ABSTRACT:
Apparatus and method for applying a coating, such as a lubricant, on at least a portion of the outer peripheral surface of a can body wherein a turret having a plurality of pockets formed in its outer peripheral surface is mounted for rotation about a relatively fixed axis and during the rotation thereof a can body is fed into each pocket. The can body in each pocket is held against the outer peripheral surfaces of a pair of rotating rolls having a space therebetween by a vacuum acting through the space so that the can body is rotated thereby and while rotating is moved against a heated arcuate wick located in a heated arcuate support and having a supply of lubricant therein so as to form a coating of lubricant on the at least a portion of the outer peripheral surface. The peripheral velocity of the outer peripheral surface of the rotating can body about its own axis is the same as its peripheral velocity imparted thereto by the rotation of the turret about its own axis and is rotating in a direction opposite to the direction of rotation of the turret so that there is substantially no relative sliding movement between the at least a portion of the outer peripheral surface and the arcuate wick as the coating of lubricant is applied.
