Abstract:
A machine having a work piece loading station, a work piece machining station, and a work piece unloading station, said machine comprising:a first jaw;a second jaw connected for movement between a first position and a clamping position with respect to said first jaw;first spring means for biasing said second jaw toward said first position;said jaws being adapted to slidably receive a work piece therebetween when said second jaw is in said first position;means for cyclically carrying said jaws from the loading station to the machining station and then to the unloading station and then back to the loading station;a cutting tool positioned for machining engagement with a work piece carried in said jaws when in said machining station;means for clamping said work piece between said jaws in said clamping position to prevent movement of said work piece with respect to said jaws when in said machining station;said clamping means including (i) rolling means positioned to engage said second jaw as it is carried into said machining station, and (ii) second spring means connected to said rolling means for biasing said second jaw toward said first jaw and clamping the work piece between said jaws; andmeans for automatically disengaging said rolling means from said second jaw when said jaws are carried from said machining station.
