Abstract
A blowing or stretch-blowing machine for preforms made of polymer material. The blowing or stretch-blowing machine () has a plurality of molds () movable on a transport system, in which each of the molds () comprises a first half-mold () and a second half-mold () hinged around a hinge axis () and a bottom plate () adapted to cooperate with the half-molds () for closing the bottom of the mold (), and a mechanism for vertical/translational movement of the bottom plate, to cyclically form a closed cavity adapted to receive a preheated preform and allow expansion, by blowing or stretch-blowing of the preform inside the cavity, to obtain a bottle or container. Each of the molds () comprises a system for synchronized opening/closing of the half-molds () and of the bottom plate () actuated by an actuator thereof () independent from motorization of the machine.
