Abstract
Abstract The freely rolling rolls are provided with distance wheels at the respective ends. Alternating rolls are provided with distance wheels which are fixedly mounted to the roll bodies while the remaining rolls are provided with distance wheels which are rotatably mounted on the roll bodies. The adjacent distance wheels are also provided with interengaging V-shaped grooves and projections for lateral stability of the rolls. The distance wheels provide for a constant uniform spacing of the rolls and maintain the rolls in parallel relation.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
134 words
An apparatus for guiding and supporting a continuously cast slab comprising an elongated support surface, and a plurality of rolls disposed on said support surface in freely rolling relation to travel along said support surface and to guide a slab therealong, each said roll having an axis of rotation perpendicular to the direction of travel along said support surface and having a distance wheel with an axis of rotation coextensive with said axis of rotation of said roll mounted at each end of each roll in contact with a distance wheel of an adjacent roll, said distance wheels of each alternating roll being fixedly mounted thereon and non-rotatable relative to their associated alternating roll and the remainder of said rolls having said distance wheels rotatably mounted thereon for rotation relative to their associated roll.
Claim 2
Independent Claim
134 words
An apparatus for guiding and supporting a continuously cast slab comprising an elongated support surface, and a plurality of rolls disposed on said support surface in freely rolling relation to travel along said support surface and to guide a slab therealong, each said roll having an axis of rotation perpendicular to the direction of travel along said support surface and having a distance wheel with an axis of rotation coextensive with said axis of rotation of said roll mounted at each end of each roll in contact with a distance wheel of an adjacent roll, said distance wheels of each alternating roll being fixedly mounted thereon and non-rotatable relative to their associated alternating roll and the remainder of said rolls having said distance wheels rotatably mounted thereon for rotation relative to their associated roll.
Claim 3
Dependent Claim
25 words
An apparatus as set forth in claim 1 which further comprises a rolling bearing mounting each respective rotatably mounted distance wheel on a respective roll.
Claim 4
Dependent Claim
41 words
An apparatus as set forth in claim 1 wherein alternating distance wheels on each side of said rolls each have a circumferential groove therein and the remaining wheels have a circumferential projection engaging in said groove of an adjacent distance wheel.
Claim 5
Dependent Claim
20 words
An apparatus as set forth in claim 1 wherein each said groove is V-shaped and each said projection is V-shaped.
Claim 6
Independent Claim
159 words
An apparatus for guiding and supporting a continuously cast slab comprising a frame; a curved support surface disposed in said frame and having a plurality of laterally spaced support elements thereon; and a plurality of rolls disposed on said support elements in freely rolling relation to travel along said support support surface and to guide a slab therealong, each of said rolls having an axis of rotation perpendicular to the direction of travel along said support surface and a pair of distance wheels with axes of rotation coextensive with said axis of rotation of said roll mounted one on a respective end thereof, each alternating roll of said rolls having said pair of distance wheels thereon fixedly mounted on a respective end thereof and being non-rotatable relative to their associated alternating roll and the remainder of said rolls having said pair of distance wheels thereon rotatably mounted on a respective end thereof for rotation relative to their associated roll.
Claim 7
Independent Claim
159 words
An apparatus for guiding and supporting a continuously cast slab comprising a frame; a curved support surface disposed in said frame and having a plurality of laterally spaced support elements thereon; and a plurality of rolls disposed on said support elements in freely rolling relation to travel along said support support surface and to guide a slab therealong, each of said rolls having an axis of rotation perpendicular to the direction of travel along said support surface and a pair of distance wheels with axes of rotation coextensive with said axis of rotation of said roll mounted one on a respective end thereof, each alternating roll of said rolls having said pair of distance wheels thereon fixedly mounted on a respective end thereof and being non-rotatable relative to their associated alternating roll and the remainder of said rolls having said pair of distance wheels thereon rotatably mounted on a respective end thereof for rotation relative to their associated roll.
Claim 8
Dependent Claim
30 words
An apparatus as set forth in claim 5 which further comprises means associated with said frame for recycling rolls exiting said support surface to an entrance to said support surface.
Claim 9
Dependent Claim
41 words
An apparatus as set forth in claim 5 wherein alternating distance wheels on each side of said rolls each have a circumferential groove therein and the remaining wheels have a circumferential projection engaging in said groove of an adjacent distance wheel.
Claim 10
Dependent Claim
173 words
An apparatus as set forth in claim 5 which further comprises a second support surface facing said first support surface and having a plurality of laterally spaced support elements thereon, and a second plurality of rolls disposed on said support elements of said second support surface in freely rolling relation to travel along said support support surface and to guide a slab therealong, each of said second plurality of rolls having an axis of rotation perpendicular to the direction of travel along said support surface and a pair of distance wheels with axes of rotation coextensive with said axis of rotation of said roll mounted one on a respective end thereof, each alternating roll of said second plurality of rolls having said pair of distance wheels thereon fixedly mounted on a respective end thereof and being non-rotatable relative to their associated alternating roll and the remainder of said second plurality of rolls having said pair of distance wheels thereon rotatably mounted on a respective end thereof for rotation relative to their associated roll.
Claim 11
Dependent Claim
38 words
An apparatus as set forth in claim 8 which further comprises means associated with said frame for re-cycling rolls of said second plurality of rolls exiting said second support surface to an entrance to said second support surface.
Claim 12
Dependent Claim
14 words
An apparatus as set forth in claim 5 wherein each said roll is cylindrical.
