Abstract
The coating material is supplied to a coating die provided with a manifold chamber, a draw-in chamber provided with a diaphragm, a supply passage and a discharge opening. The coating material is stored temporarily in the manifold chamber, is supplied through the supply passage to the discharge opening, and is discharged through the discharge opening onto the surface of the base sheet. The discharge of the coating material through the discharge opening is interrupted by deforming the diaphragm so as to form a draw-in chamber. The ball nut is driven by the servomotor so as to move the ball screw axially away from the supply passage to deform the flexible diaphragm so that the coating material is drawn into the draw-in chamber to interrupt discharging the coating material through the discharge opening. Thus, the coating material is applied intermittently to the substrate.
