  • An adhesive tape is thus adhered to the surface of the support, more particularly at the cut portions, and is removed, causing with it the portions of film to be removed.
  • the support is a license plate.
  • the cutting means comprise stamping means designed to highlight the cut film portions.
  • the device comprises a zone of withdrawal of the strip relative to the support, the strip forming in this zone an angle of between 5 ° and 20 °, preferably of the order of 10 °, with the plane defined by the support.
  • This angle allows optimal separation of the film portions and the adhesive strip.
  • the drive means of the support comprise at least two drive rollers, arranged opposite one another in the direction of movement of the support.
  • the drive means delimit between them a space of dimension less than or equal to the thickness of the support.
  • the drive is then simply performed by friction of the support on the drive rollers.
  • the pressing means comprise at least one pressure roller, exerting a force on the adhesive strip towards the support.
  • the pressure roller thus makes it possible to improve the adhesion of the adhesive tape to the support.
  • the pressing means are located downstream of the drive means of the support, in the driving direction thereof.
  • the pressing means comprise at least one pair of pressure rollers arranged facing each other in the drive direction of the support.
  • the withdrawal means comprise at least one pair of traction rollers of the adhesive strip, arranged facing each other in the driving direction of the strip.
  • the pull rollers thus pull the adhesive strip so as to remove it from the carrier also causing the corresponding film portions.
  • the withdrawal means of the adhesive strip are located downstream of the pressing means, in the drive direction of the strip.
  • the device comprises a roll forming an adhesive strip reservoir from which the strip is unrolled during its drive, cooperating with a winding roll of the strip, located downstream of the withdrawal means of that in the drive direction of the tape.
  • the new web is then stored on the reservoir roll and the used web is then wound onto the winding roll.
  • the linear drive speed of the adhesive strip is between 1 m / min and 1.5 m / min, preferably of the order of 1.2 m / min.
  • This particular speed makes it possible to obtain a correct removal of the film, while ensuring a production time that is sufficiently low.
  • At least one of the traction rollers is made of silicone.
  • This type of material prevents sticking of the adhesive side of the strip on the roll.
  • the application of the adhesive tape on the support is carried out during the training of the support.
  • the band is removed by forming an angle of between 5 ° and 20 °, preferably of the order of 10 ° relative to the plane defined by the support.
  • Figure 1 is a cross-sectional view of a portion of the device for cutting the film portions
  • Figure 2 is a perspective view from above
  • Figure 3 is a front view
  • Figures 4, 5, 6 and 7 are perspective views of the device in respectively four successive positions of the support during its production;
  • the device applies to the technical field of license plates.
  • This peeling operation increases the production time of a plate and can not be integrated into an industrial plate making process. This operation is also not rewarding for the operator who performs it.
  • Figures 1 to 3 show a film removal device according to the invention for removing portions of film on a support, more particularly portions of film cut at the printed characters of a license plate.
  • the withdrawal device comprises cutting means.
  • the cutting means comprise stamping means comprising a male part 17 and a female part 18.
  • the female part 18 has a recess 19 which has substantially the shape of the character 15 that an operator wants to write on the plate.
  • the cutting means comprise cutting zones 20 disposed in the vicinity of the female portion 18. The cutting zones 20 are located over the entire periphery of the desired character.
  • the male part 17 comprises a projecting member 22 of complementary shape to the recess 19 of the female part 18. It should be noted that a space substantially corresponding to the thickness of the support and in particular of the plate 5, is reserved between the male part 17 and the female part 18.
  • the recess 19 and the projecting member 22 are arranged so as to be vis-à-vis.
  • this device further comprises a body 1 formed of at least two parts 2, 3 articulated with respect to each other, the body 1 comprising an inlet zone 4, intended for inserting a plate 5 with portions of film to be removed, and an exit zone 6, for removing the plate 5 in its final state, that is to say ready for use.
  • the film may be formed by one or more plastic sheets, aluminum foil or glue paper sheets.
  • the device is equipped with a roll 7 forming an adhesive strip reservoir 8 from which the strip is unrolled during its drive, cooperating with a winding roll 9 of the strip 8.
