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 cutting station. After proceeding through a cutting station, the web reaches a folding station, where the web is folded into a folded segment. In yet another embodiment of the invention, the cutting station is provided with a knife roll and a backing member which may be an anvil roll, a bed roll or a stationary anvil. In a further embodiment, the cutting station is replaced with a metering station having a pair of driven metering rolls, one of which is contiguous with a folding cylinder and includes vacuum ports for releasably holding a portion of the web.
