Description: |
| Abstract:
A drive mechanism for a press feed device which operates in synchronism with the cycling of the press but which avoids shock loads on the feed rolls at the start of each feed cycle. This is accomplished by modifying the simple harmonic drive motion derived from the rotary member of the press with a harmonic motion of a different frequency so as to produce a resultant motion having zero acceleration at the beginning and middle of each cycle. |
