Definitions

  • the present invention relates to a process and a machine for manufacturing shaped profiles in curved plywood for covering columns and alike.
  • the traditional process of manufacturing of shaped profiles in curved plywood for covering columns and alike provides for the overlay of several flat wooden sheets with interposed adhesive, that are made adhere to each other by means of a heated press of substantially semicircular section, which compresses said sheets one against the other determining the bending with a curvature radius correspondent to that of the press itself.
  • object of the present invention has been to provide a process and a machine specifically fit for manufacturing shaped profiles of considerable length in curved plywood.
  • a process for manufacturing shaped profiles in curved plywood comprising overlay of several flat wooden sheets with interposed adhesive and application of pressure over said overlaid sheets by means of a shaped press at high temperature for the mutual adhesion of the sheets themselves and their bending with a desired curvature radius, characterized in that said pressure is obtained by inflating an inflatable flexible sack which substains said flat sheets beneath said press.
  • a machine comprising a heated press of curved section correspondent to that desired for the profile to manufacture and means for providing a pressure engagement between said press and a set of wooden flat sheets overlaid together with interposed adhesive to determine the adhesion of the sheets themselves and their bending up to a desired shape, characterized in that said means for providing a pressure engagement comprise an inflatable flexible sack which substain said flat sheets beneath said press.
  • Fig. 1 is shown schematically in perspective view a set of wooden flat sheets 1, between a layer of adhesive 2 working at high temperature is interposed.
  • the set of fig. 1 is inserted in a machine comprising a shaped press 3, by way of example of semicircular section, heated at high temperature.
  • Beneath press 3 as shown in Fig. 2, an inflatable flexible sack 5, initially deflated, which supports the set of wooden overlaid sheets 1 of Fig. 1, is placed inside an envelope 4.
  • the edge bending can naturally be modified by varying the front shape of press 3.
