Abstract
Abstract A hose of elastomeric material has an insert of metal material for making the hose diffusion-proof. To impart plastic memory to the hose, i.e. make it plastically deformable, the insert according to the invention consists of at least two substantially completely overlapping metal foil layers of a ductile metal material which are fully glued and bonded to each other by means of a binder layer.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
79 words
A plastically deformable hose made from elastomeric material and having a plurality of layers, comprising, an inner insert of metal material for making the hose diffusion-proof, said insert of metal material including at least two substantially completely overlapping metal foil layers which make the hose plastically deformable so as to have a plastic memory, each of said metal foil layers being formed of a ductile metal material, and a polyethylene binder layer bonding said foil layers to each other.
Claim 2
Dependent Claim
79 words
A plastically deformable hose made from elastomeric material and having a plurality of layers, comprising, an inner insert of metal material for making the hose diffusion-proof, said insert of metal material including at least two substantially completely overlapping metal foil layers which make the hose plastically deformable so as to have a plastic memory, each of said metal foil layers being formed of a ductile metal material, and a polyethylene binder layer bonding said foil layers to each other.
Claim 3
Dependent Claim
22 words
Hose as claimed in claim 1, wherein the insert of metal foil layers is also bonded to adjacent layers of the hose.
Claim 4
Dependent Claim
17 words
Hose as claimed in claim 1, wherein the metal foil layers are wound with substantially full overlap.
Claim 5
Dependent Claim
14 words
Hose as claimed in claim 1, wherein the metal foil layers are helically wound.
Claim 6
Dependent Claim
30 words
Hose as claimed in claim 1, wherein the insert of metal foil layers is bonded to the surrounding layers of the hose by means of a heat-weldable or heat-activated binder.
Claim 7
Dependent Claim
32 words
Hose as claimed in claim 1, wherein the insert of metal foil layers is disposed between an inner hose layer of elastomeric material and an outer reinforced hose layer of elastomeric material.
Claim 8
Dependent Claim
29 words
Hose as claimed in claim 1, wherein the metal layers comprise a plastically deformable metal material chemically compatible with the surrounding elastomeric layers or provided with a protective layer.
Claim 9
Dependent Claim
24 words
Hose as claimed in claim 7, wherein the metal foil layers are selected from the group consisting of aluminum, aluminum alloys, and brass alloys.
