  • the standard dimensions of a poster are either 2 m 2 (posters said to be small) with a width of 2500 mm, or 8 or 9 m 2 (so-called large posters) with a respective width of 3200 mm or 3600 mm.
  • width or “width” of a poster means the horizontal dimension of the poster relating to a vertical notion of positioning the poster when one looks at its graphic impression / its visual. . Its edges
  • lateral is meant the dimension corresponding to the height of the poster in the position of display of the poster, that is to say the direction perpendicular to the width.
  • edges parallel to the width and perpendicular to the lateral edges are said transverse edges.

  • Partial preparation machines are available which, after unrolling the reel, produce printed visuals, trimming the lateral edges of the posters and cutting the posters (visuals) parallel to the width of the sheet. However, these machines do not allow to deposit zip. The zip is manually deposited on each separate poster, as well as reinforcing adhesives.

Indeed, as and when printing, the sheet is rolled parallel to its width; when the sheet is then unwound by the machine of the invention, the attachment of the zip will be well according to the width since it will be perpendicular to the unwinding direction.
  • the prior art machines that automatically fix the zip perform the operation in the unwinding direction, that is, perpendicularly to the width of the print, imposing print widths on the printers. which are today at the maximum of order especially 3.2 m so that the visual once the poster in place in a rolling panel is in the right direction from top to bottom.

  • this machine has the advantage of combining all the preparation operations, including those optional, in a minimum time. Therefore, surprisingly, despite a semi-continuous scrolling of a continuous sheet of visuals / posters to be prepared by temporarily stopping the machine to perform the successive operations of transverse cutting and zip apposition, this This machine does not generate a yield loss, but rather enables all the operations, including the optional ones, to be performed in a completely optimized time.

  • the individual posters are rolled parallel to their width, that is to say parallel to the longitudinal axis of the zip.
  • the machine 1 preferably comprises the connecting table 33 which is arranged immediately after the upstream support roll 3 'and before the regulation puppet 6.
  • This connection table 33 is suction to hold in place the end of the unrolled sheet of the first reel and the beginning of the unrolled sheet of the second reel.
  • the second spool is loaded on the support means 3 of the machine having previously removed the first empty spool, and is unrolled above the support roller 3 'and the suction connection table 33.
  • connection table 33 is provided a connection device 34 able to move parallel to the axis Y and possibly comprising means for cutting each edge of the end of the first coil and the beginning of the second coil to ensure perfect parallelism of the edges, and gluing means for bonding the two respective end edges of the first and second spools.
  • the connection is thus automated.
  • the data acquired by the detection means 7 are also processed to possibly correct in response a drift of the width and act on the mobility of the support 3B of the coil.
  • the automated machine of the invention allows itself to perform all the operations of preparing a printed sheet of printed visuals to turn it into individual posters ready for use and able to be wound for their packaging and their transport parallel to the assembly zip they have.
