Definitions

  • the invention relates to weaving looms, and in particular to broadcloth looms in which the warp yarns are made to shed by healds that are controlled from a jacquard or other patterning mechanism through a harness of cords which pull against lingoes or elastic connectors.
  • Broadcloth looms may be arranged to produce different widths of fabric at will.
  • a loom which might be controlled by two jacquards, may be set up to produce two 72 inch (183 cm) wide fabrics or three 48 inch (l22 cm) wide fabrics.
  • the harness cords fan out from.the jacquard or other patterning mechanism and are guided through eyelets in a comber board before being attached to the healds.
  • the comber board is made up of slips which are short sections of board with rows of eyelets.
  • the slips are usually 6 inch (15.25 cm) long so that twelve of them would be used to produce a 72 inch (183 cm) width fabric.
  • a standard 21 ⁇ 2 inch (6.35 cm) wide spacer is provided for separating the widths of fabric, and this usually has eyelets for the selvedge cords.
  • the invention provides a method for adjusting a broadcloth loom from a first fabric width configuration to a second such configuration, in which harness cords are displaced along the comber board so that the length of each harness cord between its point of attachment to the patterning mechanism and the comber board is unaltered.
  • each harness cord may be fixed between its pointof attachment to the patterning mechanism and a locating ' point between the comber board and the said point of attachment, in which case harness cords are displaced along the comber board so that the length of each harness cord between its locating point and the comber board is unaltered.
  • the harness cords may be guided each in a path which comprises an inclined portion from its locating point to the comber board and the adjustment may then comprise displacing at least some harness cords along the comber board so that they have their inclined portions equally but oppositely inclined.
  • Tne comber board may, as usual, comprise a plurality of slips separable into fabric width sections by spacers.
  • the displacement of the harness cords may thenbe effected by weft-wise displacement of the slips. It is desirable that the slips be made more accurately to length, however, than is customary - hitherto inaccuracies were of no consequence when the loom had to be relevelled anyway.
  • the spacer or spacers in the comber board customarily have aperture to guide harness cords for the selvedge threads. According to one aspect of the present invention, however, apertures for the selvedge threads are provided in a separate board or boards mounted separately from the slips in the comber board.
  • selvedge board may be mounted on a bracket that can slide along the rail in which the slips are carried without interfering with the slips themselves and so that the selvedge cords can be moved along the comber board without interfering with the cords for the main body of the fabric.
  • the selvedge cords will, of course, need to be relevelled after displacement, but there are only a few of them, and this is not a time-consuming operation.
  • the locating points may comprise apertures in an upper guide board and the upper guide board may comprise one spacer whose width is half of that of the spacer or spacers in the comber board.
  • the invention also provides a broadcloth loom for weaving fabrics, comprising a patterning mechanism and a comber board, and means for changing the loom from a first fabric width configuration to a second such configuration by displacing harness cords along the comberboard so that the length of each harness cord between its point of attachment to the patterning mechanism and the comber board is unaltered.
  • the aforementioned means may comprise a locating point for each harness cord defining a fixed path for that cord from its point of attachment to the patterning mechanism to its locating point.
  • the comber board may comprise a plurality of slips separable into fabric width sections by spacers.
  • the locating points may comprise apertures in an upper guideboard, which may comprise at least one spacer whose width is half of that of the spacer or spacers in the comber board.
  • Figure 1 is a diagrammatic representation of a prior art loom set to produce two 72 inch (183 cm) width . fabrics or three 48 inch (122 cm) width fabrics.
  • Figure 2 is a diagrammatic representation of a loom according to the invention set to produce the fabrics of Figure 1.
  • Figure 3 is a diagrammatic representation of another loom arrangement
  • Figure 4 is a cross section through part of the loom shown in Figure 2, drawn to a larger scale.
  • Figure 1 shows diagrammatically two jacquard patterning devices
  • a comber board 13 is located between the jacquards 11 and the heald 12. If two 72 inch (I83 cm) width fabrics are to produced, a single 21 ⁇ 2 inch (6.35 cm) wide spacer 14, shown in full lines, is located centrally of the comber board 13 and twelve 6 inch (15.25 cm) slips 15, also shown in full lines, are located on either side of the central spacer 14.
  • slips and spacers will have to be, from either end, eight slips, one spacer, eight centrally disposed slips, ene spacer and eight slips.
  • Figure 2 shows diagrammatically two jacquard patterning devices 21 which control the healds 22 of a broadcloth loom according to the present invention.
  • a comber " board 23 is located between the jacquards 21 and the healds 22. If two 72 inch (183 cm) width fabrics are to be produced a single 21 ⁇ 2 inch (6.35 cm) wide spacer 24, shown in full lines, is located centrally of the comber board 23 and twelve 6 inch (15.25 cm) slips 25 are located on either side of the central spacer 24 as before.
  • an upper guide board 28 is provided in addition to the comber board 23 and the harness cords 26, shown in full lines, pass from their points of attachment 27 to the jacquards 21, through the upper guide board 28 and through the slips 25 to the healds 22. Again only a few such harness cords 26 are shown for reasons of clarity.
  • the upper guide.board 28 has at least one, in this case three, spacers 29 whose width is half of that of the spacer 24 in the comber board 23, i.e. 11 ⁇ 4 inches (3.18 cm).
  • the loom is levelled with the harness cords 16 in the two by 72 inch(l83 cm) fabric width configuration shown.
  • each harness cord 26 between its point of attachment 27 to the jacquard 21 and the comber board 23 is unaltered by the change from the two by 72 inch (183 cm) fabric width configuration to the three by 48 inch (122 cm) fabric width configuration. So the loom having been levelled for one fabric width configuration, will remain level for the other fabric width configuration, thus saving the time consuming and costly re-levelling operation.
  • the upper guide board 28 can be arranged with more or fewer spacers 29 than shown, and they may be positioned so that changes from any one or more desired fabric width configurations to other desired fabric width configurations may be effected without a change in the path length of the harness cords 26 between their points of attachment 27 to the jacquards 21 and the comber board 23.
  • Figure 3 shows, for simplicity, only the upper guide boar 28 and the comberboard 23 of a different arrangement useful in loomswhere the left hand harness cord must be set in the extreme left hand end position.
  • the upper guide board 28 has, from the left, a row of eight 6 inch (15.25 cm) slips, then a 11 ⁇ 4 (3.18 cm) spacer thenanother eight 6 inch (15.25 cm) slips, then a 21 ⁇ 2 (6.35 cm) spacer, then a further eight 6 inch (15.25 cm) slips.
  • the comber board 23 is shown in three different configurations in Figures 3A, 3B and 3C.
  • Figure 3A shows the comber board 23 setup to produce three forty eight inch (122 cm) widths.
  • Figure 3B shews the rearrangement for two 72 inch (I83 cm) widths.
  • Figure 3C shows a further rearrangement to produce a single 48 inch (122 cm) fabric and a 96 inch (244 cm) fabric.
  • FIG. 4 illustrates a more convenient arrangement for use with the present invention, in which the selvedge cords 30 are guided in eyelet boards 31 mounted by a m ⁇ vable bracket 32 on the rail 33 of the comber board 23.
  • the bracket 32 is simply undamped and moved along the rail 33 to its new position above the healds for the selvedge threads and re-clamped to the rail.
  • the selvedge harness cords will have to be relevelled, but as there are only a few of them in any event this is not a troublesome matter
