Abstract

A roller assembly for a stand of a torsionless finishing block of a multi-stand rolling mill for producing continuous wire from a round elongated rod is disclosed. The assembly is characterized by the provision of at least one bearing mounted on the drive shaft between the rollers and the drive shaft of the stand, whereby the stand is operable to calibrate the finished wire. Alignment devices are provided for longitudinally centering the bearing relative to the stand roller and circlips connect the bearing with the roller in the centered position. Spacing elements are mounted on the drive shaft at opposite ends of the bearing to longitudinally position the bearing relative to the shaft. In the absence of a finished wire to be calibrated, the rollers are driven at the speed of rotation of the drive shaft. When finished wire enters the stand and comes in contact with the rollers, the rollers rotate at the speed of rotation of the wire.
