Abstract

1384545 Flexible hose DUNLOP Ltd 17 April 1972 [21 April 1971] 10341/71 Heading F2P A method of manufacturing a flexible hose comprises the steps of: (a) advancing a mandrel past means for applying a strip of vulcanizable sheet rubber so as to form a longitudinal seam, (b) helically wrapping at least two layers of strip reinforcing material about the inner lining by advancing the mandrel past the wrapping means, (c) wrapping a temporary supporting cover around the hose structure, (d) vulcanizing the assembly so formed. As described a sheet of vulcanizable synthetic rubber 11 is formed round a mandrel by contoured rolls 13, 14 as the mandrel is fed between the rolls, excess material 17 being cut off by the co-operation of the rolls. Helical reinforcement strips 20 are applied from reels 18, 19 and further reinforcement 20 is applied in the opposite sense from reels 21, 22. An outer cover 23 of vulcanizable sheet rubber is applied from roll 24 in a manner similar to that of the inner liner 11 and a wrapper 27 of wet nylon strip is then applied. After curing in an autoclave the wrapper 27 is removed. The reinforcement strips 20 may comprise a plurality of longitudinally extending members of nylon filaments supported on a strip of non- woven matrix material formed of interconnected nylon filaments, the reinforcing members being embedded in elastomeric material to maintain them securely in a predetermined relationship (e.g. as disclosed in Specification 1,356,791). The reinforcement may be applied as described in Specification 1,033,547, and may be of the kind disclosed in Application No. 10342/71. The vulcanizable rubber sheet from which the inner and/or outer layer(s) are wrapped is preferably callendered sheet between 15-25 thousandths of an inch thick. The sheet may be laminated and have a poorer quality of rubber adjacent the reinforcement strips 20 than faces the surface of the hose.
