ABSTRACT:
A web folding machine for folding a continuously fed web into folded segments is disclosed. The machine includes a frame upon which the other components of the machine are mounted. A web supply provides continuous web material to these other components of the machine, with multiple feeds of the web material being processed in parallel relationship to one another. In one embodiment of the invention, web is pulled from a web supply by a pull roll station, which engages the web material to feed it at an approximately constant feed rate to a metering roll station. After proceeding through the metering roll station, the web reaches the folding station, where the web it is folded into a folded segment. In yet another embodiment of the invention, the web is first fed to a folding board that folds the web longitudinally. After the web is folded longitudinally by the folding board, it is fed to a pivoting marker web guide station that periodically pivots to vertically displace the web to create a marker. In a different embodiment of the invention, the folded segments are moved from the folding station to a packing station, which segregates the folded segments into accumulations and conveys the accumulations of folded segments away from the folding station.
