A printing apparatus has a printing cylinder rotatably supported by a main frame. A subassembly contains a plurality of anilox rolls rotatable about parallel spaced-apart axis with the subassembly being rotatable about an axis parallel to and between these spaced-apart axes. A locking arrangement secures the subassembly in selected positions whereby any selected one of the anilox rolls can be brought into an operative position for cooperating with the printing cylinder for printing. Alternative ink systems supply ink to the selected anilox roll when in the operative position. Preferably the subassembly is supported at its ends by gear casings which are adjustably rotatably mounted in a subframe which itself is pivotally mounted in the main frame. The ink rolls may be anilox rolls with different surface screens.

A printing apparatus has a plurality of ink rolls, particularly anilox rolls, for a single printing cylinder at any one of a number of similar and serially arranged printing stations, each station having one ink roll at a time being selected for use in cooperation with either a wipe roll assembly or a doctor blade assembly associated with each station. The various assemblies are surrounded by respective movable cover members which allow the assemblies to either print, or be washed or cleaned, at the same time that a similar printing or cleaning operation is taking place at an adjacent printing station. A movable subframe adjacent the main frame carries the ink rolls and their associated movable cover members as well as both the wipe roll assembly and the doctor blade assembly. Preferably, the subframe is translated with respect to the main frame to upper and lower positions to thereby effect either the printing or cleaning operations, and all the operative assemblies on the subframe may be disposed above the print cylinder carried by the main frame.

A printing apparatus includes a rotatable anilox roll engageable with a rotatable print cylinder for transferring ink thereto. A rotatable wipe roll and a doctor blade head are selectively engageable with different portions of the anilox roll to provide alternative wipe roll and doctor blade inking systems. Preferably both inking systems have substantially common ink supply and ink return paths with a valve being selectively operable to direct the ink supply path to either the wipe roll or the doctor blade head. Facilities for effecting a wash cycle may be provided to wash either inking system after use. Preferably an interlock arrangement prevents changing in use between the two inking systems until a wash cycle has been completed.

A machine or machine section for squaring folded container blanks has a conveyor for conveying slotted and partially folded container blanks. A folding device completes folding of each container blank while being conveyed by the conveyor. A gauge plate is inserted in a slot in each of the slotted and partially folded container blanks. A mechanism moves the gauge plate in timed sequence with the conveyor, inserts the gauge plate in the slot before completion of folding of the respective blank in order to "square" the folded blank, and then withdraws the gauge plate from the slot. Overlapping flaps of each folded blank may be tacked together during "squaring" by drops of hot melt adhesive which subsequently hold the flat folded blanks square while the conventional slow drying water soluble glue dries. The "squaring" arrangement may be incorporated in a conventional gluer/folder machine.

Cross cuts for forming the ends of a tab on a sheet, for example a glue tab on a corrugated paperboard container blank, are performed by independent rotary cutter units. Each cutter unit has a spirally convoluted blade which, as it rotates, cuts progressively inwards from an outside edge of the sheet towards an opposite outside edge. As the sheet is conveyed along, a downstream cutter unit cuts the leading end of the tab, and an upstream cutter unit cuts the trailing end. After each cut, the cutter remains at rest with its blade in an inoperative position out of the path of any oncoming sheet. A sensor senses the next oncoming sheet and initiates the cutting via a computer. These rotary cutters mitigate skewing of the sheets while being cut.
