Abstract

807,805. Coating webs. ILFORD Ltd. April 23, 1957 [June 15, 1956], No. 18619/56. Class 140. Apparatus for applying a liquid coating to a moving support comprises a roller 4 round which the support 3 is caused to pass, a trough 2 for coating liquid so placed in relation to said roller that the support, as it passes round said roller makes surface contact with the liquid in said trough and therefore picks up liquid from said trough, an air blade 5 located at a distance following the coating point which applies a jet of air at substantially right angles to the support which is moving substantially vertically, and means for diverting away from the support the excess liquid removed by the air blade. The diverting means may be a wheel 6 (Fig. 1) rotating in the opposite direction to the main roller 4 or a scoop (Fig. 2) consisting of an arcuate plate 8 and an auxiliary trough 9 having therein means (not shown) for returning liquid to the trough. The liquid may be diverted to a separate trough and its viscosity and temperature adjusted before return to the main trough. The air blade may act on the support at a distance above the main roller in which case an additional support roller is supplied opposite the air blade. The apparatus may be used for coating film base with photographic gelatino-silver halide emulsion.