  • the roll 7 forming a reservoir is braked, so to achieve a constant tension of the band during its course.
  • the reservoir roller 7 can store for example 50 m of adhesive tape.
  • the device furthermore comprises plate drive means comprising two drive rollers 10, arranged facing each other. one of the other in the direction of displacement A of the plate 5 and delimiting between them a space of dimension less than or equal to the thickness of the plate 5.
  • the rollers 10 are rotated, one rotating in the opposite direction of the other, at about the same speed. Once the plate 5 engaged by the operator between the drive rollers 10, it is moved in translation in the direction A. The speed of the rollers 10 is adapted to obtain a scroll of the plate 5 of the order of 1.2 m / min.
  • the device further comprises pressing means 11 for applying the adhesive strip 8 to the plate 5, located downstream of the drive means 10 in the driving direction A of the plate 5.
  • pressing means 11 for applying the adhesive strip 8 to the plate 5, located downstream of the drive means 10 in the driving direction A of the plate 5.
  • These comprise two pairs of pressure rollers 12, offset in the drive direction A of the plate and respectively arranged opposite one another in the same direction.
  • Each pair of rolls 12 delimits a space of dimension less than or equal to the thickness of the plate 5, the thickness of the strip 8 then being considered negligible compared to the thickness of the plate 5.
  • the adhesive strip 8 is engaged so as to abut against the roller located on the side of the plate 5 comprising the portions of film to be removed.
  • the device comprises means for removing the adhesive strip.
  • These comprise a pair of traction rollers 13, 14 of the adhesive strip 8, arranged facing each other in the driving direction of the strip 8 and delimiting between them a space of dimension less than or equal to to the thickness of the adhesive tape 8.

  • the roll 13 in contact with the adhesive side of the strip 8 is made of silicone, which makes it possible to avoid gluing the strip 8 onto the corresponding roller 13.
  • the strip 8 forms with the plane defined by the plate, an angle ⁇ of between 5 ° and 20 °, preferably of the order of 10 °, in the zone of withdrawal of the strip, that is to say between the pair of pressure rollers 12 located downstream and the pair of traction rollers 13, 14. This angle can be adjusted by means for adjusting the position of the rollers, not shown here.
  • the adhesive strip 8 is arranged successively, in the unwinding direction thereof, on the reservoir roller 7 of the new strip, at the level of the pressing means 11, at the level of the withdrawal means 13, 14 and then on the roll of winding 9 of the used band.
  • the operator positions the plate 5 on the cutting means. More specifically, it has the plate 5 on the female part 18 of the stamping means.
  • the plate 5 is positioned so that the film is in contact with the female part 18.
  • the male part 22 will come to exert a pressure on the plate 5 by resting on the female part so as to deform the plate 5.
  • This deformation will consist of a transverse elongation so as to obtain the shape of the desired character.
  • the film portions 16 covering the character 15 are now in relief with respect to the surface of the plate 5.
  • the cutting zones 20, located in the vicinity of the periphery of the character 15 will allow the cutting of film portions 16 and more precisely the cutting along the periphery of the character 15.
  • the operator inserts the registration plate 5 between the drive rollers 10. Their rotation in the opposite direction then allows the displacement in translation of the plate 5 until the upstream end of the latter. it is arranged between the pressure rollers 12, as shown in FIG.
  • the gluing step of the adhesive strip 8 begins on the plate 5, in which a pressure roller of each pair comes into bearing against a first face of the plate 5, the other roller bearing against the adhesive strip 8 so as to exert a force in the direction of the plate 5, more precisely in the direction of the face to be glued thereof.
  • the pressure force exerted is of the order of 20 daN, the deformation of the band of 0.5 mm under this load.
  • the used strip, on which the film portions 16 are glued, is then stored on the winding bearing 9, as shown in FIG.
  • the plate In the position shown in Figure 7, the plate is no longer driven by the drive rollers 10 but only by the displacement of the adhesive tape, glued to the plate.
  • the plate 5 is then removed by the operator.
