Abstract
Apparatus for reconfiguring at least three finishing rolls in a plastic sheet fabricating sheetline includes a base, a pair of spaced upright support structures, and pairs of first and second spaced support assemblies. The upright support structures are mounted on the base and support a center one of the rolls in a stationary position therebetween and for totation about a first axis. The first support assemblies support a first outer one of the rolls therebetween for rotation about a second axis and are mounted to the support structures for permitting angularly adjustable movement of the first outer roll relative to the center roll about the first axis to reconfigure the angular position of the first outer roll relative to the center roll. The second support assemblies support a second outer one of the rolls therebetween for rotation about a third axis and are mounted to the support structures for permitting angularly adjustable movement of the second outer roll relative to the center roll about the first axis to reconfigure the angular position of the seocnd outer roll relative to the center roll.
