Abstract

930,247. Feeding sheets. C. J. HEYWOOD. April 24, 1962 [April 27, 1961], No. 15302/61. Class 100 (1). Sheet-feeding apparatus capable of straightening or aligning sheets which are skewed before they are fed to a printing &c. machine, comprises two axially aligned rollers 3, 4, Fig. 1, which are separated but connected by a bearing or clutch 5 which permits differential rotation of each roller, and means for driving the rollers differentially. The sheets to be aligned may engage the rollers 3, 4 directly and be pressed thereon by idler rolls 6, or they may be conveyed by feed belts mounted on the rollers 3, 4. The roller 3 is driven by a belt 9 from a drive roller 7; and the roller 4 is also driven from the roller 7 by a belt 11 which can be moved transversely by an idler tensioning roller (not shown) over which the belt passes, the roller 4 being coned at 12 to receive the belt, so that the speed of the roller 4 may be varied at will. In a modification, the roller 7 is also coned to receive the belt 11. As shown in Fig. 7, there are two sheet-engaging rollers and drive rollers 3b, 4b and 7a, 7b, respectively, each joined by a coupling 5 which allows differential rotation of the rollers. The roller 3b is driven directly by a sprocket 8b and it drives the rollers 7a, 7b through belts 9, 11, respectively. The belt 11 is received on coned ends of the rollers 3b, 7b and the belt is movable transversely whereby the roller 7b may be driven at a speed which is different from that of the roller 7a. The roller 4b of the-feed roller is driven from the roller 7b by a belt 9. The sheets are fed from a stack 19 on to the feed roller 3b, 4b. There may be more than two sets of rollers to provide a cumulative effect on the inclination of the sheets being fed.
