A blade driving apparatus configured to drive a blade of a cutting device to cut a web and includes an anvil and a slide assembly. The slide assembly includes a slide rail and a slide block that are slidably connected to each other. The slide block is connected to the anvil, and the slide block and the anvil move back and forth relative to the slide rail along a travel direction of the web. At least one of the slide rail or the slide block is made of a non-metallic material.

A system comprising a mandrel, a winding device for helically winding strips around the mandrel to form a base tube moving away from the mandrel at a tube speed, a strip suppling device for supplying the strips to the winding device, and a cutting device for cutting the base tube at a predetermined length to form the lengths of tube while the base tube is moving in a tube direction at the tube speed, and a method.

During an assembly process for an aircraft, segments of the fuselage are fabricated separately prior to joining the segments together to form the complete fuselage. In order to ensure that abutting ends of the segments mate together correctly, a machining process is performed along the edges of the segments at their ends. One embodiment comprises a trim-tool assembly for machining proximate to an edge of a workpiece. The trim-tool assembly includes an indexing cart configured to mount to a track secured to a surface of the workpiece, where a setting on the indexing cart varies a distance between a centerline of the track and the edge of the workpiece. The trim-tool assembly further includes a tool cart configured to mount to and translate along the track, where the tool cart includes a process tool that performs a machining process on the workpiece at a fixed distance from the centerline of the track.

Embodiments are directed to an automated cutting tool that is configured to cut open nonuniform enclosures, such as cases containing electronic components. An example system comprises a multi-speed motor that is coupled to a cradle. The multi-speed motor rotates the cradle at a selected speed, and the cradle adapted to hold a case. A cutting head is positioned adjacent to the cradle and is configured to maintain contact with the case during rotation of the multi-speed motor. The multi-speed motor is configured to operate at a first speed when first segments of the case are in contact with the cutting head and to operate at a second speed when second segments of the case are in contact with the cutting head.

A method cuts an extruded pipe to length using a separating device. The separating device includes a separator rotating about an extrusion axis of the extruded pipe, the separator being rotatably mounted in the separating device, and cutting tools being arranged on the separator. The cutting tools are configured to carry out the separation. The method includes transferring energy to move the cutting tools. The energy is transferred from a stationary outer region of the separating device to a movable inner region of the separating device. The energy is transferred continuously or cyclically and the transferred energy is buffered in an energy storage device. The energy is transferred inductively or capacitively. A discharge time of the energy storage device is between 2% and 25% of a total separation cycle.

A separating device cuts an extruded pipe to length. The separating device has a separator that is rotatably mounted and rotates about an extrusion axis. Cutting tools are arranged on the separator and move in accordance with received energy. A rotating receiver is in the separator. An electromechanical drive is configured to move a carrier that supports a cutting tool. The electromechanical drive and the carrier are on the rotating receiver. An energy conductor is connected to a moving part of the rotating receiver, the energy conductor being coupled to an energy supplier arranged on the rotating receiver. The energy and control commands are transmitted to the electromechanical drive via the energy conductor and the energy supplier. The electromechanical drive, the carrier, or the cutting tool yield to a force counter to a separating force that is greater than a required separating force for cutting the extruded pipe.

A cutting unit for thermoplastic pipes includes a ring rotating about an axis and in which a pipe is progressively moved in a sliding fashion such that a longitudinal axis of the pipe coincides with said axis of rotation and a cutting arm mounted on the ring. A distance measurement sensor located on the ring is configured for acquiring, during rotation of the ring, values representing a radial distance between the measurement sensor and an outer surface of the pipe. The distance is measured on a measurement plane transversal to the axis of rotation. The cutting unit also includes a processing and control unit operatively connected to the measurement sensor and configured for receiving the values measured and for calculating, on the basis of the values, at least one parameter representing a peripheral profile of the pipe on the measurement plane.

The device for cutting individual tubes from a continuous tubular product moving in translation in an uninterrupted manner and formed by a production machine, comprises at least one frame that is stationary relative to the machine, an assembly that is movable in translation relative to the frame and supports a cutting head moved in reciprocating linear translation and in rotation, a first mechanism for moving said cutting head in reciprocating translation, a second mechanism for rotating said cutting head and a third mechanism for actuating the start and the end of the cutting operation, in which said mechanisms are stationary relative to the frame of the device.
