Abstract
Apparatus for stripping a cylindrical workpiece, such as a can body, from a cylindrical supporting device, such as a punch of a can body making machine, using a plurality of pivotally mounted fingers which are mounted between a non-stripping location so that the cylindrical workpiece and the cylindrical supporting device may pass through the stripping fingers without contacting the stripping fingers and a stripping location whereat the stripping fingers will contact the leading edge of the cylindrical workpiece to disengage it from the punch and wherein the stripping fingers are formed from a magnetically conductive material and are moved into the stripping location by electromagnetic apparatus.

Apparatus for stripping a cylindrical workpiece from a reciprocating cylindrical supporting device having a forward and a return stroke and on which the cylindrical workpiece is supported so as to have a leading end surface during the return stroke comprising:
- housing means for supporting the apparatus circumjacent the cylindrical workpiece and the cylindrical supporting device;
- a plurality of circumferentially spaced apart stripping fingers pivotally mounted in said housing means;
- pivot means for mounting said stripping fingers for pivotal movement around axes extending transverse to the direction of movement of said cylindrical workpiece and said cylindrical supporting device for pivotal movement between a non-stripping location whereat said cylindrical workpiece and said cylindrical supporting device may pass through said stripping fingers without contacting said stripping fingers and a stripping location whereat said stripping fingers will contact said leading end of the cylindrical workpiece to strip said cylindrical workpiece from said cylindrical supporting device;
- resilient means for moving said stripping fingers into said stripping position;
- and
- force applying means mounted in said housing means to apply a force to each of said stripping fingers to move said stripping fingers into said non-stripping location.
