Abstract: Methods, apparatus, and systems for cutting material used in fused deposition modeling systems are provided, which comprise a ribbon including one or more perforations. Material is passed through at least one perforation and movement of the ribbon cuts the material. A further embodiment comprises a disk including one or more blade structures, each forming at least one cavity. Material is passed through at least one cavity and a rotational movement of the disk cuts the material. A further embodiment comprises a slider-crank mechanism including a slider coupled to a set of parallel rails of a guide shaft. The slider moves along a length of the rails to cut the material. Yet another embodiment comprises one or more rotatable blade structures coupled to at least one rod. The rotation of the blade structures causes the blade structures to intersect and cut extruded material during each rotation.

Abstract: The present invention relates to a bale cutting apparatus comprising attachment means for coupling the apparatus to a prime mover and a cutting means to cut through a bale containing fodder. The apparatus has cutting means that is operable to retain the bale against a stop member and cut through the bale such that the fodder is discharged from the bale and any bale covering materials are retained by the apparatus. The present invention eliminates the need to separately remove any covering materials in which the fodder is wrapped.

Abstract: The problem of penetrating through nets and other objects is solved by cutting the object using a linear cutting assembly having a linear cutter arm that moves in an arc and pivots about an attachment point. The object is cut by a severing action caused by a moveable blade of the linear cutting arm moving back and forth across a stationary blade of the linear cutter arm. An underwater vehicle modified to incorporate an embodiment of the linear cutting assembly can cut a sufficiently large opening in the object to allow the vehicle to pass through.

Abstract: A carpenter's sawing machine that includes a base, an elongated saw support body, and a saw. The saw support body is pivotally attached to the base to change a first cutting angle of the saw. The saw is pivotally mounted in the saw support base to change a second cutting angle of the saw. The sawing machine is therefore capable of serving as a compound miter saw.

Abstract: An improved appliance for slicing food articles, particularly baked goods and bagels in a uniform, quick and safe manner. The appliance includes a food receptacle which is slidably inserted into one end of a main housing and into which a food item such as a bagel is placed. A motorized cutting carriage is pivotally mounted to the main housing and extends a serrated dual-bladed slicing assembly over the food item. When power is applied, the blades of the slicing assembly begin reciprocating, and the entire cutting carriage is pivoted with respect to the main housing in order to move the reciprocating blades of the slicing assembly through the food item. Once the food item is cut, the cutting carriage is returned to its home position, the food receptacle is slidably withdrawn, and the sliced food item is removed and consumed. The appliance requires a minimum of space and facilitates the slicing operation without damage to the bagel.

Abstract: A compound miter saw comprises a base, an arm rotatingly connected thereto about a horizontal plane, and a pair of adjustable vertical saw supporting members on either end thereof. The improvement thereof comprises a plurality of longitudinally aligned rows of projections formed on the support surface of the base. A workpiece can be supported at an elevated angle along the support surface wherein one side thereof rests against a guide plate along one side of the base and an adjoining corner portion is ensconced between a selected pair of adjacent rows. Each pin of adjacent rows of projections provides a unique elevation angle.

Abstract: A method and apparatus for slicing, lifting and carrying round bales or the like. The method for slicing the bale consists of making a radial cut through the length of the bale. The radial cut causes the circumferentially wrapped bale fibers to be cut which causes bale to open up. A partial radial cut, leaving the outer bale fibers uncut, can be made leaving bale substantially in a cylindrical shape to facilitate easy transport with a forklift like carrier. The apparatus consists of a mast assembly mounted to raiseable three point hitch of an agricultural tractor or the like. A pair of parallel forks are directly attached to mast and engage the curved sides of bale so as to lift and support bale for easy transport. A hydraulically activated knife assembly is attached to mast and forks. The knife has serrated teeth which cut through bale when knife reciprocates. A bumper or work guide when attached to the end of forks holds bale during cutting process.

Abstract: A machine for cutting out flat material comprising a support for the flat material, a carriage guided for displacement along the support by at least one guide rail, the carriage bearing a beam extending above the support and pivotable, in relation to the carriage, about an at least approximately vertical, first pivot axis, this beam having at least two arms interconnected by a joint having a second pivot axis parallel to the first pivot axis and the outer arm of said two arms bearing a cutting mechanism pivotable, in relation to the outer beam arm, about a third pivot axis parallel to the first pivot axis and a foot of the cutting mechanism being in contact with the support during operation. In order to simplify the construction of the beam but still ensure that the cutting mechanism always rests perpendicularly on the support, this cutting mechanism is adapted to swivel, in relation to the support, about a tilt axis parallel to the support and rests with its foot on this support.

Abstract: A light-weight and structurally simple system for guiding the saw frame of a mechanical frame saw machine having a crank drive and a stationary machine frame on which the system is pivotally mounted.

Abstract: A hack sawing machine is disclosed, which comprises a base, a case, a shaft rotated by a motor, a saw blade bow guided in a sliding movement in the case, a drum cam which causes the blade to have an active forward stroke and a passive return stroke, a two-armed lever (bracket), eleastic means which, rotating the case, bring the blade back into the cut after the passive stroke and a hydraulic system. This system comprises a hydraulic cylinder, a hydraulic circuit having a hydraulic pump to pump oil to the cylinder. The hydraulic circuit acts to maintain a predetermined pressure of the saw blade bow on the workpiece during the active stroke and camming means cause the bow to be raised during the passive stroke.

Abstract: Large diameter long rolls of soft, spongy resilient material, for example, such as "microfoam" padding and packaging material which are to be cut into narrower sub-rolls are positioned in a support frame having means for restricting the rotational movement of the roll in one direction in the frame. A long knife blade and its reciprocating drive are positioned on the frame and with the knife blade being initially tangentially disposed with respect to the periphery of the roll. The reciprocating drive is positioned for reciprocally driving and incrementally advancing the knife blade inward with the knife blade rotating the roll on the push stroke of the blade while cutting and advancing inward along an arc on the pull stroke of the reciprocating drive.
