Definitions

  • the invention relates to a tufting machine with at least one of a series of tufting needles load-bearing needle bar and a needle module that has a number of tufting needles and on the Barre a tufting machine can be determined.
  • the tufting needles are in each case continuous Straight lines arranged in a row (see DE-C-19 528 152).
  • the base fabric is each related to the stitch spacing the row of tufting needles. It is also known to have two such rows of Set tufting needles at the same time on a needle bar so that when the needle bar moves two rows of punctures arise (see US-A-3 641 956).
  • transverse ribs in the Form the finished product if with a relatively large stitch spacing, e.g. > 3.5 mm, worked becomes. These cross ribs represent an undesirable, annoying pattern on the carpet.
  • the object of the present invention is to eliminate this disruptive pattern with simple to eliminate equipment.
  • the invention provides a tufting machine at the outset mentioned type so that in each row - or at least when using several rows in every second row - the tufting needles at different distances parallel to the bar axis are offset, the offset of the tufting needles within a row at most half of the Stitch distance in the tuft direction corresponds.
  • the offset can meet the respective requirements be adjusted.
  • the offset of the tufting needles within a row is at least one tenth of the Stitch distance in the tuft direction corresponds.
  • a tufting machine which is distinguished by the fact that that the offset (S) of the tufting needles in a row is determined from the quotient 50: (Stitch number / dm). This results in a completely even distribution of the puncture knobs and thus a safe exclusion of unwanted cross ribs.
  • the tufting machine according to the invention can be designed so that the tufting needles one Row are arranged to the same extent and alternately offset.
  • a number of Needle bar carrying tufting needles consisting of two parallel to each other, each parallel ingot sections carrying mutually extending tufting needles are formed, at least of which one is variably adjustable in its distance from the other to the offset of the tufting needles to choose within the series.
  • the offset of the needles in a row for each tufting can be set specifically.
  • the invention provides for the solution of the task, a needle module, which is thereby is distinguished by the fact that the tufting needles are offset at different distances across the row, whereby the offset of the tufting needles within the row is a maximum of half the stitch spacing in Tuft direction corresponds.
  • rows of needles can then be generated be as they are formed by directly setting the needles on the bar can.
  • Figure 1 shows a module with a module body 1, which is a series of in a straight line aligned tufting needles 2 carries. These modules are on one, not shown Needle bar fixed and in this way form a row of needles lying on a straight line.
  • the puncture pattern shown in FIG. 1 with the stitch spacing S1 follows from this.
  • the tufting process With a low pole and a relatively large stitch spacing, this results in a surface image with annoying cross ribs between the straight rows of puncture points.
  • Figure 2 shows a module for the construction of a tufting machine according to the invention.
  • a module body 3 again attached several tufting needles 4, but in the longitudinal direction of the Module and thus in the longitudinal direction of the needle bar, not shown, transversely to the bar and thus are also offset transversely to the module body by the dimension S2.
  • a tufting process leads in each case to a puncture pattern as shown between lines 5. It comes down to this In this way, an even distribution of the puncture sites and at the same time a reduction the distance between the puncture points in the tuft direction according to arrow 6.
  • the offset the tufting needles 4 of a row can be adapted to the particular circumstances.
  • One in particular A good effect is achieved if the offset of the tufting needles (4) determines in a row is from the quotient 50: (number of stitches / dm).
  • the arrangement according to the invention is particularly suitable for the production of low-pole goods, in other words with a pole height ⁇ 3.5 mm.
  • modules as well as with direct attachment provide two or more rows of needles on the bar. It can have the desired effect can be brought about by the fact that the tufting needles of every second row in the described Are arranged offset.
  • a tufting machine is shown in part, in which the needle bar in one rear, fixed bar section 7 and a front, variably adjustable bar section 8 is divided. By adjusting the position of the bar section 8, the offset can the tufting needles can be varied within the row as desired.
  • the tufting needles defined in the bar sections 7, 8 are 9 each bent so that their shafts 10 the other bar section are closer than the associated pistons 11. It can then be a simple Form the row of needles without any needle offset.
