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).
