Patent number: 8312834Abstract: A coating apparatus includes a coating transfer roll that transfers a coating material from a coating material reservoir to a work piece. The coating material reservoir is formed between the coating transfer roll, a flexible blade and reservoir wall members. The flexible blade includes a first section that is fixed to a support. A second section of the flexible blade extends along a length of the coating transfer roll and is rotatable about the first section. An actuator selectively applies a pressure on the flexible blade during a coating operation to deflect the flexible blade and control a thickness of the coating material applied to the work piece.Type: GrantFiled: April 14, 2005Date of Patent: November 20, 2012Assignee: Hamilton Sundstrand CorporationInventors: Gordon W.
