Abstract:
1. A dual-purpose surface-treating blade assembly comprising: (a) an elongate blade holder for holding and loading a surface-treating blade member against a moving surface being treated; (b) a one-piece elongate blade member having (i) a first end, (ii) a second end, (iii) a first elongate edge connecting said first end and said second end for mounting to said elongate blade holder, (iv) a second elongate edge opposite said first elongate edge for contacting and treating said surface being treated, and (v) first and second sides each connecting said first elongate edge to said second elongate edge, said one-piece elongate blade member comprising a mid-portion for applying a first edge-loading force to lightly contact and remove random spots from a corresponding mid-portion of said moving surface being treated, a first end portion, and a second end portion, located towards said first end and said second end respectively, for applying a second different edge-loading force and a third different edge-loading force respectively for strongly contacting and fully cleaning corresponding edge portions of said moving surface being treated; and (c) a first shim device and a second shim device assembled respectively to said first end portion and said second end portion of said one-piece elongate blade member for increasing a magnitude of each of said second different edge-loading force and said third different edge-loading force relative to said first edge-loading force.
