Patented Feb. 11, Hi3.

To all whom it may concern which there is Be it known that l, KUNO FRANZ, a citizen of the Empire of Germany, residingat.

Franlttort-on-the-Main, Germany, have invented certain new and useful Improvements in the Manufacture on the' Pa er- Machine of Paper Having Relief Like E ect, of which the following is a specification.

My present invention relates to a modification of the process described and claimed in U. S. Patent No. 918525, according to produced on the flpaper-machine paper havmg a relief-like e ect by impressing the paper-web while on the wirecloth or on the wet-felt with figured elevations and depressions by means of rollers which are embossed with relief patterns, by

then dyeing the paper web thus prepared in the usual manner either by means of felts which (ii at one end in a color trough and trail on t e paper web, or by means of nozzles by which dye-solutions are sprayed on the web at an'acute angle, and by finally finishing the paper in the usual manner. I have found that papers with such relief-like effects can also be produced by a modifier tion of the above mentioned pr cess, which consists in using instead of the figured rollers, simpler means for producing elevations and depressions on the'paper-web while it is still on thewire-cloth or on the wet-felt. For instance, cloths, brushes, sieve-rollers (dandy rollers), felts and the like may be caused to trail on the paper web or to rotate on it in a suitable manner, Ur compressed the surface of the paper-web may be produced icy other means (scratching it'with nails and the like). lit the paper-web so prepared is then dyed and finishedin the manner. indicated in U. S Patent as.

918525, relief like sheets are" produced.

Apart from the fact that the new method of carryin out the process in question is siniler and causes less expenses-owing tothe 2 red rollers being dis ensed with-it perirregular patterns nuts the production [o according to the means chosen, whereas view; Fig. 3 is an end elevation of a brush roll; F 1g. 4 is a side elevation of a trailing felt 1dev ce; and Fig. 5 is an end elevation ot a ro Referring to the drawings; 2 is a. wire cloth or wetfelt carrying the layer or web of paper; A is a device for mechanically producing directly on the web of paper haphazardly arranged elevations and depressions, which in this instance may he a dandy roll mounted in suitable journals but not driven except by its contact with the web; 3, 3, 3 are suit-ably arranged jet pipes supported above the web for spraying color on the elevations of the web; 4, a are finishing rolls; 5 is a brush foicleanin the upper roll; 6, 6 are the usual suction fioxes.

.As shown in Fig. 3, the means to form the elevations and depressions is a brush roll A; In Fig. 4 is shown another means for producing the same efi'ect, comprising a cross-bar an which is attached a trailing felt A In Fig. 5 is shown another modification which consists of a roll A provided with projections 8, this roll being mounted in the same manner as the roll A, to be rotated by its contact with the web.

In operation, whichever form of device he used, a series of haphazardly arranged elevations and depressions are produced in the partly disiccatedpaper web, which, after hemg colored and finished, produces a sheet having thereon irregularly arranged shaded designs.

Having now particularly described my in;- vention what I claimis:

. 1. The process of manufacturing paper having a relief-litre cfi'ect which consists in: mechanically prfiu'cing directly on the paper web by haphazard occurrence, while in a partly desiccated condition on the wire cloth or wet felt, elevations and depressions applying color to the elevations only 0' the web and finally finishing the paper in the usual manner.

2. The process of manufacturing paper we having a relief-like ofiect which consists in subjectin the aper web, while in a partly deslccat con 'tion on the wire cloth or wet felt to the action of yielding-means arranged to produce haphazardly elevations and dc ressions, aa'lyin color to the elevations o y of the we and oily finish ing the paper in the usual manner.

,having a relief-like efi'ect which consists in' subjectin the aper web, while in a partly 3. The process of manufacturing paper desicca con 'tlon on the wire cloth or wet felt to the action oi rotating sieve-rolls arranged to produce irregularly elevations and depressions, appl ing color to the ele-' vations only of the we and finally finishing the pa er 1n the usual manner.

4. T e process of manufacturing paper having a relief-like effect, which consists 1n deslccate ing color to the elevations only of the we a and finally finishing the paper in the usual manner.

5. A palper web having in its up er surface a co ored desl having a re ief-like sions, applymg color to the elevations only 1 of the web and finally-finishing the paper in the usual manner. In testimony-whereof, I afiix my signature in presence of two witnesses. J
