Abstract
The method and device for machining a sheet and controlling the thickness between the opposite faces of said sheet in a press between sheet engaging surfaces, at least one of which is a bearing surface of narrow width extending across the width of the sheet, in which the space between them is controlled to modify the thickness of the sheet in a series of successive steps which include moving the sheet relative to the sheet engaging surfaces, stopping the movement of the sheet and moving the sheet engaging surfaces against the sheet to compress the sheet to a predetermined thickness and controlling the stepped movement of the sheet and the movement of the sheet engaging surfaces in alternate and successive sequences.
