Definitions

  • ABSTRACT A Jacquard heald is secured to a fastening hook or e1- ement by an elatic retraction cord gripped at its ends by helical spirals on the heald and hook.
  • the inner diameter of the spirals is slightly smaller than the crosssectional diameter of the cord, whereby the latter is securely held in the spirals.
  • Jacquard healds with elastic retractors are known in the prior art in various different configurations. In the modern Jacquard weaving method they replace more and more the conventional pull-down by means of lingoes, since in high speed looms the lingoes cannot drop fast enough.
  • Elastic retractors have been made of helical downpull springs, fine rubber tubes, natural rubber threads, and synthetic rubber threads which are covered with cotton or rayon. Different opinions exist about the suitability of these various alternatives. Threads made of Lycra are also desirable since with this material an appropriate spring characteristic and high rupture strength can be achieved. The employment of such Lycra threads created problems, however, because the connections between the Jacquard heald and the elastic thread on one end and between the elastic and the fastening element on the other end could not be solved properly.
  • This invention avoids the disadvantages of the known connections between the elastic threads and the metal parts of the Jacquard healds and the fastening elements respectively, and on the other hand creates a connection which can be easily and automatically manufactured and which requires very little space.
  • the invention is characterised in that the connecting element between the Jacquard heald and the fastening element respectively and the elastic thread is provided by means of a helical spiral whose end entwines the elastic thread, the inside diameters of the spirals being smaller than the diameter of the elastic thread before the latter has been squeezed into the spiral.
  • connection between the spirals and the ends of the elastic thread can additionally be improved by applying a glue or a lacquer coat at the end of the Jacquard heald and the fastening element in the region of the spiral. This coat could be automatically sprayed on.
  • FIG. 1 shows a Jacquard heald with an elastic retractor and fastening element according to the invention
  • FIG. 2 shows an enlargement of the lower end of the Jacquard heald
  • FIG. 3 shows the fastening element in an enlarged scale
  • FIGS. 4 and 5 show two possibilities of how to fix a wire spiral on the Jacquard heald.
  • FIG. 1 the Jacquard heald 1 is attached to an elastic thread or member 2 secured to a fastening element 3.
  • the ends of the thread 2 are entwined in the helical wire spiral 4 of the Jacquard heald l and in the spiral 5 of the fastening element 3.
  • the loop 1 1 above the spi ral 4 does not belong to the invention and serves only for lining-up the Jacquard healds.
  • FIG. 2 shows an enlarged part-view of the Jacquard heald l with the wire spiral 4 and the elastic thread 2.
  • FIG. 3 shows how the elastic thread 2 is inserted into the wire spiral 5 of the fastening element 3.
  • the illustration of how the elastic thread 2 is tied in by the spirals 4 and 5 is slightly exaggerated. This is achieved due to the fact that the inside diameter of the wire spirals 4 and 5 is kept slightly smaller than the diameter of the elastic thread 2.
  • the elastic thread 2 can by means of a simple operation be inserted into the spiral by curling the rubber thread into the individual windings of the spiral. This operation could of course be also done automatically by means of a suitable machine.
  • the sections in the regions of the spirals 4 and 5 could be sprayed by lacquer or glue.
  • FIGS. 4 and 5 two alternatives are illustrated showing a spiral 8 & 10 made as a separate or component part which can be fitted onto Jacquard heald 1.
  • the end of Jacquard heald 1 gets bent and forms a hook 6 as shown in FIG; 4.
  • An extended spiral 8 is pushed over the slightly open hook 6.
  • the shank 7 of the hook 6 receives therefore a pre-tension which secures the spiral 8 in position.
  • FIG. 5 shows a similar mounting method.
  • a loop 9 is made in the twin wire on the end of the Jacquard heald 1 . While sliding the spiral 10 over this section the loop 9 is entwined and the spiral 10 is fixed in its position.
  • the diameter of the spirals 8 and 10 respectively will be determined on one side by the gauge of the wire of the Jacquard heald 1 and on the other side by the crosssection of the elastic thread 2.
  • the connections of FIGS. 4 and 5 may be soldered after the spirals 8 and 10 have been slid on.
