Definitions

  • the present invention relates to an arrangement on a weaving loom for the actuation or control of reed dents or teeth, which extend through the shed, having a bearing spindle extending parallel to the direction of movement of the shuttle through the shed, said reed teeth being arranged along the length of the spindle and being individually pivotal about the spindle, and means for preventing lateral bending of the reed teeth.
  • this invention contemplates an arrangement on a weaving loom in which the reed teeth lamellae are arranged between guide elements of laminar design to prevent lateral bending thereof.
  • FIGURE 1 shows an arrangement according to the invention, in its position on the loom, in perspective view
  • FIGURE 2 shows the arrangement according to the invention, in an enlarged perspective view of an end portion showing details of construction
  • FIGURE 3 shows a section taken along the dot-dash line III-III of FIGURE 2, and
  • FIGURE 4 shows another embodiment of the arrangement in elevation corresponding to a section that would be taken along the dot-dash line IVIV of FIGURE 2.
  • the loom shown in perspective in FIGURE 1 has the warp beam 11.
  • the warp threads 12 extend from the beam over the direction-reversing rollers 13 and 14 and a warp stop motion 15 and about a shed compensating roller 16.
  • the warp threads 12 are, immediately after passing the shed compensating roller 16, subjected to shed formation; an open shed being provided at the point of each shuttle 18 and shed shifting taking place between every two adjacent shuttles 18. This position of the material is indicated in the drawings by an appropriate hatching.
  • the shed formed by the horizontal shafts (not shown) is designated by the reference numeral 17.
  • the shuttles are moved forwards by the dent lamellae 19 (see also FIGURE 2).
  • the lamellae serve also for the beating up of the weft threads inserted against the cloth beat-up 60.
  • the guiding of the shuttles 18 in the shed 17 is effected by means of the warp threads 12.
  • the lamellae 19 are built into the arrangement or apparatus 20 whereof the part 28 is fast on the loom frame 29.
  • the arrangement 20 is further shown in detail in FIG- URE 2.
  • the dent lamellae 19 For producing the movement of the dent lamellae 19, there are two worm shafts 21 and 22. When the worm shafts 21, 22 rotate, the dent lamellae 19 are pivoted in such manner that each lamella 19 lags behind the one arranged after it by a small amount. In this way the entirety of the lamellae forms a wave movement which propagates from the right (in FIGURE 1) towards the left and by means of which the shuttles 18 are entrained.
  • the woven cloth 23 is wound up on the cloth beam 26 over the take-up roller 24 and the pressing-on roller 25.
  • Reference numeral 27 diagrammatically indicates a templet.
  • FIGURE 2 of the arrangement 20 again shows the lamellae 19, the worms 21 and 22 and the fixed machine element 28.
  • guide elements 30 arranged in such manner that a guide element 30 is arranged on both sides of each dent lamella 19. This is shown by way of example for the dent lamella 19a, wherein the guide element 30a is disposed on one side and the guide element 30b on the other side.
  • the dent lamellae 19 are pivotal about the pivot 48 which is common to all of them.
  • the guide elements 30 are formed with apertures through which rods 31, 32, 33 and 34 are transversely drawn.
  • These rods serve for retaining the guide elements 30 and connect the entirety thereof to constitute an assembly of guide elements.
  • the individual elements 30 are furthermore retained with precisely predetermined mutual spacing by spacing elements 35.
  • the spacing elements 35 are, in this example, formed by spiral wires, as shown with reference to the rod 31. This rod has the wire spiral 35 wound about it.
  • the two worm shafts 21 and 22 are pivotally mounted on the metal element 36.
  • the element 36 on the other hand, is secured by screws 37 (of which only one is shown) in releasable fashion on the machine part 28.
  • the guide elements 30 are formed in the forward and upper portion with a recess 38 by which they may be fitted over the projection 39 on the machine part 28.
  • For securing the guide elements 30 to the part 28 in situ (38, 39) use is made of the rail 40, the entire length of which is not shown and which can be clamped fast by readily releasable winged screws, only one of which, 41, is shown.
  • FIGURE 3 In order to secure the guide elements 30, at their rear end, to the machine part 28, an assembly is provided which, in order that it may more readily be understood, is further shown in FIGURE 3 as a section taken along the line III-III of FIGURE 2.
