Definitions

  • the invention is intended to improve the lamella comb described at the outset in such a way that it can be adapted to changing warp densities and thus to changing tube widths without the need to replace the lamellae provided with compartment-holding members.
  • each compartment holding element is formed by two protruding projections, now makes it possible for the first time to produce a lamella comb in which the pipe width is not determined by the height of the compartment holding elements.
  • the invention is intended to provide a production method for such a lamella comb in which the sum error mentioned no longer occurs, that is to say the lamella comb can be reproduced exactly.
  • any type of spacer elements arranged between the lamellae can be dispensed with, as a result of which the above-mentioned sum error is excluded a priori.
  • the organ is in the form of a rod and the guide means are formed by grooves, then at the most there can be an error caused by the machine tool used to produce the grooves. In any case, this would be negligibly small and, in addition, the same size for all rod-like organs machined on the same machine tool, so that the organs and thus the lamellar combs are exactly the same in this worst case.
  • the figures show a lamella comb for the weaving rotor of a row shed weaving machine, which consists of a carrier 1, a stop comb 2 and a guide comb 3, both combs being shifted by half a pitch.
  • the structure and mode of operation of a series shed weaving machine with a weaving rotor are assumed to be known and are not explained in more detail here; in this connection reference is made to US Pat. No. 4,290,458. In this patent, the mutual displacement of the two combs 2 and 3 by half a division is described in detail.
  • the stop comb 2 consists of stop slats 4 for striking the weft threads and the guide comb 3 consists of guide slats 5 for the warp threads.
  • the guide lamellae 5 are provided with shed retaining elements which fix the, high or low position of the warp threads and hold the warp threads in their high or low position over their entire wrap angle on the weaving rotor.
  • Fig. 2 in which the individual fins are drawn exaggerated thick, the tube between two adjacent guide fins 5 is designated B and that between two adjacent stop fins 4 is designated C and one can see the mutual displacement of the two fin combs 2 and 3 (Fig. 1) with the slats 4 or 5 by one half pipe width.
  • Fig. 1 there are two warp threads K in each tube of each of the two lamella combs, in the tube B between two guide lamellae 5 both warp threads K are located together either in the up or down position, in the tube C between two stop lamellae 4 there is a warp thread K in each case in the high and the other in the low position.
  • This representation corresponds to a double-stitch plain weave.
  • the compartment-holding members for the warp threads K are formed by projections projecting laterally from the guide lamellae 5.
  • Each guide plate 5 is provided with a first projection 6 or 6 'serving as a compartment holding element for the high position and with a second projection 7 or 7' serving as a compartment holding element for the low position.
  • the first projection 6, 6 ' is formed by a bent part on one edge of the guide slats 5, the second projection 7, 7' is formed in that a kind of window is punched out of the guide slats 5 on three edges and bent around its fourth edge is. Since the compartment-holding members for the up and down compartments are always arranged in different tubes, the first and second projections 6, 6 'and 7, 7' respectively project away from the guide plates 5 on different sides.
  • Each compartment-holding member is formed by two first or second projections 6, 6 'or 7, 7' arranged on the guide fins 5 delimiting the respective tube.
  • the two projections, each forming a compartment-holding member project against one another (FIGS. 2, 3) and are offset with respect to one another in the warp direction, which corresponds approximately to the direction of arrow II in FIG. 1.
  • the aforementioned lamella comb 3 is thus composed of two types of guide lamella 5: From guide lamellae 5 with a first projection 6 against the weft direction A and with a second projection 7 in the weft direction A and from guide lamellae 5 with a first projection 6 'in the weft direction A and with a second projection 7' against the weft direction A.
  • the formation of the compartment holding members by two mutually protruding and mutually offset projections 6, 6 'or 7, 7' enables the use of a single set of fins for different pipe widths by reducing the pipe width by moving the guide fins 5 from a minimum value, in which the projections 6, 7; 6 ', 7' of one guide lamella 5 each abut the adjacent guide lamella 5 with its free end face, that is to say they overlap to a minimum value, up to a minimum value at which the said end faces are aligned with one another or the projections 6, 7; 6 ', 7' just overlap.
