摘要:
Die Erfindung betrifft ein Verfahren zum Bedrucken von Plattenmaterial (2) mit einem Druckbild, bei welchem das Plattenmaterial (2) von einer Zufuhrstation (5) in eine Druckstation (3) bewegt wird, in dieser das Druckbild aufgebracht und aus dieser mittels einer Transportvorrichtung (18) in Transportrichtung (4) weiterbewegt wird. Dabei wird das zu bedruckende Plattenmaterial (2) in Transportrichtung (4) zumindest in einem Einlaufbereich (32) in die Druckstation (3) unmittelbar hintereinander zu einer Reihe (36-38) angeordnet und während dem Druckvorgang gemeinsam durch die Druckstation (3) hindurchbewegt, wobei das Druckbild mittels einer Tintenstrahl-Druckvorrichtung (13) aufgebracht wird.
摘要:
Provided is a thermal activation device including a thermal activation head (11) for thermally activating a heat-sensitive adhesive layer of a sheet material (3), a platen roller (12) for holding and conveying the sheet material (3), the platen roller (12) being brought into press contact with the thermal activation head (11), and a pair of conveyor rollers (14a and 14b) that convey the sheet material (3), the conveyor rollers (14a and 14b) being provided to be located on an upstream side of the thermal activation head (11) in a conveying direction of the sheet material (3). Holding force for the sheet material (3) by the pair of conveyor rollers (14a and 14b) is made larger than holding force for the sheet material (3) by the platen roller (12) and the thermal activation head (11).
摘要:
A roller assembly (10) is provided with openings (18) in its outer surface for selective communication with a source of vacuum or a positive pressure. The openings (18) may be angled along the roller rotational axis (52) to impart a component of velocity to the paper (60) perpendicular to the tangential roller surface velocity. Additionally, by selectively connecting the openings with sources of pressure and vacuum, enhanced paper alignment is achieved, multiple paper feeds eliminated, transitions between different velocities of rollers completed, or paper reverted so that printing can be achieved on first and second sides thereof.
