ABSTRACT:
A reinforced hose structure is illustrated as including a length of tubing 20 having a first course A of reinforcement braided about the tubing and comprising a conventional braided structure and a second course B of reinforcement braided about the tubing and about the said first course and comprising a conventional braided structure. First course A includes a first group 10 of reinforcing strands applied about the tube in a first helical direction and a second group 12 of reinforcing strands applied concurrently about the tube in a second, helically opposite direction in such a manner as to interlace the strands of the said two groups into a conventional braided structure. Adjacent windings 10, 12 of the first and second groups are spaced apart to provide widened braid spaces which reduce crimping of the edge wires in each group as the groups of wires intersect each other. A plurality of empty unoccupied spaces C are formed in braided course A along the length of the tube. Spaces C are distinct definite spaces as compared to the non-distinct small interstices associated with the interlacing of conventional braided hoses. Second course B of reinforcement includes a third group 14 of reinforcing wires, and a fourth group 16 of reinforcing wires applied concurrently in helically opposite directions about the first course A. The third and fourth groups of wires form a conventional braided structure which generally covers the empty spaces C in the first course.
