A packaging unit for producing sealed packages from a tube fed along a first direction and comprising one pair of jaws, which grip the tube along transverse sections, defining respective second directions crosswise to the first direction; sealing means, which seal transverse sections to form sealed packages; separating means for separating packages from the tube along transverse sections and comprising one knife movably supported by one jaw; driving means moving the knife with respect to the jaw along a plane crosswise to the first direction and between a resting position, in which a cutting edge of the knife is spaced from the tube and is aligned with the respective second direction defined by the transverse section to be cut, and an operating position, in which the knife has completely cut the tube at the transverse section; driving means move the cutting edge obliquely with respect to the second direction when said driving means move the knife from the resting position to the operating position; cutting edge contacts the transverse section along a cutting surface parallel to the second direction and increasing as the knife moves from the resting position to the operating position.

A helicoidal blade system is presented having an armature to facilitate bending of metal stock to form helicoidal blades. In one or more embodiments, the armature has an exterior surface that is generally conical in shape and includes a guide structure and an engagement track. The helicoidal blade system also includes drive coupler and motor that are operably coupled together. The drive coupler is configured to engage the engagement track of the conical armature and rotate the conical armature when the motor is operated. A blade metal feed apparatus is configured to feed the metal stock into the helical shaped guide structure as the conical armature is rotated. As the conical armature is rotated, the metal stock is bent around the armature within the helical shaped guide structure to form one or more helicoidal blades.

A cutting disc configured to chop food products by rotating about an axis. There are cutting elements which are located on a first side of the cutting disc and which can chop food products by rotating the cutting disc in a first direction of rotation and which are arranged one behind the other when viewed in the first direction of rotation. The cutting elements arranged one behind the other are different.

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.

A groove engraving device and a groove engraving method are provided. The groove engraving device includes: a processing chamber for containing a piece to be processed, a cutter for groove engraving on the piece to be processed, a clamping mechanism for clamping the piece to be processed, a driving mechanism for driving the clamping mechanism to rotate, and a temperature controlling device for controlling a temperature inside the processing chamber to be within a preset temperature range. The clamping mechanism and the cutter are disposed inside the processing chamber, and the clamping mechanism is rotatable with respect to the processing chamber. The temperature controlling device is disposed inside the processing chamber. The groove engraving device can improve the processing efficiency and quality of the groove engraving on the piece to be processed.

A method for disassembling a battery housing of a high-voltage battery system, in particular of a vehicle, in which housing parts of the battery housing are in material connection with each other along joining flanges, wherein for disassembling the battery housing a disassembly tool is inserted into a joining gap between the joining flanges to loosen the material connection.

A vegetable knife includes a pulverizing coring pin for pulverizing a core of a vegetable, where the pulverizing coring pin can be a generally cylindrical tube. The pulverizing coring pin can define one or more pulverizing tubes that extend from a first end of the pulverizing coring pin to a second end of the pulverizing coring pin opposite the first end. The vegetable knife also includes at least one vegetable shaping blade that extends radially outwardly from the pulverizing coring pin, where the at least one vegetable shaping blade supports the pulverizing coring pin at a location generally central with respect to the vegetable knife. The vegetable knife may also include an outer flange for coupling the vegetable knife to a rotatable cutting assembly. The vegetable shaping blade can be connected between the outer flange and the pulverizing coring pin for supporting the pulverizing coring pin.

A processing apparatus includes an articulated robot having an arm distal-end portion to which a processing tool configured with a cutting edge portion and a profiling portion and a shape measurement unit are attached, and a processor. The processor, in a workpiece set state, recognizes, by measuring a shape of the workpiece using the shape measurement unit, a tilt of a profiled surface portion of the workpiece and a position of a process portion of the workpiece to generate processing-target-portion information based on the position of the process portion, generates processing-point information indicating a processing point, moves the arm distal-end portion to the processing point based on the processing-point information, controls an orientation of the processing tool in accordance with the tilt of the profiled surface portion of the workpiece to perform the specified processing on the workpiece using the processing tool.
