Abstract: A sheet cutter for making business cards is composed of an upper cover, a seat mounted beneath the upper cover, a transversal blade assembly and a longitudinal blade assembly. By using the transversal blade, a sheet printed with multiple business card details in rows and columns can be conveniently cut into individual business cards along the longitudinal and transversal directions.

Abstract: An improved chop saw may include a base assembly, a blade assembly including a blade having a center and a motor for driving the blade, an arm pivotally attached to the base assembly and carrying the blade assembly, the blade assembly being movable between a lower position for engaging and cutting a workpiece disposed on the base, and an upper position not engaging the workpiece. The chop saw further includes a vise for holding the workpiece in place, the vise including a vise screw, a latch support supporting the vise screw, and a vise jaw disposed at the end of the vise screw. Preferably, the maximum distance between the vise jaw and the latch support is about equal or shorter than the distance between the blade center and the latch support, when the blade assembly is at the lower position. Further the chop saw includes a substantially horizontal handle connected to the blade assembly.

Abstract: A cut alignment device for a rotary saw having a motor which spins a cutting unit which includes a rotary shaft driven by the motor, a circular blade having a central aperture through which the shaft fits, and a blade mounting device for holding the blade on the shaft, the cut alignment device including: a battery power source carried by the cutting unit; and a beam light source, operatively connected to this power source, and carried by the cutting unit; wherein the light source projects a light beam at a shallow angle from the cutting unit directed to intersect the plane of the rotary cutting tool or saw blade, to assist the operator in cutting accurately.

Abstract: An apparatus for manufacturing wearing articles, comprises a supplier (1) for supplying a continuous body (W) having the ability to absorb a liquid; a cutter (2) for cutting the continuous body (W) at a length in the flow direction shorter than the width of the continuous body (W); and a drum (3) for changing the orientation of the cut pieces (N) of the continuous body (W) so that the cut pieces (N) are elongate in the flow direction.

Abstract: A laser emitter projects a planer light beam to form an optical guideline on a work piece extending in a cutting direction of saw blade. The laser emitter is arranged behind, in the cutting direction, a tangential line of the circumference of the saw blade at an intersection of a bottom surface of the base and the circumference at a front side of the base in the cutting direction. The laser emitter forms the optical guideline behind the intersection in the cutting direction. The laser emitter is supported in respect of the saw blade slidingly in a direction defined by a rotation axis of the saw blade. The saw cover may have a window to transmit the laser beam toward the cutting point. A shutter selectively shutting the window may be provided.

Abstract: A cutting apparatus includes a first annular member having a center eccentric from an axis of a rotating shaft and fixed to the rotating shaft. The cutting apparatus further includes a bearing with its inner race fixed to the first annular member, a disk cutter fixed relative to an outer race of the bearing, and a balancer fixed to the rotating shaft in a state being eccentric in the direction opposite to the eccentric direction of the first annular member.

Abstract: An artificial firelog and firestarter chip producing apparatus comprising a cutting assembly, a compression conveyor auger assembly and a die. The apparatus converts standard waxed corrugated cardboard boxes into artificial firelogs by first slicing cardboard sheets into cardboard strips, then chopping the cardboard strips into cardboard segments in the cutting assembly. The cardboard segments are horizontally disposed between the rifling and compressed in the compression conveyor auger assembly and extruded in the die to form generally horizontally disposed, circular, longitudinally-shaped sections of a firelog. Firestarter chips are fabricated by the cutting assembly, which slices waxed cardboard sheets in conjunction with paper sheets into waxed cardboard and paper strips, then chopping the waxed cardboard strips into waxed cardboard segments and the paper strips into paper segments and waxed cardboard segments mix.

Abstract: A laminated nonwoven fabric comprising a first web having a network structure having laterally extending ribbons and nodes interconnecting longitudinally adjacent ribbons, and a second web laminated to the first web. The first web is fabricated such that one node is laterally shifted from another longitudinally adjacent node so that the nodes are uniformly distributed in the first web. Preferably, the nodes are arranged in a regular pattern and on a line extending oblique to the longitudinal direction of the first web.

Abstract: An improved ring saw having a disk-shaped saw body with a cutting ring mounted to rotate about the saw body. The cutting ring has an inwardly directed flange that fits within a slot in the peripheral edge of the saw body. Cutting teeth are mounted in the ring. Drive means mounted on the saw body rotate the cutting ring about the saw body to have the saw cut into a tree as the saw body is moved toward the tree.

Abstract: The invention is a honeycomb core cutting tool wherein a primary cutter is used to cut the core to shape and secondary cutters are used to immediately shred that portion of the core being removed. The primary cutter is typically a commercially available circular saw blade modified by the machining of a plurality of peripherally located, radially inward directed slots dividing the primary cutter into segments which can be formed into a concave shape. A retainer threadably engages the end of the shaft and is used to force the primary cutter against a concave surface of a flange mounted to the shank of the tool, causing the primary cutter to deform into the concave shape. Mounted behind the flange and primary cutter are two "slot" cutters for shredding the portion of the core being removed.

Abstract: A sawing method involving in one direction continuously driven saw blades (1, 2) or saw wheels, according to which two saw blades (1, 2) or saw wheels are arranged in an adjacent position to each other, with associated saw teeths extending in an opposed relationship to each other. The saw blades (1, 2) or the saw wheels are thereafter caused to perform a continuous movement in opposite directions to each other in the operative direction for each saw blade (1, 2) or saw wheel, whereby same in a common and co-acting operation take up a saw cut in a workpiece. In order to maintain the saw teeths of the saw blades (1, 2) or the saw wheels separated from each other during a sawing operation, a pneumatical or hydraulical medium under pressure is advantageously supplied against the adjacently located surfaces of the saw blades (1, 2) or the saw wheels during the sawing operation.

Abstract: A ring having a frustoconical inner periphery for beveling the end of a conduit is mounted on an upright side surface of the circular saw blade of a portable cutoff saw concentric with the axis of rotation of the blade.

Abstract: A tree felling head which includes a frame having a grapple mounted thereon with a grapple jaw which may be selectively opened and closed to respectively receive and grasp a standing tree and power means to selectively open and close the grapple; and a severing device mounted on said frame below said grapple for severing a standing tree. The severing device is a rim driven planar circular saw mounted around a peripheral portion thereof on an arm pivotally attached to the frame for movement in a plane transverse to the length of the standing tree, and included is a second power means for effecting rotation of said severing device.