  • the guide elements 30 are, at the position of this cross-section, held together by the rod 34.
  • the spiral wire 42 is provided about the rod as a spacing member.
  • Another rail 44 is secured to the machine part 28 by means of readily releasable wing screws, of which only one screw 43 is shown in FIGURE 2.
  • the rail 44 carries, by means of the screws 45, the carrier members 46, each of which is, for example, shaped as a cube. Formed in each of the elements 46 is a bore and a rod 47 extends through the bores.
  • the guide elements 30, which are disposed at the position of the carrier members 46, are so punched-out that from the rear and from below they extend only as far as the carrier members 46. (As already mentioned, the guide elements 30 are connected by the rods 31 to 34 to form an entire assembly.)
  • the remaining guide elements 30, that is, those positioned between carriers 46, are, however, so dimensioned that they extend over or beyond the zones located laterally of the carriers 46 and thus reach as far as the rail 44 (note FIGURE 4). These elements are therefore also retained by the rod 47 mounted in carriers 46. In this way, the assembly of the guide elements is supported by the rod 47 and the rod is supported by the carriers 46.
  • the carriers 46 are, on the other hand, secured by the screws 45 to the rail 44 and the rail is secured by the wing screws 43 to the fixed machine part 28.
  • the entire arrangement or the assembly of guide elements 30 is thus secured by the screws, in readily releasable manner, to the machine part 28.
  • the guide elements 30 are provided.
  • the spacing elements 35 and 42 and of the spacing elements (not shown) about the rods 32 and 33 the result is achieved that the spacing between the adjacent guide elements 30 is greater by a minimum amount than the thickness of the dent lamellae 19. In this way, the free movability of the lamellae 19 is maintained and they are protected against lateral bending.
  • each dent lamella 19 is disposed between two guide elements 30, then the supplementary advantage is achieved that the adjacent lamellae are not able to adhere together. With adhesion of this kind, there is a danger that lamellae may, during their movement, draw with or entrain the adjacent lamellae and in this way detrimentally influence the accuracy of the wave movement of the lamellae 19 and therewith the calm movement of the shuttle 18.
  • the guide elements 30 are first connected with the rail 44 by the screw 45. Then, the slots 38 are pushed over the projection 39. In this position, the assembly may be suspended from the projection 39, in which case it would not be in the horizontal position shown but would hang downwardly. For the purpose of securing the assembly, it is then pressed against the fixed machine part 28 at the position of the rail 44. In this way, the wing screws 43 may then be inserted. As a further step, the rail 40 is placed in position and is secured to the fixed part 28 by the wing screws 41.
  • the following procedure is used for the insertion of the individual dent lamellae 19: 'First, positioning rods are pushed through the apertures 50, 51 and 52. Then, the dent lamellae 19 are pushed in between the guide elements and are so pressed-on that they bear against the rods 50, 51 and 52. In this way, the apertures in the lamellae 19 are positioned in a straight line for the hearing spindle 48, so that the bearing spindle 48 can be drawn through. Then, the positioning rods 50, 51 and 52 can be taken out.
  • the spiral 35 is pressed-in at the position of the corresponding rod, for example the rod 31, between the guide elements 30.
  • the rod 31 is pushed forwardly somewhat and, simultaneously with the further pushingforward of the rod 31, the spiral 35 is pressed in further between the elements 30. Correction of the spiral 35 parallel to the edges of the guide elements 30 is therefore quite readily possible.
  • FIGURE 4 shows a further embodiment of the guide elements 30.
  • This figure constitutes an elevational view corresponding to a cross'section of the embodiment at the position of the dot-dash line IVIV of FIGURE 2.
  • the dent lamellae 19 is shown in full lines in its yarn beating-up position. It is pressed into this position by the worm shafts 21, 22. Shown in broken lines is the dent lamella 19, constituting the other extreme position of the dent lamella 19.
  • FIGURE 4 shows furthermore the already-described metal part 36 for retaining the worm shafts 21 and 22, a screw for securing the block 36 on the machine part 28, one of the wing screws 41 and 43 for securing the rail 40 or 44, one of the screws 45 carrying the carrier 46 with the rod 47, the rods 31, 32, 33 and 34 for retaining the guide elements 30, the bearing spindle 48 for the dent lamellae 19, and also the positioning apertures 50, 51 and 52.
