DEFINITION

Classification: 83/192

(under subclass 188) Means wherein a plurality of tools is disposed around the outer periphery of the tubular work and each moves, in coaction with one or more internally disposed tools, to effect a cut.

(1) Note. The external tools may be supported on a common carrier, as in a conventional multiple punch ram means; or on separate carriers, including structurally independent actuating means, and may each contribute to a single combined cut line or function to effect separated cuts on the common work piece.
