Abstract
Abstract An apparatus for controlling the shape of rolled product characterized in that an image reflected from the surface of the rolled product is detected, that the pressure working on the central and edge portions of the rolling machine is regulated in accordance with the degree of displacement of the image, and that the shape of the rolled product in the process of being rolled is automatically kept uniform.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
86 words
An apparatus for controlling the shape of a rolled product traveling in a longitudinal direction comprising means for projecting a linear image on the surface of the rolled product in the transverse direction thereof, means for detecting the longitudinal deviation of a portion of said linear image at least at the central and end portion of said image, and oil pressure means for regulating the pressure actions on the central and edge portions of the rolled product in accordance with the output of said detecting means.
Claim 2
Independent Claim
86 words
An apparatus for controlling the shape of a rolled product traveling in a longitudinal direction comprising means for projecting a linear image on the surface of the rolled product in the transverse direction thereof, means for detecting the longitudinal deviation of a portion of said linear image at least at the central and end portion of said image, and oil pressure means for regulating the pressure actions on the central and edge portions of the rolled product in accordance with the output of said detecting means.
Claim 3
Independent Claim
107 words
An apparatus for controlling the shape of a rolled product traveling in a longitudinal direction comprising light source means for forming a linear light image on the surface of the rolled product in the direction thereof, a television camera for detecting said images on said rolled product, means for detecting the degree of longitudinal displacement of a portion of said linear light image from its original position at least at the central and edge portions of the rolled product, and oil pressure means for regulating the pressure working on the central and edge portions of the rolled product in accordance with the output of said detecting device.
Claim 4
Independent Claim
107 words
An apparatus for controlling the shape of a rolled product traveling in a longitudinal direction comprising light source means for forming a linear light image on the surface of the rolled product in the direction thereof, a television camera for detecting said images on said rolled product, means for detecting the degree of longitudinal displacement of a portion of said linear light image from its original position at least at the central and edge portions of the rolled product, and oil pressure means for regulating the pressure working on the central and edge portions of the rolled product in accordance with the output of said detecting device.
Claim 5
Independent Claim
106 words
An apparatus for controlling the shape of a rolled product traveling in a longitudinal direction comprising light source means for forming a linear light image on the surface of the rolled product in the transverse direction thereof, photoelectricity conversion means for detecting the degree of displacement to which portions of the image are subjected in accordance with the shape of the rolled product, said conversion means receiving reflected light from at least the central and edge portions of said image, and oil pressure means for regulating the pressure working on the central and edge portions of the rolled product in accordance with said photoelectric conversion means.
Claim 6
Independent Claim
106 words
An apparatus for controlling the shape of a rolled product traveling in a longitudinal direction comprising light source means for forming a linear light image on the surface of the rolled product in the transverse direction thereof, photoelectricity conversion means for detecting the degree of displacement to which portions of the image are subjected in accordance with the shape of the rolled product, said conversion means receiving reflected light from at least the central and edge portions of said image, and oil pressure means for regulating the pressure working on the central and edge portions of the rolled product in accordance with said photoelectric conversion means.
