Definitions

  • the present invention relates to a device for forming chenilles on a crochet textile machine for warp weaving, said textile machine being of the type comprising a plurality of needles set side by side, at least one front bar presenting recesses for guiding said needles, a plurality of thread passers positioned side by side parallel to the front bar forward of the needles and set to engage each a respective warp thread, a plurality of thread-guiding cops positioned above the needles and able to engage each a respective woof thread and means for driving the needles longitudinally to confer thereto an alternating motion along their longitudinal development.
  • the co-operation between needles and thread passers gives rise to a sequence of woven stitches which form a plurality of parallel chains, as many as there are warp threads, which descend progressively from the front bar.
  • the chains are normally concatenated with woof threads borne by respective thread-guiding cops operating above the needles.
  • Each woof thread is selectively laid astride one or more needles and passes underneath them when they reach the return stop.
  • the woof thread placed below the needles is enmeshed in the woven stitches of the warp threads in the following operative cycle.
  • the chenilles that are obtained from the cutting action of the scissors elements i.e. the sections of cut woof threads
  • the technical task constituting the basis for the present invention is to conceive a device for the formation of chenilles for crochet textile machines for warp weaving able substantially to obviate the aforementioned drawbacks.
  • an important aim of the invention is to conceive a device that allows to attain a high precision in the execution of the cut of the woof threads and thereby to obtain regular and uniform chenilles.
  • Another important aim of the invention is to conceive a simple device of reliable operation.
  • a further aim is to obtain a device that allows to set up rapidly with simple operations a crochet textile machine when the production of chenille fabrics is required.
  • a device for the formation of chenilles on a crochet textile machine for warp weaving which is characterised in that it comprises a plurality of cutting elements able to cut woof threads and positioned immediately below the area occupied by the needles wherein the woven stitches are formed and means for controlling said cutting elements.
  • the device according to the invention is globally indicated with the number 1.
  • needles 2 operate, consecutively set side by side parallel to the front bar 4, thread-guiding cops 7 able to carry woof threads 8 to be concatenated with chains 9 formed by woven stitches 9a obtained from the warp threads 6 and all together defining a manufactured item 10.
  • Longitudinal drive means 11 impose on needles 2 a simultaneous alternating motion along the direction of their longitudinal development.
  • the device 1 for the formation of chenilles comprises a plurality of cutting elements 12 able to cut the woof threads 8 of the manufactured item 10 immediately below the area occupied by the needles 2, i.e. the area wherein the stitches 9a are formed.
  • cutting elements 12 advantageously operate on the manufactured item 10 in an area essentially comprised between a common base plane of the needles 10 and a lower edge 4a of the front bar 4.
  • the cutting elements 12 are defined by a plurality of blades slidingly housed in guiding grooves 13 obtained in the front bar 4 and intercalated between the guiding recesses 3 of the needles 2.
  • the blades 12 present a longitudinal development parallel to that of the needles and, similarly thereto, comprise L-shaped rear attachment ends 12a able to be rigidly engaged to control means which, in a preferential embodiment, coincide with the means 11 for longitudinally driving the needles.
  • Such means 11 for longitudinally driving the needles 2 and the blades 12 comprise a movable front bar 14, actuated by appropriate kinematic mechanisms in a way known in itself, which confers simultaneously the same alternating motion to the needles and to the blades themselves.
  • the recesses 13 guiding the blades 12 present a depth suited to set the cutting edges 12c of the blades 12 at an appropriate distance from the needles 2, essentially corresponding to two woven stitches (see figure 4) and in any case preferably not exceeding five woven stitches.
  • the blades 12 At each advancing motion of the needles towards the thread passers 5, the blades 12 also move from a back position wherein they do not emerge from the front bar 4 (see Figure 1) to positions progressively emerging more and more therefrom (see Figure 2).
  • the invention attains important advantages.
  • the device is simpler and more reliable overall than the devices with scissors cutting elements, as it requires no additional driving means.
