DEFINITION

Classification: 72/292

BY TIGHTENING FLEXIBLE BAND OR CHAIN ABOUT WORK:

(under the class definition) Subject matter comprising means, or a method of using means, which includes a cable, a strap, or series of articulated links which engages and surrounds the major portion of the so-engaged periphery of work and, when placed under tension, applies deforming force to the work.

(1) Note. For placement in this subclass, the band or chain must encircle more than half the periphery of the workpiece (the remainder may be engaged by a fixed die or support); if the flexible tool means engages less than half the periphery of the work, it is regarded as a "yieldable-face" tool, for subclasses 396+, such tools requiring an opposed face

coacting tool to effect compression or crushing of work.
