Embodiment Construction

[0027] Embodiments of the coating apparatus of the present invention are described below with reference to the drawings. Although the present invention relates to a coating apparatus for uniformly coating the surface of flexible belt supports such as films and sheets running in one direction with a coating agent to form a thin coating, the specific structural and operational details disclosed herein are representative only. nature and do not limit the scope of the present invention.

[0028] An embodiment of the coating device of the present invention is in figure 1 shown in . exist figure 1 , the coating device has a coating head 10 . In the coating head 10 , the first groove 11 is located between the first edge unit 13 and the second edge unit 14 , and the second groove 12 is located between the second edge unit 14 and the third edge unit 15 . The first, second and third edge units 13, 14 and 15 are arranged in this order in the running direction of the flexible belt s...

Abstract

In order to provide a coating device in which the edges are rigidly fixed so that the coating agent is applied with a uniform thickness, an edge unit is provided comprising edge supports (13a, 14a, 15a) and edges (20, 21, 22), said edge is connected to the top end of the edge support to slide on the flexible belt support (23). The edges (21) which are not arranged at both ends in the running direction of the flexible belt support are fixed to the edge support (14a) by means of edge fixings (24) extending from the bottom of the coating device to the Insert in the direction of the edge (21). Said edge (21) is fixed so that it is drawn into a groove (30) formed on the second edge support (14a) by the edge holder (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...
