Abstract: A dosing device for dosing plastic material, comprising an extrusion head that has a dispensing opening commonly called a die and a punch extending into the dispensing opening, coaxially thereto, for continuously extruding a plastic material in the form of a tubular or annular body, and a cutter for separating a dose of said plastic material in the form of a tubular or annular section. The cutter includes at least two elements having at least one cutting edge extending on either side of the dispensing opening and secured to a driver for symmetrically moving the at least two elements in relation to a longitudinal axis of the extruded tubular body until the tubular body is severed by said at least two elements in order to form a dose.

Abstract: A device for manufacturing and/or treating components such as flexible tubes from prefabricated tubular bodies includes at least means for supporting the components and means for moving the components in line with a plurality of work stations. The device includes transport means along a main closed path for a plurality of satellite turrets rotatingly mounted on the transport means. The satellite turrets include means for holding a plurality of components, and each satellite turret is rotated by a predetermined angle around its rotation axis when the satellite turret reaches at least one predetermined point of the main path.

Abstract: The invention relates to a process for manufacturing plastic packaging in tubular form, which process comprises a wrapping step during which a laminate (11) is wrapped, an abutting step during which the edges (8, 9) of the laminate (11) are butted together and a fastening step during which said edges (8, 9) of the laminate (11) are welded together, characterized in that a bead (12) of plastic in the molten state is extruded and deposited on the internal face of the packaging so as to cover at least the weld zone (10) defined between the edges. The energy needed to produce the weld (10) comes from the plastic bead (12). The invention also relates to packaging obtained from the aforementioned process and to a device for implementing said process.

Abstract: The invention relates to a method for automatically packaging empty collapsible tubes (1), that are supplied by a conveyor belt, into a plurality of packaging containers that take up collapsible tubes (1). According to the invention, the supplied collapsible tubes (1) are collected in a row without gaps, supplied in this row to an intermediate storage (13) and then jointly transferred into a packaging container; thereafter the packaging container is conveyed further on. The empty collapsible tubes (1) are arranged in conveyor trays (3) of a feeder belt (2) and are collected continuously in a row or partial row by means of separately driven and adjustable suction vees (5).

Abstract: Installation for assembling tube components, particularly bodies (1) with shoulders, comprising the following elements arranged in succession: a linear body conveyor (4), a transfer system (7) designed to apply a change in orientation to the bodies (1) of about 90°, an assembly unit (8) for fixing the shoulders to the bodies (1), characterized in that the transfer system (7) consists of a device (9) for gripping the bodies and of a device (17) for changing the orientation of the bodies, the orientation-change device comprising a rotary conveyor (17), of the conveyor belt type, which is arranged at right angles to the direction of the linear conveyor (4), the said rotary conveyor (17) comprising a belt (18, 19) rotating about a direction that makes an angle of about 45° with the direction of the linear conveyor (4), the belt (18, 19) comprising elements (15) for grasping the bodies, the shape of which is designed so that the bodies (1) are initially grasped on one of the sides of the rotary conveyor (17), in a
