METHODS AND APPARATUSES FOR COMPRESSION MOULDING MULTILAYERED OBJECTS, CORRESPONDING DOSES AND MULTILAYERED OBJECT

摘要

A method comprises stages of: dispensing a multilayer dose (68, 78, 88) comprising a principal material (64) delimited by an external lateral surface (74) and a secondary material (65) which is at least partially contained within the principal material (64), the secondary material (65) having a tubular conformation; compression-moulding the multilayer dose (68, 78, 88) in order to obtain an object (73) having a multilayer wall (55); a distance (D) between the second material (65) and the external lateral surface (74) in the multilayer dose (68, 78, 88) being less than or equal to a thickness of the multilayer wall (55).
