Abstract: 120,264. Pierson, P., and Christenson, A. Nov. 3, 1917. Platen machines; offset machines; inking-apparatus; embossing; bronzing and the like. - Finished cigar bands are made from a web of paper by a single passage through a machine, the bands being sized, gilded, printed in various colours and embossed and the web being finally cut into strips of finished bands. The machine comprises a platen C carried by standards c<3> adjustably secured to frames c<7> which are reciprocated by cams c<5> on the main shaft F. The web passes from a roll B over pivoted aprons b<1>, b<3> and below the platen against which it is held by wires which are tightened by keys d<1>, d<2> and prevent the paper adhering to the printing forms. The web passes between pairs of feed rollers e, e<1>, J, J<1> e<10>, e<11>, e<2>, e<3>, which are rotated intermittently by ratchet and pawl mechanism operated from a bar 26, Fig. 6, connected to a crank 82, or a cam, which is driven from the main shaft F; the pawl bar 23 operating the feed roller e<2> is also connected through a pitman 97 and a self-adjusting roller 94 sliding in a slotted arm 93 to ratchet and pawl mechanism actuating a roll nal on which the strips of finished bands are wound, waxed paper from a roller n<5> being interposed between layers of the strips. As the web passes along the platen, each portion is impressed against forms G, Fig. 3, to receive a design in sizing and then receives a coat of bronze powder from a brush H, excess powder being removed by a brush H<1>. The feed rolls J, J<1> burnish the gilt design, the roll J being provided with a heater j. Prints in various colours are impressed as the web passes forms I, I<1>, I<2>, I<3> and heated forms L then emboss and varnish the bands, which are afterwards dried by the heated roll e<2> and cut to strips by shaped knives M, Figs. 3 and 9<b>, which co-operate with knives M<2> on the platen. The waste paper collects on the top of the platen. Spring-pressed U-shaped bars 200 are provided between the colour printing forms to assist in preventing the web from adhering to the forms. While the platen is raised, inks are supplied to the colour printing forms, size to the forms G and varnish to the forms L, by rolls i', i<2>, i<3>, g, @, Fig. 3, connected to a slide 50, Fig. 11, which is reciprocated by rods 53, 57, Fig. 3, actuated by a cam 52; the inking rolls are separated bv rolls 190 engaging grooves in the inking- table 46. The inking, sizing and varnishing rolls each co-operated with a distributor roll 47 and idler roll 47, Fig. 4<a>; at the end of the outward stroke, the distributor rolls 47 contact with rolls 63 supported below ink &c. containers 60 pivoted in holders 61, and the rolls 63 are rotated to supply ink &c. by spring-pulled pawl arms 67, which arms also act through levers 70 to oscillate the containers 60 to supply further ink &c. to the rolls 63 through co-operating slots in the containers 60 and holders 61. The bronze powder is supplied to the brush H from a container h<3>, Fig. 5<a>, and is distributed by a worm conveyor h<1>, the brush and conveyor being rotated step by step from the feed roll J through gearing; the excess powder is removed from the brush H<1> by a stationary brush h<2>, Fig. 3, and is delivered by a worm conveyer through a spout h<7>, Fig. 5<a>, to a container h<8>. Instead of the bronze powder, gold leaf may be applied to the web, forms G', Fig. 11, duplicates of the sizing forms, being then secured over a beater G<7>, Fig. 3; the gold leaf and a paper-supporting strip are supplied from a roll g<12>, Fig. 11, and are fed by a drum 100 which is rotated step by step by a spring-pulled pawl arm 103 operated by a stop 106 on the slide 50, the stroke of the pawl arm being varied by means of an adjustable strap 108.
