Abstract: A machine folds a sheet by inserting a sheet in the bight between a pair of folder rollers, which may be varied in their separation to accomodate sheets having different folding characteristics. The sheet to be folded is first located in a preinserting position, lying in a plane which spans the gap between the folder rollers, and insertion is made by an inserter blade which strikes the sheet at its medial area and drives it into the roller bight. To condition the sheet for an accurate fold, a shuttle supports the sheet spanning the aforesaid gap until the time just prior to the inserter blade striking the sheet. The sheet may be tensioned or pulled taut in its pre-inserting position.

Abstract: A FEEDER FOR SHEETS OR SIGNATURES, FEEDING FROM A SUPPLY HOPPER TO A CONVEYOR, IS CONSTRUCTED TO HAVE A SINGLE EXTRACTING CYLINDER OPERATING BETWEEN THE SUPPLY AND THE HOPPER, EFFECTIVE TO FEED TWO SHEETS PER CYCLE OF REVOLUTION. A SHEET RELEASED FROM THE EXTRACTING CYLINDER IS SETTLED ON THE CONVEYOR BY MEANS OF AN AIR BLAST. FURTHER, THE ARRANGEMENT MAKES POSSIBLE AN IMPROVED SYSTEM FOR DEMOGRAPHIC SIGNATURE GATHERING.
