Abstract
A web folder apparatus for folding a running web at fixed intervals into zig-zag folds along fold lines which traverse the web. The apparatus has first and second folding cylinders adapted to rotate in opposite directions each of which has a non-rotatable gripping means spaced from and associated therewith to selectively grip a portion of the web along a fold line, each of the cylinders has vacuum means on the periphery thereof to assist in carrying the web around a portion of each cylinder to contact an associated gripping means, and at least one of the cylinders has air pressure ports in the periphery thereof which are circumferentially spaced from the vacuum means and through which air is adapted to flow radially outwardly of the cylinder to urge the web in contact with the cylinder away therefrom and to propel it in the direction of the folded web.
