Title: Improvements in or relating to driving gear for paper rolls of rotary printing machines
IPC: B65H16/10
Filed: 1926-04-24
Abstract: 251,297. Maschinenfabrik Augsburg- N³rnberg, Akt.-Ges. April 27, 1925, [Convention date]. Feeding webs.-In a web-feeding mechanism for rotary printing-machines in which the web roll is automatically traversed along a spindle, by means of a device operated by the rotation of the roll as it is unwound, so as to keep the roll in contact with a feeding-belt, means are provided for keeping the pressure of the roll on the belt substantially constant irrespective of the thickness of the web. The roll spindle c is provided with a worm d engaging a worm wheel e formed as a nut engaging a screwed spindle f so that as the roll is rotated it is raised to keep it in contact with a feeding-belt b mounted on rollers h, i. The roller i is mounted between springs l, m, and its movements are adapted to actuate switches r, o controlling a reversible motor p geared to the spindle f. The parts are arranged so that with normal pressure of the roll on the belt, both switches are open and the motor at rest. If a web thinner than normal is being fed, the pressure on the belt increases so that the roller i is pulled down against the action of the spring l and the switch o is closed. The motor p is thus driven in a direction to lower the roll until the rise of the roller i again opens the switch o. If a thick web is being fed, the pressure on the belt decreases and the spring l raises the roller i so that the switch r is closed. The motor p is thus driven to raise the roller until by the increased pressure on the belt the roller is again drawn down and the switch r opened. Magnets may be employed instead of springs m, l.

In soldering the side seams of can bodies the bodies are fed axially with the side seams lowermost, the side seams are preheated at least to the melting point of tin as they are fed along and a crown of low tin content solder is applied to the preheated seams, the solder being heated to a temperature which added to the temperature to which the seams are preheated gives a total twice that necessary in the solder to ensure its inflowing into the seams by capillary action. Cylindrical can bodies 9 are fed step by step from a forming device 5, Fig. 1, along a horn 6 where they are engaged by lugs on a continuously moving chain 8 and fed into a horse 10 with their side seams in line and exposed through the bottom of the horse. The bodies pass firstly over a high frequency, e.g. 450,000 cycles per sec., induction coil 12, through which coolant is flowed, to preheat the seams to 450‹ F. The bodies are then fed over the solder applying means 13 comprising a solder pot having a long reservoir chamber 35, Fig. 4, and a short filling chamber 36 separated by a wall 33 terminating short of the base of the pot, the solder of 98 per cent lead, 2 per cent tin, being heated to 950‹ F. by gas burners, preferably temperature controlled. Solder is pumped by a multiple thread screw-pump 63 into a cup 58 at the upper end of a pump casing sleeve 57 to be delivered from slots in the base of the cup into a head chamber 41 above the level of the reservoir. Solder in the chamber 41, the level of which is determined by an overflow pipe 66 delivering into the reservoir enters a valve tube 52 through ports 56 and through an aperture controlled by a needle valve 54 enters an L-shaped supply tube 46. The tube 46 supplies a nozzle 76 having a vertical bore 78, Fig. 8, leading into a horizontal bore 79 opening_ into the narrow slot 80 on the tapered surface of the nozzle. The can seams are fed over the opening 80 to receive solder therefrom. Inert gas, e.g. nitrogen is fed from pipes 68 to the space above the solder in the reservoir and in the chamber 41. In a modification the solder may be applied by a disc rotating out of contact with the cans, in a solder pot about an axis transverse to the direction of travel of the cans, the disc being driven so that its peripheral speed is higher than that of the can movement.
