Abstract: A press for forming articles such as sphere-like objects and the like from workpieces includes a frame having two fixed mating dies mounted thereon and a crankshaft rotatably mounted on said frame, the crankshaft having crank arms actuating movable dies. A stationary shearing bushing means is disposed between the two fixed dies, and means are provided for feeding an elongated rod to the shearing bushing means. The shearing bushing means has an entry side and an exit side, and a movably mounted shearing knife means mounted on the entry side of the shearing bushing means is operable to cut blanks from the elongated rod. A feeding means is movably mounted on the exit side of the shearing bushing means and is operable to simultaneously receive a cut blank at the exit side of the shearing bushing means while delivering another cut blank to one of the fixed dies.

Abstract: There is disclosed a device for lapping an unlimited number of balls in continuous operation. The device has a stationary working disc and two rotary working discs which are driven in opposite direction and at differential speeds. The rotary discs and the stationary disc define therebetween a working gap into which balls to be lapped are continuously fed and from which they are discharged after having passed through all or part of the gap. Driving of the rotary discs in opposite direction and at differential speeds causes the balls to move along the gap and to be simultaneously lapped. The rotational speeds of the rotary discs can be independently adjusted, thereby controlling the dwell time of balls in the gap.

Abstract: A reciprocating press for shaping or forming a workpiece such as a sphere or the like includes two oppositely reciprocally movable dies mating with two fixed dies. A feed mechanism reciprocal in a lateral direction is operable to shear off workpieces from an elongated rod and to feed the sheared off workpieces to the fixed dies as the movable dies move in opposite directions.
