A blow molding device for blow molding preforms into a predetermined shape. The blow molding device includes a batch-type mold provided with cavities, a heating furnace that heats preforms while the preforms are arranged in series, a transfer machine that simultaneously transfers the preforms as a batch to the cavities of the mold after the preforms are heated and sent out sequentially from the heating furnace, and a pressurized liquid feeder that feeds pressurized liquid to the preforms after the preforms are arranged in all of the cavities of the mold and the mold is closed.

A device for unloading and storing preforms for the production of containers made of plastics includes, comprising at least one cooling plate that defines a plurality of receptacles for respective preforms and means a component for transferring the still-hot preforms from an injection molding device to the cooling plate. The device includes pick-up components adapted to pick up the preforms from the cooling plate and place them inside at least one accommodation container.

A singulation apparatus for preforms, including a device for eliminating mispositioned preforms. The singulation apparatus is designed as a roll-type sorting apparatus that has two conveyor rolls which rotate about parallel axes of rotation, define a common conveying plane, and convey the preforms between the conveying rolls in a direction of travel. The device for eliminating mispositioned preforms is a kick wheel that rotates about an axis of rotation, has a lateral direction of ejection, and meshes with an elimination region above correctly positioned preforms. The kick wheel is concentric with the conveyor rolls and is arranged at a vertical distance above the conveying plane, the axis of rotation of the kick wheel extending substantially in the vertical direction and being inclined by an angle >0 relative to the position extending perpendicular to the conveying plane

A method for ejecting a vessel (12), carried by a transporting device (10), the vessel (12) being provided with a neck (16) including a mouth (18), the transporting device (10) including: a mobile support (28); a gripping mandrel (30) that grips by vertical engagement with the neck (16); an ejection face (64) mounted on the mobile support (28), the gripping mandrel (30) being mounted vertically slidable relative to the ejection face (64) to allow the gripping mandrel (30) to be extracted from the neck (16) when it slides via contact between the ejection face (64) and a bearing face (24) of the neck (16); characterized in that the bearing face (24) of the neck (16) is formed by a shoulder face that protrudes radially towards the outside relative to the mouth (18) and is arranged under the mouth (18) in the vertical direction.

An apparatus (100) for the continuous cycle production of containers from plastic material comprises a metering unit (1) configured to receive from an extruder a flow of molten plastic and to produce a plurality of doses simultaneously from the flow of molten plastic; a forming station (2) includes a plurality of female compression elements (3) for simultaneously receiving the plurality of doses from the plurality of outlets of the metering unit; a plurality of male elements (4) acts in conjunction with the female compression elements (3) to make a plurality of parisons simultaneously by compression moulding; a blow moulding station (5) is configured to receive the parisons of the plurality of parisons and to blow mould the plurality of parisons to form a corresponding plurality of containers.

An inspection and ejector unit for preforms for plastic containers in a transportation line, has at least one driver device which picks up preforms travelling from an inward conveyor device to the inspection and ejector unit, transports them further and passes on at least some of the preforms to an outward conveyor device, at least one detection device by which faulty preforms in the driver device are detected, and at least one ejection device by which preforms which are detected as faulty are removed from the driver device, and a corresponding method.

A system for pre-stretching a preform utilized in forming a container. The system including an oven, a conveyor system configured for transporting preforms through the oven a blow molding station having at least one mold with interior surfaces defining the shape of the container, and a transfer station configured to transfer a preform from the oven into the blow molding station. The system also includes a stretch rod and an actuator. The stretch rod is movable between retracted and extended positions such that, when in the extended position, the stretch rod is positioned interiorly of the preform and the preform is elongated by the stretch rod to form a pre-stretched preform. The stretch rod is located to form the pre-stretched preform prior to the blowing medium being introduced into the preform in the blow molding station.

A method of conveying plastics material pre-forms includes the plastics material pre-forms supplied to a conveying device by a supply device. The conveying device has a first roller body and a second roller body. The plastics material pre-form is conveyed between these roller bodies. A portion of the plastics material pre-forms is supported by the two roller bodies. A further portion of the plastics material pre-forms passes through between the roller bodies. At least one first value characteristic of a state of occupation of the plastics material pre-forms is detected by a first measuring instrument. A second value characteristic is detected by a second measuring instrument downstream of the first measuring instrument in the conveying direction of the plastics material pre-forms. A setting variable of the supply device or the conveying device is controlled on the basis of the two values.

An apparatus for conveying a container made of plastic material comprising supporting frame (3), sliding along a predetermined path; a longitudinal rod (20), defining an axis (X), adapted to translate along said axis and/or to rotate about said axis through guide-holes (24, 25) provided in the supporting frame; a gripping device (22), fixed to a first end of the longitudinal rod, for picking and withholding an end of the container to be conveyed; wherein actuation means are provided for actuating the translation strokes of the longitudinal rod (20) and of the gripping device (22) along said axis (X), so that the gripping device (22) can operate at three working levels or positions: a first resting position (L0), a second gripping position (L1) and a third releasing position (L2).
