Soft rubber roll cover with wide grooves
View Patent ↗An industrial roll includes: a substantially cylindrical metallic core; a base layer that is adhered to and circumferentially overlies the core; and a top stock layer that circumferentially overlies the base layer. The top stock layer includes circumferential grooves, wherein the grooves have a width/height ratio of at least 0.7.
1. An industrial roll, comprising:
a substantially cylindrical metallic core;
a base layer that is adhered to and circumferentially overlies the core; and
top stock layer that circumferentially overlies the base layer;
wherein the top stock layer comprises a material having a Pusey and Jones (P&J) hardness of 35 or higher;
wherein the to stock layer further comprises blind drilled holes;
wherein the top stock layer includes circumferential grooves, and wherein the grooves have a width/height ratio of at least 0.7.
2. The industrial roll defined in claim 1 , wherein the top stock layer comprises rubber.
3. The industrial roll defined in claim 1 , wherein the material comprising the top stock layer has a Poisson's ratio of at least 0.35.
4. The industrial roll defined in claim 1 , wherein the top stock layer further comprises through holes.
5. The industrial roll defined in claim 1 in combination with a Yankee can of a papermaking machine.
6. The industrial roll defined in claim 1 in combination with a Yankee can of a papermaking machine.
7. An industrial roll, comprising:
a substantially cylindrical metallic core;
a rubber base layer that is adhered to and circumferentially overlies the core; and
a rubber top stock layer that circumferentially overlies the base layer, the material comprising the topstock layer having a Pusey and Jones (P&J) hardness of 35 or higher;
wherein the to stock layer further comprises through holes;
wherein the top stock layer includes circumferential grooves, and wherein the grooves have a width/height ratio of at least 0.7.
8. The industrial roll defined in claim 7 , wherein the material comprising the top stock layer has a Poisson's ratio of at least 0.35.
9. The industrial roll defined in claim 7 , wherein the top stock layer further comprises blind drilled holes.
10. The industrial roll defined in claim 7 in combination with a Yankee can of a papermaking machine.
11. An industrial roll, comprising:
a substantially cylindrical metallic core;
a base layer that is adhered to and circumferentially overlies the core; and
a top stock layer that circumferentially overlies the base layer, the material comprising the top stock layer having a Poisson's ratio of at least 0.35;
wherein the top stock layer includes circumferential grooves, and wherein the grooves have a width/height ratio of at least 0.7.
12. The industrial roll defined in claim 11 , wherein the top stock layer comprises rubber.
13. The industrial roll defined in claim 11 , wherein the top stock layer comprises a material having a Pusey and Jones (P&J) hardness of 35 or higher.
14. The industrial roll defined in claim 11 , wherein the top stock layer further comprises blind drilled holes.
15. The industrial roll defined in claim 11 , wherein the top stock layer further comprises through holes.
16. An industrial roll, comprising:
a substantially cylindrical metallic core;
a base layer that is adhered to and circumferentially overlies the core; and
a top stock layer that circumferentially overlies the base layer, the material comprising the top stock layer having a Pusey and Jones (P&J) hardness of 35 or higher;
wherein the to stock layer includes circumferential grooves, and wherein the grooves have a width/height ratio of at least 0.7.
