1335207 Feeding and folding sheets R FUNK & CO Inc 3 Nov 1970 [3 Nov 1969] 52296/70 Heading B8R Sheets of various widths and having data marks in selected positions 180-185 are delivered from a printer P to an inclined conveyer I and a horizontal conveyer H, Fig. 2, laterally inclined tapes of which register them against a guide A, and come to rest against a gate G. Detector S1 initiates the movement of the conveyers, which are stopped after a given time until the next sheet reaches the detector. The data marks are sensed and control a label printer L to apply the relevant label. The sheet width is directed by photo-electric scanners R1, R2, R3, which activate a selected one of a plurality of folding units in a folder F. The folder comprises three units. In the first unit, for the smallest sheets, a sheet is folded transversely by rollers 82, Fig. 22, a stop 22B and a gate 82<1>, and delivered by a conveyer 83 to a tidy 84. In the second unit, for layer sheets, the folded sheet 91, Fig. 23, on the conveyer 83 is then folded longitudinally by a blade 93, Fig. 24, and rollers 92 and delivered by a lateral conveyer 95 to a tray 97. In the third unit, for the largest sheets, the transversely folded sheet is longitudinally folded by a blade 104, Fig. 26, and rollers 103, fed downwardly to a stop 108, and then folded longitudinally a second time by a blade 107 and rollers 106.
