A cutting unit (10) for industrial sectors, especially suitable for cutting of flexible or semi-rigid materials such as paper and cardboard, non-woven fabric, spunbond, spunlace and the like into strips of various widths, intended for example for the manufacture of hygienic products such as nappies, sanitary towels, face masks, as well as tissue, tape, packaging and cardboard cores, comprising a supporting structure or casing (12) paired with a flange (14) for supporting the cutting tool (16) consisting of a ring. That said motor is of the torque type in which the rotor (18) and the stator (20) are housed in a seat made along the front face of the casing (12) which is also provided with a housing (28) inside which the control drive (30) of said motor is positioned.

A material cutting device includes a rotatably mounted tool holder configured to carry a cutting tool and a drive for rotating the tool holder. The drive includes an electric motor with a rotor and a stator. The axis of rotation of the rotor of the electric motor and the axis of rotation of the tool holder are arranged coaxially. The stator encloses the rotor over an angle of less than 360 degrees.

A hand-held knockout punch driver includes a housing, a motor positioned within the housing, a head unit removably coupled to the housing, the head unit including a body, an input member movable relative to the body, and a draw rod to which at least one of a punch or a die is attachable. The draw rod is configured to move axially relative to the body in response to movement of the input member relative to the body. A quick-release mechanism removably couples the body to the housing and includes radially inward-extending locking members on one of the housing or the head unit and a plurality of radially outward-extending locking members on the other of the housing or the head unit engageable with the radially inward-extending locking members to lock the head unit to the housing.

An example system includes a cutting tool and a device configured to remotely control the cutting tool. The device is configured to establish a wireless communication with the cutting tool, and the cutting tool is configured to send a first signal to the device indicating that the cutting tool is enabled to be operated remotely responsive to the cutting tool receiving information indicating that a trigger is locked in an “on” state and a remote switch is in a first position. The device is configured to send a second signal to the cutting tool indicating a request to cause the cutting tool to perform a cutting operation responsive to receiving information indicative of actuation of at least one button of a user interface of the device.

A printing apparatus includes a cutter unit that includes a first blade that moves in a first direction from a standby position to a cutting position to cut a printing medium and a drive pin that moves integrally with the first blade, a drive cam which has a cylindrical shape and on a side surface of which a guide groove engaged with the drive pin is provided, and a driving motor that rotates the drive cam, in which, when the drive cam rotates, the guide groove guides, via the drive pin, the first blade in the first direction from the standby position to the cutting position.

A device incorporated into a waterjet cutting machine provided with at least one receiving tank and a movable nozzle, the device being capable of sensing a high-pressure waterjet coming out of the nozzle and including a movable receptacle arranged inside the receiving tank in line with the nozzle, the lower portion of the receptacle being connected to a flexible pipe connected to the bottom of the receiving tank, and —a drive for supporting and moving at least part of the receptacle including the pipe assembly, the drive including a driving member rigidly connected to the nozzle, and a driven member attached to the receptacle, the driving member and the driven member not being mechanically connected.

A slicing machine cuts slices of cutting material. The slicing machine has: a machine housing holding a motor and circular blade driven by the motor; a product feed, which feeds the cutting material to the circular blade; a stop plate; and a slidably arranged carriage, which feeds the cutting material to the blade. The blade is mounted directly on a bearing shaft arranged in the drive motor for the circular blade. The drive motor includes at a stator and rotor, which is detachable from the stator. The stator is in the machine housing. The machine housing has an insertion opening where, in the assembled state, the stator is arranged and through which the rotor is at least partially inserted into the stator. The slicing machine has an attachment device comprising at least one fastener that is configured to fasten the rotor and the stator to the machine housing.

A bundle breaker has upstream and downstream breaking supports each having an input end and an output end. A first platen is located above the upstream breaking support, and a second platen is located above the downstream breaking support, and each platen has an actuator for moving the respective platen toward and away from the breaking supports to selectively clamp a log between the platens and the breaking supports. A third actuator is configured to apply a shifting force to the downstream breaking support to shift the input end of the downstream breaking support relative to the output end of the upstream breaking support from a first position toward a second position to break the second portion of the log from the first portion of the log. The first actuator and/or the second actuator and/or the third actuator includes at least one servo motor.

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.

A spatula edge trimming apparatus for re-edging a spatula includes a base housing with the front side having a spatula receptacle slot extending through to the cavity. The bottom side has a drop aperture extending through to the cavity. The spatula receptacle slot is configured to receive a spatula. A cutter is coupled to the base housing within the cavity and is configured to cut an edge of the spatula. A drive is coupled to the top side of the base housing and is in operational communication with the cutter. A plurality of controls is coupled to the base housing and is in operational communication with the drive. A power source is coupled to the housing. The power source is in operational communication with, and provides power to, each of the drive and the plurality of controls.
