ABSTRACT:
The profile measurement control comprises a potentiometer adjustable by means of a lever. The voltage tapped-off the potentiometer is attenuated via a resistance network proportional to the radius of the base circle disc and additionally via an encoding switch and a voltage attenuating circuit when a certain pre-selected diagram length transmission or translation is exceeded. Thus a voltage is always supplied to the drive motor driving a generating carriage or slide which ensures for an optimum paper feed rate when the lever is located to engage a stop. Hence, the lever can be always adjusted to engage the stop without the preselected diagram length translation or the radius of the selected base circle disc having to be taken into account. Consequently, the measuring rate during series testing of gear profiles can be considerably increased.
