Abstract: 22,103. Marks, G. C., [Meisel, F.]. Oct. 13. Winding. - In a machine for slitting and winding webs of cloth, paper, &c., particularly paper for newspapers, into even compact rolls suitable for use on printing-presses, the web is drawn from a roll W, Fig. 1, and passes between feeding-rolls 12, 13, between two pairs of shafts carrying slitting- cutters, over a guide-roll 23, and around a winding-drum 24 to a roller 26, which is mounted in vertical slots and rests on the drum 24. A drum 31, mounted in swinging arms mounted on separate spindles 35 at the top of the frame 11, rests against the roller 26, or the roll wound thereon, this arrangement permitting the drum 31 to bear uniformly against the web roll even in cases where it is not cylindrical owing to the web being slightly thicker at one edge than the other. The drum 31 is driven by a chain 30 from one of its supporting- spindles, which is driven by a chain 28 from the drum 24. The roll 12 is driven by a belt, and transmits motion, through the wheels 18, 19, 20, 21, 22, 25, to the cutter shafts and the drum 24, the wheels 18, 25 being preferably equal in diameter and twice the diameter of the wheels 20, 22. The roll 13 is mounted in sliding bearings 14 adjustable towards and away from the roll 12 by cams on a hand-operated shaft 15. Fig. 6 shows a machine for further slitting the web, and re-winding, so as to produce a number of smaller rolls. The web is tensioned by passing around the stays C, D, and is then led between the shafts carrying the slitting- cutters, and over the drum 59, to the re-winding shaft 58, which is guided at the ends in vertical slots and rests on the drums 59, 60. Thin plates, carried by cylinders 59 mounted on a shaft 56 and resting on the web-rolls, complete the work of the slitting-cutters and keep the rolls separate. The ends of the shaft 56 slide in the vertical slots. Fingers engaging notches in the bearings of the outer slitting-cutter shaft, and fixed on a rock-shaft 72 provided with a handle 73, serve to separate the slitting-cutter shafts for threading up the web, and the outer shaft is adjustable longitudinally for separating the pairs of cutters, by means of a handle 76, formed with a screw-thread engaging in the end of the shaft bearing and bearing against the end of the shaft, which is pressed forward by a spring at the opposite end. The cutter shafts are driven slightly faster than the web by a train of wheels from one of the drum shafts, which are driven by a wheel 65 fixed on a shaft driven by a friction clutch. One part of the clutch is expanded into frictional engagement with the positivelydriven part by a lever 83, Fig. 7, and, when the web rolls attain the required diameter, the machine is stopped automatically. For this purpose, a pivoted lever 86 supported by a collar on a vertically-movable shaft 88 engages a lug 85 on the lever 83, and holds the clutch in engagement, and an adjustable arm 89 on the shaft 88 is set so that, when the rolls are the required size, the roll shaft lifts the arm and shaft 88, thus releasing the lever 83, which is then drawn back, to disengage the clutch, by a spring 84. For removing the rolls, the shaft 56 is lifted by hooks and chains passing round wheels on a shaft 50, which is rotated by a chain 52 and handle, and the vertical slot guides are hinged at one side to allow the rolls to be moved on to the shelf E. A collapsable shaft from or to which the web or webs may be drawn or re-wound is constructed with a central shaft 100 Figs. 14 and 15, surrounded by quadrant pieces 107 fixed to blocks 104 fitting in milled recesses 103 in the shaft. A similar series of recesses are formed at intervals along the shaft to receive other blocks fixed to the quadrants, and the blocks are formed with inclined slots 105 engaging pins 106 fixed across the recesses 103. The adjustment of the segments towards and away from the shaft is effected by turning a nut 109 which engages the screwed end of the shaft and is recessed to receive projections 111 fixed on the quadrants.
