Claims35
A shapemeter for measuring flatness of a tensioned metal strip, said strip having a width and traveling in a direction of travel, by measuring distribution of tension across the width of the strip as the strip passes over said shapemeter, said shapemeter comprising:
- A. two spaced apart end blocks;
- B. a support member extending between said end blocks;
- C. a shaft having first and second ends, said shaft having an axis, said axis being generally parallel to said strip and normal to the direction of travel, said first and second ends being respectively rotatably supported by said end blocks;
- D. a plurality of spaced apart resilient members carried by said shaft;
- E. a plurality of measuring rings each disposed adjacent at least one resilient member, each of said measuring rings having a respective outer circumferential surface;
- and
- F. each of said measuring rings having a respective force sensor associated therewith, each respective force sensor carrying a respective pair of spaced apart rotatable support rollers, each respective support roller engaging said outer circumferential surface of the measuring ring associated with said respective force sensor which carries said respective support roller, each respective measuring ring being rotatably supported by said respective pair of support rollers.
A shapemeter for measuring the flatness of a tensioned metal strip, said strip having a width and traveling in a direction of travel, by measuring distribution of tension across the width of the strip as the strip passes over said shapemeter, said shapemeter comprising:
- A. a plurality of spaced apart measuring rings coaxially aligned along an axis, each of said measuring rings having a respective outer circumferential surface;
- B. each of said measuring rings having at least one force sensor associated therewith, each respective force sensor rotatably carrying a respective plurality of spaced apart support rollers, each respective support roller engaging said outer circumferential surface of the measuring ring associated with said respective force sensor which carries said respective support roller;
- C. said respective plurality of support rollers providing primary support for said measuring ring associated with said respective sensor which carries said respective plurality of support rollers.
