An ultrasonic knife has a cutting portion formed with at least one cutting edge and a fastening portion. The fastening portion has an external thread for connection to a sonotrode. The cutting portion and the fastening portion are formed in one piece from cemented carbide material. The cemented carbide material includes hard particles that are, at least predominantly, formed by tungsten carbide and a metallic binder. The external thread of the fastening portion has a thread pitch p and is shaped such that the root of the thread turns has a rounded shape with a root radius R of 0.2*p≤R≤0.3*p.

Method for cutting soft metals, comprising the use of a cutting tool capable of being set in motion by ultrasonic vibration. The method is employed for cutting components used in the manufacture of an electrochemical storage device, for example, a lithium battery. These components include the anodes, the cathodes, the solid electrolytes, the current collectors and the separators. The method is also employed in a system for manufacturing and/or characterizing an electrochemical storage device.

The label issuing device, which reels out linerless paper having an adhesive face on one side and cuts the reeled-out linerless paper to issue individual labels, has a cutter part for cutting the reeled-out linerless paper and a detachable container that is detachable from an enclosure of the label issuing device. The detachable container has a reservoir part for reserving a lubricant, and an application part that extends from the reservoir part, receives the lubricant reserved in the reservoir part, and applies the lubricant to a blade body of the cutter part. The reservoir part is filled with an impregnation material that is impregnated with the lubricant to hold (reserve) the lubricant, wherein the impregnation material is coupled to an impregnation material of the application part.

A machine used to convey and cut thin walled wax extrusions. The machine is adjustable and capable of short rapid cuts while maintaining square and consistent finish on the surface of the wax as the knife passes through. The machine may be particularly useful for any wax extrusion requiring a smooth and square cut while remaining capable of running multiple strands in one process to increase production capabilities of a single machine.

A coating removal device removing a coating of an optical fiber along an axial direction of the optical fiber includes a heating portion including a cutting blade making a cut in the coating of the optical fiber, and a heater heating a part of the coating that is closer to a tip thereof than the cutting blade; a main body portion including a control board electrically connected with the heater; a holding portion holding the optical fiber, the holding portion being provided on the opposite side to the heater with the cutting blade being located between the holding portion and the heater; and a slide mechanism allowing the holding portion to slidably move with respect to the heating portion such that the holding portion is distanced away from the heating portion in the axial direction. The main body portion, the heating portion and the holding portion are located in this order in the axial direction, and the heating portion includes a vibration notification portion giving information to an operator by vibrating.

A cutting device for cutting an optical fiber running in a first direction includes a supporting piece having a free end and a fixed end and having resilience, a cutting blade supported by the supporting piece that comes into contact with the optical fiber to make a right angle with the optical fiber at a point of the contact, and a driving device. The driving device is configured to press the supporting piece in a second direction in a plane perpendicular to the first direction, with the second direction not intersecting with the first direction.

The lubrication device delivers a lubricant to the perforating device which provides intermittently spaced cuts to a moving web, also referred to as perforations. The lubrication device includes a retaining member, a plenum, and a comb having a plurality of comb channels. The plenum and the plurality of comb channels are in fluid communication with one another and deliver a lubricant to the perforating device. Lubrication of the perforating device in this manner may improve knife life, perforation quality and web handling.

An ultrasonic cutting machine including a support structure, a positioning device moveable relative to the support structure, a cutting blade connected to the positioning device and a blade cleaning system positioned proximate the support structure, the blade cleaning system including a basin defining an internal volume and an opening into the internal volume, a solvent positioned in the internal volume, a cleaning surface positioned in the internal volume, wherein the cleaning surface is at least partially submerged in the solvent, and a lid positioned over the opening, wherein the lid is automatically displaced from the opening when the cutting blade approximates the basin.

Apparatuses and methods for slicing products, including food products. Such an apparatus has an annular-shaped cutting head equipped with knife assemblies located at a circumference of the cutting head, and interior surfaces each located in a circumferential direction of the cutting head relative to one of the knife assemblies such that each interior surface leads one of the knife assemblies and trails a different one of the knife assemblies. Each knife assembly has a flat knife that extends radially inward to define a gate opening. Each interior surface has continuous flow paths defined therein that extend across at least a majority of the interior surface from adjacent a leading edge thereof through a trailing edge thereof and are fluidically connected to one of the gate openings between the interior surface and the knife that trails the interior surface.
