Abstract
An extrusion coating device has a die fitted with a paint sink fed with a paint, a slit extending from the paint sink to the distal end of the die, and a smoothing plate provided in the vicinity of the distal end of the die. The paint is extruded onto a continuously travelling support so as to be coated on the support. The smoothing plate is formed of a magnetic material and is magnetized to an opposite polarity to that of a magnet disposed via a gap of a pre-set length from the smoothing plate. The support is caused to travel along the end face of the smoothing plate so that the paint is coated on the support. The coating device enables a good coating film of a reduced film thickness to be produced while enabling high speed coating.
