Abstract: An in-line method for marking a substrate made of extruded synthetic material, the method including the steps of extruding the synthetic material through an extrusion die to form the substrate, marking the substrate by scrolling the substrate obtained from the extrusion die between two rotatably mounted and temperature-controlled rollers with an upper roller and a lower roller, one of the rollers having an impression forming the negative of a decoration or a texture to be marked on one face of the substrate, this same roller or the other of the rollers including at least one notch allowing to guide the substrate as it passes through the extrusion die and between the two rollers. An installation can include in line the extrusion die and the marking device.

Abstract: A method of fabrication of a wristband of a watch or piece of jewelry, including: providing a first synthetic material; providing an extrusion line with a die plate for making an extrudate from the first material; providing one or more additional materials distinguished in their properties from the first material; providing a die plate including a first zone defining a profile allowing for fabrication of an extrudate having a hollow tubular profile at least at one of its ends in which the extrudate has a width corresponding to the length of one or two strands of the wristband; the die plate further includes a second zone allowing defining of particular profiles selected from among a flat profile, a curved profile, or a profile with projecting zones.

Abstract: The invention concerns a cap liner (9) comprising: a middle layer made of a plastic material with gas barrier effect; first and second outer layers comprising each a polyolefin resin and arranged on either side of the middle layer; an intermediate polyethylene layer, placed between the middle layer and each of the outer layers, the intermediate layers being designed to protect the middle layer against moisture and to prevent degradation of said middle layer gas barrier properties. The cap liner can be placed in a cap near its transverse wall or towards the free end of its skirt or on a container neck. It can be planar or thermoformed. The invention also concerns methods for producing a neck-joint cap assembly.

Abstract: The invention concerns a closure device for a carboy designed for a liquid dispenser of the water fountain type. The device comprises a cap (3) including a transverse wall (5) wherefrom projects an outer skirt (6). The transverse wall has, on its inner surface (29), an annular groove (30) coaxial with the cap, delimited by two ribs (31, 32) projecting from the transverse wall. The groove is designed to receive a cast or moulded joint (34), and to prevent the displacement thereof parallel to the transverse wall. The groove can also include on its inner surface means for catching said joint.
