Abstract

본 발명은 가소성 지지체상에 도포액을 도포하기 위한 도포장치(10)에 관한 것으로, 가소성 지지체의 주행방향의 순으로 백에지(b)와 프론트에지(a)로 된 선단부의 두에지 사이에 형성된 일정간격의 슬릿(12)을 통해 연속적으로 압출되는 도포액이 소정의 주행경로를 따라 주행하는 가소성 지지체의 표면에 밀착되어 도포되도록 구성된 도포장치가 있어서, 상기 선단부의 각 에지는 평탄면의 조합이나 돌출된 둥근 모양의 형상을 가지며 프론트에지의 백에지측 최정점을 통과하는 수직선과 프론트에지측의 슬릿 벽면의 연장선간의 최단 거리(L1)가 슬릿간격(d)의 0.5~2배이고, 프론트에지의 두께(W1)의 0.5배 이하이며, 백에지의 최정점을 지나는 수평선과 프론트에지의 최정점을 지나는 수평선간의 거리(H)가 슬릿간격(d)의0.5∼2배이고, 백에지의 최정점을 지나는 수직선과 백에지측 슬릿의 연장선간 최단거리(L2)가 슬릿간격(d)의 0.2~1.5배의 범위내인 것을 특징으로 하며, 이러한 특징의 본 발명에 의하면 횡방향의 단, 길이 방향의 줄무늬, 스크래치, 핀홀, 오버 플로 등의 도포 결함이 없는 양호한 도포면을 얻을 수 있으며 목표로 하는 최종 제품의 특성도 매우 우수한 결과를 얻을 수 있게 된다.The present invention relates to a coating device (10) for applying a coating liquid on a plastic support, which is formed between the two edges of the front end (b) and the front edge (a) in the order of running direction of the plastic support There is a coating apparatus configured to apply the coating liquid continuously extruded through the slit 12 at a predetermined interval in close contact with the surface of the plastic support that travels along a predetermined running path. It has a protruding round shape and the shortest distance (L 1 ) between the vertical line passing through the front edge of the front edge and the extension line of the slit wall on the front edge is 0.5 to 2 times the slit spacing d. the thickness (W 1) 0.5 times or less, 0.5 to 2 times the distance (H) between the horizontal line passing through the choejeongjeom the horizontal and the front edge of the bag passing through the choejeongjeom edge slit spacing (d) of the back edge of choejeongjeom I vertical line and the back edge side of the shortest distance between the extension line of the slit (L 2) has a slit distance (d) 0.2 ~ 1.5 times, and characterized in that within the scope of, the present invention in these characteristics only in the lateral direction, longitudinal direction It is possible to obtain a good coated surface free from coating defects such as streaks, scratches, pinholes, and overflows, and to achieve very good characteristics of the target end product.
