Abstract: A paper folding assembly (15) with a plurality of rotatable rollers (18) including a cutting cylinder (60) with a cutting cylinder body (76) mounted for rotation with a rotary drive shaft (66) and having cutting members (84A, 84B) for cutting a paper ribbon (19) into individual paper sheets (24) and folding members (82A, 82B) for creasing the individual sheets (24) into a rotatable jaw cylinder (50) to create a lap (20) between opposed edges (22, 23), a cutting cylinder lap adjustment apparatus (70) with an end plate (62) secured to the folding members (82A, 82B) and mounted to the rotary drive shaft (66) adjacent an end (72) of the cutting cylinder body (76), a plurality of cutting members (84A, 84B) secured to the cutting cylinder body (76) which is mounted for rotary movement around the rotary drive shaft (66) and an adjusting member (90) connected to the cutting cylinder body (76) to move the cutting members (84A, 84B) at different selected angular positions relative to the rotary drive shaft (66) to chan

Abstract: A hydraulically driven die carrier for a power press, the carrier comprising a bolster for carrying a die; a set of wheels supporting the bolster for horizontal rolling movement to position the die horizontally; a separate hydraulic drive motor for each of the wheels; a plurality of hydraulic lift cylinders for moving the bolster vertically relative to the wheels; and a hydraulic control system for operating the hydraulic drive motors and lift cylinders for horizontal rolling and vertical movement of the die carrier, the control system including a supply pump having two separate outputs for providing separate sources of pressurized hydraulic fluid for the hydraulic drive motors and for the lift cylinders; a reservoir of hydraulic fluid connected to the pump; valve means for connecting and disconnecting the separate sources of hydraulic fluid and the respective drive motors and lift cylinders; and means for locking the lift cylinders in their raised positions while the cylinders are disconnected from the suppl
