  • Patent number: 4593616
    Abstract: A dabber printing machine for printing of workpieces with printing ink wherein a dabber-holder is fastened from below to a first and second vertical carriage (6, 6'). The dabber-holders run parallel to one another. In each case, in one extreme position of the horizontal carriage (7), with which both vertical carriages (6, 6') are connected, the vertical carriages (6, 6') are pressed downward by two levers (14) of a pair of gear units (12). In the other extreme position, such are pressed downward by the levers (14) of the other pair of gear units (12). Thus, the dabber-holders with the dabbers jointly and simultaneously make vertical and horizontal movements in the form of an inverted U. A step of operation of the transfer element from printing station to printing station optically occurs upon every or every other horizontal movement. Thus, indexing of the workpieces to be printed is simplified and the efficiency of the printing machine is doubled.
