DEFINITION

Classification: 83/404

(under subclass 401) Device provided with a plurality of separated cutting zones, at each of which zones is located a cutter cutting in a plane acting on a distinct portion of the same material, and including means to effect movement of said material from a preceding cutting zone to a succeeding cutting zone in sequence.

(0.5) Note. In this subclass, a plurality of punches or dies which act simultaneously in a single stroke or cycle of the tool actuator will be considered as a single cutting zone or tool station: hence, means to feed to such zone will be found elsewhere in this group of subclasses (401+). If two punches or sets of punches are positioned at the same general location, but do not act simultaneously, then the two punches will be considered to define plural cutting zones and the device will be found here (404).

(1) Note. The word "material" as used above is inclusive of that work which is to be cut at a first cutting zone, and of that product of the first cutting zone which is work to be cut at a second cutting zone.

(2) Note. For further amplification of specific forms of "cutting zone", see (1) Note of subclass 405, (1) Note of subclass 406, and (2) Note of subclass 407.

(3) Note. This and indented subclasses differ from

subclasses 78+ in that these subclasses (404+) provide for machines distinguished by a second cutter which acts upon the product of a first cutter and, further, by structure for moving the material (i.e., the product of the first cutter) between the sequentially acting cutters; whereas subclasses 78+ provides for machines having means for removal of the final product.

(4) Note. Included in this and indented subclasses are patents disclosing means for changing the direction of the material movement, or the path of the material, between the sequentially acting cutters or cutting zones. SEE OR SEARCH THIS CLASS, SUBCLASS:

78+, for delivery means for the product of a cutter and see (1) Note above.

213+, and 255+, for plural tool stations of the type provided for in subclass 202.

300, and 301+, for a "flying" cutter and another type cutter operating sequentially.

357, for plural tool stations, in a device wherein a tool is synchronized with moving work.

513+, for plural, individually actuated tools.
