摘要： A multipolar cable (14) for transmitting energy and/or signals, as well as an extrusion method and apparatus for the production thereof, is described. The multipolar cable (14) according to the invention comprises: at least three transmissive elements (15), and a sheath (16) in which at least three longitudinal housings (17) are defined, the longitudinal housings (17) being intended to house respectively the at least three transmissive elements (15) according to a predetermined configuration and being formed within respective substantially lobe-shaped longitudinal portions (18) of the sheath (16). 10 The multipolar cable (14) of the invention allows to connect the transmissive elements (15) to one or more consumption points by means of at least one connector (20) provided with at least three perforating elements (21).

摘要： An extrusion method and head (1) for depositing by extrusion a polymeric material intended, in particular, for the production of cables including a core and a coating layer arranged at a radially outer position with respect of the core, are described. The method of the invention comprises the steps of feeding the polymeric material in a feeding duct (10) of the extrusion head (1) and of conveying a part of the polymeric material towards an undercut (17) extending in the extrusion head (1) in proximity of an end of said feeding duct (10). Said a method provides that a sealing force between a head body (2) and a conveyor element (3) of the extrusion head (1) is exerted by means of the pushing action exerted by the polymeric material in said undercut (17) in a direction substantially perpendicular to the longitudinal axis of the head body (2).
摘要翻译：描述了一种用于通过挤出沉积聚合物材料的挤出方法和头部（1），特别是用于生产包括相对于芯部的径向外部位置处的芯和涂层的电缆。本发明的方法包括以下步骤：将聚合物材料供给到挤出头（1）的进料管道（10）中，并将聚合物材料的一部分朝着在挤出头（1）中延伸的底切（17）输送，在所述进料管道（10）的端部附近。所述方法规定，头体（2）和挤出头（1）的输送元件（3）之间的密封力通过由所述底切（17）中的聚合物材料施加的推动作用大致垂直于头体（2）的纵向轴线的方向。
