The invention further relates to a method for coating the peripheral edge of a workpiece with the aid of a coating head. ## Claims ### Claim 1 A method of coating a peripheral edge of a workpiece using a coating apparatus having a coating head, comprising applying a coating agent to the peripheral edge via a coating-application means provided on/in the coating head; wherein at least one portion of the peripheral edge passes the coating head at least twice; wherein, during a first passage operation, a coating agent is applied to the workpiece and excess coating agent is removed by means of an air stream; wherein the coating head has a means for generating the air stream, and wherein the means is a negative pressure; wherein, during a second passage operation, the coating agent is removed and/or distributed and the coating agent is not applied to the workpiece; wherein the coating apparatus has a movement means which is configured such that the workpiece and the coating head are moved relative to one another; wherein movement takes place in at least two directions in space; and wherein the coating-application means and the means for generating the air stream can be operated separately from one another. ### Claim 2 (depends on 1) The method as claimed in claim 1, wherein process conditions which prevail in the coating head during the first passage operation are different from those which prevail during the second passage operation. ### Claim 3 (depends on 1) The method as claimed in claim 1, wherein relative movement between the workpiece and coating head during the first passage operation differs from that during the second passage operation. ### Claim 4 (depends on 1) The method as claimed in claim 1, wherein the movement means moves the workpiece and/or the coating head in at least two directions in space which are provided at an angle in relation to one another. ### Claim 5 (depends on 1) The method as claimed in claim 1, wherein the movement means rotates the workpiece. ### Claim 6 (depends on 1) The method as claimed in claim 1, wherein the movement means orients the workpiece prior to the latter being treated. ### Claim 7 (depends on 2) The method as claimed in claim 2, wherein relative movement between the workpiece and coating head during the first passage operation differs from that during the second passage operation. ### Claim 8 (depends on 2) The method as claimed in claim 2, wherein the movement means moves the workpiece and/or the coating head in at least two directions in space which are provided at an angle in relation to one another. ### Claim 9 (depends on 3) The method as claimed in claim 3, wherein the movement means moves the workpiece and/or the coating head in at least two directions in space which are provided at an angle in relation to one another. ### Claim 10 (depends on 2) The method as claimed in claim 2, wherein the movement means rotates the workpiece. ### Claim 11 (depends on 3) The method as claimed in claim 3, wherein the movement means rotates the workpiece. ### Claim 12 (depends on 4) The method as claimed in claim 4, wherein the movement means rotates the workpiece. ### Claim 13 (depends on 2) The method as claimed in claim 2, wherein the movement means orients the workpiece prior to the latter being treated. ### Claim 14 (depends on 3) The method as claimed in claim 3, wherein the movement means orients the workpiece prior to the latter being treated. ### Claim 15 (depends on 4) The method as claimed in claim 4, wherein the movement means orients the workpiece prior to the latter being treated. ### Claim 16 (depends on 5) The method as claimed in claim 5, wherein the movement means orients the workpiece prior to the latter being treated. ### Claim 17 (depends on 12) The method as claimed in claim 12, wherein the movement means orients the workpiece prior to the latter being treated. ### Claim 18 (depends on 1) The method as claimed in claim 1, wherein the apparatus fully coats the peripheral edge of the workpiece.
