Abstract:
1. A machine for blowing or stretch-blow moulding of bottles or containers having a plurality of moulding units, each moulding unit comprising a lateral first half-shell and a second half-shell, hinged about a hinge pin having a hinge axis, and a bottom cooperating with said first half-shell and second half-shell in order to cyclically form a closed cavity suitable for receiving a pre-heated pre-form and for allowing the expansion by blowing or stretch blow moulding of the pre-form inside the cavity so as to obtain a bottle or container, said moulding unit being arranged to cyclically assume a closed mould configuration and an open mould configuration towards and away from a closure plane X-X passing through said hinge axis, said mould unit comprising opening and closing elements of the half-shells and handling elements of the bottom, wherein: said half-shells and said bottom are actuated by said opening and closing elements of the half-shells and handling elements of the bottom in a synchronized manner starting from a single motion inlet comprising a single cam coupling; and said half-shells are configured to rotate about said hinge axis concurrently with a translation of said hinge axis along the plane X-X in a direction that is substantially perpendicular to the hinge axis itself.
