 22 of the slat 20. The copper wire of the helical spring can be threaded through a glued seam between the leading edge 26 and the adjacent plate 32, 43 or between the trailing edge 27 and the adjacent plate 32, 43. The strength of the copper wire of the helical spring is typically slightly lower than the gap 25 and can be up to 35 μm, compared to 20 μm for the filigree reed 16 in the embodiment. A rougher reed would allow for a stronger copper wire. If the strength of the copper wire in the spiral spring is such a small value, there is no need to provide recesses in the leading edge 26 or trailing edge 27 of the slat 20 or in the plate portions 32, 43.

[0044] As shown in the figure, the spacers 50 are arranged between the upper plate portions 32 of the upper retaining shaft 23 or between the lower plate portions 43 of the lower retaining shaft 24 when viewed in the longitudinal direction L, and are later integrated by an adhesive bond formed with adhesive K.

[0045] In addition to or as an alternative to the spacers 50, one or more slats 20 may be provided with spacer studs 51 projecting from one or both side surfaces 28. The spacer studs 51 are located in the region of the upper end 21 or lower end 22 of the slats 20 (FIG. 9). The spacer studs 51 define the minimum distance between two immediately adjacent slats 20. A portion of a slat 20 with spacer studs 51 is shown in FIG. 5. The spacer studs 51 may be formed by stamping so that they project from one side surface 28, while a recess 52 is formed in the opposing side surface 28. The recess 52 or spacer stud 51 may thus comprise a conical ring portion 53 whose center forms a central projection 54. The central projection 54 is offset from the surface of the conical ring portion 53.

[0046] For comparison with the embodiment of the present invention shown in Figures 7-9, a prior art reed 16 is shown in Figure 6. In this embodiment, the plates 32, 43, the cover 33, and the reinforcing rod 44 are made of metal and steel. Especially in very wide reeds 16, bowing of the support shafts 23, 24 occurs in the transverse direction Q, as shown in Figures 3 and 4. In the prior art, the plates 32, 43 are made of steel and are typically not ideally straight in the transverse direction Q. During the manufacture of the support shafts 23, 24, and especially during the manufacture of the connection with adhesive K, the plates 32, 43 are clamped to the device and are therefore approximately straight in the transverse direction Q. This generates internal stresses in the plates 32, 43. These internal stresses cause bending, warping, and deformation of the support shafts 23, 24 when they are removed from the device after the adhesive K has hardened. As a result, the slats 20 of the reed 16 are no longer ideally oriented in the transverse direction Q. If the slats 20 are to be brought into contact with a plane that straddles the transverse direction Q and the extension direction R, not all of the leading edges 26 will contact this plane, but some of the leading edges 26 will be spaced apart from this plane. A reed 16 that is warped in this manner is undesirable.

[0047] This warping is avoided in the present invention because the plates 32, 43 are made of a fiber-reinforced composite material and are already oriented in a nearly ideally straight line in the transverse direction Q before the adhesive bond is formed.

[0048] FIG. 6 also shows that the connecting arrangement 35 is not arranged between the plates 32, 43 in the region of the retaining shafts 23, 24, but is arranged adjacent to the plates 32, 43, in the extension direction R, adjacent to each of the faces 45 in the embodiment. There, additional inner spacers 50i are also arranged and configured as helical springs. Because the connecting arrangement 35 and the inner spacers 50i are arranged outside the retaining shafts 23, 24, seams 55 must be provided adjacent to the faces 45 of the adhesive plates 32, 43 to cover and secure the connecting arrangement 35 or the inner spacers 50i. In this arrangement, the adhesive K forms pocket-like depressions 56 in the region of the connecting arrangement 35 and the inner spacers 50i during hardening, in which fibers and other contaminants can accumulate. If these fall onto the fabric during beating with the reed 16, the contaminants may become trapped in the fabric, potentially rendering the fabric unusable. 7 to 9, the pocket-like recesses 56 are not formed when the adhesive K hardens.

[0049] The recess 37 and adjacent web surface 46 may also be present in the plate portions 32, 43 even if the connecting rod 36 or other component of the connecting arrangement 35 is not located therein. In such a configuration, the recess 37 and web surface 46 may function to adjust the flow behavior and molding of the adhesive K as it hardens, without the need to place a component in the recess.

[0050] The present invention relates to a reed 16 having a plurality of slats 20 spaced apart from one another in a transverse direction Q. Each slat 20 extends from an upper end 21 to a lower end 22. The upper end 21 is connected to two upper plate portions 32 of an upper support shaft 23 by adhesive bonding with adhesive K. The lower end 22 of each slat 20 is connected to two lower plate portions 43 of a lower support shaft 24 by adhesive bonding with adhesive K. These plate portions 32, 43 are each made of a fiber-reinforced composite material. Preferably, the entire upper support shaft 23 and the entire lower support shaft 24 are made of parts made of fiber-reinforced composite material. [Explanation of symbols]
