Abstract
A water jet web slitting apparatus slits a web at a plurality of locations across the web into webs of smaller width in a winder. The water jet web slitting apparatus utilizes a water jet cutter to slit the web. The water jet cutter has a support plate with a pattern of suction apertures located surrounding the cutting aperture of the water jet cutter through which negative pressure is applied to hold the web against the support plate adjacent the water jet cutting apparatus and to prevent the web from fluttering or moving relative to the support plate notwithstanding whether the web is travelling or temporarily at a stopped position. This permits for the water jet to be run continuously without having to be turned off and restarted when the web travel is temporarily stopped and started again because the continually running jet does not re-wet the surface of the web or the edges cut into the web.
