Definitions

  • This invention relates to a method for constructing panels for roll shutter boxed, a plant for implementing the method, and a panel obtained by the method.
  • Boxes for roll shutters of slatted type are well known. They were formerly of wooden construction but are now constructed of bent and seam-jointed sheet metal or extruded aluminium, or are in the form of panels of extruded plastics construction coupled together.
  • An object of the invention is to provide a panel for roll shutter boxes which has the same characteristics as internally lined metal panels but which can be constructed more easily and at lower cost.
  • a further object of the invention is to provide a panel having good dimensional stability and resistance to deformation, compared with plastics panels.
  • a plant for implementing the method is claimed in claim 5.
  • a panel obtained by the method is claimed in claim 8.
  • the method for constructing panels according to the invention involves the use of a plant comprising substantially a reel 2 from which a metal strip 4 having a thickness of 0.25-.0.7 mm and preferably 0.32-0.4 mm is unwound and which is positioned upstream of a forming machine 6, at the exit of which a polyurethane foam injection station 8 is provided.
  • a reel 10 Downstream of said station 8 there are provided a reel 10 from which aluminium or plastic film 14 is unwound, and a shaping unit 14.
  • the film thickness is a few hundredths of a mm in the case of aluminium film, or a few tenths of a mm in the case of plastic film.
  • Said unit 14 consists of two overlying belt conveyors 16, 18, with the lower conveyor 16 having a flat surface to support and advance the shaped strip and the upper conveyor 18 having its outer surface shaped to conform to the shape to be given to the foam in its unhardened state.
  • said shaped surface is obtained by applying shim portions 19.
  • the metal strip 4 is unwound from the reel 2 and is passed through the forming machine in which it is shaped to the desired form.
  • the shaped strip obtained has its edges bent to C-shape and slightly diverging outwards.
  • Polyurethane foam 21 is then injected into the shaped strip, the film 12 from the reel 10 then being laid on the foam, to rest on the edges 25.
  • the shaped strip is then advanced into the shaping unit, which adheres perfectly to the strip, and in which the upper conveyor 18 not only gives the required shape to the foam by means of the shims 19, but also, via the interposed film, closes the longitudinal compartment intended for the expanding foam.
  • the shaped strip is then fed to the polymerization tunnel 20 where the foam hardens, after which the shaped strip is cut to obtain the panel 24 of the desired length.
  • Figure 4 represents a roll shutter box obtained from the panels illustrated in Figures 2 and 3, in which it can be seen that they are connected together by inserting an appendix 26 of the "male” panel into a seat 29 of the "female” panel, with a seal gasket 30 therebetween.
