The food comminution device includes a cutting part (3), a spiral cutting part (6) and a rotary drive (5), wherein food items (4) for comminution can, in order to be comminuted, be selectively pushed through the cutting part (3) or rotated by means of the rotary drive relative to a spiral cutting part (6). The food comminution device further includes an actuating part (1) and a base part (2) which has a cutting part (3), wherein the actuating part (1) is movably connectable to the base part (2) such that food items (4) for comminution can be pushed through the cutting part (3) by means of a movement of the actuating part (1) relative to the base part (2). The actuating part (1) has a rotary drive by means of which a food item (4) for comminution can be rotated relative to a spiral cutting part (6).

The present invention relates to an apparatus and a process for cutting a substrate wherein the apparatus comprises first and second cutting element and wherein the first and second cutting elements are rotatable about the axis of rotation at different circumferential speeds.

Proposed is a pouch cutter for a secondary battery. The pouch cutter includes a bottom knife (20) having a blade and a top knife (30) having a blade disposed to be adjacent to the blade of the bottom knife (20), wherein the blade of the bottom knife (20) and/or the blade of the top knife (30) are formed at an acute angle, the bottom knife (20) and the top knife (30) are cutters having a square cross section, and at least the top knife (30) from among the top knife (30) and the bottom knife (20) has a first top knife blade (35A), a second top knife blade (35B), a third top knife blade (35C), and a fourth top knife blade (35D), which are formed at an acute angle so as to be adjacent to four corners of the top knife.

A solar panel cutting unit according to an embodiment can separate layers of a solar panel from each other at once. The solar panel cutting unit separates thin layers of a solar panel from each other and includes a frame, a panel transporting mechanism that is provided at the frame and lowers the solar panel in a vertical direction such that adhesion lines of the thin layers are arranged downward, a pair of guide roller units that is positioned below the panel transporting mechanism and guides and lowers the solar panel, and a wire cutting mechanism that includes a pair of support rollers and cutting wires which connect the support rollers to each other and extend in the same direction as the adhesion lines such that the wire cutting mechanism separates the thin layers of the solar panel from each other.

The modular cutter assembly for cutting composite material and for use in a composite placement machine wherein the cutter assembly includes a base and a cutting member. The cutting member being removably attachable to the base by a mechanical connection.

A cutting method and apparatus for closures of the “tethered” type are disclosed, in which a spindle that carries a closure is moved to a cutting device with one or more horizontal blades and at least one vertical or oblique blade. During cutting, the spindle rotates and the closure rolls on the cutting device. The spindle, which is fed several times to the cutting device carrying each time a different closure, comprises a portion made of a softer material than the blades so that during cutting the blades penetrate the material of the closure and then sink into the softer portion of the spindle. Feeding the spindle that carries the closure to the cutting device is coordinated with rotation of the spindle so that the vertical or oblique blade, each time that the spindle is fed to the cutting device, always meets the same zone of the softer portion of the spindle.

A saw blade includes a main body having a first surface, a second surface on an opposite side of the main body from the first surface, a proximal edge portion, a distal edge portion, and first and second side portions extending between the proximal and distal edge portions. The proximal edge portion is configured to be coupled to a rotatable hub such that the saw blade is held in a curved shape with the first surface defining an outer radius when the saw blade is coupled to the rotatable hub. The distal edge portion includes a plurality of cutting teeth, and the second surface includes a cutting structure configured such that a radius of an arc swept by the cutting structure when the saw blade is rotated is substantially equal to the outer radius of the first surface.

A knife is described that is arranged for being fitted in a cutting apparatus for obtaining incision lines and notches on a cap made of plastics intended for closing a container, the knife being suitable for making notches and incisions on a side wall of the cap when the cap, by rotating around a rotation axis thereof, is moved along a path for interacting with the knife in an advancement direction, the knife including a plurality of tools arranged in a layered structure, wherein the cutting tools are parallel to a plane and stacked in a direction of a vertical axis orthogonal to the plane, the layered structure including: a first horizontal cutting tool arranged for performing circumferential notches on the side wall at a first height on the vertical axis to determine in use a tamperproof ring and a main body in the cap; a second horizontal cutting tool arranged for performing further circumferential notches on the side wall at a second height on the vertical axis that is different from the first height; and a transverse cutting tool arranged for making at least one transverse notch, where “transverse” means transverse to the plane, to determine in use together with the second horizontal cutting tool and the first horizontal cutting tool a tab portion on the main body, the tab portion being arranged for maintaining the main body overturned with respect to said tamperproof ring once said container is opened, wherein the transverse cutting tool includes at least two transverse cutting edges, each transverse cutting edge extending substantially vertically.

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.
