Definitions

  • switchers are arranged to perforate the paper along zones comprising fifty-six rows of eight holes, which zones are separated by an unperforated space.
  • the improvements which are the subject of the present invention aim to achieve an armor mechanism provided with a feeler device for paper capable of successively reading the perforations of the two halves of the same carton.
  • a Verdol paper assigned to the general reference 1 and each of whose edges comprises a series of longitudinal perforations 2 intended to receive radial prongs carried by a rotary drum ensuring the driving of said paper.
  • This is intended to be perforated in successive zones Z of determined width which are separated by a non-perforated transverse space referenced e.
  • the holes are arranged in rows 3 each comprising two rows 3a, 3b of eight holes in the direction of travel of the paper, while in the transverse direction there are twenty-eight rows which gives a total of four hundred and forty-eight possibilities of perforations.
  • a single row 3 comprising two rows 3a, 3b of eight holes offset longitudinally. The spacing of the holes is such that the distance between the geometric axes of the first hole in row 3a to the last in row 3b corresponds at the aforementioned distance Z.
  • each hole of a zone Z is assigned to a reading element or needle which abuts on the paper if there is no hole or on the contrary crosses it in order to actuate a needle which found in connection with a hook.
  • each zone is palpated at once, the information collected corresponding to the selection of the hooks for the passage of a pick.
  • This area is also called “cardboard”.
  • the zone Z is divided into two strips of the same width, each comprising a succession of two rows 3 of four holes.
  • Each of these bands has been referenced Z 1 and Z 2 in the figure considered.
  • the control device comprises, as illustrated in FIG. 2 to 7 a maltese cross 4 wedged on the shaft of the paper drive drum and a simple trainer 5 rotating continuously.
  • the maltese cross 4 has two perpendicular grooves 4a, 4b constituting four notches distributed regularly over its periphery, while the driver 5 is provided with two studs 5a, 5b whose distances from its center are different.
  • the distance d separating the stud 5a from the center of the trainer is greater than that D 1 which separates the stud 5b from said center.
  • the trainer 5 is wedged on a shaft (not shown) suitably driven in order to communicate to the malta cross the desired angular displacements.
  • the stud 5a is located at the entrance to the groove 4b which is oriented so as to determine with the horizontal an angle greater than 45 ° by a value.
  • the trainer 5 causes by turning the rotation of the maltese cross 4, the stud 5a performing as usual a round trip in the corresponding part of the groove 4b. It emerges from this when the maltese cross 4 has rotated in the opposite direction to that of the coach 5, that is to say clockwise, by an angle greater than 45 ° from the quantity ⁇ Under these conditions the total rotation of the maltese cross 4 is 90 ° + 2 ⁇ .
  • the outlet of the groove 4a of the maltese cross is then oriented relative to the horizontal at an angle of 45 ° - ⁇ (fig. 5). It is at this orientation that the stud 5b enters said groove 4a to cause the rotation of the maltese cross 4. Again the stud 5b makes a round trip in the groove considered to exit from the latter (fig. 7) when oriented at an angle of 45 ° - ⁇ below the horizontal. In these conditions the maltese cross 4 described an angle of 90 ° - 2 ⁇ .
  • the groove 4d is then oriented obliquely at an angle of 45 ° + ⁇ above the horizontal so that the stud 5a will come to penetrate this groove as illustrated in FIG. 2.
  • the stopping time of the maltese cross corresponds to the time necessary to read the perforations in each zone.
  • a particularly well-adapted execution comprises a maltese cross with four notches driving through a set of pinions having a reduction ratio of 9/1 the shaft carrying the paper drive drum. Eighteen advances are thus obtained for a revolution of the shaft which carries the paper advance drum. With this arrangement, the average immobilization times for probing and moving the paper are, expressed in degrees of rotation of the loom, about 200 ° and 160 °.
