Abstract

The invention relates to a dosing device (8) for dosing plastic material or the like, comprising an extrusion head (10) that has a dispensing opening (12) commonly called a die and a punch (11) extending into the dispensing opening (12), coaxially thereto, for continuously extruding a plastic material in the form of a tubular or annular body, and cutting means (14) for separating a dose of said plastic material in the form of a tubular or annular section. Said device is characterised in that said cutting means (14) consist of at least two elements (16) having at least one sharp or cutting edge, extending on either side of the dispensing opening (12) and secured to driving means generating a symmetrical movement of said elements (15, 16) in relation to the longitudinal axis of the extrudedtubular body until the tubular body is severed by said elements in order to form a dose.

Description

technical field [0001] The invention relates to applications for dosing plastic or similar materials, for any type of cold or hot pasty material such as thermoplastics (PE, PP, PA, etc.) or elastomers (natural or synthetic rubber) Equipment for quantitative feeding. More specifically, the invention relates to a dosing device suitable for use in the production of a unit of a part made of plastic, such as a flexible tube made of plastic comprising a skirt and a shoulder, the flexible tube Obtained from prefabricated tubular bodies. Background technique [0002] As is well known, flexible pipes are generally produced by assembling two parts manufactured separately, namely a cylindrical flexible skirt of predetermined length, and a head. The portion includes a neck having a dispensing orifice and a shoulder connecting the neck to the cylindrical skirt. [0003] Said head, usually made of plastic, can be molded separately and then welded onto one end of the cylindrical skirt, ...
