Abstract

The method relates to a control cycle for operating a multiple-layer (I, II, III) laminating press and is used for the non-porous lamination of workpieces positioned in a vacuum. Instead of simultaneously evacuating and subsequently laminating the workpieces, the layers of the press are successively activated. For laminating workpieces 10, 20, 30, which are supported in vacuum frames 12, 22, etc., plunger 1 is initially moved upwards only until heating plate 14 on layer I contacts workpiece 10 and the associated vacuum frame 12 with sealing rings 13. Then, by evacuating duct 26 in heating plate 24, positioned above the sealed chamber 15, the latter is evacuated to a predetermined value.

Method for Operating a Multiple-Layer Laminating Press

The method relates to a control cycle for operating a multiple-layer (I, II, III) laminating press and is used for the non-porous lamination of workpieces positioned in a vacuum. Instead of simultaneously evacuating and subsequently laminating the workpieces, the layers of the press are successively activated. For laminating workpieces 10, 20, 30, which are supported in vacuum frames 12, 22, etc., plunger 1 is initially moved upwards only until heating plate 14 on layer I contacts workpiece 10 and the associated vacuum frame 12 with sealing rings
13. Then, by evacuating duct 26 in heating plate 24, positioned above the sealed chamber 15, the latter is evacuated to a predetermined value. Subsequently, plunger 1 is moved upwards to the next layer, and the same process is repeated by means of heating plate 24 for workpiece 20 in conjunction with vacuum frame 22 and evacuating duct 36 in heating plate 34 until finally workpiece 30, etc., has been handled (Fig. 1). It is only after all layers have been closed and evacuated that heating plates 14, 24, 34, etc., are heated, and plunger 1 is moved upwards at full laminating pressure (Fig. 2).
