Abstract: 16,965. Stettner, P., and Hellmann, A. Aug. 22. Cutting-machines for paper; paper, winding; gumming, pasting, and the like.-The object is to provide hard-wound rolls of paper of a diameter suitable for the market, the paper being wound direct from the papermachine. The machine described contains two winding- devices which can be use d alternately so that the paper can be wound continuously. The paper is fed by hand to rollers 2 and passes under the cutting-apparatus 3. The end is cut square and the cut-off end passes down the table 5 as waste. The table 5 then turns about its pivot 5<1> and closes the space between itself and a cover 7. The squared end passes down beneath the table and is guided by a hand-adjusted flap 27 and pendulum guide 26 over the frame 28 to the rotating pressure roller 9. It is pressed against this roller by a number of rollers 10 mounted on one shaft and held against the roller 9 by springs 11. Mounted below the rollers 10 is a hollow gumming-cylinder 14, Fig. 6, from which project a number of porous wipers which dip into the adhesive with which the cylinder 14 is filled. The pressure roller 9 is pressed against the spindle on which the paper is wound by the action of weights 24 hung on a roller, the axle of which carries a toothed wheel gearing with a rack 25, to the end of which the slidable bearings of the roller 9 are fixed. Thecutting-apparatus is slidably mounted in bearings 2<3>, Fig. 7, and is connected at its upper end with ropes S' secured to a roller Z<2>, the table 5 being secured to the same roller by the cord Z. The shaft of the roller Z<2> also carries a roller Z<3>, to which draw-ropes from rods 4 are secured, and a hook-lever 18, which supports a weighted lever 19. A pull on either rod 4 raises the cutting-apparatus, closes the space between the table 5 and the cover 7, and releases the lever 19. On the release of the rod 4, the cutter falls by its own weight against a leaden cutting-table B and severs the paper. The arm 19<2> of the weighted lever 19 puts into gear the two portions K<1>, K of a clutch, and the shaft 16, to which the part K of the clutch is feathered, is rotated. Eccentrics 20<1> on the shaft 16, one for each winding- device, reciprocate rods 20, projections on which lift levers 21, Fig. 6. These levers each engage a lug on a weighted lever 22 fixed to the axle of the gumming-roller 14 and maintain the gumming-wipers out of contact with the paper. When the lever 21 is raised, the weighted lever 22 falls and causes the gumming-wipers to apply adhesive to the end of the paper. The adhesive causes the end of the paper to stick to the spindle 1 or to a tube on which the paper may be wound. If the spindle or tube is gummed, it is sufficient to damp the end of the paper. The gearing actuated from the shaft 2<1> is so arranged that gumming takes place as soon as the end of the paper reaches the gumming - apparatus. Should the paper be torn before the roll is completed, the ends are gummed together by adjusting the stop on the rod 20 so as to bring the gumming - wipers into action on the machine being re-started. From the gumming-apparatus the paper passes down a slotted sheet - metal guide to the winding-spindle 1. When very thin paper is to be wound, the end is assisted down the guide by a blast of air from a perforated metal pipe 13 connected with a chamber containing compressed air. When the first roll is full, the flap 27 is reversed, the paper cut as before, and the new end guided to the second winding-spindle.
