A size press having a plurality of rollers for the deposition of a size bath on both sides of a running paper web. The running paper web cooperates with a first roller to pick up size from a trough disposed below the first roller. Downstream of the first roller are second, third and fourth rollers, which are so disposed relative one to the other that the second and third rollers form a pressure gap therebetween and the third and fourth rollers form a second pressure gap therebetween. The size deposited on the running paper web from the trough is uniformly and efficiently metered thereon, and sufficient time is provided for a uniform penetration of the size into the running paper web, thereby resulting in a homogeneously sized web. |
