Abstract
An improved flywheel for an electro-mechanical tool, such as a nailer or stapler. The tool is of the type provided with a driver which is frictionally moved through a working stroke by means of an electrically driven flywheel which presses the driver against a support element, such as a counterrotating flywheel, a low inertia roller, or the like. The flywheel is provided with circumferential grooves while maintaining the optimum contact area between the flywheel and the driver. The grooves provide voids along the travelling driver-flywheel contact line into which foreign material on the driver and flywheel flows to prevent build-up of such foreign material at the driver-flywheel contact area sufficient to result in loss of friction therebetween.
