A method for producing a by means of steel cord reinforced rubber hose, and by a steel cord a reinforced rubber hose

摘要

A method for producing a rubber hose (10) which, by means of a plurality of helical steel cord (12) is reinforced. The rubber hose (10) has an inner tube (10), an external pipe (24) and a layered reinforcing layer (14), which is between the inner tube and the outer tube is provided. The reinforcing layer (14) is formed by individual layers (90, 96) are stacked on top of each other. For the formation of the reinforcing layer (14), a composite strip material (26) is formed by a large number of reinforcing steel cord (12) in a strip of uncured rubber (38) are embedded in such a way that they extend in its longitudinal direction, and subsequently, the cord material strip (26) spirally around the inner tube (11) and vulcanized wound. The respective individual layers (90, 96) are made of the composite strip material (26) is formed, which a single continuous shape, and each layer (90, 96) is formed by alternately one of the winding formation step for winding up of the composite strip material (26) in a first forward winding direction and a winding formation step for winding up of the composite strip material (26) in a second forward winding direction opposite to the first forward winding direction are repeated.
