ABSTRACT:
A feeder is acted upon by opposing hydraulic drives and a spindle drive limits the advance. Hydraulic buffers are interposed either between the spindles and the feeder or between a carriage carrying the spindle drive and the machine bed. The buffer biasing force exceeds the force exerted by the feeder advance upon the feeder. The rate of buffer response is tracked separately.
