Definitions

  • the subject of the present invention is a process for automatically placing paper in the paper cutter of a printing machine of the type comprising, upstream of the paper cutter, a paper feed roller, a printing roller and a head. printing cooperating with the printing roller and carried by a pivoting cover closing an opening formed in the upper wall of the machine and giving access to the food roller and the printing roller when the cover is raised.
  • the present invention therefore aims to remedy the drawbacks of the method defined above.
  • the present invention relates to a process for automatically placing paper in the paper cutter of a printing machine, of the type comprising, upstream of the paper cutter, a paper feed roll, a print roll and a printhead cooperating with the printing roller and carried by a pivoting cover closing an opening in the upper wall of the machine and giving access to the food roller and the printing roller when the cover is raised, process in which, after opening the cover swivel and place the paper food roll in its housing, unroll the paper from the roll, close the cover, thus retaining the paper at the outlet of the printing roller, we start the machine in the direction of rewinding the paper to bring the end of the tape to the downstream outlet of the printing roller, then restart the machine in the direction of paper unwinding to push the tape up u that its cut free end enters the paper cutter, characterized in that, before closing the cover, the paper is rolled out from the roll until part of it comes out through the upper wall opening and , after closing the cover, the paper being retained between the free end edge of the cover and
  • the process of the invention ensures automatic positioning of the paper in the paper cutter, manual intervention being limited, apart from placing the paper food roll in its housing, when cutting a portion of strip on the free end edge of the cover. Because of this strip end cut, we are assured of the perfect condition of this end, obviously facilitating its introduction into the paper cutter.
  • a printing machine such as for example a fax machine, namely the paper food roll 1, the printing roll 2, cooperating with a print head 3 carried by a pivoting cover 4 around the axis 5, the paper cutter 6 comprising a lower pivoting blade 7 and an upper pivoting blade 8 provided with flexible blades 9.
  • the cover 4 closes an opening made in the upper wall 10 of the machine, and its free end edge 11 faces the corresponding edge 12 of this opening, thus delimiting a gap E allowing the passage of the paper.
  • the guiding element is constituted by a chute 13 which faces at the print head 3 and, on the other side of the roller 2, the guide element is formed by a plate 14 and a stud 15 carried by the cover 4.
  • the paper roll 1 With the cover 4 raised, the paper roll 1 is introduced through the upper opening and put in its housing. Pull on the strip C, which passes over the chute 13 and the printing roller 2, to exit it from the upper opening of an arbitrary length, for example 20 cm.
  • the cover 4 is closed and the print head 3 applies the paper strip in its guide chute 13 and against the printing roller 2.
  • the stud 15 retains at A, against the plate 14, the strip which is retained also between the edge 11 of the cover 4 and the edge 12 of the upper opening.
  • the strip is then pulled by its end in the direction of arrow F to produce its cut at B against the edge 11 of the cover 4.
  • the distance 1 between the points A and B is determined by construction.
  • the machine is then rotated in the direction of rewinding the paper on its roll, so as to swallow up the strip section of length 1 .
