METHOD OF MAKING A MOLDED PAPER WEB
20210395948 · 2021-12-23 ·

A method of making a molded paper web. The method includes forming a nascent web from an aqueous solution of papermaking fibers, moving a dewatered web on a transfer surface, and applying a vacuum at a molding zone defined between the transfer surface and a molding roll. The molding roll includes a permeable patterned surface on an exterior of the molding roll. The method also includes transferring the dewatered web from the transfer surface to the permeable patterned surface at the molding zone. The vacuum is applied during the transferring of the dewatered web, and the papermaking fibers of the dewatered web are (i) redistributed on the permeable patterned surface and (ii) drawn into a plurality of recess of the permeable patterned surface, in order to form the molded paper web.
