Publication number: 20140044883Abstract: A paper tissue and products made from paper tissue, such as paper handkerchiefs, facial tissues, bath and cosmetic tissues, paper tissue wipes of any kinds and the like. The invention describes both the process for making a smooth and absorbent lotioned paper tissue, with high transferability of the lotion. The process steps comprises the steps of (a) providing a paper tissue web continuously moving next to a lotion application unit comprising at least one rotating surface, (b) transferring said lotion onto one rotating surface, (c) expulsing said lotion from the said rotating surface into a stream of lotion droplets, by primarily the centrifugal force of the rotation of said rotating surface, (d) intercepting said paper tissue with said stream of lotion droplets. The invention also describes a paper tissue comprising a lotion distributed as discrete deposits on its surface. The deposits have a high local concentration of lotion and cover a relatively small area of the tissue.Type: ApplicationFiled: October 11, 2013Publication date: February 13, 2014Applicant: The Procter & Gamble CompanyInventors: Joerg KLEINWAECHTER, Dirk SAEVECKE, Curtis Allen MARCOTT, Luigi DI GIROLAMO-GALASSO
