Head flat Dwell Flat The flat area of the head that receives the compression force from rollers in upper punches and determines the weight and ejection height in lower punches. Outside head Angle The area gets in touch with the roller prior to head flat, while compression. Inside Head Angle This is the area, which pulls down the lower punches after ejection and lifts the upper punches after compression.
