<p>According to the invention, there is provided a silk or metal screen coating apparatus including a pair of squeegee buckets between which a screen frame is inserted. The screen frame extends vertically between the squeegee buckets and defines an opening surrounded by the periphery thereof. A silk or metal screen is stretched in the opening and held by the periphery of the screen frame. The squeegee buckets extend horizontally to be opposed to each other on the opposite sides of the screen frame. A sensitizing or reinforcing agent is received in the squeegee buckets. The squeegee buckets are moved upwardly along the screen for coating the sensitizing or reinforcing agent onto the both faces of the screen. The apparatus comprises a pair of one end carriages disposed in positions corresponding to one ends of the squeegee buckets and spaced from each other in the opposed direction of the squeegee buckets. The squeegee buckets are carried at one ends by the one end carriages separately from each other. The apparatus further comprises a pair of one end pillars extending vertically. The one end pillars are disposed in positions corresponding to one ends of the squeegee buckets and spaced from each other in the opposed direction of the squeegee buckets. The one end carriages are engaged with the one end pillars separately from each other to be moved upwardly along the one end pillars so that the squeegee buckets are moved upwardly along the screen. Accordingly, in the apparatus, the screen frame can be passed between the one end pillars and between the one end carriages to be inserted between the squeegee buckets. <IMAGE></p> |
