Definitions

  • An apparatus for opening multiple sheet paper articles, such as folded newspapers, stitched or bound booklets, prospectus, catalogues and like articles, and for insertion of supplemental sheets into the opened article comprises a series of gripper units attached at equally spaced intervals to a pair of endless travelling conveyor chains, said gripper units comprising two pairs of grippers each having a movable jaw coacting with a fixed jaw which is common to both pairs of grippers, one of said movable jaws being movable in a direction at right angles to the gripping surface of the fixed jaw and in a direction transverse to this gripping surface, whereby said movable jaw upon moving transversely of the gripping surface of the fixed jaw clamps a marginal portion of the multiple sheet paper article to be opened, and upon moving parallel to the gripping surface of the fixed jaw displaces a portion of the clamped sheets of the multiple sheet paper article at a location at which previously the friction between two adjacent sheets had been reduced, said other movable

  • the static friction between opposed surfaces of two adjacent flat articles at the location at which it is desired to separate the stack is reduced, and a force having a component in the plane of the fiat articles is applied to the articles located at one side of side location, whereby the stack is separated at this location.

  • a second gripper In order to retain one of the portions of the article which upon opening will be separated in two portions, a second gripper is provided.
  • This gripper is provided with a wedge-shaped jaw, so that upon release of the portion of the article gripped by the first jaw, the separated portion of the article cannot close again but will slide on the back of this jaw of the second gripper and remain in open separated position.

Accordingly it is possible by a suitable shaping of the cam bars, to move the jaw 76 towards or away from the counter jaw 78 and during this closing or opening movement or during maintenance of the jaw 76 in one of its end positions, to move this jaw additionally along the counter jaw 78 parallel to the surface of this jaw.

It shall be mentioned only that the separating devices 209, 210, 211, 212 each separate the lowermost sheet of an inclined pile of sheets and pull it off the pile in upwardly inclined direction. The separated sheets, as shown in FIG. 17, pass over a deflection member to adapt them to the travelling direction of the outer strands of the conveyers 207 and 208.
  • the articles or copies fed to the conveyer bands are first moved downwardly, and pass around the lower turn of the conveyers, whereafter the opening, clamping and insertion operations are effected as described before, in the adjacent upwardly moving strands of the conveyers 207 and 208.
  • the finished product BZ in which the supplemental sheets have been inserted arrives at the upper turn of the conveyer 207 where it is discharged tangentially into the delivery station 213 formed as a conveyer which discharges the articles laterally out of the apparatus.
  • Apparatus for inserting supplemental sheets into a multiple sheet paper article, such as a newspaper, at a location determined by reduction of the friction between two adjacent sheets of the article prior to or during formation of the article comprising carrier means defining an endless path, a pair of grippers coupled to said carrier means, each gripper having opened and closed positions, the first of said grippers including two jaws and means for moving one jaw relative to the other jaw in a direction towards the end thereof, when said first gripper is closed, article feed means positioned adjacent said path for feeding an article into said first gripper when the same passes the feed means, control means for opening the grippers before said grippers reach said feed means and successively for closing said first gripper to grip a free overlying edge of the article, for moving the said one jaw of the first gripper relative to the said other jaw thereof to separate the article into two portions, for closing the second gripper to grip only one of the said portions and for re-opening the first gripper after the pair of grippers has passed the said feed means, guide means positioned adjacent said path
  • the second gripper includes a fixed and a movable jaw, the movable jaw having a wedge-like back surface opposite its gripping surface, onto which back surface moves the separated portion of the article after having been released from the first gripper.
  • Apparatus as claimed in claim 1 comprising a twoarm level and in which the movable jaw of the first gripper is arranged at one end of said two-armed lever, the pivotal axis of the lever being movable at least approximately in a direction parallel to the gripping surface of the jaw.
  • Apparatus as claimed in claim 4 comprising a pivoting lever and in which the pivotal axis of the two-armed lever is arranged at the free end of said pivoting lever which has its axis stationary with respect to the first gripper.
  • the carrier means comprises an endless two-strand conveyor band, a pair of endless link chains guiding the band along its lateral edges, and a plurality of pairs of grippers, the length of the conveyor band being divided into similar sections by said pairs of grippers.
