700,419. Folding paper. PITNEY-BOWES, Inc. June 26, 1951 [July 21, 1950], No. 15150/51. Class 100 (1) In a sheet folding machine comprising sheet Folding rollers 12, 13 ... 15, sheet buckle shoots and stop elements 52, the sheet buckle shoots comprise a plurality of spaced flat plate structures 31, 32, vertically supported at right-angles to the folding rollers, each plate structure having a slotted area 51 therein including mouth portions 33a, 33b, providing access to the slotted area for the sheet to enter after passing through the folding rollers. The plate structures comprise two flat members 31, 32, one suspended within the other and may be made separately or from one integral plate, Fig. 8 (not shown). The folder comprises side plates 10 and tie rods 11, 11a ... 11g and upon the rods 11a ... 11d, the plates 31, 32 are supported, bayonet slots 42 being provided for embracing the rods. Movement of the plate 32 is further prevented by engagement of the edges 48 of a tray 46, mounted in slots 47 of the side plate 10, with the inside edge 41 of the plate 22. Feeding and receiving trays 57, 62 are provided. The rollers 12 ... 15 are mounted in bushings in the side plates 10 the rollers 13 ... 15 being mounted for slight radial movement away from roller 12 to accommodate thick sheets. Rollers 14 and 15 are spring urged into contact with roller 12 which is driven by a motor 28 having a spindle 27 and pulley 26 driving a belt 25 and pulley 24 on the axis of the roller 12. The stops 52 are adjustable by set screws 54. Owing to the small area of contact between the sheets and the machine any static charge built up on the surface of the sheet is negligible.
