Control system for blank presser
摘要:
A control system for a blank presser used to touch down blanks fed from a conveyor controls the blank presser so as to hold down each of the blanks at the proper time, so as to thereby prevent them from scattering or jamming up. The control system can control the blank presser automatically even if the speed or length of the blanks changes.
