Abstract: 428,441. Feeding webs. KOHLER, F. W., 410, North Michigan Avenue, Chicago, U.S.A. Aug. 9, 1933, No. 22296. Void [Abridged as open to inspection under Sect. 91 of the Acts, March 1, 1934]. [Class 100 (i)] A device for delivering paper to printing- presses comprises means for movably mounting a plurality of rolls in position and for connecting the web of the new roll with that of the expiring roll without stopping the press, a device for severing the expiring web after the new web has been attached thereto, and automatic reset mechanism for the severing-device. The rolls 3, 4, 5, Fig. 2, are carried by supporting arms 2 on a shaft 1, and driven by belts 9, which are maintained taut and in contact with the rolls by weighted rollers 14. When the web from roll 3 is nearly exhausted, roll 4, after being pasted, is rotated into contact with it, and is speeded up by the belts 9. The two webs 21, 19 are fed together into the printing- machine and pass between a light source 22 and a photoelectric cell 23. The double web varies the amount of light transmitted, and by means of a relay 27 energizes a solenoid 29, which pulls over a lever 30, Fig. 6, and unlatches a cam 33 mounted on a shaft 34. Also mounted on the shaft 34 are arms 37 carrying a cutter blade 36, and gear sectors 38 (shown separately in Fig. 6), meshing with sectors 39 fast to a shaft 40 which carries levers 41. Rods 42, carrying springs 44, are pivoted to the arm 41 and pass through pivoted guides 43. When the cam 34 is unlatched the springs 44 rotate the shafts 40, 34, and the cutter blade 36 severs the web 19. Simultaneously a lever 47<a> is thrown over by a pin 42<a> on one of the rods 42, thus closing a switch 48, 49 and completing a circuit through a " thrustor unit 52. In the unit 52 an electric motor forces a liquid through an internal valve under a piston, thus raising the piston and connecting rods 58. The rods 58 are connected through a lever 60, link 64, and pin-and-slot mechanism 65, 66 with an arm 67 rigidly mounted on the shaft 40. The " thrustor," acting shortly after the cutting- mechanism, rotates the shafts 34, 40 in the opposite direction to a position in which the lever 30 can again latch the cam 33, and also opens the switch 48, 49. A switch 70 is provided which can be used to disconnect the photo-electric relay so that the cutting operation may be initiated by hand.
