Machines for cutting products and impellers suitable for use with the machines. The impellers include a lower plate having a central zone and paddles configured with the lower plate outside of the central zone to direct material to the cutting head. At least a first exit slot is located in the lower plate, intersecting the perimeter of the lower plate, and extending through the lower plate to define a passageway to enable foreign debris at the upper surface to exit the impeller through the passageway.

A solar panel disassembling apparatus according to an embodiment of the present disclosure separates a glass plate of a solar panel and a film layer bonded to the glass plate from each other. The solar panel disassembling apparatus includes a supply module that stands and fixes the solar panel such that a bond line between the glass plate and the film layer is exposed upward and downward and that moves the solar panel in a parallel direction parallel to a bonding surface between the glass plate and the film layer, and a wire-shaped cutting blade that is disposed in front of the solar panel in a movement direction of the solar panel to have a distance from the supply module, is disposed in parallel to the bonding surface, and separates the glass plate and the film layer from each other.

A cutter includes a main body, a cog assembly, and a blade. The main body is provided with an anvil. The cog assembly includes a drive shaft and a first and a second cog. The drive shaft is rotatably connected to the main body. The drive shaft has a first end configured to detachably connect which a power tool. The first cog moves synchronously with the drive shaft. The second cog is rotatably connected to the main body and rotates upon rotation of the first cog. The blade is rotatably connected to the main body and connected to the second cog. The blade is rotatable between a deployment position and a cutting position and has a cutting edge. The cutting edge is disposed away from the anvil when the blade is in the deployment position, but is adjacent to the anvil when the blade is in the cutting position.

Provided is a method for manufacturing a sheet for use in a tongue plaque cleaner, capable of reliably cutting loops of thread members provided at a given density, and forming thread members each having a shape with an arc portion sufficient enough to scrape off tongue plaque, through steps that are simple, low-cost and suitable for mass production. A method for manufacturing a sheet 1 for use in a tongue plaque cleaner for scraping off tongue plaque, includes: a step of heating a sheet material having multiple looped thread members 2 protruding from one surface of the sheet material, at a temperature below the melting point of the thread members 2; and a step of forming first thread members 3, 8 and second thread members 4, 9 by cutting loops of the thread members 2 heated.

In one embodiment, a method includes causing a robotic limb to intercouple with a handle of a knife. The knife comprising a handle at a proximal end where the handle is configured to intercouple with the robotic limb, a bade connected to the handle, and an indentation at a distal end where the indentation is configured to intercouple with a bar of the cutting surface, and where the blade is rotatable around a first axis while intercoupled with the bar. The method includes causing the indentation of the knife to be intercoupled with the bar of a cutting board. The cutting board comprising the cutting surface and the bar affixed to the cutting surface. The method includes adjusting, by the robotic limb the position of the knife along the bar to along with an object on the cutting surface and rotating the knife to cut the object.

A cartridge adapted to secure reciprocating bread slicer blades including a rectangular frame having a planar surface, the frame having a plurality of pairs of opposed holders, each pair of the opposed holders adapted to releasably secure opposed ends of a corresponding bread slicer blade. The frame is adapted to secure a plurality of aligned bread slicer blades defining a plane offset from the frame planar surface. The frame is adapted to selectively maintain each of the plurality of aligned bread slicer blades in tension.

A tension knife includes an elongate knife body with a thin, flat profile. The tension knife defines first and second mounting points at opposing ends of the knife body. The knife body has a characteristic width across a length of the knife body between the first and second mounting points. The characteristic width of the knife body defines a centerline between a leading edge of the knife body and a trailing edge of the knife body. One or more of the first and second mounting points has a focus between the centerline of the knife body and the leading edge. A frame can be configured to support and tension the tension knife to form a tension knife assembly. Clamp blocks can be used to mount the tension knife to the frame at the first and second mounting points, where one or more of the clamp blocks is configured to rotate with respect to the frame to tension the leading edge of the tension knife.

A method for disassembling a battery housing of a high-voltage battery system, in particular of a vehicle, in which housing parts of the battery housing are in material connection with each other along joining flanges, wherein for disassembling the battery housing a disassembly tool is inserted into a joining gap between the joining flanges to loosen the material connection.

A method includes forming one or more plug holes into a tool surface of a body. The one or more plug holes are partially formed around a landing surface portion of a plug in the body. The method also includes engaging a tool with the landing surface portion of the plug in the body, and using the tool to cut away the plug from the body and at least part of the body to form a tooled void into the body.

A method where a propeller is set into locomotion relative to a medium at least partially surrounding the propeller. An actuator induces a rotation of the propeller relative to the medium and about a rotational axis of the propeller, and the propeller converts its rotational movement into locomotion relative to the medium. The aspect ratio of at least one cross-section of the propeller is three or more. Also a helical or modifiedly helical propeller for converting rotational movement of the propeller into locomotion of the propeller relative to a medium at least partially surrounding the propeller, where the aspect ratio of at least one cross section of the propeller is three or more. And a method of producing a propeller, including the step of providing a plate extending along the helical axis, where the aspect ratio of at least one cross section of the plate is three or more.
