A method and machine for folding, stacking and separating continuous forms in a moving web, the continuous forms web being prefabricated with regard to width, margin line holes and transverse perforations intended for zigzag folding of the web to form it into a stack after it has been provided with print in a printer having a supply of series of preferably personalized forms, wherein each series includes an initial form marked with an address and optionally with a separation mark a first system having feed means for the web which cooperation with the line holes advance the web in controlled register, and means for cutting the web on electronic command from a sensor which reacts to the separation mark or, alternatively, on electronic command from the printer, and a second system comprising a driven feed device for advancing the web and a swinging waddling device, the web passing through the waddling device and being formed during the swinging movements thereof into a zigzag folded stack, and further means for squeezing and holding down the folded stack.

A method of folding, stacking and separating a single web equipped with equally spaced lines of transverse perforation defining form lengths comprising the steps of unwinding said web from a source roll and advancing said web along a predetermined path in which said web is sequentially subjected to printing, softening along said perforation lines, zig-zag folding to form a stack, and alternate squeezing and holding down the developing folded edges portions of said stack, and intermittently severing said web along a perforation line to end one stack and commence another, said softening, squeezing and holding down steps cooperating to develop stacks of printed form lengths in an in-line operation without the need for pre-folding the web before zig-zag folding, said step of zig-zag folding including oscillating a chute means and, at the start of each stack always positioning said chute means at the same end of the oscillation path.
