Definitions

  • THIS INVENTION relates to corrugating apparatus in which a continuous single-faced board consisting of a corrugated sheet with glue applied to the exposed tips of the corrugations is to be brought together with a liner sheet which is thus bonded to the glued tips to form a double-faced board, and the composite board is carried through the apparatus whilst heat is applied to cure the glue to form a bond between the liner and the corrugated tips of the single-faced board.
  • a system of this kind incorporates a series of hot plate surfaces over which the continuous composite board is conveyed and means are required to hold the board down firmly against the heated surfaces to ensure substantially constant heat transfer into the board.
  • Such a system occupies a considerable amount of floor space to accommodate a sufficiently long line of heaters for adequate heat transfer to be ensured.
  • corrugating apparatus in which a continuous single-faced board consisting of a corrugated sheet glued on one face to a first flat sheet and with glue applied to the exposed tips on the opposite face of the corrugated board, is to be brought together while continuously advanced through the apparatus, with a second flat sheet to be adhered to said exposed tips, the apparatus comprising transport means to advance the corrugated board and the second flat sheet simultaneously and in the same direction through the apparatus, guide means to bring them together in face-to-face abutment, and a dielectric heating means to cure the glue to form a bond between the board and the sheet.
  • the apparatus causes the combined board and sheet to be transported over a hot plate surface prior to heating by the dielectric heating means.
  • the combined board and sheet are maintained in close relationship with the heated surface by a flexible loading means disposed on the side of the board remote from the heated surface and adapted to bear upon the board and to maintain it in contact with the heated surface.
  • a single-faced corrugated board 10 with glue applied to the tips of the corrugations is brought together, beneath a roller 11 with a continuous liner sheet 12 .
  • the double-faced board so formed then travels in the direction of arrow 13 across a number of steam chests 14 providing a continuous upper hot plate surface 15 .
  • a series of weight rollers 17 bears against the upper surface of belt 16 as it passes over the hot plate surface 15 to maintain contact between the latter and the liner 12 .
  • the weight rollers 17 are replaced by a series of flexible vessels or bags 20 which are at least partially filled with a fluid medium such as water or a gas.
  • a fluid medium such as water or a gas.
  • Each vessel 20 bears upon a thin plate 21 which is loosely pivotable about a transverse rod 22 at its upstream end in relation to the direction of travel of the board.
  • the flexibility of the vessels 20 ensures that the board 10, 11 , is maintained in contact with the hot plate surface 15 irrespective of any undulation or distortion thereof, thus ensuring efficient heat transfer to the board.
  • the plates 21 are replaced by a linked and flexible "matting".
  • a line of the steam chests 14 and vessels 20 is required to ensure adequate heat transfer to the board in order to cure the glue and form a permanent and strong bond.
  • a machine constructed as described may extend in a single line over a distance of some 30 metres or more thus occupying a considerable length of factory floor space.
  • Section A is a short version of the device illustrated in Fig. 2 i.e. a steam chest of approximately 3 metres in length with flexible vessels 32 thereabove adapted to maintain the board 10, 12 in superimposed close relationship over the hot plate surface of chest 31 for initial curing of the glue.
  • the combined board is fed beneath a canopy 33 beneath which is an array 34 of electrodes providing radio frequency dielectric heating. Radio frequency generates heat within the water content of a product, so giving higher concentration of energy in the areas where it is required.
  • a vacuum conveyor 36 forms the transport section C of the apparatus, pulling the board through Sections A and B without the need for a top blanket belt running along the full length of the apparatus.
  • Section B Owing to the effect of the dielectric (RF) heating in Section B, adequate heat transfer is ensured to form a complete bond between the board 10 and liner sheet 12 , resulting in a much shorter conventional preheating Section A. Indeed, in some applications section A may be omitted and Section B providing adequate heat transfer into the combined board.
  • RF dielectric
  • RF heating not only enables a considerable reduction in the length of any conventional preheating system but also imposes a lower temperature on the board thus largely overcoming a tendency of the board to warp or shrink.
  • the process is economical because only water molecules are heated, not the substrate, and heating is uniform through the combined flutings of the board.
