Abstract
A die 6 for continuous extrusion of a tubular semi- finished product 12 is associated with measuring elements 13 for measuring the speed of surface movement of the semi-finished product 12, at corresponding reading points ("P") distributed over the perimeter and lying in a common plane orthogonal to the direction of advance of the semi-finished product 12 and located outside and behind the extrusion die 6. One or more electronic controllers 29 connected to the measuring elements 13 compares the measured values of speed to indicate a situation of non-uniformity of thickness of the semi- finished product 12 when at least one of these values is found to be excessively different from the other measured values. Following the indication, regulating elements 13 associated with the extrusion die 6 are brought into action to correct the non-uniformity of thickness. <IMAGE>
