Abstract
Abstract A process for the measurement of the longitudinal stresses prevailing across metal bands which are under longitudinal tension, by subjecting the bands to transverse deflection at different spots and determining the magnitude of the deflection which are a direct measure of the tensions within the different zones. The deflection is produced by mechanical means, i.e., a knocking device, gas or liquid bursts, acoustical or magnetoelectrical means.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
98 words
A method for measuring the deviations of the tensile stress at an edge of a rapidly moving thin metallic tape under hightensile stress with respect to a mean reference tensile stress, comprising the steps of, applying to at least one zone of said tape near one edge portion of a major tape surface a deflection force having a magnitude operating in a direction transverse to the longitudinal direction of said tape thereby deflecting said tape in said transverse direction; and measuring the magnitude of said deflection from the other surface of the opposite major surface near said zone.
Claim 2
Independent Claim
98 words
A method for measuring the deviations of the tensile stress at an edge of a rapidly moving thin metallic tape under hightensile stress with respect to a mean reference tensile stress, comprising the steps of, applying to at least one zone of said tape near one edge portion of a major tape surface a deflection force having a magnitude operating in a direction transverse to the longitudinal direction of said tape thereby deflecting said tape in said transverse direction; and measuring the magnitude of said deflection from the other surface of the opposite major surface near said zone.
Claim 3
Dependent Claim
46 words
The method as claimed in claim 1, the step of measuring the magnitude further comprising, allowing fluid to issue under slight pressure from a nozzle positioned near the opposite major surface and near said zone of said tape, and measuring changes in pressure in said fluid.
Claim 4
Dependent Claim
22 words
The method as claimed in claim 1, wherein said deflection force is applied intermittently by a burst of fluid under high pressure.
Claim 5
Dependent Claim
22 words
The method as claimed in claim 1, wherein said deflection force is applied continuously by a stream of fluid under high pressure.
