PURPOSE: To transport objects to be coated while wiping away a coating material, etc., sticking to their rear surfaces before drying to the touch by flying the objects to be coated through a curtain of the coating material, etc., to land on a belt conveyor consisting of a perforated material moving in a backward direction and wiping away the coating material, etc., while slipping the objects by inertia force.
CONSTITUTION: Sheet metals 3 transported by the conveyor of a front part fly to punch through a fluid film 6 of, for example, a liquid gasket, in a coating section 2 of a curtain flow system and land on the conveyor 1 for wiping away of the rear part. The sheet metals are then transported to the next roller conveyor 7 while sliding thereon and are transferred to a drying stage. The belt conveyor 1 for wiping away is formed by using paper as a belt base and is installed with a paper roll 8 and a take-up roll 9 under the conveyor 1. This take-up roll 9 is so constituted as to automatically perform the operation of standing still for, for example, 3 seconds, then taking up the paper of the prescribed length as one cycle. Consequently, the sheet metals 3 are transported while the coating films on the rear surfaces thereof are wiped away by the paper belt before drying of the coating film to the touch.
