Abstract
Abstract A guide roll assembly for effecting lateral displacement of running strip from an offset to a centered position and for compensating for any tendency of the strip to run askew. A pair of rolls are carried by a frame which is pivoted for movement in a horizontal plane about the centerline of the exiting strip. The entry roll is tilted in coordination with its lateral displacement.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
162 words
A steering roll assembly for correcting deviation of a running strip from a desired path of travel, comprising: a fixed base; a subframe pivotally connected at one end thereof to said base; first and second rolls carried by said subframe said first roll being mounted adjacent the end of said subframe remote from said pivotal connection for pivotal motion about an axis perpendicular to the longitudinal axis of said roll at the midpoint thereof, said second roll being mounted on said subframe with its longitudinal axis perpendicular to the longitudinal axis of said subframe and with its cylindrical surface tangent to the axis of the pivotal connection between said subframe and said base; means carried by said fixed base for effecting the pivotal motion of said subframe; means for effecting the pivotal motion of said first roll relative to said subframe; and sensing means detecting the position of the incoming strip, said sensing means controlling the operation of said subframe pivoting means.
Claim 2
Dependent Claim
162 words
A steering roll assembly for correcting deviation of a running strip from a desired path of travel, comprising: a fixed base; a subframe pivotally connected at one end thereof to said base; first and second rolls carried by said subframe said first roll being mounted adjacent the end of said subframe remote from said pivotal connection for pivotal motion about an axis perpendicular to the longitudinal axis of said roll at the midpoint thereof, said second roll being mounted on said subframe with its longitudinal axis perpendicular to the longitudinal axis of said subframe and with its cylindrical surface tangent to the axis of the pivotal connection between said subframe and said base; means carried by said fixed base for effecting the pivotal motion of said subframe; means for effecting the pivotal motion of said first roll relative to said subframe; and sensing means detecting the position of the incoming strip, said sensing means controlling the operation of said subframe pivoting means.
Claim 3
Dependent Claim
26 words
Apparatus according to claim 1 further characterized in that said means for pivoting said first roll operates in coordination with said means for pivoting said subframe.
Claim 4
Dependent Claim
37 words
Apparatus according to claim 2 further characterized in that said means for pivoting said first roll is adjustable to vary the amount of pivoting of sAid first roll relative to the amount of pivoting of said subframe.
Claim 5
Dependent Claim
37 words
Apparatus according to claim 2 further characterized in that said means for pivoting said first roll comprises: a platform supporting said first roll and pivoting therewith; and a linkage arrangement connecting said platform and said fixed base.
Claim 6
Dependent Claim
45 words
Apparatus according to claim 4 further characterized in that said platform pivots in a plane normal to the bisector of the angle between the centerline of the incoming path of travel and the centerline of the path of travel between said first and second rolls.
Claim 7
Dependent Claim
74 words
Apparatus according to claim 5 further characterized in that said linkage arrangement comprises a projecting portion of said platform extending along the longitudinal centerline of said subframe; a crossmember slidably received on said projecting portion of said platform and extending on either side thereof; and at least one link, one end of said link being pivotally connected to said crossmember, and the opposite end of said link being pivotally connected to said fixed base.
Claim 8
Dependent Claim
24 words
Apparatus according to claim 5 further characterized in that said link may be connected to said crossmember at any of a plurality of points.
Claim 9
Independent Claim
124 words
A device for correcting lateral deviations of a running strip from a desired path of travel, comprising: an entry roll; an exit roll spaced from said entry roll; a subframe supporting said entry and exit rolls; said subframe being capable of pivotal motion about an axis on the centerline of said desired path of travel and tangent to the exit side of said exit roll; a fixed base supporting said subframe; means for detecting the deviation of the incoming strip from the desired path of travel; and means responsive to said detecting means for moving said subframe and for simultaneously pivoting said entry roll relative to the subframe about an axis perpendicular to the longitudinal axis of the entry roll at the midpoint thereof.
Claim 10
Independent Claim
124 words
A device for correcting lateral deviations of a running strip from a desired path of travel, comprising: an entry roll; an exit roll spaced from said entry roll; a subframe supporting said entry and exit rolls; said subframe being capable of pivotal motion about an axis on the centerline of said desired path of travel and tangent to the exit side of said exit roll; a fixed base supporting said subframe; means for detecting the deviation of the incoming strip from the desired path of travel; and means responsive to said detecting means for moving said subframe and for simultaneously pivoting said entry roll relative to the subframe about an axis perpendicular to the longitudinal axis of the entry roll at the midpoint thereof.
Claim 11
Dependent Claim
32 words
A device according to claim 8 wherein said means for moving said subframe and pivoting said entry roll moves said entry roll in the opposite direction to the motion of said subframe.
Claim 12
Dependent Claim
73 words
A device according to claim 9 further characterized in that said entry roll is mounted on said subframe for pivotal motion about an axis perpendicular to the longitudinal axis of said roll at the midpoint thereof and coincident with the bisector of the angle between the centerline of the incoming path of travel of the strip and the centerline of the path of travel of the strip between said entry and exit rolls.
Claim 13
Dependent Claim
43 words
A device according to claim 10 further characterized in that said means for moving said subframe and pivoting said entry roll includes a support for said entry roll pivoting therewith, and a linkage arrangement interconnecting said entry roll support and said fixed frame.
Claim 14
Dependent Claim
34 words
A device according to claim 11 further characterized in that said linkage arrangement is adjustable to vary the amount of pivotal motion of said entry roll relative to the pivotal motion of said subframe.
Claim 15
Dependent Claim
106 words
A device according to claim 8 wherein said means for moving said subframe and pivoting said entry roll includes means for sensing the position of said subframe relative to said fixed base, a hydraulic cylinder mounted on said fixed base and having its operational end connected to said subframe, a hydraulic relay supplying hydraulic fluid under pressure selectively to one or the other of the sides of the piston of said hydraulic cylinder, and actuating means responsive to said means for detecting the deviation of the incoming strip and to said means for sensing the position of said subframe, said actuating means controlling said hydraulic relay.
