Abstract: The invention concerns a machine for manufacturing plastic items comprising, in series, along the manufacturing line: a rotatable roll (1) of plastic material in the form of at least one strip; a shaper (4) for forming tubes from said strips and means (5) for longitudinally welding said tubes; means (6) for cutting the tubes transversely, arranged so as to form tube sections (10); means for transferring and depositing said sections in holding and moving means; an oven (8) in which said tube sections move; a first turret (9) supporting moulds; means for processing the tube sections in the first turret; means for blowing a pressurised fluid into the moulds; a second turret (14) for discharging the bottles from said moulds.

Abstract: A mold comprising at least two mold portions, at least one of which includes a vent opening out to the inside of the cavity and to the outside of the mold and presenting a flow section that is predetermined to enable air to be exhausted when the mold is closed. Said mold portion comprises at least two parts that extend over an entire dimension of the mold cavity and that are assembled together, the parts being held apart from each other by at least one spacer so as to define between them a gap that opens out to the inside of the cavity and to the outside of the mold in order to form the vent. A blow-molding machine including such a mold.

Abstract: A machine is provided for blow-molding articles from a strip of material. The machine has a mount with two frames mounted thereon. Each frame is connected to a movement actuator so as to be movable along a path of the strip between respective positions that are upstream and downstream relative to a travel direction of the strip through the machine. A pipe, a holder member, and a mold are mounted respectively on an item selected from the mount and the frames. A control unit is connected to the movement actuators to control them in such a manner as to generate a sequence of moving the guide pipe and the mold relative to the holder member and of opening and closing the mold in such a manner as to cause the strip to advance along the rectilinear path.
