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.

Abstract: The rotary cutting blade is mounted on a cutting machine which dispenses and cuts sheet material. The cutting machine includes a frame for supporting a cutting table top and a dispenser for supporting a roll of floor covering material. The rotary disk shaped cutting blade is mounted on a support block the frame below the table top for movement along a slot in the cutting table. A cable or chain driven rotary drive drives the block back and forth and at the same time provides the rotary motion to the cutting disk in a direction such that a leading edge of the disk moves upwardly relative to the floor covering material as it cuts. The chain passes over a sprocket on the block which carries a clutch so that the clutch slips when the block reaches one end of the slot and allows the chain to continue driving the rotary blade. A rotary sharpening disk is mounted at one end of the slot and is driven by the chain so as to rotate against the blade in a sharpening action while the block remains stationary.

Abstract: A sheet material primarily fabric is cut by providing an anvil having an substantially cylindrical wire thereon defining a cutting line lying along the anvil and supported thereby, by draping the fabric over the anvil and by running along the wire of the anvil the peripheral surface of a roller so as to apply pressure between the roller surface and the wire. The fabric is thus compressed between the roller surface and the wire in a pinching action which causes the wire to engage into and effect cutting of the fabric along the cutting line. The roller is mounted on a carriage running along the anvil and is spring biased onto the wire.

Abstract: A slider includes a rotary blade holding case and a guide member. A rotary blade bearing portion is provided on the rotary blade holding case. A shaft extends through a rotary blade while being clamped with a bearing member and a safety plate. After the shaft is coupled with the bearing portion, the guide member is coupled with the rotary blade holding case.

Abstract: The present invention relates to a sharpening device for sharpening a wear edge of a rubber, plastic or polyurethane blade, such as a synthetic squeegee blade used in silk screening printing, comprising a housing with a base and an upper surface having a longitudinal clamp for clamping the blade during the sharpening operation. The sharpening device further comprises a cutting blade or knife which is removably held by a moveable carriage, both of which are located within a housing. The carriage is mounted on a block assembly and, preferably, carries a removable cutter holder. In operation, the carriage travels along the path of the wear edge of the squence blade, and the cutting blade or knife acts to cut off the wear edge of the blade and simultaniously treate a new edge. The cutting blade is mounted in an inclined position, with respect to the horizontal length of the wear edge, so that the upper beveled surface of the cutting blade is substantially parallel to the horizontal plane of the wear edge.

Abstract: A cutting mechanism having a movable carriage and two cutters. Each cutter has an anvil that opposes a blade, and one of these is a roller that rolls against the other for progressively biasing material against the blades, producing cuts through the material. The rollers are rotatably mounted to the carriage, which is mounted to a lead screw that controls the position of the carriage. As the carriage moves across the material, the rollers roll, and the material is cut. The space between the anvil and the blade of at least one of the cutters can be varied to disengage that cutter so that the rolling of the roller will not cut the material. The engagement and disengagement of the cutter is dependent on the position of the carriage.

A blade holder assembly has a outer shell slidably attached to the guide rail, a shaft rotatably attached to the shell, a circular blade attached to the shell and adjacent a lateral edge of the base, and a gear attached to the shaft. As the blade holder assembly is slid on the guide rail the gear engages with the gear track and rotates the shaft and circular blade to cut sheet material inserted between the pressure pad and base.

Abstract: This is a cutter assembly for linerless strip media having an uncovered adhesive backing. There is a cutter mounted for transverse movement across the media and a backing bar with at least two cutting edges. The backing bar can be rotated to place one of the cutting edges in position to cooperate with the cutter to cut the media. The backing bar is rotatable about a transverse axis simultaneously with feed movement of the media at a rotational speed equal to the feed speed of the media. This causes the media to ride up on a pointed portion of a cutting edge without dragging across the cutting edge as the cutting edge moves into a use position in which the media is supported by a support surface of the cutting edge. A cleaning station cleans the previously used cutting edge as the bar is rotated. Rotating and fixed cutters can be used. The cutter is replaceable and can be supplied in combination with an associated media for which it is designed.

A blade assembly includes a blade secured to a blade holder. The blade assembly is received in a cavity formed in the carrier such that a cutting edge of the blade extends below the plate and is received within a channel formed in a cutting region of the base when the plate is disposed over the cutting region. A paper is cut by translation of the carrier along the slot of the plate.

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.
