Definitions

  • the present invention relates to an improvement made to the control members of the reciprocating device of the wire distributor guides during a winding operation.
  • the wire guide is pivotally mounted on the support body by means of an assembly essentially consisting of two arms arranged at right angles, the wire guide being disposed at the end of the one of the arms and the end of the other arm being equipped with a roller sliding along a groove made in a bar, called "sine bar"; it is known, moreover, that by modifying the inclination of this sine bar, the stroke of the thread guide can be varied, this combined with a clock or in connection with the magnification of the spool, which makes it possible to do biconical windings.
  • the wire guides describe at the end two parallel spokes while the pivoting of the sine bar is done on an arc of circle whose center is located substantially in the middle of said bar, which results in dela-offset from the path traveled by the pebble provo-; as for a deformation of the coil.
  • the improvement according to the invention is characterized by the fact that the ends of the guide groove of the sinus bar in which the roller controlling the angular displacement of the wire guide bears, are bent in opposite directions, so as to communicate a acceleration at the thread guide at the end of the stroke, while the support of said thread guide has a delayed movement at this time due to the passage of the cam tip, this acceleration making it possible to distribute the thread at constant or accelerated speed.
  • the course of the wire guide will of course depend on the windings formed.
  • the cam tip radii are between 10 and 100 millimeters and can be executed using a "Lemniscate de Bernouilly" to facilitate deceleration and acceleration of the wire guides.
  • the correction on the sine bar is complementary to the shapes of these points and can be further accentuated so as to accelerate the speeds of the wire guides at the end of their travel.
  • the pivot axis of the sine shield will also receive, during the formation of the coil, a compound movement making it possible to move it slightly so that the roller causing the angular displacement of the thread guide always bears on the same profile of the curve provided at the ends of the groove of the sine bar and this whatever the diameter of the winding formed.
  • the sine bar coil connection mechanism is not shown in the patent.
  • the movement of the sine bar is produced through a stroke calculated so that the mean position of the latter corresponds with the beats of the thread guides which traverse it.
  • the groove 8 of the sine bar 6 has at each of its ends curved parts 10, 23 in opposite directions, which allow to communicate to the wire guide, an acceleration at the end of the race, while the support 9 of said thread guide has a delayed movement at this time due to the tip radius of the cam. Because of this acceleration, a movement of the wire guide is obtained which is identical to that which would have been given by a cam with pointed ends and a conventional sinus bar comprising a rectilinear groove. In this way, it is possible to produce windings having the same characteristics as before. and this at beating speeds two to three times higher than the current system.
  • the groove of the sinus bar according to the invention has a rectilinear part having a length of 14.8 centimeters, the curved parts having a radius of 2 centimeters, the total length of the sinus bar 6 being 16 centimeters.
  • the pivot axis 7 of the sinus bar can be moved between two positions 11, 12. This movement is obtained by providing in the sine bar. a light 24 in which the axis 7 is guided. This movement is obtained in synchronism with the angular movement of said sinus bar by the action of a guide finger 13 which is supported in a groove 14 of the bar.
  • the device making the connection between the coil and the sine bar is not shown in the patent. Thanks to such an installation, it was possible to wind textile threads, filaments, at speeds two or three times higher, the biconical windings formed being perfectly regular.
