Definitions

  • the eye is offset to one side of the line joining the centers of the carrying rods and is also displaced laterally in regard to the center line of the adjoining heddle shaft portion, and if two sets of heddles are provided with eyes offset on opposite sides, a Duplex arrangement of heddles can be assembled.
  • This invention relates to heddles for use in weaving looms and more particularly to heddles which are made by punching from steel strip.
  • One of the problems with this type of heddle is that of warp threads catching on the edges of heddles other than that through which they are threaded. This is particularly the case with very fine warp threads and as a result, it becomes necessary to polish all the punched-out edges of the heddles which will be in the zone of the warp shed when in use. It is an object of the invention to reduce the amount of polishing which is necessary.
  • Another object of the invention is to reduce the weight of the heddles for any particular application.
  • a heddle made from strip material is bounded along one of its longitudinal sides by a straight edge at least in the zone which works in the warp shed and the heddle eye is so disposed in relation to the adjoining portions of the heddle shaft itself that it is displaced laterally from the centre line passing through the middle of the adjacent portions of the heddle shaft.
  • a heddle in accordance with the invention can be made quite narrow through the major portion of its length, and it is preferred that the heddle eye shall be offset laterally relatively to the longitudinal centre line of this narrow part away from the straight edge. It may then be necessary to widen the heddle in the immediate vicinity of the eye, the widening being accomplished at the opposite side of the heddle to the straight edge.
  • FIG. 1 is a side view of a heddle
  • FIG. 2 is a front view of a series of heddles similar to that shown in FIG. 1,
  • FIG. 3 is a view similar to FIG. 1, but showing a complementary heddle in which the'heddle eye is displaced on the opposite side to that shown in FIG. 1,
  • FIG. 4 is a side view of two heddles, one in accordance with each of FIGS. 1 and 3 assembled on a heddle frame, and 1 FIG. 5 is a view similar to FIG. 4 but showing an alternative construction.
  • a heddle 1 made of strip metal is formed at its ends in the conventional manner with upper and lower loops 2 and 3 open on one side.
  • the end loops are J-shaped, but it will be understood that the end loops could be C-shaped, claw shaped or shaped in any other convenient manner.
  • Top and bottom heddle carrying rods 4 extend through the upper and lower end loops 2 and 3.
  • a heddle eye 5 is formed in the heddle, and usually this is positioned midway between the top and bottom heddle carrying rods 4. In this construction, the heddle eye 5 is displaced laterally with respect to the longitudinal axis XX passing through the centre of the thicknesses of the heddle carrying rods 4.
  • the heddle eye is also positioned as close as possible to the right hand edge 6 of the heddle.
  • material is removed from the left hand side of the heddle to produce the shaped edge 7. This metal is removed so as to reduce the weight of the heddle assembly. Because of the lateral displacement of the heddle eye 5, material can be removed from the steel strip not only in the upper heddle section 8 and the lower heddle section 9, but also in the region of the eye itself.
  • FIG. 3 there is shown another example in which a heddle 12 is provided with end loops 13 and 14 and mounted on heddle carrying rods 4.
  • a heddle eye 15 is formed in the middle of the length of the heddle and is displaced as far as possible from the longitudinal axis XX laterally towards the left hand edge 17.
  • material has been removed from the right hand side, leaving a shaped narrow edge 16 at that side.
  • narrow upper and lower sections 18 and 19 above and below the eye.
  • FIG. 4 illustrates a further advantage of heddles in accordance with the invention.
  • This arrangement produces a double row, or so called Duplex arrangement of the heddle eyes without the two sets of heddles occupying more width than the steel strip of which they were made. It is because there are no projections towards the outside in the region of the heddle eyes that it becomes possible to maintain the overall width of the heddle assembly equal to that of the steel strip material from which the heddles are produced. Moreover, it is possible to use these heddles for narrow harness divisions of, for example, and 12 millimetres. Nor is it necessary to bend the steel strip edgewise and this is an advantage because the steel strip is usually hardened and consequently the bending process is not easy and frequently results in the formation of cracks.
  • FIG. 5 shows a further arrangement in accordance with the invention.
  • the heddles themselves have to be of greater width than in previously described constructions, and thereby the space between two heddles would become too small with a double row set of eyes.
  • a heddle 22 has end loops 23 and 24 engaging on the heddle carrying rods 4.
  • a heddle eye 25 wider than that used in the previous examples is provided in the middle of the length of the heddle 22. This heddle eye is also displaced laterally with respect to the longitudinal axis X-X and in relation to the adjacent heddle sections 28 and 29. In the zone of the warp shed (i.e.
  • the narrow edge 27 remains straight and the reduction in width from the overall width of the steel strip takes place in the upper and lower sections 28 and 29 on the right hand side thus producing a shaped edge 26.
  • the two shoulders 30 and 31 on the edge 26 become rather more pronounced.
  • the heddle carrying rods 4 are carried by heddle carrying rod holders 32 connected to the top and bottom staves (not shown) of the heddle fra-mes. Spacers 33 are provided between the rods 4 and the holders 32 to accommodate hooks 34 and 35 formed in the end loops of the heddle. It is clear from FIG. 5 that the smallest possible harness division is determined by the distance of the narrow edge 26 of the heddle 22 from the opposite side of the heddle carrying rod holder 32. This dimension determines the greatest width of steel strip from which the heddle 22 can be made without the harness division being influenced or widened.
  • a single layer heddle made from a strip of material provided at its ends with loops open at one side for mounting the heddle on the carrying rods in a heddle frame, one longitudinal edge of said heddle forming a straight continuous line from one end to the other end of the same, a heddle eye being provided between the ends of said strip, said heddle eye being laterally displaced with respect to the longitudinal axis passing through the center of the thickness of the heddle carrying rods, said strip being cut away above and below said heddle eye along the other longitudinal edge a distance extending from adjacent said eye to a point short before said open loops at the ends of said strip, said cut away portions forming edges which are disposed parallel to said straight continuous line of the first mentioned longitudinal edge.
  • a heddle according to claim 1 in which said straight continuous edge and the two other edges formed by said cut away portions above and below said heddle eye are all disposed to one side of said longitudinal axis passing through the center of the thickness of said heddle carrying rods.
  • a heddle according to claim 1 in which the cut away portions above and below said heddle eye leave enlargernents in said strip adjacent said two open loops, said enlargements being directed away from the straight continuous edge of said strip and having an inclined edge merging into the open loop at the ends of said strip, said enlargements also extending beyond said longitudinal axis passing through the center of the thickness of said heddle carrying rods.
  • a heddle according to claim 1 in which that portion of said strip of material which is provided with said heddle eye is narrower in width than the ends of said strip provided with said open loops.
