<p>The equipment consists of a mould (1, 17, 14), formed by a central body (14) and a first head (2) and a second head (17) connected to opposite sides of the central body (14), and also has a rigid and perforated guide (5), axially centred inside the mould (1, 17, 14) to which the preform tube (10) is longitudinally fitted. This guide is equipped with apertures (9) for passage therethrough of an expander fluid (18) which causes the preform tube (10) to expand against the inner walls of the mould (1, 17, 14) without causing heat exchange between the preform tube (10) and the mould (1, 17, 14).</p> |
