Abstract (en)
[origin: EP0123106A2] The method is also suitable for sheets which are coated with lacquer for the purpose of deep drawing. In order to be able to remove an individual sheet from a stack of sheet steel, the temperature of one region lying between two points at which the sheet to be removed is tightly held is changed greatly, so that the sheet to be removed warps and can be removed, e.g., by means of a vacuum sucker. A device for carrying out this method possesses, on both sides of a holding-down device which is pressed against a central region of the sheet to be removed, in each case a gas burner and vacuum suckers which are applied in the corners of the sheet to be removed. <IMAGE>
