Definitions

  • the present invention relates to a machine for manufacturing corrugated cardboard coated on one side, commonly called “single-sided corrugator of the type according to which the pre-glued corrugated paper is applied to the cover paper by means of a smooth press. constituted by a cylinder driven in rotation (see FR-A-15 38 872).
  • paper-fluting is formed in any single-sided corrugator by passing a sheet of paper between two fluted cylinders heated by their interior space with saturated steam and applied in meshing, generally with using two cylinders.
  • glue is deposited on the top of the grooves thereof by passing it against a gluing cylinder animated with a continuous rotational movement, then the paper strip is bonded -covering on the corrugated paper by pressing them one on the other between the second grooved cylinder and a smooth cylindrical press, also heated with saturated steam and driven in synchronism with the two grooved cylinders.
  • the single-sided cardboard thus formed is then pulled upwards by passing between lifting belts.
  • the cover paper is not positively entrained in its bonding zone, but is entrained by pinching between the second grooved cylinder and the smooth press. It is therefore necessary to exert a strong pressure between the smooth press and the second grooved cylinder which on the one hand risks breaking the cover paper, which is relatively thin, and on the other hand exerts a traction on the point of glue which may cause poor bonding.
  • the cover paper is positively driven by the smooth press, so that the drawbacks of the previous devices are not found there. It is characterized in that it uses a smooth cylindrical press equipped with means for attracting the strip of cover paper in all or part of the zone of passage of said paper around said press.
  • the corrugated paper 1 is, in a conventional manner, corrugated by passing between two grooved cylinders 3 and 4 placed one above the other as shown in the drawing, then glued to a strip 2 of cover paper between the lower grooved cylinder 4 and a smooth cylinder 5, or “smooth press", to finally exit the machine in the form of a strip of single-sided corrugated cardboard 6.
  • the grooved cylinders 3 and 4 are heated by steam at a temperature of approximately 200 ° C. and under pressure of approximately 16 bars admitted by a conventional device not shown, inside these cylinders which are therefore hollow consequently, which allows the paper strip 1 to reach the optimum temperature for thermoforming the groove.
  • the fluting paper receives glue through a gluing cylinder 7 which partially dips in a glue tank 8.
  • the thickness of glue deposited on the fluting paper is adjusted by the interval existing between the cylinder 7 and an auxiliary cylinder 9, called a laminator or doctor cylinder.
  • the cover paper 2 is not only heated by passage over the smooth press 5, fitted like the cylinders 3 and 4 with a hollow interior space. 9 receiving saturated steam, but is previously preheated by passing along two preheating cylinders (10, 11) heated like all the others with saturated steam in the same way.
  • all of the cylinders (3, 4, 5, 7, 9) are driven in synchronism by the general movement of the machine, with the respective directions of rotation indicated by the arrows in the drawing. , the cylinders 10 and 11 also being free to rotate.
  • the cylinder 5, or smoothing press is provided with means making it possible to press the cover paper 2 by suction onto it over the entire portion of circumference BB ′ on which they are normally in contact. This ensures a positive drive of the strip 2 by the smooth press 5, which in particular makes it possible to reduce the pressure of the cylinder 4 on the cylinder 5 and therefore to conserve the cover paper.
  • the means of suction of the cover paper in the area BB ′ of the cylinder 5 can be very varied and can be both of the type using pneumatic suction forces and of attraction forces of another type, for example electrostatic.
  • the cylinder 5 has, as already mentioned, a hollow interior space 9 in which saturating vapor is circulated so as to preheat the sheet 2.
  • longitudinal channels 16 In the body of the ferrule formed by the cylinder 5 are pierced longitudinal channels 16 regularly distributed. Axial holes 17 of a smaller diameter are also drilled regularly ment along each channel 16 and put each of these in communication with larger cavities 18 machined on the outside of the cylinder 5.
  • each end of the cylinder 5 and on the edge thereof, is installed a fixed, sealed, hollow, arcuate sector 19, which rests on the part BB 'of the edge of the cylinder 5 which corresponds to the area of passage of the cover paper on the cylinder 5.
  • Each sector 19 is connected to a vacuum pump not shown and operating continuously.
  • each channel 16 passes alternately through the sectors 19 and then into the open air.
  • the passage in front of the sectors 19 makes it possible to transmit the depression due to the vacuum pump on the cavities 18 which correspond to the channels 16 located in said sectors.
  • the paper is consequently held by suction against the smooth cylinder 5 throughout the retaining zone encompassed by the sectors 19. The paper is then released from its force of attraction by bringing the channels 16 back into the open air when these escape sectors 19.
  • the sectors 19 encompass the entire area BB '. They could obviously include only a part of it.
