Title:
METHOD FOR PRODUCING A CERAMIC ARTICLE FOR CLADDING BUILDING STRUCTURES AND DEVICE FOR CUTTING A SLAB OF A PLASTIC MIXTURE
Document Type and Number:
WIPO Patent Application WO2000070157
Kind Code:
A3
Abstract:
The present invention relates to a method that involves forming a slab of a plastic mixture and cutting the slab into preforms using two cutting instruments. When cutting the slab, the cutting edges of said instruments move in the separation plane of the slab towards each other and from one end position to a second one. It is thus possible to align the positions of the cutting-instrument cutting edges on the separation surface along a line which is located between the two parallel surfaces of the slab, said surfaces being the front surfaces of the ceramic article. The device for cutting the slab of plastic mixture comprises a substrate (1) for receiving the portion of the slab (2) to be cut as well as a cutting mechanism connected to a driver and comprising a blade (7) and a bow (5) with a tensioned string (6). The blade (7) and the bow (5) are mounted so as to be capable of rotation in the separation plane of the slab (2) from one end position into a second one where the cutting edge (8) of the blade (7) and the string (6) are located between the horizontal surfaces (L and L1) of the slab (2), wherein in this position the string (6) is brought into contact with the blade (7).
