Abstract: 668,645. Feeding sheets. HARRIS-SEYBOLD CO. June 8, 1949 [June 9, 1948], No. 15250/49. Class 100 (i). Sheets are fed to a continuously-rotating cylinder 11 by a transfer cylinder 12 which is driven from the cylinder 11 e.g. by means such as described in Specification 506,718, whereby the cylinder 12 has a stationary period, an acceleration period, a period of constant speed rotation at the surface speed of cylinder 11, and a retardation period, the sheets being fed to front stops on the cylinder 12 by nipper rolls 38, 41, and the roll 38 being driven from the cylinder 12 at a surface speed above that of the cylinder 12 to over-feed the sheets to the stops. Grippers 56 on the cylinder 11 convey the sheets to the grippers 57 of a cylinder 10, which may be the impression cylinder of a printing - machine. Cylinder 11, driven by a gear 14, drives the cylinder 10 through gears 15, 16 and drives the cylinder 12 through a combination of cams and a segmental gear 17, substantially as described in Specification 506,718. The nipper roll 38 comprises a series of spaced discs on a shaft 37 carrying a gear 39 meshing with a gear 40 on the cylinder 12. Since the gear 40 is larger than the gear 17, the roll 38 is driven at a greater surface speed than the cylinder 12. The lower nipper roll 41 also comprises spaced discs on a shaft carried in arms keyed on a shaft 44 which is adapted to be rocked by a lever 43' from a cam 46 which rotates at the same angular speed as the cylinders 10, 11. During a short interval, beginning at about the stationary period of cylinder 12 and continuing into the acceleration period, the nipper roll 41 is raised to press a sheet against the driven roll 38 whereby the sheet is over-fed to the cylinder 12. Sheets may be brought singly or in an overlapping stream on to a feed board 13 by travelling tapes 48, and are registered in known manner, by front stops 49 on a rockable shaft 50, and also side-registered by known means. The sheets are over-fed by the nipper rolls to stops 52 on the cylinder 12, and then gripped by grippers 54 thereon. A guard (not shown), consisting of a series of sheet-metal fingers, is arranged above the sheet path to ensure that each sheet engages the front stops 52; this guard is automatically raised and lowered during each cycle. Brushes 59 (not shown) hold the sheets in engagement with the cylinder 12. Specifications 506,636 and 515,579 also are referred to.
