Apparatus and method of material removal with fluid flow within a slot.

摘要

Apparatus and method for cleaning material at the outer edge (200) of an object (158) by applying a fluid, which can be a solvent, for the material to a flat surface (198) adjacent the edge (200) by contact and moving the solvent onto the edge (200) by centrifugal force. A slot (160) is provided in a planar surface (162). The slot (160) is arcuate and elongated. The fluid (193) is directed along the slot (160) in the direction of rotation by a baffle (182). The slot (160) has a botton (171) sloping upward toward the planar surface (162) in the direction of rotation. A notch is provided between an edge of the planar surface (162) and the slot (160) to act as a spillway for excess solvent.
