ABSTRACT:
In coating a liquid coating composition on a spliced web comprising contiguous web portions spliced together with a splicing tape, for example in the coating of gelatin emulsions or other hydrophilic colloid compositions on butt-spliced photographic support materials, coating disturbances caused by the splice are reduced by the use of a thin tape overlying the trailing edge of the splicing tape. The thin tape serves as a ramp between the splicing tape and the surface of the web and introduces only a very small vertical drop at its own trailing edge, to thereby permit coating of the spliced web with minimal disturbance of the coating operation.
