An installation () for thermally conditioning thermoplastic preforms () that are intended to be formed, the installation () including:&#x2014;a thermal-conditioning zone () divided vertically into a heating first part () which is intended to house a body () of the preform () and a cooling second part () which is intended to house a neck () of the preform ();&#x2014;a device () for cooling a portion of the preform () by producing a stream of gas passing through the thermal-conditioning zone (); characterized in that the cooling device () produces a blade () of gas blown with laminar flow through an axial outlet slit ().

Installation for thermally conditioning preforms with one portion of the preform being cooled by a blown blade of air

A device for blowing, with the aid of a pressurized fluid, containers from thermoplastic blanks closed in a blow mold including a nozzle whose end is functionally and sealingly connected to the neck of the blank and includes several solenoid valves for selectively connecting the nozzle to the source of a moderately pressurized pre-blowing fluid, to the source of a highly-pressurized blowing fluid and to an exhaust for discharging the pre-blowing/blowing fluid, respectively. The inventive device also includes a body which is mechanically associated with the nozzle, incorporates at least one reception area for receiving a solenoid valve and is selectively connectable to the nozzle.

A rail element conveys suspended objects, such as bottles or preforms. The rail element includes two guide rails which are separated by a pre-defined distance and which form lateral support surfaces for the objects being conveyed along a conveyor passageway, such as preform sub-neck guides. A helically-curved conveyor section consists of a frame on which the guide rails are helically arranged. At least one guide rail includes a flat band that can be removed from the frame.

Rail element for conveying suspended objects, preform-supply device comprising one such element and curved flat band which can be fixed to one such element

A molding device for blow molding recipients made of a thermoplastic material, including a mold having two mold halves which are movable with respect to each other and provided with a locking device extending along the total height of the mold halves and including two respective hooks, which are oriented toward each other, two respective recesses adjacent to the hooks and a rotatable gib adjacent to the hook and interacting with the other hook in such a way that the two mold-halves are locked in the closed position thereof or are released from each other, the gib being inserted into the recess.

Molding device for producing thermoplastic containers

A moulding device for the production of containers in thermoplastic material, by blowing or blow-drawing, including a mould with two mould halves mutually mobile and provided with a locking device with two lock elements extending over the total height of the respective mould halves and provided with a number of projecting fingers in catches spaced at intervals, one lock element being fixed on one mould half and the other lock element sliding on the other mould half under the action of an actuator device.

Molding device for the production of containers in thermoplastic material

A molding device for the production of containers in thermoplastic material by blowing or blow-drawing, including a mold with two mold halves mutually mobile and provided with a locking device with first and second lock elements, in the form of catches, extending over the whole height of the respective mold halves and a projecting wing on one mold half, including a rotation surface on which a mobile piece is applied over the whole height thereof which includes the second lock element, such that, on blowing, the forces are taken by said mobile piece over the height of the mold by means of the rotation surface.

Moulding device for the production of containers in thermoplastic material

The invention concerns a molding unit for an extrusion-blow molding machine comprising a mold in two parts, each mold-half ( ) being borne by a moveable support ( ), and of the type in which the molding unit ( ) comprises, between at least one of the mold-halves ( ) and the associated support ( ), compensating means ( ) which push the mold-half transversely toward the other mold-half, characterized in that the mechanism ( ) for moving the supports is linked to at least said associated support ( ), by means of elastically deformable means that are suitable for compensating for the deformation of the support ( &lsqb;sic&rsqb;, ), created by the forces exerted by the compensating means ( ).

Molding unit and extrusion-blow molding machine equipped therewith

The invention proposes a molding unit comprising a mold in two parts, each mold-half ( ) being borne by a support ( ), of the type in which the two supports can be moved between an open position and a closed position, in which the supports are connected to each other by locking means, and of the type in which the molding unit comprises fluid pressure compensating means that push transversely at least one of the mold-halves ( ) toward the other, characterized in that the fluid pressure compensating means are realized in the form of an inflatable flexible cushion ( ) interposed between one rear face of the mold-half ( ) and one front face of the associated support ( ).
