An ultrasonic cutter cuts edge chamfers of plate-shaped workpieces using a cutter head which forms an axis of rotation and a blade which extends from the cutter head and forms a cutting wedge, terminating in a straight cutting edge, between flank and contact faces determined by the wedge angle. In order to create advantageous structural conditions, the axis of rotation extending on the blade side of the flank face is at a distance from the flank face which is equal to or greater than the distance of the center of mass of the blade from the flank face and the cutting edge, extending in the direction of the axis of rotation, extends at a distance from the axis of rotation which corresponds at most to the blade thickness.

The Present invention provides a cooking device for cutting a foodstuff into a prescribed shape, a cooking method using said device, and a foodstuff. Provided is a cooking device that is provided with a cutting portion and a handle to which the cutting portion is attached, wherein: the cutting portion includes a cutting blade and a guide; the cutting blade includes a wave-shaped portion in which trough portions, which are shaped so as to recede downward in a direction approaching a foodstuff to be cut, and crest portions, which are shaped so as to project upward in the opposite direction to the downward direction, appear alternatively; in the cutting blade, crests, which are the tops of the cutting blade crest portions, and troughs, which are the bottoms of the cutting blade trough portions, appear alternatively; and in the guide, at least a portion of a guide surface, which follows the surface of the foodstuff to be cut, is located between the cutting blade crests and cutting blade troughs in the vertical direction.

A cutting tool for cutting sheets of materials, such as, for example, sheets of building materials. The cutting tool includes a working table with a support surface. The working table includes a slot extending through the support surface. The cutting tool further includes a handle and blade pivotally engaged with respect to the working table between an open position and a closed position. The cutting tool further includes a guide rail that can be connected to the base in a plurality of positions relative to a cutting plane of the blade include a parallel position and a perpendicular position.

A blade (6) for underwater granulation of an extruded polymer, this blade comprising a plate (60) bounded by a contour including a cutting edge contour (61) having a first end (62) and a second end (63), and an outer contour (64) linking the first end (62) and the second end (63) of the cutting edge contour (61),

characterized in that the outer contour (64) comprises at least a first bearing portion (65) and a second bearing portion (66), the first bearing portion (65) and the second bearing portion (66) diverging while extending away from the cutting edge contour (61) and being configured to be received in a dovetail housing (13).

A method of perforating a web includes: rotating a cylinder comprising a longitudinal cylinder axis and at least one shaped anvil disposed on the cylinder; operatively engaging a support with the cylinder, wherein the support is moveable with respect to the cylinder; positioning a blade disposed on the support so as to cooperate in contacting relationship with the anvil, wherein the blade is substantially parallel to the longitudinal cylinder axis, and wherein at least one of the blade and the anvil comprise a plurality of teeth, and wherein adjacent teeth are separated by a recessed portion; and feeding a web between the cylinder and the support while the blade cooperates in contacting relationship with shaped anvil to perforate the web.

A machine for forming packing templates includes a infeed mechanism that can feed multiple feeds of sheet material into the machine without repositioning the infeed mechanism or forming creases or bends in the sheet material. The machine also includes a separation and cutting systems with one or more cutting tables and biased knives that cut the sheet material packaging templates. The machine also includes creasing roller(s) that forms creases in the sheet material. The machine also includes a system for reducing or eliminating the impact of irregularities in the sheet material.

A cutting assembly for use in a hydro-cutting system in which water and food products are conveyed through tubes and the food products are sliced into smaller pieces. The cutting assembly includes multiple disks and U-shaped blades. Legs of the blades are mounted between the substantially parallel disks on opposite sides of the disks, thereby holding the blades in place. A rotationally-driven motor driveshaft extends through the assembly and the assembly is mounted in a tube. When the water and food products are conveyed into the cutting assembly, the rotating assembly slices pieces from the food product, and the pieces are separated from the water for later use or processing. The water can be used in another slicing cycle.

A chopper assembly for cutting filaments in a strand into short lengths, comprising two rolls (1,4) being rotatable in opposite directions and having a pinch where the rolls (1,4) contact each other. At least one of the rolls (1,4) is provided with cutting blades (2,5) at its cylindrical outer surface. Means (15) are present for guiding said strand to said pinch where the filaments of the strand are cut. Both axes of rotation (16,17) of the rolls (1,4) are parallel to the tangential plane through said pinch and make an angle (α) with each other, so that the cutting blades (2,5) move in axial direction with respect to each other in the pinch.

This compact binding device is such that binding operations can be carried out when the main body of the device is held. The binding device (1A) is provided with a cassette storage unit (60A) in which a cassette (8) can be detachably attached, said cassette housing an elongate tape (5) which has a piece (2) adhered thereto and is wound into a roll. The cassette housing unit (60A) is provided at the bottom of the device main body (110A), which comprises a base unit (11A) and a handle unit (12), and the cassette (8) does not protrude rearwards from the handle unit (12) and the base unit (11A).

Some embodiments of the present disclosure relate to a blade. In some embodiments, the blade is configured to produce 50% to 99.9% less residual dust than a comparative blade when the blade is used to cut at least one foam board, where the comparative blade is identical to the blade, except that the comparative blade does not comprise any notches. Methods of using and making the blade and systems that include the blade are also described.
