Abstract

The invention refers to a method for manufacturing products made of rigid and plasticised PVC, in particular tubes, section bars, cables and hot rolled elements, where the method is articulated in a single passage, completely continuous with two possible outcomes depending on whether it is applied to extrusion or calendering processes.

Claims

AMENDED CLAIMS[received by the International Bureau on 26 June 2004 (26.06.04);New patent claims
1. A method for manufacturing products made of rigid and plasticised PVC in particular tubes, section bars, cables and calendered elements, characterised in that the method comprises a single passage, completely continuous with two possible outcomes depending on whether it is applied to extrusion or calendering processes, and in that raw materials (1 ) are stored separately and are proportioned (2) according to two different processes.
2. The method as claimed in claim 1 , characterised by a continuous volumetric or gravimetric proportioning of a pre-mixture of solids and a pre-mixture of liquids, fed distinctly into a continuous turbo mixer (3 in Fig. 2).
3. The method as claimed in claim 1 , characterised by a continuous, volumetric or gravimetric proportioning, but separate proportioning of solids and liquids (Fig. 3).
4. The method as claimed in any of the preceding claims, characterised in that inside a turbo mixer (3) runs a constant and homogeneous flow of raw materials which, in their path towards a discharge point, are accurately mixed.
5. The' method as claimed in claim 4, characterised in that depending on the final product, the output of the turbo mixer (3) directly feeds a continuous extruder (4) for the production of tubes, section bars or cables, or a calender (5) for the production of films, sheets or plates.
6. Product manufactured according to the method as claimed in any of the preceding claims.
