摘要： A valve device (120) is proposed for use in feeding apparatus releasing raw material into a raw material processing machinery (105) for the manufacturing of high- voltage cable. In the solution according to embodiments of the present invention, the valve device includes a valve body (205) comprising a first valve member (220) having a conical shape and including at least one opening (230) extending between a tip of the first valve member and a corresponding base portion (210b) of the first valve member, and a second valve member (225) including at least one cover element (245); one of said valve member (220, 225) is rotatable with respect to the other valve member (225, 220) between a first operating position in which the at least one cover element (245) uncovers the at least one opening (230), thereby allowing the raw material to flow through the valve device, and a second operating position in which the at least one cover element (245) covers the at least one opening (230), thereby preventing raw material from flowing through the valve device.

摘要： The present invention relates to a method for manufacturing a cable, said cable comprising at least one transmissive element (3) and at least one coating layer (100) made of a polymeric material and arranged at a radially outer position with respect to the transmissive element (3). The method comprises the steps of: a) feeding the polymeric material to an extrusion apparatus including an extrusion head (1), the extrusion head (1) comprising: a male die (12); a female die (13), coaxially arranged with respect to said male die (12); a conveying channel (20), at least one portion of which being defined between said male die (12) and said female die (13); and b) controlling a cross-sectional area of said at least one portion of the conveying channel (20) in response to a detected quantity, said quantity being caused to vary during the manufacturing of the cable as a function of the actual extrusion speed. The present invention further relates to an extrusion apparatus for carrying out said process.
