Abstract

1359037 Extruded reinforced tube SCHIESSER AG 16 June 1971 [16 June 1970] 28245/71 Heading B5A [Also in Division F2] The longitudinally extending reinforcement of a rubber or plastics material hose is delivered, from an annular outlet opening 24 of an extrusion head passage 17 in which it passes through a replaceable annular guide member 18, to the inlet of an annular extrusion die passage 21 at which the rubber or plastics material is delivered, respectively to the exterior and interior of the reinforcement, from annular outlet openings 22, 23 of passages 8, 13<SP>1</SP>, to which the rubber or plastics material is supplied from a crosshead inlet 10 respectively by passage 9, 13<SP>1</SP>. The passage 17 is defined, in the Fig. 1 embodiment, between a bore 2 of the die head and a member 11 which is located therein at a web 11<SP>1</SP>. The reinforcement may comprise fabric or netting of a mesh size either permitting or obdurating penetration thereof by the rubber or plastics, and may comprise a single strip extending circumferentially as a plane spiral or a plurality of strips extending circumferentially in overlapping relationship, and passes through similarly configured passages, of the guide means 181 or 1811, Figs. 3 and 4. The extrusion die passage 21 is defined between a die 3 and a mandrel 16 which is located within the passage 13<SP>1</SP> at radial fins 16<SP>1</SP>, 1611, and secured therein upstream of the inlet of crosshead passage 10, to a member 14 expandably secured by a bolt 15. In the Fig. 2 embodiment (not printed) the passage (17) is defined between the member (11) and a bushing (25) to which it is secured at a radially extending web, and which bushing has an external surface tapered in the downstream direction, at which it is located against a similarly configured die head surface by an annular nut (26) threadedly engaging the die head.
