ABSTRACT:
An apparatus for coating a liquid on opposite sides of a flexible material, which is particularly suitable for use in applying a splicing cement to predetermined surface areas on obverse and reverse sides of a vehicle tire tread. The apparatus comprises in combination: first sheet conveying means for transferring a flexible sheet material through a first coating position; first liquid coating means located at the first sheet coating position for applying a coating liquid on a predetermined surface on an obverse side of the sheet material; second sheet conveying means for transferring the flexible sheet material through a second liquid coating position; second liquid coating means located at the second coating position for applying the coating liquid on predetermined surface on a reverse side of the sheet material; and turn-over means located between the first and second sheet conveying means for transferring the flexible sheet material upside-down from the first to the second sheet conveying means. The first and second coating means each has a coating liquid reservoir which has a transverse slit in the bottom wall for allowing the coating liquid to drop by gravity forming a liquid film across passage of the transferred sheet material.
