Abstract: A papermaking process dry end slabbing method using high pressure fluid cutting moves generally parallel to a spool at the end of the papermaking process. The process removes multiple layers of unwanted paper which may be of the wrong grade, poor quality, mis-spooled or otherwise damaged from the spool. A first method uses a carriage mounting an articulated cutter. Vertically extensible pneumatic or hydraulic cylinders and anti-oscillation and thrust support telescopic stanchions displace the cutter in response to input from a set of sensors used to detect a surface of the paper. A track embedded in the floor guides the carriage generally parallel to the spool. The track can be a geared rack, a rail, a channel defined in the floor or a wire embedded in the floor. A driven pinion gear or wheel, undriven foot or wheel, or sensing equipment disposed within the carriage interacts with the track to guide the carriage.

Abstract: A paper cutter comprising: a bed for placing paper to be cut thereon; a rail mounted on the bed; a slider made slidable along the rail; and a rotary blade carried by the slider for cutting the paper as the slider is moved. Further comprised are springs for supporting the two ends of the rail therethrough on the bed so that the rail may move up and down. The rail has its lower face formed on its end edge with a cutting position determining face such that the slider is fitted on the rail in a position where the rotary blade runs along the positioning face. With this construction, the rail itself is supported in a floating state on the bed. As a result, the paper is cut with the rotary blade by lowering the floating rail with the depression of the slider and by clamping the paper under pressure only at the portion to be cut between the rail and the bed as the slider is moved.

Abstract: In a cutting device having a moving (disc) cutter and a fixed cutter which extends in a cutting direction, wherein the moving cutter moves along the fixed cutter, thereby cutting a medium which is interposed therebetween, a presser member which is movable together with a medium pressing interlocking plate is lowered to press on the medium to fix the same at a portion close to a cutting position since a bearing attached to the moving cutter engages with the medium pressing interlocking plate to press down the same as the moving cutter moves. Since the moving cutter cuts the medium at this state, the cut edge of the medium can be excellent in linearity even if it has low rigidity in the outward-surface direction at right angles to the surface thereof. While the moving cutter does not cut the medium, the presser member is retracted to a standby position.
