  • Patent number: 4032056
    Abstract: A roll feeder device for press works utilizing a barrel cam drive system having a sinusoidally grooved portion engageable with rollers secured to an indexing plate which transmits the rotational motion of the main drive shaft of the press to the feed rolls so as to coordinate feeding of material to movement of the press in such a manner that the material is fed with a substantially constant velocity during the material feed portion of the cycle. A braking system is provided in which the driven feed roll is moved away from the material being fed, in response to a camming action of a lever mechanism coordinated to the movement of the press through rotation of the main drive shaft.
