ABSTRACT:
A method and apparatus for a drive system having an intermittently rotating output shaft. In operation, the output shaft is caused to accelerate to a constant rotational velocity, held at that velocity for a predetermined portion of its rotation, then decelerated to zero velocity. The acceleration and deceleration values are caused to be low in magnitude so that components of the system are subjected to reduced shock loadings and generate reduced noise as compared to a rapid acceleration and deceleration system. Particular applicability for the system is found in document endorsers having an endorsing plate connected to the output shaft and rotated such that the endorsing plate contacts and imprints documents in an endorsing area on command.
