| 20120132048 | ELECTRIC SAW DEVICE HAVING TWO SAW BLADES - An electric saw device having two saw blades being arranged for allowing the two saw blades to be driven to rotate in opposite directions. The two saw blades are respectively formed with circular grooves on their inner surfaces at positions corresponding to each other while enabling the centers of the two circular grooves to aligned with the rotation axes of corresponding saw blades. The electric saw device has a plurality of steel balls, each being sandwiched between the two saw blades while insetting into the circular grooves simultaneously, by that the saw blades are separated from each other by a specific interval. Accordingly, when the two saw blades are rotating in opposite direction, each of the steel balls is acting as a roller bearing for maintaining the two saw blades to be properly separated from each other, and thus preventing the two saw blades from overheating and softened by friction. | 05-31-2012 |

| 083500000 | Tool pair comprises contacting overlapped discs | 5 |
| 20080202304 | Rotary cutter for trimming printed products conveyed in an overlapping flow - A rotary cutter for trimming printed products conveyed in an overlapping flow. The rotary cutter including a first knife that rotates and a second knife that rotates counter to the first knife. The second knife is arranged to operate jointly with the first knife. At least one of the knives includes a plurality of blades distributed over a circumference. A conveying device conveys the overlapping flow between the first knife and the second knife. A control unit controls the rotational speed of at least one of the first knife and the second knife. The rotational speed of at least one of the knives is predetermined based on at least one of the speed value for the conveying device or a thickness value of the overlapping flow. | 08-28-2008 |
| 20090019982 | Cutting Tool for Hobbyists - An improved cutting device that is specifically organized to efficiently line up and completely cut planks of lightweight wood and other materials, particularly materials important to RC modelers. More specifically, the invention comprises two rotary blades that are partially overlapped thereby providing for a cutting means while also providing for stability and preventing the lightweight material from moving along other planes (e.g. side-to-side, up-down) at the cutting surface. | 01-22-2009 |
| 20090044675 | Cutting arrangement having a tip-to-tip blade arrangement - A cutting arrangement for longitudinally cutting or dividing material comprising two blades that are disposed across from one another and that during the cutting process cooperate with one another. Each of the blades is embodied as a circular blade having a sharp cutting edge and supported by an adjusting or placement mechanism. During the cutting process the circular blades are positioned by the adjusting or placement mechanisms in such a way that the cutting edges overlap one another to form an overlap zone, the center of which coincides with the middle of the material that is to be cut or divided. | 02-19-2009 |
| 20110126683 | Rotary Sheet Metal Cutter - A rotary sheet metal cutter for cutting sheet metal in various curvatures. The rotary cutter generally includes a base, a first cutting assembly supported by the base and including a first drive assembly and a first circular blade, a second cutting assembly supported by the base and including a second drive assembly and a second circular blade cooperating with the first circular blade. The first circular blade is driven in a first rotational direction and the second circular blade is driven in a second rotational direction opposite the first rotational direction. The first circular blade and the second circular blade each include an overlapping portion along a feed path for cutting a piece of sheet metal engaging the overlapping portions of the first circular blade and the second circular blade. Another circular blade aligned with the first circular blade may also be used. | 06-02-2011 |
| 20140190325 | Moulding for building exterior and machine for cutting same - A machine for cutting eavestrough into two segments. The machine has a guide plate and a pair of cutting wheels. The guide plate has an opening of a shape similar to that of the cross-section of the eavestrough but slightly larger so that as the eavestrough is fed through the opening, it is guided by the guide plate. The cutting wheels are positioned such that after the eavestrough exits from the opening, its bottom wall passes between the wheels where it is cut. | 07-10-2014 |
| 083505000 | Tool pair comprises disc and cylindrical anvil | 2 |
| 20110239840 | CUTTING OBJECT CUTTING DEVICE AND INKJET PAPER FABRICATION DEVICE - A cutting device is provided with a lower blade, an upper blade and a collar. Inkjet paper, in which an ink-receiving layer is formed on paper, is wound around an outer periphery face of the lower blade, and a blade tip is formed at one axial direction end of the lower blade. The upper blade rotates with a blade tip thereof opposing the blade tip of the lower blade in the axial direction, and the upper blade cuts the inkjet paper from the paper side thereof. The collar supports the inkjet paper, which is wound around the collar at a position that is separated from the lower blade in the axial direction. A portion of the collar, including shoulder curve portions at the two axial direction ends thereof, is constituted with PTFE. | 10-06-2011 |
