ABSTRACT:
An apparatus for adjusting the roller nip in a stand for rolling and/or roll casting. In adjusting the roller nip, the first (lower) bearing housing remains substantially stationary while the second (upper) bearing housing pivots about a pivotal connection located in one of the outer recesses betweeen the first and second bearing housings. The roller nip adjusting means, which is located in the outer recesses between the first and second bearing housings opposite of the pivotal connection, supports a portion of the second bearing housing and can be used to apply a dynamic upward force on the second bearing housing which causes it to pivot and thereby increase the roller nip. The roller nip adjusting means can also be used to decrease the roller nip since when such means are retracted, gravitational forces will cause the second bearing housing to pivot downwardly and remain in indirect or direct contact with the roller nip adjusting means, thereby narrowing the roller nip. A pretensioning force is applied to the bearing housings to restrict widening of the roller nip when rolling stock.
