ABSTRACT:
An apparatus for cutting a newly formed continuous sheet being transported longitudinally along a belt conveyor, and particularly a newly formed gypsum board sheet, the cutting taking place in a direction transverse to the direction of movement of the sheet, comprising a frame, a high pressure fluid jet cutter mounted to move obliquely with respect to the direction of the moving sheet, wherein the vector component of velocity of the forward motion of the cutter equals the forward velocity of the moving sheet, and means for rotating the support on which the jet cutter is mounted to another oblique position so that a successive cut may be made from the other side. In an improved embodiment, tank means is arranged to catch the spent fluid from the jet cutter so that the cutter may traverse the moving sheet from either side successively without turning off the fluid jet.
