An apparatus for applying pressure to at least a portion of an edge surface, which bridges opposing faces 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 the frame and are rotatable relative to the frame. At least one of the first roller or the second roller is translatable relative to the frame along a first axis. The rotation-control member is movable relative to the frame, controlling rotation of the first roller and the second roller relative to the frame. The first biasing member is configured to operate in compression along a second axis. The second biasing member is positioned, in compression, between the frame and the rotation-control member.
