Impeller for a centrifugal food cutting apparatus, comprising a base plate and at least one set of paddle parts mounted on the base plate and provided for imparting centrifugal force to food products to be cut. Each set comprises inner and outer paddle parts defining at least a first stage and a second, cutting stage, the inner and outer paddle parts being offset from each other in radial and angular direction of the impeller, such that a safe compartment is defined for food product which is in the second stage.

A pruning system includes a cutting head comprising upper and lower cutting rings positioned along a bottom portion of one or more tubes. At least one cutting ring is adapted to rotate in a circular motion, while the other cutting ring may be adapted to remain stationary. A vacuum may be applied to suction target plant material, and the cutting head may be lowered toward the target plant material. As adjacent blades from the upper and lower cutting rings are separated in an open position, plant material may be collected in the opening defined by the adjacent blades. As the blades converge, the opening may close, and plant material collected in the opening may be severed from the plant. System variables, may be adjusted to accommodate different types of plant material. The pruning system may be used with a vision system to remove materials from plant beds in a field.

A shearing device (1) having a blade (2) with at least one blade cutting edge (5) which is helically coiled, and rotatable, about an axis of rotation (R) of the blade (2). The blade cutting edge (5) is assigned a counterpart blade cutting edge (4) of a counterpart blade (3). The shearing movements, by which for example bristle filaments (7) of brushes (8) for machining can be cut to length, are generated by relative rotational movement of the at least one helically coiled blade cutting edge (5) with respect to the preferably static counterpart blade cutting edge (4) of the counterpart blade (3). Since the blade (2) and the counterpart blade (3) can keep their spacing to one another constant during operation, there is a relatively low risk of injury during the use thereof.

A cutting apparatus for hair or fiber protruding from a surface includes a roller, a number of cutting features disposed at an outer peripheral surface of the roller, wherein the number of cutting features is adapted for cutting the hair or fiber when the roller rotates in contact with the filamentous surface or is moved while in contact with the filamentous surface.

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 modular unit configured for mounting to a cutting head of a slicing machine and for securing a knife to the cutting head, and slicing machines equipped with one or more of such modular units. The modular unit includes mounting blocks adapted to be spaced apart in an axial direction of the cutting head, and a clamping assembly assembled with the mounting blocks so as to extend between the mounting blocks. The clamping assembly is configured to secure a knife to the cutting head, and at least portions of the clamping assembly may be removable from the cutting head by disassembling the clamping assembly from the mounting blocks without removing the mounting blocks from the cutting head.

Cutting head assembly for a centrifugal cutting apparatus, comprising a plurality of drum stations, at least one of which is a cutting station, provided for together forming a drum, and fixing parts provided for assembling and holding the drum stations together. The drum stations have overlapping parts with each time at least one receiving part for receiving one of the fixing parts, such that in assembled condition the adjacent drum stations are each time fixed to each other by means of at least one of the fixing parts at the overlapping parts of the adjacent drum stations.
