Abstract

A water jet edge trimming station for trimming the edges of coated paper during on-machine operation includes backsplash compensating features. The edge trimming station has a cutting station over which the web travels to be cut. The water jet travels along a water jet axis to a point of impingement at the cutting station to cut the web. The cutting station has an effluent receiving aperture at the point of impingement. A negative pressure mixing zone located below the aperture draws effluent by-products or backsplash associated with cutting of the web below the cutting surface of the web. The water jet axis is offset a first predetermined angle chosen relative to a normal axis passing at right angles through the point of impingement to reduce backsplash. The water axis jet is rotated about the normal axis by a second predetermined angle to direct the effluent by-products away from the water jet nozzle and the traveling web. The water jet cutting apparatus has positive air pressure chamber surrounding the nozzle head of the water jet to maintain an air flow over the nozzle head driving effluent backsplash away from the nozzle head.
