Abstract
Abstract Apparatus for measuring stress distribution across the width of a flexible strip travelling in the direction of its length, comprising a pick-up deflector roller having a plurality of rings, encased in a tire of flexible material, the edges of the rings being cut away to produce local stress in the tire as compared with a smooth cylindrical roller.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
99 words
Apparatus for measuring stress distribution across the width of flexible strip travelling in the direction of its length, of the kind comprising a pick-up deflector roller comprising a plurality of closely laterally adjacent rings running with the strip, the strip being angularly deflected under tension, said rings being encased in a common outer cover or tyre comprising a flexible elastic synthetic or natural material, and the peripheral edges of adjoining rings are cut away and the resulting local recesses, as compared with a smooth cylindrical roller surface, are at least partially filled by the material of the outer tire.
Claim 2
Dependent Claim
99 words
Apparatus for measuring stress distribution across the width of flexible strip travelling in the direction of its length, of the kind comprising a pick-up deflector roller comprising a plurality of closely laterally adjacent rings running with the strip, the strip being angularly deflected under tension, said rings being encased in a common outer cover or tyre comprising a flexible elastic synthetic or natural material, and the peripheral edges of adjoining rings are cut away and the resulting local recesses, as compared with a smooth cylindrical roller surface, are at least partially filled by the material of the outer tire.
Claim 3
Dependent Claim
13 words
Apparatus according to claim 1, wherein the edges of the rings are chamfered.
Claim 4
Dependent Claim
23 words
Apparatus according to claim 1, wherein O-rings of synthetic material are inserted into the edge regions of relatively adjacent rings, which are chamfered.
Claim 5
Dependent Claim
37 words
Apparatus according to claim 1, in which, in the region of the edges of adjacent rings, the tyre is provided with external incisions which extend through part of its wall thickness leaving the inner wall region intact.
Claim 6
Dependent Claim
16 words
Apparatus according to claim 1, wherein the tyre has wall thickness between 5 and 20 mm.
Claim 7
Dependent Claim
13 words
Apparatus according to claim 1, wherein the tyre is moulded around the roller.
Claim 8
Dependent Claim
16 words
Apparatus according to claim 1, wherein the tyre is formed by winding foils around the roller.
Claim 9
Dependent Claim
18 words
Apparatus according to claim 1, wherein the tyre is formed on the roller by layerwise polymerisation or vulcanising.
Claim 10
Dependent Claim
10 words
Apparatus according to claim 1, wherein the tyre is fibre-reinforced.
Claim 11
Dependent Claim
21 words
Apparatus according to claim 1, wherein the outer edges of the outermost rings at the roller ends are also cut away.
Claim 12
Dependent Claim
13 words
Apparatus according to claim 3, wherein the O-rings are of hollow tubular form.
