A roll coating system for coating strip metal having a plurality of coating head rolls mounted on support sleds capable of linear translation along a single rail. Precision linear actuators are located between each support sled and between one of the sleds and a fourth sled. A splice traverse mechanism actuated by a piston/cylinder displaces the fourth sled. Each of the rolls can be independently displaced or the entire head can be displaced by the splice traverse mechanism. Force measurement sensors are located in the support sleds for an accurate measurement of nip pressures between the respective rolls. The elastic response of the support sleds may be varied to alter the natural resonant frequency of the coating system. The movement of a pan lift mechanism is coupled to the movement of the pickup roll so as to eliminate the chance for collision therebetween. The movement of a lift roll in a double coating environment, or the movement of a pass line roll in a U-wrap environment may be coupled with the movement of the roll coating head.
