Definitions

  • It also relates to a manufacturing process sheets of single-sided corrugated cardboard using in particular a machine of the above type.
  • the chain includes feeding means 3 and 4 respectively in flat sheet, cover, and in flat sheet intended to form the sheet grooved.
  • a preheater 6 for the cover sheet generally consisting of a steam-heated steel cylinder with small rollers called “bar feeders” which are used to vary the paper / cylinder contact area
  • a preconditioner 7 for the fluted sheet which in turn comprises, and in addition, a sheet humidification ramp which promotes the formation of grooves.
  • the chain 2 also includes means 8 of the single-sided cardboard obtained, consisting of by a system of belts in the upper part of the chain.
  • Figure 2 shows more specifically, in view cutting, the machine 1 single face of the chain of figure 1.
  • the machine 1 also includes a first cylinder 12, grooved, upper, stainless steel. he is hollow and arranged to be heated with steam from way known in itself.
  • the second cylinder is for example of the type known as "Air Drive”, manufactured by French company MARTIN.
  • the chamber includes 17 channels drilled on the entire length of the cylinder and communicates with the peripheral surface fluted by holes.
  • Machine 1 includes a third cylinder 18 lower, smooth surface, axis parallel to both first and for example of the same diameter.
  • This cylinder is steam heated in a similar fashion to both first and is arranged to compress the sheet of cover against the edges of the grooves of the corrugated sheet, in contact with the periphery of the cylinder central grooved, as we will see.
  • the machine 1 also includes means 19 for gluing the ridges of the grooves, known in themselves, comprising a laminating roller 20, a glue tank 21 and a glue roller 22.
  • the operating principle of the machine 1 is the next.
  • the sheet 23 is intended to form the sheet grooved.
  • the glue is for example based on starch.
  • the cover sheet 24 is inserted in the lower part and opposite the machine 1.
  • the adhesive joint is therefore obtained by the action combined with the high pressure and the temperature in a split second.
  • the training of the leaves is done by traction, the fluted sheet being driven by the meshing fluted cylinders 12 and 13, and the cover sheet being driven by clamping between the central cylinder 13 and the smooth cylinder 18.
  • EP-A-0 492 310 describes a machine corresponding to the preamble of claim 1, and using fragile, belted systems and exerting strong pressure.
  • the present invention aims to provide a machine and method for manufacturing corrugated cardboard single sided responding better than those previously known to the requirements of the practice, in particular in that that it practically eliminates cuts paper at resonant and / or high speeds speed i.e. for example greater than 300 m / min, and in that it makes it possible to obtain an excellent bonding, which produces a performance corrugated board improved at a low cost and easily enforce.
  • the present invention starts from a an entirely new idea, including significantly reduce the pressure, or even at the completely remove, between the grooved cylinder 12 and the cylinder 18 smooth on the contact surface between the leaves, contrary to what art taught previous, replacing the high pressure with a heater extended leaves against each other.
  • Control means and adjusting the speed of rotation of said fourth cylinder with respect to the speed of rotation of said second cylinder are provided.
  • the first determined value is between of the order of 30 ° and of the order of 80 °
  • the second determined value is between around 90 ° and around 200 °.
  • the invention also provides a method of manufacturing using a machine as described above, and more particularly a manufacturing process a sheet of single-sided corrugated cardboard, from a sheet of corrugated cardboard and a flat sheet of cardboard, called cover, by gluing one on the other according to claim 7.
  • the first determined value is between of the order of 30 ° and of the order of 80 °
  • the second determined value is between around 90 ° and around 200 °.
  • the machine according to the embodiment of the invention more particularly described here comprises on the one hand, a single-sided machine of the type described in reference to Figure 2, and secondly a fourth cylinder arranged as will be described below in reference to figure 4. To simplify, the same reference numbers are used when they designate the same items.
  • the machine according to the invention comprises a fourth cylinder 26 smooth, heating, axis 27, parallel to the axes previous cylinders and located above them, for example directly after the second cylinder on the path of the corrugated sheet.
  • This cylinder is steam heated so similar for example to reach a temperature cylinder skin between 160 ° C and 200 ° C.
  • Means (not shown) for adjusting the the speed of rotation of the cylinder 26, known in themselves, are provided.
  • the cylinder speed ratio 26 and the cardboard scroll is therefore adjustable to ensure the tension of the cover sheet which is rolled up and in contact with the smooth surface of the cylinder.
  • bonding is different from classic collage. Instead of making the joint glue instantly by combined action of heat and strong pressure, bonding is ensured essentially by heat, the pressure being reduced by importantly.
  • cylinder 26 has at least with respect to the plane tangent to the point of contact 29 with cylinder 13 part of its surface on the side of said cylinder 13.
  • the axis 27 of the cylinder 26 can also be located on the side of cylinder 13, relative to the vertical plane passing through the axis 31 of the smooth cylinder 18.
  • a small roller 32 smooth and full, known in itself, and suitable for being in contact with the sheet of corrugated cardboard, the corrugated side is for example provided.
  • the axis 35 of the cylinder 32 is located below the axis 27 of the cylinder 26.
  • Figure 5 shows a schematic view in section along V-V of cylinder 26.
  • It includes two cylindrical ends 37 and 38 mounted on bearings 39, and a cylindrical body 40, for example stainless steel or cast iron, fitted with a central recess 41 supplied with steam at 42 by the end 37.
  • a cylindrical body 40 for example stainless steel or cast iron
  • a motor with variable speed 44 allows you to vary the speed of rotation of the cylinder 26 in a manner known per se, depending on the desired tension for the cardboard corrugated.
  • a device according to the invention retains the qualities of resistance to humidity COBB of the cover paper, without alterations, contrary to what is observed with the devices of the prior art.
