A device for printing on hollow bodies comprises a mandrel wheel and a segment wheel. The mandrel wheel has its own motor separate from a motor of the segment wheel. In association with the segment wheel, along a circumferential line thereof, a plurality of plate cylinders are positioned or at least are positionable radially against this segment wheel. An inking unit is associated with each plate cylinder. Each plate cylinder, and a roller arranged in the associated inking unit, are each driven in rotation independently by a motor. The motor of the mandrel wheel and the motor of the segment wheel and the motor of the relevant plate cylinder and the motor of the roller arranged in the associated inking unit are connected to one another for data exchange by a common data bus. The relevant motors each have their own drive controller and their own power part connected to the data bus. Control data for the relevant motors, transported via the data bus, form a virtual guide axis.

A rotary screen transfer printing machine and a control system thereof. The rotary screen transfer printing machine having a feeding unit, a printing unit, a drying unit, and a receiving unit; the printing unit has at least one rotary screen transfer printing assembly and a guide belt assembly; each rotary screen transfer printing assembly has a rotary screen plate roller and a transfer roller; the rotary screen plate roller is close to the transfer roller; the transfer roller is seamlessly coated with rubber or a resin having good affinity for a water-based ink. A control system includes: a motion controller; a conveying synchronization module, used for controlling the feeding unit, the printing unit, the drying unit, and the receiving unit to synchronize the conveying speeds of the four units; and a rotary screen transfer printing synchronization module.

Please add the Abstract of the Disclosure, as set forth on the separate accompanying sheet. This Abstract of the Disclosure is essentially the same, in content, as the Abstract which is a part of the published PCT application, WO 2020/187665 A1. No new matter is being presented by the addition of this Abstract of the Disclosure.

A device for the alphanumeric labeling of printed products comprises a shaft mounted in a frame, and around which shaft at least one wheel-shaped or ring-shaped labeling tool is rotatably mounted, which tool carries a number of alphanumeric characters, one behind the other, on its outer circumference. A drive motor, in the form of, for example, a stepper motor, is provided and by which the labeling tool can be rotated around the shaft. The drive motor is linked for signals transmission to one of a data processing and a data storage of a control device, in which an assignment specification between the working positions of the alphanumeric characters or the fields carrying the alphanumeric characters, and step numbers of the stepper motor, is provided. The drive motor is or can be controlled by the control device in terms of a number of steps to be traveled, using this provided assignment specification, to move an alphanumeric character to be printed or the relevant field into a working position.

Disclosed is a flexographic printing device for a laminating machine, including at least one pair of shoulders mounted on a trolley frame, a blade chamber for containing printing ink; an Anilox roller that rotates in contact with the printing ink, a print roller holding a printing cliché that rotates in contact with the Anilox roller and a counter-pressure roller that rotates in contact with the cliché held by the print roller, wherein at least the Anilox roller and the print roller are supported by respective supports that can slide with respect to the shoulders in a direction substantially orthogonal to their axes, the printing device also including at least one first motor for rotating the Anilox roller, at least one second motor for rotating the print roller and possibly a third motor for rotating the counter-pressure roller.

A device for printing on hollow bodies includes a segmented wheel. A system is used for sequentially supplying the hollow bodes to the periphery of the segmented wheel. That system includes at least one conveyor wheel and one mandrel wheel. The conveyor wheel, the mandrel wheel, and the segmented wheel are arranged in a transport direction of the hollow bodies. A plurality of driving elements are arranged on the periphery of the conveyor wheel, and a plurality of holding elements are arranged on the periphery of the mandrel wheel. Each holding element receives a respective hollow body to be printed in cooperation with the segmented wheel. The mandrel wheel and the conveying wheel each have their own drive, each of which drive is separate from a drive of the segmented wheel.

A method is disclosed, which method is or at least can be carried out in a flexographic printing press for the purpose of determining a position of mutual contact between a printing roller and at least one counter roller. An average position of mutual contact between the printing roller and the counter roller is calculated, based on every position of mutual contact between the printing roller and the counter roller that is determined for a specific angular position of the printing roller and is used to execute a printing process carried out by the flexographic printing press.
