    Abstract: 142,117. Eastern Manufacturing Co., (Assignees of Guild, H. J.). Dec. 9, 1916, [Convention date]. Embossing. - A 1 i n e n or fabric-like appearance is produced on the surface of paper by passing it in contact with flexible marking bands between a pair of pressure-applying rollers of which one has a hard surface while the other will yield sufficiently to effect a slight relative motion between the paper and the bands while under pressure, thus producing a polish on the surface of the paper. In the machine shown in Fig. 1 vertical frames 2 are provided with slots 3 in which are mounted the bearing boxes 4, 5, 6 for rollers 10, 11, 12, the roller 11 being made of a softer material than the rollers 10, 12. Pressure is applied by screws 14 engaging the uppermost boxes 6. Arms 17 are connected to the frames 2 by pins 18, and are supported by stays 37 and adjustable screws 19. Between the arms 17 are mounted guiding-rollers 21, 22, 23, for an endless embossing-web 24, to the part 24 of which the paper P in the form of sheets or web is fed, endless cords 32 retaining the paper on the belt. The roller 23 is mounted in a slide 25 on the arm 17, which has a rack 29 engaging a pinion 27 on a shaft 26 carried by the slide 25. A pulley 28, from which a weight 31 is suspended by a cord 30, is carried by the shaft 26, so as to move the slide 25 in the direction to apply tension to the web 24. An embossing web 60 for the other side of the paper pa.sses over the rollers 50, 51, 52, 53 in arms 49, pivoted at 47 to the frame 2 and stayed by bars 48, a tensioning-device similar to that already described being applied to the roller 53. The web 60 also passes around the rollers 10 - - 12 a.s shown in Fig. 2, the paper being carried between the webs 24 and 60 around the roller 11 and delivered by a belt 65 to a table 64. The roller 11 is preferably made of coinpressed paper fibre, and the rollers 10, 12 of cast iron, so that as the paper passes between the embossing-webs under pressure, there is a slight slip between the paper and the webs, owing to the compression of the roller 11, which produces a superficial polish or finish on the paper. A driving-pulley 66 is secured to the shaft of the roller 10 from which the other rollers are driven by friction. One of the rollers 10, 12 may be omitted so that the paper is subject to only one impression, or further sets of rollers may be provided to apply more than two impressions. Etched or engraved bands may be used in place of the embossing-webs.
