Process and device for making composite panels with natural stone slab

Abstract

Abstract A description is given of a process for producing composite stone slabs which each comprise a carrier layer of concrete and a natural-stone slab (4), the two of which are intimately connected to each other. The proposed mechanical process consists in that the natural-stone slab (4), which has been turned such that its upper side faces downwards, is moved onto a vibrating table and enclosed in a sealing manner by a mould frame (1), in that concrete is then introduced into the mould frame (1) and compacted by vibration, and in that the concrete layer applied in this manner is moulded by raising the mould frame (1). On its inner side, the mould frame (1) has a region (11) which corresponds approximately to the height of the natural-stone slab (4) and is set back. In this region there is arranged a peripheral groove (13) into which there is introduced a flexible hose (7), the internal pressure of which can be controlled. A description is also given of the moulding machine used and the feed and centring of natural-stone slabs (4). <IMAGE>
