Abstract
An apparatus for applying pressure to at least a portion of an edge surface of a workpiece comprises a frame, a first roller, a second roller, a rotation-control member, a first biasing member, and a second biasing member. The first roller and the second roller are coupled to and are rotatable relative to the frame while at least one of the first roller or the second roller is translatable relative to the frame. The rotation-control member is coupled to and is movable relative to the frame, controlling rotation of the first roller and the second roller. The first biasing member is coupled to the first roller and to the second roller and configured to operate in tension. The second biasing member is positioned, in compression, between the frame and the rotation-control member.
