Abstract

16,816. Dow, W. S., and Smith, E. J. July 31. Rotary machines. -In machines known as ' web all size machines,' the web is run through the machine at a constant speed for all sizes of sheet, and the speed of the printing-cylinder is varied. The web is printed, perfected, superimposed, and folded before the sheets are cut off from the web, carrying tapes being dispensed with. The forme must not cover more than half the forme cylinder B. Four printing- mechanisms may be used, one pair for printing on one side and the other for perfecting, the driving- mechanism being placed between the two pairs. At the time of printing, the speed of the cylinders is that of the web, but, after printing, they are made to rotate more rapidly, the speed depending on the size of sheet to be printed. This may be effected by mounting the driven wheel F in a vibrating frame and gearing it with a non-circular wheel E, a circular wheel on the same shaft gearing with the cylinder trains. Pairs of non-circular wheels in gear, or other means, may be used. Two type cylinders running at varying speeds and working with one impression cylinder at constant speed may sometimes be employed.
