Abstract: 14,508. Wernert, J. June 20, 1911, [Convention date]. Roller copying-presses. -A roller copying-press is so constructed that only the paper necessary for the copy is moistened, the moistening of this paper also serving to secure a gummed binding - strip to the copying-paper, the binding - strip and copying web being fed from rolls arranged inside a drum through a slot in the drum. The strip and web are perforated on the drum before being moistened, and, as soon as moistened, the letter is fed from a feed-board by rollers which are raised by the rotation of the drum into contact with a copying- roller coacting with the drum. The copy is cut off by a radially movable knife in the drum coacting with a fixed knife, and the copy is delivered by oscillating arms formed with hooks for engaging the perforations through the binding - strip and the copy. As shown, a drum 1 is fitted internally with a roll 2 of copying - paper, and a smaller roll 3 of binding- paper which is of less width than the copying- paper. The copying and binding webs pass between rollers 4, 5 of which the roller 4 is formed with fixed outer portions and a free inner portion corresponding to the width of the strip 3, and the roller 5 is formed with free outer portions and a fixed inner portion. Gears on the rollers 4, 5 are adapted to coact with adjustable circular racks fixed to the frame of the machine, and, owing to the construction above indicated, when a gear on the roller 4 engages a rack 8, the web 2 only is rotated and passes through a slot 30 in the drum 1. The roller 5 is rotated only when a gear on it engages a second circular rack, and then both webs 2, 3 are fed forward to a certain extent. The roller 5 is formed with flattened sides to prevent jamming of the copying-web when it is being fed alone. On further rotation of the drum 1, a wiping-device 11 presses the paper close to the drum, and then a pair of punches 12 are moved outwards radially by the action of inclines 14 on shoulders 13 on the punches, and coact with matrices 16 to perforate the copying-paper and binding-strip. The matrices are suspended from the axle of the drum 1, and are given a movement about this axle during the act of perforation. A. damping-roller 17 fed by a band 19 from a reservoir 18 damps the copying - paper and also serves to join it to the binding-strip. and then the letter to be copied is fed by hand, or by means of rollers 21 on an arm 22 which is raised by the shoulders 13 on the drum to coact with the copying-roll 20 in order to forward the sheets from the table 23. The letter and copying-web then pass between the roll 20 and drum 1, and the copying is effected. The copy is then severed by means of a radially movable knife 30, actuated by a projection 25 and incline 26, and a spring - depressed fixed knife 28 with a V - shaped cutting - edge, so arranged that the cutting proceeds from both edges towards the centre. The cut copies are received on hooked arms 32 carried by arms 33 oscillated by a crank 34 and link 31. The machine may be used for forming copies which are unperforated and not reinforced by a binding-strip.
