A buckle chute folding machine is described which has a single selector knob which selects a variety of fold patterns by simultaneous adjustment of the position of a stop blade in a buckle chute and a deflector bar positionable with respect to a nip roller set to either prevent or allow a second fold to be executed. An automatic paper feed system is provided to feed sheets from a holder tray, each sheet advanced incrementally into the machine to preclude double or overlapped feeding of the sheets through the nip roller sets.

A stacking receiver is disclosed for collecting and edgewise stacking of a succession of folded sheets exiting a slot on the folding machine, the receiver including an angled wire frame member pivotally mounted to be able to be swung to an up position in which the apex of a corner formed on each of a pair of legs is aligned opposite the slot. The member is spring urged to the up position, and is gradually lowered as successive sheets are fed beneath each other and accumulate in a stack, forced against a confinement section extending up from the corner apex, the sheets in the stack resting on a holder section extending horizontally as the member assumes a full down position. A second member provides an ascending ramp allowing the sheets to descend from the slot onto the holder section.

Stacking receiver for a sheet folding machine

A table top buckle chute fold machine is disclosed in which improved and more reliable squaring of the paper to the folding rolls is accomplished by lightly driving an inserted sheet of paper with a friction roller against a selected one of several deflector assemblies. The deflector assemblies each include a deflector member spaced away from the rollers to direct the advancing edge of the paper inwardly so as to be abutted against the back of a recessed guide groove. An intermittently engaged drive roller causes the squared paper to be forcibly advanced against the groove, causing the sheet to buckle and be nipped between another pair of driven nip rollers, forming a first fold at the location determined by the location of the particular deflector assembly activated. A movable deflector back either routes the folded paper to an exit chute or to another abutment surface, causing buckling and nipping between another pair of nip rollers to optionally add a second fold to the already folded sheet of paper prior to exiting the machine.
