METHOD AND APPARATUS FOR APPLYING FLUID TO AN INTAGLIO ROLL FOR TRANSFER TO A SOFT, ABSORBENT FIBROUS

摘要

Disclosed is a method and apparatus for applying fluid to an intaglio roll for subsequent transfer to a soft, absorbent fibrous web passing in contact with the intaglio roll. The fluid is flowed upwardly through a small unpressurized reservoir extending across the width of the intaglio roll, which forms a confining member of the reservoir and overflows a second confining member of the reservoir spaced from the intaglio roll. The fluid is flowed into the reservoir with uniform flow velocity profile across the width of the reservoir, created preferably by flowing the fluid against an impingement member prior to entering the reservoir. The intaglio roll is rotated upwardly through the reservoir to establish a first layer of fluid adhering to the roll above the reservoir and the intaglio roll is rotated past a unique pre-wipe member positioned adjacent the intaglio roll above the reservoir. The pre-wipe member uniformly distributes the fluid in the first layer across the width of the intaglio roll, assures filling the fluid carrying recesses with the fluid and establishes a reformed layer of fluid adhering to the roll above the pre-wipe member, the reformed layer having less thickness than the first layer. The intaglio roll is then rotated past a doctor blade positioned against the intaglio roll beyond the pre-wipe member to remove essentially all of the fluid adhering to the intaglio roll except the fluid within the fluid carrying recesses.
