Abstract: Device for placing films with a specific format in a machine for moulding an object, said films designed to at least partly coat the lateral surface and one extremity face of said object. This device includes:a first magazine (7) containing a plurality of first films (8) each intended to coat one extremity face of said object,a second magazine (9) containing a plurality of second films (10) each intended to coat the lateral surface of said object,a member (14) having an external shape corresponding to that of the object to be coated and able to take from said first (7) and second (9) magazines first (8) and second (10) films,first (24,35) and second (21,36) means to apply and keep in place said first (8) and second (10) films against said member (14), andmeans (27,28) to convey said taking member (14) from the matrix (6) of said machine.

Abstract: This invention relates to a device for positioning a film of determined format, serving as at least a partial coating of the lateral surface of an object, between two pieces of a machine, at least one of said pieces being mobile with respect to the other in a first direction, the machine having a technique for taking the film from a magazine. According to the invention, the film-taking technique uses a member whose outside shape corresponds to the lateral surface of the object to be coated. It also includes a technique for applying the film onto the lateral surface. Further there is provided a technique for conveying the film-taking means, with the film applied on said member, between a position of taking the film from the magazine and a work position between the pieces of the machine.

Abstract: The present invention relates to a machine for molding objects, having male and female mold parts of which at least one is mobile with respect to the other. According to the invention there is included a device for conveying film and a device for conveying a molded object capable of moving in synchronism so that, when the film conveying device is in position of depositing the film between the mold parts, the object conveying device is in position of removal of the object from between the mold parts, and, when the film conveying device is in position of taking of a film for use in a further cycle, the molded object conveying device is in position of evacuation of the object from the mold.

Abstract: This invention relates to a device for transporting a film of determined format from a position where a film is taken from a magazine to a work position between two parts, mobile with respect to each other in a first direction, of a machine. The device includes apparatus for taking a film from said magazine capable of moving, in a movement asociated with that of said parts, in a second direction at right angles to said first direction between said position of taking and said work position, and drive apparatus are associated with said magazine to animate the latter, independently of said parts but in synchronism therewith, by a reciprocating movement parallel to said first direction.

Abstract: This invention relates to a process for manufacturing, by injection of synthetic material, objects comprising a film forming an integral part thereof, by means of an injection machine incorporating a mould comprising a punch and a die, and at least one nozzle for injecting synthetic material, wherein a web of the film material is advanced step by step towards the mould and, after advance of said web by a step corresponding to a certain dimension of the film to be cut out, a film is cut out from said web in the desired format, with the result that the film cut out to the chosen format lies between the punch and the die at the instant when the mould is closed.

Abstract: A system is provided for bringing a film, forming at least a partial coating of a molded object, into a mold. In this system, the transport device includes means for holding the film in position during transport thereof from the waiting position to the working position, and two cooperating members, of the rack or screw type, meshing with each other, the first of which is parallel to the direction of movement of the movable part of the mold and is fixed to one of the parts thereof and the second of which is secured to the means for holding the film in position and may slide in the movable part of the mold.

Abstract: A method, machine and mold are provided for fabricating, by injection of synthetic material, containers having a film forming an external coating. The machine includes a mold, an injection nozzle, a film feed device, and means for holding the film against the male element of the mold; and wherein the injection nozzle is carried by the male element of the mold and said holding means comprise a slider in the cavity of the female element movable, under the action of the male element, against a return force.
