Definitions

  • the paper is palpated by a series of needles, the vertical position of each of which varies depending on whether its lower end abuts against the paper or enters a hole in it.
  • Each needle is associated with a stopper whose position varies as a function of that of the corresponding needle.
  • the advance of the latter causes the translation of the stopper and that of the corresponding needle in order to press the associated hook to this needle.
  • the needle descends more so that the stopper escapes the action of the train of bars.
  • the improvements which are the subject of the present invention aim to remedy this drawback and to eliminate the vertical displacement of the pushing elements of the train of bars while minimizing the time of presence of the paper under the needles.
  • each of them has means of being associated with a movable plate which constitutes a kind of memory of the selection made.
  • the plate in question is moved to cooperate with a needle retaining member so that the selection can then be retained even by uncoupling the latter and the paper.
  • provision is made to vertically move the entire support and paper advance system so that it can advance during the movement of the train of bars.
  • FIG. 1 There is shown in fig. 1 the principle of Verdol mechanics comprising in the known manner a series of needles 1 whose lower end palpates a paper 2 having perforations 2a and which is supported by a drive mechanism 3.
  • Each needle is provided with 'an eyelet 1 a through which passes a horizontal stop 4 movable axially by means of one of the pushing elements 5a of a train of bars 5 so as to communicate this movement to a needle 6 against the reaction of a compression spring 7.
  • the needle 6 being associated with a hook 8, if the train of bars 5 moves to the right the hook 8 is deformed for example so that its upper beak 8a escapes from a claw 9a of a frame 9.
  • the bottom of the hook is associated with a heddle 10 intended for lifting a warp yarn, which is placed on a loom.
  • the set of needles 1 is applied against the paper 2 which moves in a jerky manner, synchronized with the movement of the needles, that is to say their vertical movement.
  • the corresponding stopper 4 is located opposite the element 5a of the train of bars 5 so that if the latter is moved the stopper undergoes translation to the right.
  • the paper is perforated in a strictly reverse manner at two successive positions. According to the invention there is provided a device capable of permitting the inversion of the selection without advancing the paper.
  • a plate 12 having as many perforations 12a as needles above the paper so that the latter pass through all of said perforations.
  • Each needle is provided with two U-shaped bends 1 b, 1 of depth less than the width of the perforation 12a and the height of their transverse veil oriented vertically is greater than the thickness of the plate 12.
  • a device for reading the perforated paper comprising simple means for inverting the selection and which may advantageously include a system for storing the latter so as to save time on the advance of the paper.
