Definitions

  • the "conventional stitchers are arranged to perforate the paper in zones comprising fifty-six rows of eight holes, which zones are separated by an unperforated space. It is easily understood that when a mechanism with eight rows of hooks is used, there is a corresponding number of needles intended for palpating the paper so that the mechanics must include means for making the needles work twice in each zoned. It is therefore necessary to use specially fitted stitchers on which the paper is moved in two different strokes, the first corresponding to the half-height of each zone while the other must be equal to said half-height increased by space between two zones. Since work with an eight-hook mechanism is relatively rare, it seems abnormal to create a special stitching machine. We then thought of using only half of the holes in each zone so that we work cardboard by cardboard on the armor mechanics as usual. But of course such a way of working leads to a significant waste of paper since in fact we use twice as much as necessary.
  • 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 and 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 and the last hole in row 3b corresponds to the width of the aforementioned zone Z.
  • each zone is palpated in a roui iois, 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 Z1 and Z2 in the figure considered.
  • the control device comprises, as illustrated in FIG. 2 to 7 a maltese cross 4 wedged on the drum shaft paper drive and a simple 5 continuously rotating driver.
  • 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 D1 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 cross this malt 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 ° of a value a.
  • the coach 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 malta cross 4a rotated in the opposite direction to that of the coach 5, that is to say clockwise, by an angle greater than 45 ° of the quantity at. Under these conditions the total rotation of the maltese cross 4 is 90 ° + 2a.
  • the outlet of the groove 4a of the maltese cross is then oriented relative to the horizontal at an angle of 45 ° - a (fig. 5). It is at this orientation that the stud 5b penetrates into 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 ° - a below the horizontal. Under these conditions the maltese cross 4 described an angle of 90 ° - 2a.
  • the groove 4d is then oriented obliquely at an angle of 45 ° + a 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 °.
