Abstract

This rotary stripper is provided with a cylindrical housing rotatable in one direction. The housing has a plurality of peripheral wall openings through which project arms of flexible blades. Each blade has a longer work engaging flexing arm, and a shorter reaction arm which intercepts a longer flexing arm as it rebounds forwardly from the work. Both arms may project through the same wall opening to confront each other. Alternatively the longer arm may project through one wall opening while the reaction arm projects through the next trailing wall opening to confront the longer arm of the next trailing blade. Each wall opening has a curved abutment surface at the trailing side of each longer arm in the opening. This surface is contacted by the longer arm as it ends rearwardly during contact with the work. The abutment surfaces and the reaction arms are contoured to limit the range of stresses set up in the longer arms as they flex and rebound, to a range which will avoid producing fatigue failure in the longer arms, thus lenthening their useful lives.
