An arrangement for a corrugator for producing corrugated cardboard comprises a material web delivery device for delivering a material web and an edge cutting device, which is arranged downstream of the material web delivery device in a transport direction of the material web and has at least one edge cutting apparatus for edge-cutting the material web, and a digital printing device, which is arranged downstream of the edge cutting device in the transport direction of the material web for printing on the material web.

Systems and methods for laser assisted deposition of a material includes a printing unit configured to print individual dot-like portions of a material from a donor substrate onto a receiving substrate, and a vacuum shuttle configured to be positionable in two or three dimensions between the printing unit and the donor substrate and to engage the donor substrate upon application of a vacuum to the vacuum shuttle. The printing unit may include a coating system and a laser. The vacuum shuttle includes a vacuum channel about its periphery and an open window through which the laser irradiates the donor substrate. The vacuum channel is fluidly coupled to a vacuum inlet for receiving a vacuum suction, thereby to engage the donor substrate and hold it taught against the bottom of the vacuum shuttle in operation. The vacuum shuttle may also include one or more distance measuring sensors and fiducial markers.

The present invention discloses a silicon wafer printer for double half-cell printing, comprising a work platform, a turntable assembly, a front-end conveyor, a left calibration module, and a right calibration module. A calibration vision camera is mounted above the front-end conveyor's end. The left linear module connects to a left motor module and then a left suction module. The right linear module connects to a right motor module, two calibration cylinders, calibration bearings, and a right suction module. It uses visual positioning to determine double half-cells' position/angle, adjusts the right half-cell with the left as reference, shortens alignment time, adopts single-head front-to-back printing and a smaller indexing disc, boosting turntable printing efficiency.
