Method for manufacturing perforated extruded constructional elements of terracotta and product

摘要

In order to avoid joining material falling into the extruded constructional elements (4a) exhibiting vertical perforations (2), the orifices of the perforations (2) are at least partially closed on one of the faces of the element (4a). Closure is obtained by supplying an extrusion of clay (6a, 6b) or by the creation of burrs or by a screen or lattice made of synthetic material. IMAGE
