Abstract: The invention relates to a half-mold comprising a joint face; an opposing assembly face), where the longitudinal cross-section of the assembly face is in the form of an arc of a circle centered on a reference axis. The reference axis is offset longitudinally towards the front relative to the joint face. The invention also concerns a molding assembly, a molding unit and a forming facility comprising such half-molds. The invention also concerns a method for producing such half-molds and a method for producing a surface for receiving such half-molds.

Abstract: Disclosed is a method for the preferential heating of a thermoplastic hollow body having at least one portion to be heated and another to be superheated, the portion that is to be superheated initially having a radiation absorption coefficient substantially identical to that of the portion to be heated. The method includes, in succession: a first step of marking the portions of the hollow body that are to be superheated, during which step isolated marks are made in the thickness of the wall of the portion that is to be superheated so as to increase its absorption coefficient; a second step of preferential heating of the hollow body by uniform exposure of the portions that are to be heated and of the portions that are to be superheated to the heating electromagnetic radiation. Also disclosed is a preform marked in accordance with the first step of the method.

Abstract: Disclosed is a method for manufacturing packaging including a container. The method includes: an operation of forming the container via blow molding or stretch blow molding from a plastics preform, an operation of treating an inner surface of the container, during which a thin barrier layer is formed on the inner surface via plasma-enhanced chemical vapor deposition; an operation of printing on an outer surface of the container, during which ink is deposited on the outer surface to form a decorative and/or informative inscription thereon.

Abstract: Disclosed is a device and a method for sterilizing thermoplastic containers using a pulsed beam of electrons which is formed of a succession of pulses each having an emission time which is less than 100 ns and an intensity which is greater than 1 kA so as to sterilize, through a wall of the container, at least the inside of the container. A reflector mounted with the ability to move axially relative to the container is included.

Abstract: The installation includes a conveyor system having at least one conveyor provided with two conveyor bodies having active strands that are parallel to each other for receiving and transporting articles that are arranged successively between the active strands. One of the conveyor bodies has a natural leather material, at least on the active part thereof in direct contact with the items. The conveyor bodies have belts that are at least partially or fully formed using leather.

Abstract: The device includes several rails supported by a frame (17) which form a kind of tunnel for the end of the preforms, on the neck (21) side. The tunnel is twisted and the two rails (12) and (13) which act as a guidance under the neck have a separation which is constant between the entrance (4) and the exit (5) of the tunnel in order to convey diverse and varying preforms. One of the rails, the rail (12), is straight and the other rail, the rail (13), is curved, this curved rail (13) having a profile created in accordance with the type of preform to be conveyed. The straight rail (12) corresponds to the edge of a guide (15) in the form of a simple flat which is fixed to the frame (17), and the curved rail (13) also corresponds to the edge of a guide (16) in the form of a simple flat which is also fixed suitably to the said frame (17).
