ABSTRACT:
Intensity of vibrations emitted by tool and workpiece acted upon is reduced by an enveloping mat of floppy fibres. In a heel attacher, for instance, the mat reduces by 14 or more decibels, and an operator incurs no risk of injury to his hands should they be in the path of the mat when it is moved to or from a heel and shoe being attached.
