摘要

An object of the present invention is to provide a method and apparatus for applying a coating agent on both sides of a coating material for a printed wiring board or a sheet metal moving method, an apparatus, and a drying method and apparatus. The double-sided coating method for a printed wiring board or a sheet used for sheet metal processing is performed by removing a non-coated portion of a plate and simultaneously applying a coating agent on both sides of the plate, and conveying the plate by a conveyor or holding a portion of the non-coated portion by holding the non-coated portion. Each process of hanging and conveying a board | plate material is included.;The double-sided coating device includes an application means for simultaneously applying a coating agent on both sides of the plate, and the application means is applied using two application rolls provided with a width that is narrower than the width of the plate or more than the width of the plate so that the plate can be inserted and moved. The coating agent is applied by the control means for controlling the non-contact contact of the roll with the sheet material.
