Abstract: A tool for use in combination with an annular roll fixed on the end of a shaft by means of a sleeve axially inserted in wedged engagement therebetween. The tool includes a hydraulically actuated piston-cylinder assembly having an axially extending mounting stem which is adapted to be received in detachably interlocked engagement within an axial blind bore in the end of the shaft. The cylinder is rotatable on the stem to adjust the tool between sleeve removal and sleeve inserting positions. When in the sleeve removal position, the piston bears against the shaft end and the cylinder engages and removes the sleeve. When in the sleeve insertion position, the cylinder is checked against a stop on the mounting stem and the piston urges the sleeve into wedged engagement between the roll and the shaft.

Abstract: A rolling mill laying head has a first tubular shaft mounted on first bearings for rotation relative to a stationary housing structure. A second hollow shaft carrying a three dimensionally curved laying pipe is mounted on second bearings for rotation relative to the first hollow shaft. Both hollow shafts are rotatably driven in the same direction at different speeds.

Abstract: A portable carrier module for transporting work rolls and entry and exit guides to and from a cantilevered roll stand in a rolling mill. The carrier module remains removably mounted on the roll stand during the rolling operation, and includes integral roll cooling means automatically coupled to water supply conduits extending through the roll stand housing.
