ABSTRACT:
In a cylinder folder for zig-zag folding a flexible web, air is supplied to the region between the web and the cylinder where the web is separated from the cylinder by the web stripper. The air is pressure injected through hollow stripping pins and relieves the vacuum as the web leaves the cylinder, considerably improving the stripping of the web therefrom.
