Abstract
Disclosed is a control system for an ink blade of a printing machine provided with a series of key setting units each having a key position sensor and a key drive controlled by an adjusting device described in patent application Ser. No. 252,126. In order to achieve proper adjustment of marginal key setting units, there is provided a switching unit with a plurality of contacts assigned to respective key position measuring sensors and including additional switching contacts assigned to imaginary key position setting units adjoining the real setting units at each end of the ink zone. The additional marginal switching contacts are connected to the output of assigned sample-and-hold members which apply thereto the measured value from the extreme actual position sensors so that comparing differential transducer comparing the measured values of consecutive pairs of position sensors always produces a starting difference which does not exceed a predetermined limit value.
