Abstract: A sleeve-type gas spring for a turret indexing press has an annular piston operably associated with a punch tool to reciprocate therewith and defining in part an annular gas chamber constructed to receive a gas under pressure. As the punch tool and piston are driven to their extended position by a press ram or some such other power device, the volume of the gas chamber decreases thereby increasing the pressure within the gas chamber such that when the ram is retracted, the pressure of the gas acting on the piston displaces the piston and the punch tool to their retracted positions. The force acting to retract the piston and the punch is dependent on the initial pressure of the gas within the gas chamber and the change in volume of the gas chamber as the punch tool and piston are extended.

Abstract: In a method and apparatus for rotating loose laminations in a loose lamination die, a strip is fed through the die to a rotatable blanking chamber of a blanking station. There, a punch engages with a die ring to punch a lamination free from the strip. The rotatable blanking chamber is biased in an upwardly direction. When the punch is not engaging with the die ring, the rotatable chamber is in an upward position wherein a gap develops between laminations retained at a bottom of the rotatable chamber, and those laminations lying directly below the rotatable chamber. The rotatable chamber can then be rotated without damage to the laminations at the gap because of the presence of the gap. Thereafter, a succeeding lamination can be punched after the rotation has occurred. As the punch engages the strip on top of the die ring, the rotatable chamber is pushed downwardly so that the gap at the bottom of the rotatable chamber disappears.
