Abstract
Abstract A plurality of juxtaposed rings are rotatably mounted on a stationary axle and are engageable by said strip and adapted to deflect the same. A plurality of bearings surround said axle and are surrounded each by one of said rings. Each of said bearings comprises an inner race facing said axle. A plurality of springs surround said axle and are surrounded each by said inner race of one of said bearings. Each of said spring rings has a mounting portion secured to said axle and an engaging portion which is opposite to said mounting portion and has a radially inner side and a radially outer side, which engages the associated inner race. A plurality of pressure gages are provided, each of which is disposed between said axle and said engaging portion of one of said spring rings and engages said engaging portion on the radially inner side thereof.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
162 words
A roller assembly having strip-deflecting and strip tensionmeasuring properties, comprising a stationary axle, a plurality of juxtaposed rings rotatably mounted on said axle and having each a strip-contacting and deflecting portion, a plurality of bearings, each of which surrounds said axle and is surrounded by one of said rings and comprises an inner race facing said axle, a plurality of spring rings, each of which surrounds said axle and is surrounded by said inner race of one of said bearings and has a mounting portion secured to said axle and an engaging portion which is opposite to said mounting portion and has a radially inner side and a radially outer side, which engages the associated inner race adjacent to said strip-contacting portion of the associated deflecting ring, and a plurality of pressure gages, each of which is disposed between Said axle and said engaging portion of one of said spring rings and engages said engaging portion on the radially inner side thereof.
Claim 2
Dependent Claim
162 words
A roller assembly having strip-deflecting and strip tensionmeasuring properties, comprising a stationary axle, a plurality of juxtaposed rings rotatably mounted on said axle and having each a strip-contacting and deflecting portion, a plurality of bearings, each of which surrounds said axle and is surrounded by one of said rings and comprises an inner race facing said axle, a plurality of spring rings, each of which surrounds said axle and is surrounded by said inner race of one of said bearings and has a mounting portion secured to said axle and an engaging portion which is opposite to said mounting portion and has a radially inner side and a radially outer side, which engages the associated inner race adjacent to said strip-contacting portion of the associated deflecting ring, and a plurality of pressure gages, each of which is disposed between Said axle and said engaging portion of one of said spring rings and engages said engaging portion on the radially inner side thereof.
Claim 3
Dependent Claim
58 words
A roller assembly as set forth in claim 1, in which said axle is formed with oblique flats on circumferentially opposite sides of each of said pressure gages and overload-preventing stop means are mounted on said flats and engageable by said spring rings to limit the deformation thereof so as to prevent an overloading of said spring rings.
Claim 4
Dependent Claim
55 words
A roller assembly as set forth in claim 1, in which each of said pressure gages comprises a coil, an armature extending into said coil, a displacement-transmitting pin connected to said armature, spring means urging said pin away from said coil, and an annular stop limiting the movement of said pin away from said coil.
Claim 5
Dependent Claim
117 words
A roller assembly as set forth in claim 3, in which each of said pressure gages comprises a housing which carries said annular stop and in which said displacement-transmitting pin is movably mounted, a plurality of radially extending, threaded fasteners are provided, which are threaded into said axle, each of said housings being secured to said axle by at least one of said threaded fasteners, and a plurality of coiled compression springs are provided, each of which surrounds one of said threaded fasteners and is compressed between the associated one of said housings and said axle, whereby said fastener is operable to adjust the position of said housing in a radial direction with respect to said axle.
Claim 6
Dependent Claim
63 words
A roller assembly as set forth in clalim 1, which comprises a straightedge-mounting structure carried by said axle, a straightedge mounted on said mounting structure and extending in the longitudinal direction of said axle radially outwardly of said deflecting rings and facing the same and, means for moving said straightedge into engagement with all said deflecting rings to provide a reference position thereof.
Claim 7
Dependent Claim
63 words
A roller assembly as set forth in clalim 1, which comprises a straightedge-mounting structure carried by said axle, a straightedge mounted on said mounting structure and extending in the longitudinal direction of said axle radially outwardly of said deflecting rings and facing the same and, means for moving said straightedge into engagement with all said deflecting rings to provide a reference position thereof.
