Abstract: A roller leveler is provided with mechanisms to continuously sense and to measure roller deflection and to automatically correct the deflection based on the degree of deflection sensed. The sensing mechanisms are mounted on a structure which is isolated from the forces of deflection acting on the rollers and may comprise mechanical, electromechanical, electronic, sonar, optic, fiber optic, fluid, or laser devices. Novel back-up rolls are also provided to correct the deflection.

Abstract: A fork lift mechanism is associated with apparatus for palletizing long sheets of strip material at the discharge end of a shearing press. The long sheets are palletized on an underlying conveyor having a width corresponding to the length of the sheets in the direction of discharge from the press. The fork lift mechanism is supported above the conveyor for displacement toward and away from the shearing press in the direction of the discharge and is adapted to be elevated and lowered relative to the conveyor. The fork lift mechanism is operable to receive and support a plurality of short sheets from the press to form a stack on the fork lift mechanism and to position a plurality of such stacks on a pallet on the conveyor and in side-by-side relationship on the pallet in the direction of press discharge and/or in the direction of conveyor movement.

Abstract: A clamping collar is provided to be mounted about a shaft, arbor or the like, which may be secured at any position along the longitudinal axis of the shaft and preferably adjacent to the load on the shaft. The device comprises a pair of interfaced rings concentric about the shaft and arcuately shiftable one with respect to the other to shift locking lugs radially into and out of clamping engagement with the shaft. The device also includes means to make lateral pressure contact with arbor spacing sleeves, washers, spacers or flanges assembled on the shaft to space tool means, or the like, therebetween.
