Abstract A power-operated cutter for cutting paper web being prepared in a papermaking machine. The cutter includes an elongated hollow casing extending across and adjacent the face of the paper web under preparation, and an elongated cylinder disposed within and extending along the casing. A plunger movable within the cylinder under the action of fluid under pressure introduced selectively to opposite ends of the cylinder is connected by a flexible line to a nozzle-type cutter movable along a path defined along the casing. A flexible hose extending from a hose collector disposed adjacent one end of the casing extends into the casing to a connection with the nozzle. The casing may be hingedly mounted on a support adjacent the collector, to permit it to be swung out of the way.
The cutter of claim 1, wherein said oPening is a slot, and a slide is mounted on said slot which supports said nozzle.
