A processing unit, for example a printing unit, for the rotational processing of a web-shaped or sheet-shaped substrate, includes a machine frame, at least a first processing cylinder movably mounted in the machine frame, a second processing cylinder stationarily mounted in the machine frame, and a pair of support members associated with each respective processing cylinder. Each support member of the second processing cylinder has an annular segment, a linear guide, a guide body fixed to the machine frame and a manipulator. Each annular segment contacts a respective support member of the first processing cylinder, and each annular segment is linearly displaceable along the linear guide by a respective manipulator. The processing unit permits a gap dimension between the processing cylinders of the processing unit to be adjustable in a simple, exact manner with precise repeatability. A label printing machine having the processing unit is also provided.

A machine for indirect ink-jet printing and more generally to a machine for indirect digital printing. A first transfer roller is at a printing position at which it provides ink to a first printing roller. The first printing roller engages and transfers ink onto a counter roller for the printing. When its printing has been completed, the first printing roller is moved to a storage position. A second printing roller is selectively moved from a waiting position to the working position to provide ink. The rollers are moved along guides between their positions.

The invention relates to a method for aligning at least two cylinders in a parallel manner relative to each other. In a first step, one cylinder is rotated and moved in a parallel manner towards the other cylinder in order to align a first end of the cylinder, and in a second step, the second end of the cylinder is rotated and moved towards the other cylinder in order to align the second end of the cylinder.

A flexible-electronic-device manufacturing apparatus for manufacturing an electronic device including a flexible base material and a plurality of functional layers provided thereon includes: an impression cylinder configured to hold and transport the base material; impression-cylinder driving means for rotating the impression cylinder; processing means for performing a plurality of processes for providing the plurality of functional layers by a printing method or a coating applying method on the base material held on the impression cylinder; impression-cylinder phase detecting means for detecting the phase of the impression cylinder; and controlling means for controlling the impression-cylinder driving means and the processing means based on the result of detection by the impression-cylinder phase detecting means.
