Abstract
Abstract An improved coating roller, particularly for use in coating photographic compositions onto webs, including a tubular generally-cylindrical roller member and a tubular generallycylindrical insert shrink-fitted into the roller member, such that the interference interface between the members dampens vibrations imparted to the roller. Prior to insertion the OD of the insert is approximately equal to the ID of the roller member within a tolerance of + OR - 0.001 inches. The insert extends axially within the outer member so that at least fifty percent of the inner surface of the roller member is frictionally engaged by the outer surface of the insert.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
141 words
A coating roller for transporting a moving web into contact with a ribbon of coating material discharging from a coatiNg hopper adapted for depositing such coating material onto the web, said coating roller comprising: a metallic tubular roller member having end portions, a generally-cylindrical outer surface adapted to contact and transport a web, and a generally-cylindrical inner surface defining a cavity between said end portions, journal means coupled to each end portion of said roller member for mounting said roller for rotation about the axis of its outer surface, and a metallic tubular insert member positioned within the cavity of said roller member and having a generally-cylindrical outer surface in frictional engagement with at least 50 percent of the inner surface of the roller member to form an interface between said frictionally engaged surfaces that dampens vibration in the roller member.
Claim 2
Dependent Claim
141 words
A coating roller for transporting a moving web into contact with a ribbon of coating material discharging from a coatiNg hopper adapted for depositing such coating material onto the web, said coating roller comprising: a metallic tubular roller member having end portions, a generally-cylindrical outer surface adapted to contact and transport a web, and a generally-cylindrical inner surface defining a cavity between said end portions, journal means coupled to each end portion of said roller member for mounting said roller for rotation about the axis of its outer surface, and a metallic tubular insert member positioned within the cavity of said roller member and having a generally-cylindrical outer surface in frictional engagement with at least 50 percent of the inner surface of the roller member to form an interface between said frictionally engaged surfaces that dampens vibration in the roller member.
Claim 3
Dependent Claim
177 words
A coating roller for transporting a moving web into contact with a ribbon of coating material discharging from a coating hopper adapted for depositing such coating material onto the web, said coating roller comprising: a metallic tubular roller member having end portions, a generally-cylindrical outer surface adapted to contact and transport a web, and a generally-cylindrical inner surface defining a cavity between said end portions, journal means coupled to each end portion of said roller member for rotatably mounting said roller member rotation about the axis of its outer surface, and a metallic tubular insert member positioned within the cavity of said roller member and having a generally-cylindrical outer surface substantially equal in diameter to the diameter of the inner surface of said roller member and extending axially within the cavity of the roller member such that the outer surface of the insert member is in frictional engagement with at least 50 percent of the inner surface of the roller member to form an interface between said frictionally engaged surfaces that dampens vibration in the roller member.
Claim 4
Dependent Claim
177 words
A coating roller for transporting a moving web into contact with a ribbon of coating material discharging from a coating hopper adapted for depositing such coating material onto the web, said coating roller comprising: a metallic tubular roller member having end portions, a generally-cylindrical outer surface adapted to contact and transport a web, and a generally-cylindrical inner surface defining a cavity between said end portions, journal means coupled to each end portion of said roller member for rotatably mounting said roller member rotation about the axis of its outer surface, and a metallic tubular insert member positioned within the cavity of said roller member and having a generally-cylindrical outer surface substantially equal in diameter to the diameter of the inner surface of said roller member and extending axially within the cavity of the roller member such that the outer surface of the insert member is in frictional engagement with at least 50 percent of the inner surface of the roller member to form an interface between said frictionally engaged surfaces that dampens vibration in the roller member.
Claim 5
Dependent Claim
52 words
A coating roller according to claim 2 wherein the outer diameter of the insert member is substantially equal to the inner diameter of the roller member within a tolerance of + or - 0.001 inch, such that said insert member is held in position in said roller member by a frictional fit.
