Abstract

1,172,176. Dusting extruded tubing. SEMPERIT OSTERREICHISCH - AMERIKANISCHE GUMMIWERKE A.G. 28 March, 1968 [30 March, 1967], No. 14913/68. Heading B5A. An extrusion machine having a ring die 8 and mandrel 11 for the production of a tube 10, e.g. of rubber or plastics, is equipped with dusting apparatus comprising an axial nozzle 12 through which a powder/air mixture is fed and a coaxial bore 16 through which excess powder/air mixture is withdrawn. This arrangement allows the downstream end of the tube to be collapsed during dusting and therefore a greater length of continuous tubing to be produced. The functions of nozzle 12 and bore 16 may be reversed. In a second embodiment, Figs. 3 and 4 (not shown), divergent entry and exit nozzles (12, 4) are provided. Nozzle (12) is closed, apart from a narrow, e.g. 1-1À5 mm. wide, adjustable annular passageway, by a stop (3) which acts as an atomizer. Dimensions (D 1 , D 2 , D 3 ), Fig. 4 (not shown), are preferably such that (D 2 ) is greater than both (D 1 ) and (D 3 ), thereby preventing premature removal of the mixture. A suction producer (5) is described which is connected to nozzle (4) by suction line (7) and to the compressed air source (17) for nozzle (12).
