Film applicators, as a gate roll train or an inclined two-roll unit equipped with applicator heads, are used to prepare the surfaces of paper and board grades for coating or finishing operations that follow. Film coater technology dates back to the early 1930’s where several process and quality challenges slowly became insurmountable.
