A print registration system for a beverage can decorator includes an axial registration system and a circumferential registration system. Each registration system is independent and includes a slider that is translated by a motorized lead screw. Axial movement of the axial registration slider is transmitted to axial adjustment of the plate cylinder by a mechanical connection between the axial registration slider and the plate cylinder shaft. Translation of the circumferential registration slider is transmitted to a helical gear mounted to the plate cylinder shaft such that the plate cylinder shaft is rotated by the movement of the circumferential registration slider upon engagement of the helical driven gear with a stationary drive gear.

An oscillating roller system for a beverage can decorator is driven back and forth by a cam follower. A cam body having a cam is mounted to a frame of the inker system. Three oscillating cam roller assemblies are positioned about the cam body. Rotation of the cam oscillates the cam followers for each one of the oscillating rollers. Bearings of the oscillating roller assemblies includes an inlet gallery and outlet gallery for a closed loop lubrication system. The rollers are water cooled.

An over-varnish unit and mandrel pre-spin system for a can decorator, especially for beverage can bodies, can have a mandrel pre-spin belt that is outside of the over-varnish unit housing. The position of the can infeed on the mandrel wheel and the print point is controlled.

The invention relates to an apparatus and method for cutting, printing or embossing a continuous sheet of material. The apparatus comprises a tool element, at least two anvils, which are co-operable with the tool element, and a phase adjustment device. The tool element is configured to have a constant surface speed during operation of the apparatus. The apparatus is adapted to receive the continuous sheet at a constant speed into the apparatus, and being adapted to output the continuous sheet at a constant speed from the apparatus. The phase adjustment device is operable to adjust a speed of the continuous sheet within the apparatus in order to adjust a phase of alternate parts of the continuous sheet to be cut, printed or embossed by each anvil as it co-operates with the tool element.

In order to reduce variations in pressing force of a printing nip to make the printing pressure uniform, an apparatus that performs printing on a substrate using a roll-to-roll method according to an aspect of the present application includes: an ink supply member that supplies a printing ink; a blanket cylinder (30) that transfers part of the ink, which has been supplied from the ink supply member and applied on a surface of the blanket cylinder, onto the substrate; a roller mold (40) that removes part of the ink applied on the surface of the blanket cylinder (30); a base (46) on which the blanket cylinder (30) is fixed; a slider (44) that supports the roller mold (40) and moves on the base (46); a moving resistance reduction device (80) that reduces a moving resistance of the slider (44) relative to the base (46); and a roller mold nip device (42) that applies, to the roller mold (40), a nip pressure against the blanket cylinder (30).

A control apparatus of a web processing system that executes predetermined processing onto a web continuously existing along a movement passage, in which the web processing system includes a rotating body that rotates while being in contact with the web, and the control apparatus controls a rotation speed of the rotating body such that a circumferential speed of the rotating body at a contact surface with the web matches a transport speed of the web.

An over-varnish unit and mandrel pre-spin system for a can decorator, especially for beverage can bodies, can have a mandrel pre-spin belt that is outside of the over-varnish unit housing. The position of the can infeed on the mandrel wheel and the print point is controlled.

According to examples, an apparatus may include a first feed element and a second feed element, in which a web is to be fed to the first feed element and from the first feed element to the second feed element. The apparatus may also include a controller that may determine whether the web exiting the second feed element is shifted from an intended position and based on a determination that the web is shifted from the intended position, cause the first feed element to be moved laterally a first distance and the second feed element to be moved laterally a second distance to compensate for the shift in the web exiting the second feed element.

An oscillating roller system for a beverage can decorator is driven back and forth by a cam follower. A cam body having a cam is mounted to a frame of the inker system. Three oscillating cam roller assemblies are positioned about the cam body. Rotation of the cam oscillates the cam followers for each one of the oscillating rollers. Bearings of the oscillating roller assemblies includes an inlet gallery and outlet gallery for a closed loop lubrication system. The rollers are water cooled.

An apparatus, a printing press and method for correcting the printing position of a printing unit of a printing press that has at least one sensor unit, where the method incudes the steps of detecting an actual position of at least one print mark via the sensor unit, where the print mark is printed onto a printing material via the printing unit, determining of a deviation of the detected actual position from a setpoint position, determining at least one difference value that characterizes the deviation, determining a buffer value from a number of basic values previously stored in a memory, determining a correction value by subtracting the buffer value from the difference value, storing the determined correction value in the memory as one of the basic values, and correcting the printing position based on the determined correction value.
