Patent number: 9182043Abstract: A valve device for use in a feeding apparatus releases raw material into raw material processing machinery for the manufacture of high-voltage cable. The valve device includes a valve body including a first valve member having a conical shape and including at least one opening extending between a tip of the first valve member and a corresponding base portion of the first valve member, and a second valve member including at least one cover element. One of the valve members is rotatable with respect to the other valve member between a first operating position in which the at least one cover element uncovers the at least one opening, thereby allowing the raw material to flow through the valve device, and a second operating position in which the at least one cover element covers the at least one opening, thereby preventing raw material from flowing through the valve device.Type: GrantFiled: December 1, 2010Date of Patent: November 10, 2015Assignee: PRYSMIAN S.P.A.Inventor: Walter Castiglioni

Patent number: 8535033Abstract: A method for manufacturing a cable, the cable including at least one transmissive element and at least one coating layer made of a polymeric material and arranged at a radially outer position with respect to the transmissive element. The method includes the steps of: a) feeding the polymeric material to an extrusion apparatus including an extrusion head, the extrusion head including a male die; a female die coaxially arranged with respect to the male die; a conveying channel, at least one portion of which is defined between the male die and the female die; and b) controlling a cross-sectional area of the at least one portion of the conveying channel in response to a detected quantity, the quantity being caused to vary during the manufacturing of the cable as a function of the actual extrusion speed. An extrusion apparatus for carrying out the process.Type: GrantFiled: February 23, 2012Date of Patent: September 17, 2013Assignee: Prysmian Cavi e Sistemi Energia S.R.L.Inventors: Walter Castiglioni, Luca Balconi, Alberto Bareggi, Sergio Belli
