发明名称 METHOD OF CONTROLLING THE OPENING AND CLOSING OF A BLOW MOULD AND BLOWING DEVICE FOR IMPLEMENTING SAME.
摘要 <p>The invention relates to a method of controlling the opening and closing of a book-type blow mould that is used to produce containers from a thermoplastic material, such as PET, by blowing or blow-drawing heated preforms. According to the invention, the mould (1) comprises at least two mould halves (2a, 2b) which can be moved away from one another by rotating same around a shared fixed pivot pin (3). The invention is characterised in that the two mould halves (2a, 2b) are opened asymmetrically on either side of the parting plane (5) thereof and, as a result, the mould half that is open the most forms a larger passage for introducing an auxiliary member, such as a clamp arm, into the mould.</p>
