The The web of paper II is preferably removed from pressure which has been Successfully e p yed s 55 l or sufllcient to cause a compression of about one thirty-second of an inch in the rubber roll jacket and a contact zone between the roller of about seven-eighths of an inch in width. This condition isdiagrammatically represented on an enlarged scale in Fig. 8.

From an examination of Fig. 8, it will be seen that sheets fed between the rolls are subjected to a gradually, increasing pressure until the maxi-. mum embossing pressure is applied in the middle of the width of the contact zone. The pressure applied to sheets to be embossed starting at the initial point A of contact between the rolls rises fairly rapidly as the sheet progresses between the rolls until about one-fifth or some such portion of the width of the zone of contact is traversed. Then the applied pressure rises somewhat more slowly until the middle point of maximum pressure is reached. From there on the pressure first slowly, and then more rapidly decreases until the embossed sheet emerges from the contact zone. If the normal pressure applied is, say 250 pounds per lineal inch of the contact zone, the maximum pressure, at the middle of the contact zone will be considerably greater, as indicated in the diagram Fig. 8.

It will be observed that the creped tissue sheets are gripped over a band corresponding to the zone of contact between the rolls. By this means, the sheets are effectively supported and held against slipping or creeping between the rolls and the initial area of the webs or sheets is not reduced as a result of the embossing. In other words, the embossing requires actual stretching of the sheet material, rather than a gathering effect such as results from conventional embossing methods where the embossing is effected along a line of contact between rolls, as distinguished from an area of contact as in the disclosure in this application.

By reference to Fig. 2, it will be noted that the multi-ply creped tissue web has the striations of its creping extending transversely of the length of the web, so that when the web is embossed between the steel roll I! and the rubber covered roll -l9, the longitudinal direction of the elongated embossing pattern will extend transversely of the creping of the paper. As indicated in the drawing, especially Fig. 7, the described embossing forms a pattern which is not materially coarser than the creping of the paper, and serves to break up the continuity of the creping. Theembossed sheets tend to have or approximate the appearanceof woven textile material such as linen, the creping in the sheets serving to produce the characteristic irregularity of such material. The embossed web may then be severed into independent cleansing tissue sheets or otherwise treated to prepare the web for marketing.

One design of embossing such as typified by that herein illustrated is such that there are approximately 30 circumferentially extending lines of embossing to the inch and such that there are about 24 transversely extending lines to the inch. A pattern of such proportions produces excellent results.

The speed of rotation of the rolls appears to be of no great importance and they may be driven at any speed desired or necessary for the required production. The rolls are not geared together but operate independently, only the steel embossing roll being positively driven. The-other'roll will of course follow the driven roll incident to the operating contact between their surfaces.

The embossing of paper napkins and other paper articles with various designs is of course an old practice but so far as known, no one has heretofore attempted to emboss crepe tissue paper with an all-over design for any purpose such as herein contemplated. Paper embossing as practiced in the prior practical art is usually accomplished between a steel embossing roll and a hard paper or other composition roll which has been run in with the steel roll so as to have a permanent impression on its surface which is complementary to the raised design of the embossing of the steel roll. This form of apparatus cannot successfully be used for the purpose of embossing crepe tissue paper, for the reason that when crepe tissue paper is embossed in that manner the resulting product is hardened or stiffened so as to become wholly unfit for any of the uses to which creped tissue paper is put because of its normal softness.

The described arrangement is illustrative of one practical method and suitable apparatus for producing an improved, inherently soft tissue paper product. Changes may be made in the described arrangement without departing from the spirit of the invention, the scope of which should be determined by reference to the following claims, the same being construed as broadly as possible consistent with the state of the art.

We claim:

1. The method of making a tissue paper sheet suitable for facial and like uses, which consists in conducting a creped tissue paper sheet through a pressure zone of substantial length whereby the concentration of pressure at any point of the pressure zone is insuflicient to produce any hardening of the material while simultaneously, by means of said pressure, forming in the sheet an all-over pattern not materially coarser than the creping in the sheet.

2. The method of making a crepe tissue paper sheet suitable for facial and like uses, which consists in conducting a creped tissue paper sheet through the nip of a pair of embossing rolls, the pattern roll of which is made of hard material bearing an all-over design not materially coarser than the original creping in the paper sheet, and the platen roll of which has a smooth, soft, resilient rubber surface, said rolls being so juxtaposed and the softness of said platen rubber being such that the rubber of the platen roll is compressed to form said nip of substantial length whereby the concentration of, pressure at any point of said nip is insuilicient to harden the crepe tissue paper while the pressure is sufficient to impress the pattern of said pattern roll in said paper.

3. A paper article of such softness as to be suitable for facial and like uses, comprising a creped tissue paper sheet having an all-over pattern embossed therein, the pattern being not materially coarser than the creping and comprising a multiplicity of elements separated by interposed areas of the sheet which remain substantially in their initially soft condition.
