Method of manufacturing embossed paper products
Abstract
Abstract A method for continuously embossing a pattern in a paper web. A pair of parallel rollers having a nip therebetween provided. The rollers are biased together while the web is between the rollers. Circumferentially alternating strips having an embossing pattern and axial relief grooves at least coextensive in length with the width of the paper web are provided in the outer periphery of one of the rollers. An interengaging embossing pattern is provided in the other roller. The biasing pressure is intermittently relieved between the rotating rollers when the axial grooves are rotated to a position at the nip between the rollers thereby causing the rollers to jump together by the biasing pressure. The impact of the movement is absorbed by the paper web to set the pattern in the paper web.
