Abstract
A roll of embossed paper towelling in which the embossing comprises lands and valleys between the lands wherein the lands are in rows extending at an acute angle to the longitudinal direction of the towelling. The acute angle of the rows of lands offsets each land with respect to the lands of the next adjacent turns or layers of the towel in the roll. That causes the layers to be held apart, and the desirable characteristics of the towels are preserved. There is also apparatus and a method for producing the embossed paper towelling. An embossing roll has a continuous spiral row of embossing elements or patterns which produce the embossing on the towelling. The spiral rows are at an angle of the order of five degrees from the longitudinal edges of the towels, i.e., the edges extending in the direction of the embossed sheet.
