Abstract
The present invention concerns an abrasive band-type polisher having a plurality of contact wheels with differing profiles carried on arms which are rotatable to bring respective ones of said contoured contact wheels into engagement with the band to cause the band to assume the profile of the contact wheel. Special provision is made to allow polishing of workpieces without engagement thereof with the structural portions of the polisher, to facilitate accurate tracking of the band during polishing, and to facilitate the substitution of contact wheels.
