ABSTRACT:
A coater applies ultraviolet curable coating material to the opposite sides of roll film by a double-sided coater which employs offset coating rolls and smoothing bars. A splice detector responds to the occurrence of a splice upstream of the coater and causes the splice region to move through the coater without applying coating material to the splice region, by lifting the emulsion side of the film off of the coating roll as the splice passes and by interrupting the operation of the smoothing bars and the offset applicator roller on the non-emulsion or base side, concurrently with the passage of the splice therepast.
