Abstract
Abstract A guidance system for guiding a relatively wide metal strip and one or more relatively narrow metal strips to be roll bonded as they travel to the bonding rolls for accurately laying the narrow strip or strips on the wide strip. It comprises a carriage mounted for lateral sliding movement relative to the path of the strips, the wide strip and the narrow strip or strips being guided through the carriage for travel to the bonding rolls. The carriage is movable laterally in response to lateral deviation of the wide strip from a vertical longitudinal reference plane accurately to maintain the narrow strip or strips in position relative to the wide strip. It also acts in response to variations in the width of the wide strip accurately to maintain the narrow strip or strips in position relative to a side edge of the wide strip.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
176 words
Apparatus for guiding a first metal strip and a second metal strip narrower than the first to lay the second strip on top of the first in accurately located position thereon while the strips are travelling in the direction of their length to a set of squeeze rolls for bonding the strips together, said apparatus comprising a carriage mounted for lateral sliding movement relative to the path of the strips, means carried by the carriage for supporting the first strip for travel thereover toward said rolls, means carried by the carriage engageable with the opposite side edges of the first strip, and means on the carriage above the path of the first strip for supporting and guiding the second strip for travel in a vertical plane between the side edges of the first strip, said carriage being slidable laterally in response to lateral deviation of the first strip from a vertical longitudinal reference plane to move the carriage laterally so as to maintain the second strip in accurately located position with respect to the first strip.
Claim 2
Dependent Claim
176 words
Apparatus for guiding a first metal strip and a second metal strip narrower than the first to lay the second strip on top of the first in accurately located position thereon while the strips are travelling in the direction of their length to a set of squeeze rolls for bonding the strips together, said apparatus comprising a carriage mounted for lateral sliding movement relative to the path of the strips, means carried by the carriage for supporting the first strip for travel thereover toward said rolls, means carried by the carriage engageable with the opposite side edges of the first strip, and means on the carriage above the path of the first strip for supporting and guiding the second strip for travel in a vertical plane between the side edges of the first strip, said carriage being slidable laterally in response to lateral deviation of the first strip from a vertical longitudinal reference plane to move the carriage laterally so as to maintain the second strip in accurately located position with respect to the first strip.
Claim 3
Dependent Claim
64 words
Apparatus as set forth in claim 1 wherein said means engageable with the opposite side edges of the first strip comprises means at one side of the carriage mounted in fixed position on the carriage and means at the opposite side of the carriage movable laterally relative to the carriage and biased in the direction toward the respective side edge of the first strip.
Claim 4
Dependent Claim
100 words
Apparatus as set forth in claim 2 wherein said means at one side of the carriage comprises a pair of side rolls rotatable on vertical axes spaced longitudinally of the carriage and said means at the opposite side of the carriage comprises a single side roll rotatable on a vertical axis between the transverse planes of the vertical axes of said pair of rolls, and having means mounting said single side roll for movement laterally of the carriage, and spring means biasing said roll mounting means to move in the direction toward the respective side edge of the first strip.
Claim 5
Dependent Claim
35 words
Apparatus as set forth in claim 3 wherein the means for supporting the first strip comprises rolls carried by the carriage below the body of the carriage rotatable on horizontal axes transverse to the carriage.
Claim 6
Dependent Claim
61 words
Apparatus as set forth in claim 4 wherein the carriage has a top plate thereon having at least one guide groove extending longitudinally thereof in its top surface for guiding a said second strip, said top plate being inclined downward from the end of the carriage away from the squeeze rolls to the end of the carriage toward the squeeze rolls.
Claim 7
Dependent Claim
23 words
Apparatus as set forth in claim 5 wherein said top plate is removable from the carriage for replacement thereof with another top plate.
Claim 8
Dependent Claim
31 words
Apparatus as set forth in claim 5 wherein the carriage has side blocks extending downwardly therefrom at opposite sides thereof, said blocks carrying said strip supporting rolls and said side rolls.
Claim 9
Dependent Claim
22 words
Apparatus as set forth in claim 7 wherein the carriage is slidable on fixed supports extending transversely with respect to the strips.
