The apparatus has a feed apparatus (10) and an evening-out apparatus (100) placed underneath the feed apparatus. The feed apparatus (10) has a feed chamber (12) with an inlet opening (13a), an outlet opening (13b), and a nozzle plate (18) with holes (19) and communicating with the outlet opening (13b) of the feed chamber. The evening-out apparatus (100) has at least one inclined surface (110) which forms a downwards sloping flow path (L1) for the treating agent. Jets discharge from the feed chamber (12) outlet opening (13b) through the nozzle plate (18) holes (19) to form a first treating agent flow (F1). One inclined surface (110) of the evening-out apparatus (100) receives the first treating agent flow (F1) and a second treating agent flow (F2) formed into an even laminar treating agent flow on the flow path (L1) of the evening-out apparatus (100) is passed onto a moving surface (200).
