Abstract

A water jet cutting apparatus for use in a papermaking machine has an elongated support beam that extends across the width of the web. The water jet cutting apparatus utilizes a free spinning hose wheel about which the water jet hose supplying water to a water jet nozzle is guided and stretched. The wheel is mounted for movement with a slower moving carriage along the beam adjacent a faster moving carriage carrying the water jet nozzle. The slower moving carriage moves along the beam at speeds which are one half the speeds at which the faster moving carriage moves across the beam. During this movement of the second slower moving carriage, the wheel reels the hose thereabout to provide a travelling intermediate support for the hose. The hose wheel supports the weight of the hose and maintains it in alignment with the faster moving carriage so that less strain and stress is placed on the hose and the ends of the hose connected to the water jet nozzle during movement of the water jet nozzle across the beam. The water jet cutting apparatus has a preferred application as a tip cutting device in a reel turn-up application in a papermaking machine when two sets of faster and slower moving carriages are arranged for movement on opposite sides of the support beam to move towards each other in directions transverse to the web.
