Abstract

According to Fig. 1, electrode print head 1 is guided during its movement in line direction (arrow direction F forward; arrow direction B backward) by two guide rods 2 and 3 (it can, for example, be moved by a continuous cable line (not shown).) The print head is pivotable around guide rod 2 in double-arrow direction R. During the printing process, its electrodes rest on the metal paper (not shown) due to the specific gravity of the print head in combination with its leverage. For setting a specific pressure of the electrodes, a mass (not shown) shiftable on the print head is used. In order to make sure that at the beginning and the end of the line the print head can be lifted from, or lowered onto, the metal paper impact-free, guide rod 3 is provided eccentrically, in accordance with Fig. 2.

Pivotable Electrode Print Head for Metal Paper Printers

According to Fig. 1, electrode print head 1 is guided during its movement in line direction (arrow direction F forward; arrow direction B backward) by two guide rods 2 and 3 (it can, for example, be moved by a continuous cable line (not shown).) The print head is pivotable around guide rod 2 in double-arrow direction
R. During the printing process, its electrodes rest on the metal paper (not shown) due to the specific gravity of the print head in combination with its leverage. For setting a specific pressure of the electrodes, a mass (not shown) shiftable on the print head is used. In order to make sure that at the beginning and the end of the line the print head can be lifted from, or lowered onto, the metal paper impact-free, guide rod 3 is provided eccentrically, in accordance with Fig. 2. Its rotation by 180OE around axis A effects a lifting of the head (e > h); a further rotation by 180OE causes a lowering of the head. Dimension h serves for the head adjustment. In the position of guide rod 3 according to Fig. 2, the electrodes are placed on the metal paper. By removing upper part 4 of the guide rod, the print head in the area of guide rod 3 maintains, during printing, free tolerance relative thereto in order to compensate for irregularities. Lifting and lowering of guide rod 3, provided it is supported cylindrically and axis- symmetrically, can also be effected by a cam control (not shown) in support 5...
