Patented July 16, 19 35 '4 I UNITED STA'lES PATENT orrien METHOD OF AND MEANS FOR FEEDING SHEET MATERIAL Arthur Worm ser, Offenbach, near Frankfort-om the-Main, Germany Application March-1d, 1935, Serial No. 11,021 In Germany (October 19, 1932 5 Claims. (Cl. 271-58) The invention relates to a method of and means previously overlapped the front end of the sheet for feeding sheet material to a printing or other 2, has now passed beyond the front gauges machine, and the new feature is that the side At this moment the front gauges d liberate aligning gauge is timed so as to engage and align the perfectly aligned sheet 2, as shown in Fig. 4,

One great advantage of this arrangement is The front gauges 4 now rise again, in order to that the usual side aligning gauge which has stop and align the following sheet 3, while the 10 answered all requirements of practice can be back end of the sheet 2 overlaps'the front gauges it used. 4 and the sheet 3, as shown in Fig. l for the previ= On the accompanying drawing my invention is one sheet. The cycle of Operation is then re illustrated by way of example, peated.
