Definitions

  • the present invention relates to an improvement made to machines making it possible to make gimped threads.
  • the operation of wrapping a thread generally consists, as shown diagrammatically in FIG. 1 appended, of winding in a helix, around a thread (1), forming a core, one or two threads (2a, 2b) called “covering thread” or “wrapping thread", so that the core (1) remains rectilinear, the ) wrapping thread (s) being wound helically around said core.
  • covering thread or “wrapping thread”
  • the core wire passes through the two hollow pins and, during its path, the wrapping wire of each coil mounted on each of the hollow pins, forms a balloon which is wound helically around soul thread.
  • conventional wrapping machines have two hollow spindles equipped with their wrapping of wrapping thread, arranged one above the other, and which can rotate either in the same direction or in the opposite direction. Furthermore, the driving of said spindles can be carried out either by means of a tangential belt system driving all the spindles simultaneously, or by means of individual motors controlling each spindle.
  • a wire presence detector is preferably placed on the path of each core wire before they pass inside the voltage regulators.
  • the path of the core wires inside the covering assembly is carried out in a perfectly straight line, the internal diameter of the channel of the hollow covering pins being such that there is no friction against the internal wall.
  • the voltage regulators (5a, 5b, 5c, 5d ..) will be regulators of the type which do not exert pinching on the wires, for example individually adjustable eddy current tensioners.
  • the elementary core wires (1a, 1b, 1c, 1d ..) leaving the tension regulators are brought to the covering station proper (16) in the form of a sheet (see FIG. 3), the strands of which converge towards each other towards a joining guide (12) arranged at the entrance to the first hollow spindle (8a).
  • an additional deflection element (13) is provided downstream of the voltage regulator (5), and the elementary wires converge towards the joining guide (12) passing under a platform (14) on which can be move the operator.
  • the guide elements (6a, 6b, 13,12) which the machine according to the invention comprises, are preferably constituted by idle rollers having a relatively large diameter (greater than fifteen millimeters) and whose surface condition is such that it does not affect the quality of the elementary wires (1a, 1b ..).
  • the covering assembly proper (16) consists of conventional hollow spindles of the individual drive type (motor spindle).
  • the covering of the wire (1) formed by the assembly of the elementary wires (1a, 1b, 1c, 1d) is carried out in a conventional manner during the passage through the hollow pins.
  • the wrapped yarn formed at the outlet of the wrapping assembly (16) is called up via a conventional positive deliverer (10) and the formed yarn is returned in (11) also in a conventional manner.
  • the path of the core wire (1) inside the covering assembly (16) is perfectly rectilinear and there is no friction against the walls of the internal conduit that each pin has.
  • Such a particularly simple type of machine design makes it possible to obtain a large number of different wires, the constituents of which (core and covering) may be of the same nature or of a different nature. Furthermore, such a machine makes it possible to work both conventional threads and technical threads, such as high tenacity threads, thermostable threads, threads with high mechanical performance, conductive threads. By the design of such a machine, it is possible to produce webs (1) made up of wires having very different characteristics from each others and whose titles, mechanical characteristics, can vary within wide limits.
  • the core (1) of which consists of four different types of thread kept parallel one being a carbon-based thread (title: 300 tex ), the other an aramid wire (title: 600 tex), the third single-strand stainless steel wire (diameter: 0.08 mm) associated with a fourth polypropylene wire (title: 167 dtex), the core (1 ) thus formed being wrapped by means of two threads of different nature, one based on high tenacity polyester (280 dtex) and the second based on polypropylene (title: 167 dtex).
  • the machine according to the invention has been described for an assembly in which the core can comprise four elementary wires and which therefore comprises, for each position, four voltage regulators, it is obvious that the 'It is not outside the scope of the invention to produce machines comprising, for each position, a greater or lesser number of four deliverers.
