Definitions

  • a metal sheet comprising a panel and two standing flanges wherein one or both flanges have a non-rectilinear form in the plane of the panel is obtained, when starting from a sheet having rectilinear flanges.
  • Sheets having rectilinear flanges are commonly known in the art.
  • the non-rectilinear form is introduced by the forming of one or more corrugations in the panel. Where a corrugation is formed, an extra length of the panel is taken up as seen over the width of the panel, so the panel and thus the sheet will become narrower there.
  • the apparatus comprises means for guiding the flange after the corrugations have been formed by the forming means, and more preferably comprises means for drawing the sheet through the forming means.
  • These guiding means can also consist of horizontal guiding rolls and some roll pairs to guide the flange of the sheet. In the same way, a driven roll can be present to draw the sheet through the forming means.
  • the roll or rolls with a circular protrusion are motor driven and more preferably adjustable in height.
  • the rolls with the protrusion have to press the corrugation in the panel and for that reason are preferably motor driven.
  • By making these rolls adjustable in height is will be possible to form corrugations in the panel having a varying height.
  • the cooperating rolls can have a constant height.
  • the rolls are replaceable.
  • the apparatus can be easily adjusted for a sheet for which a different form of the corrugation is desired.
  • These protrusions can be different, for instance have a different height, to form different corrugations at the same time.
  • FIG 1 schematically shows a top view of an essentially tapered metal sheet according to the invention.
  • the tapered sheet 1 has a panel 10 and two flanges 11, 12. These flanges are curved inward or concave in the plane of the panel due to the forming of the corrugations 13, 14 near both flange 11 and flange 12.
  • the metal sheet had been formed in a conventional manner, so with two straight flanges on both sides of the panel.
  • the corrugations 13, 14 have been formed in the middle portion of the panel 10, causing this middle portion of the panel to contract and thus giving the sheet the concave shape. Though it is not clearly visible in figure 1, all the corrugations have a declining height over their end portions or over both halves of their lengths from the middle of the panel, causing the smooth curves of the concave flanges.
  • the height adjusting mechanism will raise or lower the lower roll(s) 113 to form the corrugation in the metal sheet.
  • the height adjusting device will be controlled by a controlling device (not shown) which can be programmed to form the desired corrugations with the desired length and the desired increasing or decreasing height in the sheet.
  • the second forming unit 120 can form a second corrugation, or can form the corrugation formed by the first forming unit to a greater height.
  • the run out unit 130 supports the front end of the metal sheet while the corrugations are formed in the back end of the sheet, and draws the sheet through the forming units using the driven rolls 134.
  • other designed feed, forming and roll out units can be used, as long as they serve the purpose to form corrugations into metal panels having two flanges at opposite sides of a panel.