  • the carrier 1 for the lamellar combs 2, 3 (FIG. 1) consists, as shown, of two parallel rails 8 and 9, which extend over the weaving width, one of which is provided with a dovetail 10.
  • the dovetail 10 is provided for insertion into a corresponding groove on the casing of the weaving rotor (not shown).
  • the rail 8 carrying the dovetail 10 is distributed over its length at intervals of approximately 3 to 10 cm with threaded bores 11, into each of which a countersunk screw 12 is screwed, which projects with one end out of the rail 8 and against the rail 9 presses. By turning the screws 12, the distance between the two rails 8 and 9 and thus the cross section of the carrier 1 can be adjusted.
  • the inner edge of one fastening leg 13 or 14, which runs perpendicular to the screws 12, is of the same length as the corresponding dimension of the rail 9 and the inner edge of the other fastening leg 13 or 14, which runs parallel to the screws 12, is longer than the sum of the corresponding dimensions of the two Rails 8 and 9.
  • Each carrier 1 formed by the rails 8, 9 carries two lamella combs 2 and 3 (FIG. 1) displaced relative to one another by a half pitch or tube width B or C with stop lamellae 4 or guide lamellae 5.
  • the fastening legs 13 and 14 of the two lamella types are like this oriented that the fastening legs parallel to the screws 12 of one type of lamella encompass the rails 8, 9 on one side and the same fastening legs of the other type of lamella encompass the rails 8, 9 on the other side wall thereof.
  • the lamella combs are produced in such a way that the individual lamellae 4 and 5 are placed on a pair of rails 8, 9 with a length corresponding to the length of the loom rotor outside the weaving machine.
  • the screws 12 are loosened so far that they can be easily attached.
  • a stop plate 4 and a guide plate 5 are alternately attached, in the latter alternately a guide plate 5 with projections 6, 7 and one with projections 6 ', 7'.
  • the fins 4, 5 Before the fins 4, 5 are fixed, they have to be positioned on the rails 8, 9 with exact observance of their mutual spacing, the pipe width or pitch.
  • This positioning is carried out with the aid of rod-like organs which are arranged parallel to the support 1 and are provided with guide means for the slats, the division of the guide means corresponding to the desired division of the slats.
  • These organs are preferably formed by racks, the teeth of which have the desired division and a triangular or trapezoidal profile.
  • These racks can form part of a teaching and can be clamped together with the carrier 1 in such a way that the racks are positioned with respect to the carrier 1 such that the slats 4 and 5, when they are plugged onto the carrier 1, are straight with their in Fig.
  • the slats 4 and 5 positioned in this way can then. are glued to the rails 8, 9 by a suitable adhesive which is soluble in heat or a liquid. If the division of the lamellar combs is to be changed, the adhesive connection can be released by exposure to heat or the solvent.
  • a pair of racks 23, 26 and 24, 25 is provided, in which the lamellae 4 or 5 are each guided in the region of their two projections 17 and 18.
  • the lamellae 4, 5 On the inner edge of their inner leg running perpendicular to the screws 12, the lamellae 4, 5 each have a gradation 31 or 32, with which they grip around the toothed rack 24 or 23 assigned to the other lamella 5 or 4 from the outside and therefore not in Contact with the toothing projecting outwards from the carrier 1.
  • the racks 23 to 26 only need to be replaced.
  • the fins 5 with the compartment holding members can be adapted to the new pipe width within wide limits because of the overlapping projections 6, 6 'and 7, 7', the fins 4 also only need to be repositioned.
  • the projections 6, 6 '; 7,7 ' not necessarily in the warp direction, but could also be offset with respect to one another in the radial direction with respect to the weaving rotor. In this case, the projections 6, 6 'or 7, 7' would lie one above the other.
