Abstract

In order to provide a coating apparatus in which an edge can be fixed rigidly so as to apply a coating agent at a uniform thickness, edge units are provided which comprise edge support members (13a, 14a, 15a) and edges (20, 21, 22) which are attached to the tips of the edge support members so as to slide on a flexible tape support member (23). The edge (21) which is not disposed at both ends in the running direction of the flexible tape support member is fixed to the edge support member (14a) by an edge fixing member (24) which is inserted in a direction from a bottom portion of the coating apparatus toward the edge (21). The edge (21) is fixed so as to be pulled into a recessed section (30) formed on the edge support member (14a) by the edge fixing member (24).

Description

technical field [0001] The present invention relates to a coating device for applying a thin layer of coating agent to a running flexible belt support. In particular, the invention relates to applicator heads for discharging coating agent. Background technique [0002] As for a coating head for forming a thin coating layer, generally known is, for example, a structure disclosed in Japanese Unexamined Patent Application, First Publication No. Sho62-241574 (hereinafter referred to as first prior art). Such as Figure 5 As shown, the applicator head 5 has two parallel parts 1 , 2 . Between the two parallel pieces 1 , 2 a groove 3 is formed. Adjusting pieces 4 , 4 are arranged at both longitudinal ends of the slot 3 , which are used to adjust the width of the slot 3 . [0003] In the coating head 5 having this structure, when the long wide flexible belt support 6 runs on the top end of the parallel edge member in the direction shown by the arrow A in the figure, it is dischar...
