Abstract: A carton blank processing machine is disclosed having rolls for printing, cutting, creasing and otherwise processing carton blanks. The processing rolls are driven by shafts extending into bearings supported by spaced-apart frame members. At least one shaft extends through its associated bearing to the outboard side of the frame member and is surrounded by a motor, preferably of the frameless type, having a hollow rotor in which the shaft is received and connected for direct drive by the rotor. Axial adjustment systems are provided for axially adjusting at least one shaft and roll, and such systems may be mounted on the outboard end of the frameless motor.

Abstract: A sheet processing apparatus, for example for flexographic printing and die-cutting of corrugated paperboard container blanks, has first and second successive processing sections connected by a transfer section. The sheets are successively passed through the various sections in positional registrations therewith. A sensor senses a sheet while in the transfer section and provides a signal representative of the positional registration of the sheet in the transfer section. A computer system determines from the signal whether the sheet would enter the second section in correct positional registration for processing by the second section, and adjusts as necessary the positional registration of the sheet while in the transfer section to cause the sheet to enter the second section in correct positional registration therewith.
