PURPOSE: To link a feeder at inching operation time and to disuse the manual transfer of materials by providing the means to drive a feeder in the preset quantity corresponding to the current position of a slide on each vertical motion of the slide.

CONSTITUTION: The exciting pattern of exciting pattern table is readout in order on each stepping of a ring counter 24 by the pulse generated by oscillator 21 and given to a motor driving part 28. The motor driving part 28 drives the motor 17 for feeder driving according to the exciting pattern thereof and the materials are fed by the quantity corresponding to this exciting pattern. Due to the exciting pattern table 26 making the same address accessible simultaneously with a time table 25 the material is transferred simultaneously with the vertical motion of the slide completely.