  • This figure also shows the shed 17, a shuttle 18 traveling therein, the cloth beat-up 60 and the cloth 23.
  • the additional guide elements 54 are provided. They are, as can be seen in the figure, disposed on the side of the shed 17 positioned opposite the bearing spindle 48 and extend directly up to the position adopted by the outer warp threads when the shed is open. Guide elements 54 are connected by means of a connecting member 63 with the guide elements 30 present on the inner side of the shed 17, Le. in each case one inner element 30 and one outer element 54 are manufactured from a single piece of material, preferably from a single fiat piece of material. Due to the shape provided by the parts 30, 63 and 54, the result is achieved that the dent lamellae 19 are guided also on the outer side of the shed 17.
  • the edge 49 is advantageously so designed that it takes up its position in the immediate vicinity of the rear warp threads of the open shed 17. In this way, a supplementary guide for the shuttles 18 is achieved, by means of which any possibility of the shuttle 18 moving out of the shed is a rearward direction is avoided. Analogously, it is of course advisable to dispose the edges 55 of theguide elements 54 as near as possible to the position obtained with the shed 17 open of the forward warp threads, in order that travel-out of the shuttle 18 in the forward direction (i.e. to the left as viewed in FIGURE 4) may be avoided.
  • Advantageous materials for the guide elements 30 are hard-rolled aluminum sheet, plastic coated metal sheet or plastic plates reinforced with fabric or glass fibres.
  • the elements 30 are advantageously punched-out in a single working step.
  • only the guide elements 54 are provided.
  • the elements 54 there are formed in the elements 54 apertures (shown in broken lines at their ends) through which rods 61 and 62 are pushed in the manner already described for the rods 31 to 34.
  • the elements 54 are retained with prior-described mutual spacing from each other by spacing elements in order that the free mobility of the lamellae 19 between the elements 54 may be assured.
  • the assembly thus formed can be joined to the loom frame in readily releasable manner.
  • neither the connecting member 63 nor the elements 30 are provided. With this arrangement, the dent lamellae 19 are held with mutual spacing by means of spacing discs attached on the bearing spindle 48.
  • a further embodiment of the invention comprises a form of design whereby the greater part of the guide elements is shaped in the manner of the elements 30 shown in FIGURE 2.
  • Individual guide elements which are arranged with predetermined regular spacing, have however additionally the connecting member 63 shown in FIGURE 4 and the second element 54 carried thereby.
  • there are provided over the length of 'a shuttle at least three and on the average approximately five such guide elements of the latter type. These elements, which have the shape corresponding to the parts 30, 63 and 54, are inserted with the predetermined spacing between the guide elements having the shape of part 30 only.
  • the guide elements delimiting the shed on both sides the result is achieved that travel-out of the shuttle in a forward direction out of the shed is avoided without thereby hindering the view of the shuttles traveling through the shed.
  • the guide elements 30 may exhibit a degree of looseness.
  • the points about the spiral spacing member 35, 42 or the entire lower surface of the assembly of guide elements 30 are embedded in a hardenable composition.
  • An advantageous method of carrying this into effect consists in dipping the assembly to a certain degree, for example approximately 2 mm., in a hardenable material, using a tank. As this is done, probably due to capillary effect, there accumulates about the spirals 35 and 42 somewhat more of the hardenable material than Epoxide resin has been found to be suitable as the hardenable composition.
  • An arrangement on a weaving loom for the actuation of reed dent lamellae that extend through a shed formed by warp threads on the loom comprising a bearing spindle extending perpendicular to the warp threads, a plurality of reed dent lamellae arranged along the length of the bearing spindle and individually pivotable about said spindle, each of said reed dent lamellae having a narrow elongated body with an opening at one end through which said spindle extends and being of a suflicient length that its other end extends permanently through the shed of warp threads, means for pivoting said reed dent lamellae about said spindle in such a manner that the lamellae act to drive a plurality of shuttles through the shed and to beat up the weft thread inserted by said shuttles, the forces imparting the pivotal movement to said reed dent lamellae and the forces driving the shuttles through the shed acting on each of said
  • each dent lamella is arranged between two guide elements.
