Definitions

  • the present invention relates to a new type of tensioner usable on textile machines in which the wire feed is made by unwinding from fixed spools, such as in particular warpers.
  • the invention will be described for such an application (warper), but it is obvious that this is not limiting and that such a tensioner could be used in all cases where similar problems arise. , for example checking the tension of warp threads on a loom.
  • one of the essential conditions to be observed is that of giving the plurality of threads which make up such a chain, a constant and identical tension for all the threads. Furthermore, it is also desirable to be able to adapt the tension as a function of the threads treated.
  • a new type of tensioner of particularly simple design which not only allows easy adjustment of the tension which it communicates with the wire, but which, in addition, can be grouped in the form of modules comprising a plurality of identical tensioners whose adjustment can be carried out in a single operation.
  • the tensioner according to the invention has the advantage of communicating a constant tension over time, practically foolproof.
  • the simultaneous movement of all the counterweights of the elementary tensioners is obtained by a control element consisting of two rigid rods arranged on either side of said counterweights and movable longitudinally.
  • each counterweight can include a brake enabling it to be locked on its support rod in a determined position.
  • the tensioner according to the invention therefore consists of an assembly mounted on a fixed support box (element not shown) and which is intended to be placed on the path of the wire F to which we wish communicate a constant and predetermined tension.
  • Such an assembly essentially consists of two elements, one fixed, designated by the general reference (1), the other mobile designated by the general reference (2), and which cooperate with each other to communicate the desired tension on the wire F.
  • the fixed element is in the form of a comb comprising teeth (2a, 2b, 2c, 2d) pierced with through orifices (3a, 3b, 3c, 3d) aligned.
  • the mobile element (2) is, for its part, disposed below the axis passing through the alignment of the orifices (3a, 3b, 3c, 3d) and can pivot around an axis (4) located back from the fixed element (1).
  • Such an assembly (2) is in the form of a body (5) provided, at its upper part, with teeth (6a, 6b, 6c) also provided with through orifices (7a, 7b, 7c), said teeth can come to interpenetrate between the teeth of the comb of the fixed element (1).
  • the body (5) is balanced by an assembly forming a pendulum and which comprises a rod (7) over the length of which can slide a counterweight (8).
  • the counterweight (8) preferably comprises a braking system (9) making it possible to immobilize it in a position determined according to the length of the rod (7). Thanks to such an assembly, it is possible to communicate a precise and determined tension to the wire F by passing the latter alternately inside the orifices (2a, 2b, 2c, 2d) - (3a, 3b, 3c, 3d) fixed (1) and mobile (2) combs. In fact, when the counterweight is moved away from the pivot axis (4), the tension exerted by the mobile element (2) on the wire F is reduced.
  • such an assembly can easily be adapted to carry out a simultaneous adjustment of a plurality of tensioning elements by mounting them on a common support box and by moving the counterweights (8) by means of a single element, by example by means of two rods (10), arranged transversely, and movable parallel to the running of the wire. Consequently, such a tensioning assembly is particularly suitable in all cases where a plurality of threads are worked simultaneously, which is the case on the warpers.
