A manufacturing process for flexible tube skirts including the steps of providing a multi-layer plastic film, cutting out a strip from the multi-layer plastic film, producing a cylindrical sleeve by rolling-welding the strip, and cutting out the sleeve to the desired length to obtain the tube skirts. The strip is cut out from a multi-layer plastic film which has a symmetrical structure in relation to its median plane, with symmetrical layers having the same thickness and made of the same plastic, having the same chemical composition and the same molar mass.

Method of manufacturing laminated flexible tubes

A hinged-lid closure equipped with a lid and a base including a plate, an attachment skirt and an external lateral skirt, where the attachment skirt is thicker than the plate and the external lateral skirt. The base is equipped with a radial longitudinal rib attached to an internal surface of the external lateral skirt and located in a plane mid-perpendicular to the hinge.

Lightweight hinged-lid closure for a flexible tube

A method for decorating the cylindrical walls of receptacles, comprising the following steps: a) moveable mandrels are arranged in a loop and are displaced, keeping their axes parallel to a direction D; b) each receptacle is engaged by the cylindrical wall thereof on the mandrel; c) the mandrel is brought into the vicinity of a marking cylinder which turns about a fixed axis parallel to direction D; d) the mandrel is rotated at a speed which is correlated with that of the marking cylinder; e) a transfer film support strip is displaced between the marking cylinder and the mandrel; f) the marking cylinder and mandrel are placed in contact with each other such that the marked area of the transfer film adheres to the cylindrical wall; g) the support strip is removed from the cylindrical wall of the receptacle. The inventive method is adapted to the manufacture of flexible tubes and can be easily implemented on existing devices such as capping machines.

Process allowing cylindrical-walled containers to be decorated at a fast rate

Apparatus for manufacturing flexible tubes comprising a skirt and a head provided with a neck and a shoulder linking the neck to the skirt, the apparatus having a first zone devoted to manufacturing the skirts, a second zone devoted to manufacturing the flexible tubes, a third zone devoted to finishing the flexible tubes thus produced, a first transfer device transferring the skirts in continuous motion from the first zone to the second zone, and a second transfer device transferring, in continuous motion synchronized with the former, the tubes from the second zone to the third zone. The second zone has a third transfer device for transferring the punches in continuous motion synchronized with that of the first transfer device and with that of the second transfer device, loading device for loading the skirts on the punches associated with the synchronized movement of said first and third transfer devices, and unloading devices for freeing the punches from the tubes covering them for associated with the synchronized movement of the second and third transfer devices.

Manufacturing apparatus for flexible plastic tubes

The invention relates to a method for producing objects and object parts formed by an assembly comprising at least two plastic parts (and' and&#x2032;), which can move in relation to one another with at least one degree of freedom and which are provided with surfaces having at least partially complementary shapes such that, in at least one geometric configuration, they are solidly interconnected on a common surface (&#x2032;) in close, clearance-free contact The inventive method comprises the following steps: 1) molding of a first part (&#x2032;) by compression or injection; 2) removal of the second tool, the first part (&#x2032;) remaining solidly connected to the first tool which serves as a piece of support equipment or is installed on a piece of support equipment (); 3) compression molding of the second part using the whole () of the first part which is integral to the support equipment and a third tool; 4) removal of the first support tool () and the third tool () and extraction of the assembly () thus formed.
