摘要： Coating equipment 20 with an extrusion type coating head comprising a back edge 6 having a top side which slopes away from a support from the height of the top of a front edge 5, a coating fluid spouting slot 4 defined by both the edges, and guide plates for regulating the width of a coating fluid spouted from the slot tip on both side ends of the slot for applying the coating fluid to the support surface from the slot 4 in a non-pressurized condition. The nearest point to the support surface in the slot corresponding portion of the upper edge of the guide plate 7 is positioned slightly upstream from the center line of the width of the slot along the support running direction and the area given by the product of the distance between the nearest point and the support surface and the width of the slot is made a specific value or less. The coating equipment thus formed has no risk of damaging the support and effectively lessens the effect of air entering from both end sides of an application point of a coating fluid during a high speed thin coat application and produces no film cut when the coating fluid is applied to the running support surface by non-pressurization type coating equipment.
