Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
116 words
A method of manufacturing reinforced flexible thermoplastic hose comprising the steps of extruding a thermoplastic tube, apply
ing a positive, predetermined pressure differ
ence between the inside and outside of the
tube, and applying to the tube reinforcing
elements under tension, in which the re
inforcing elements are heated prior to appli
cation to the tube to such a temperature that the reinforcing elements soften the exterior of the tube and the tension applied to the elements in combination with the pressure difference across the tube causes the elements to penetrate the tube, the pressure difference being maintained while the reinforced assembly is allowed to cool whereby the reinforcing elements are secured to the thermoplastic tube.
Claim 2
Independent Claim
116 words
A method of manufacturing reinforced flexible thermoplastic hose comprising the steps of extruding a thermoplastic tube, apply
ing a positive, predetermined pressure differ
ence between the inside and outside of the
tube, and applying to the tube reinforcing
elements under tension, in which the re
inforcing elements are heated prior to appli
cation to the tube to such a temperature that the reinforcing elements soften the exterior of the tube and the tension applied to the elements in combination with the pressure difference across the tube causes the elements to penetrate the tube, the pressure difference being maintained while the reinforced assembly is allowed to cool whereby the reinforcing elements are secured to the thermoplastic tube.
Claim 3
Dependent Claim
28 words
A method of manufacturing reinforced flexible thermoplastic hose as claimed in claim 1 wherein the pressure difference is removed after cooling below the hardening temperature of the tube.
Claim 4
Dependent Claim
47 words
A method of manufacturing reinforced flexible thermoplastic hose as claimed in claim 1 or claim 2 wherein the positive pressure difference between the inside and the outside of the tube is created by sealing one end of the tube and filling the tube with fluid under pressure.
Claim 5
Dependent Claim
29 words
A method of manufacturing reinforced flexible thermoplastic hose as claimed in claim 3 wherein the fluid may be removed from the tube by applying compressed air to the tube.
Claim 6
Independent Claim
30 words
A method of manufacturing reinforced flexible thermoplastic hose as claimed in any preceding claim comprising the further step of applying an outer cover of thermoplastic material to the completed tube.
Claim 7
Independent Claim
103 words
A method of manufacturing reinforced flexible thermoplastic hose as claimed in any of claims 1 to 4 wherein the initial external diameter of the hose is greater than the desired final external diameter of the reinforcement, such that when the heated reinforcing elements are applied the outer diameter of the hose is greater than the external diameter of the reinforcement, the reinforced hose being passed through heated smoothing means to smooth the exterior surface of the tube, and the pressure difference between the inside and the outside of the hose being removed after smoothing whereby an integrated cover and final hose is formed.
Claim 8
Independent Claim
31 words
A method of manufacturing reinforced flexible thermoplastic hose substantially as hereinbefore described with reference to
Figure 1 or modified as hereinbefore described with reference to Figure 2 of the accompanying drawings.
Claim 9
Independent Claim
31 words
A method of manufacturing reinforced flexible thermoplastic hose substantially as hereinbefore described with reference to
Figure 1 or modified as hereinbefore described with reference to Figure 2 of the accompanying drawings.
Claim 10
Dependent Claim
13 words
A reinforced hose manufactured by a method as claimed in any preceding claim.
