Disclosed are a cutter assembly and a fruit and vegetable cutter using the cutter assembly. The cutter assembly includes a rotating shaft assembly, a forward-rotating blade and a counter-rotating blade. The rotating shaft assembly has a first mandrel and a first outer shaft. The end of the first mandrel and the end of the first outer shaft are each provided with a first transmission part coupled to a drive device; the blades are respectively arranged in the shaft assembly and perpendicular to the rotating shaft assembly; one blade is coupled to the first mandrel, and the other is coupled with the first outer shaft, so that the blades can be driven by the rotating shaft assembly to rotate in two opposite directions at the same time. The fruit and vegetable cutter includes a fruit and vegetable cavity, the cutter assembly and a driving device for driving the cutter assembly.

A cap for a container is formed so that the cap has a top plate and a circular sidewall. Two opposite sides of the circular sidewall circularly connect to each other, one periphery of the circular sidewall connecting to one surface of the top plate forming a closed end, and another periphery of the circular sidewall at an opposite side of the closed end forms an opened end. Incisions are in the circular sidewall. The incisions form a ring member located at the opened end of the cap separated from a main body of the cap by a first incision and a second incision between the opened end of the main body and the ring member.

Knife assemblies having primary and secondary blades and at least one tab blade. The primary and secondary blades each have a corrugated shape as a result of defining a wave pattern that defines peaks and valleys. The primary and secondary blades each further having upper and lower surfaces, leading and trailing edges, and a depth defined by and between the leading and trailing edges. The upper surface of the primary blade and the lower surface of the secondary blade are complementary so that the secondary blade and the peaks and valleys thereof are able to nest on the primary blade and the peaks and valleys thereof. The secondary blade has at least one tab blade that projects from one of its peaks and is defined by a cut in the peak to form a tab that is bent so that the tab projects from the peak.

A cutting tool for truncating elongated structural members has a frame with a pair of parallel siderails connected at a first end by a support plate and at a second end by a removable end gate, the frame having an open center adapted to receive the structural member therethrough. The truncating is performed by a fixed penetrating cutting edge on an end gate and a driven penetrating blade slidably disposed within the frame to advance towards the end gate. The end gate has two integral penetrating cutting edges pointing in opposite directions. The driven penetrating blade and the fixed penetrating cutting edge may have concave cutting edges relative to one another and configured to be adjacent to one another along the travel of the driven penetrating blade. Alternately, an end gate second cutting edge may be directed to the opening within the frame and have a piercing V-shaped cutting edge.

Impeller for a centrifugal cutting apparatus, provided for being coaxially mounted within an annular-shaped cutting head and to be rotated inside the cutting head about a rotational axis in a rotational direction, the impeller comprising: a base plate, an annular cover plate and a plurality of circumferentially spaced paddles mounted between the base and cover plates. The paddles are oriented such that they have a first impelling surface directed towards the rotational direction and the circumference of the impeller, so as to drive the product that is admitted into the impeller forwards and outwards towards cutting elements mounted on the cutting head. The paddles have peripheral parts located at or near the circumference of the impeller. The peripheral parts of the paddle elements are provided with replaceable, removably mounted wear parts which form a second impelling surface on the respective paddle.

A chopping machine includes a driving unit, a cutting unit, and a conveying unit. The cutting unit has a blade shaft and an immovable blade seat. The blade shaft has a plurality of movable blades. One side of the immovable blade seat is connected with an immovable blade. The conveying unit has a feeding member. Thereby, by putting a material into the feeding member, the driving unit drives the cutting unit and links the conveying unit to run. The material is chopped by the movable blades and the immovable blade, so as to improve the safety in use and reduce the situation that the material is jammed or nipped in the feeding process, and the purpose of labor-saving and fast operation is achieved.

The present disclosure is directed to a process and an apparatus for cutting a continuous rubber-covered belt in a process for building tyres for vehicle wheels, wherein the apparatus comprises a cutting group, in turn comprising: a knife formed by a first half-part and a second half-part and movable along a cutting direction that is tilted with respect to a supply direction of a rubber-covered belt placed beneath the knife. The process comprises: lifting a lifting element placed below the continuous rubber-covered belt and at the cutting zone, until a portion of rubber-covered belt is lifted, and lowering the single first-half part of the knife, making it slide with respect to the second half-part.

A device for manufacturing a chopped fiber bundle includes a cutter roll provided with one or more disk blades on a circumference of a roll core having a center axis coinciding with a rotation axis of the roll core and a nip roll provided in parallel with the rotation axis of the roll core, to feed a reinforcing fiber yarn to be continuously cut between the nip roll and the cutter roll, further including a rotary drive mechanism that rotates the cutter roll and at least one of: a reciprocating drive mechanism that reciprocates the cutter roll along the rotation axis of the roll core; and a traverse guide that traverses the reinforcing fiber yarn along the rotation axis of the roll core.
