DEFINITION

Classification: 72/396

Yieldable face portion or auxiliary tool on tool couple element:

(under subclass 394) Device wherein said movable work-engaging face portions are constituted by relatively distortable or displaceable parts of the work-engaging surface portion of one of said tools, or by a distinct relatively displaceable work-engaging member carrier by or associated with one of said tools, such that during an operation of the class type said relatively distortable or displaceable part or member, while in engagement with work, is distorted or bodily displaced with respect to its associated tool.

(1) Note. A device of this subclass typically comprises an opposed-face tool couple wherein one or both of the tools carriers a resilient mounted auxiliary tool, or has a differentially yieldable (e.g., elastic) face portion, thus modifying the effect obtainable with a simple tool couple.
