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.

An apparatus for mechanically splitting materials has a body with a cutting element arranged relative thereto. The cutting element has at least one cutting surface oriented vertically. The splitting apparatus has the cutting element applying an upward pressure against the material which is split when a separate downward force is applied to the material. The body of the splitting apparatus also has a safety element to protect the user from the cutting element; an elongate supporting element to distance the safety element from either or both the cutting element and a surface on which the splitting apparatus is used; a stabilizing element to stabilize the splitting apparatus relative to a surface on which the splitting apparatus is used; and optionally a deflecting element to deflect split materials away from the cutting element and container element to contain therewithin split materials produced during the splitting.

A tool for patterning an overlay for placement about a projection structure extending from a mount surface may be temporarily positioned for patterning the overlay in situ. The tool may be configured for engagement with the projection structure, and include a cutting edge that is arranged into a pattern emulating a perimeter of the projection structure. Application of the overlay against the cutting edge of the tool cuts a relief portion from the overlay in situ to obtain an opening having a boundary that is shaped to closely accommodate the projection structure perimeter. The tool is then removed and the overlay applied against the mount surface in surrounding relationship to the projection structure extending from the mount surface.

A cutting device includes: a frame; a fixed blade including a first blade edge portion extending in an extending direction; a movable blade movable in a moving direction; a driving mechanism; and a pressing member. The movable blade includes: a second blade edge portion; and a contacting portion. The second blade edge portion has a valley-like shape such that a center portion in the extending direction thereof is closer to the contacting portion than end portions in the extending direction thereof are to the contacting portion. The second blade edge portion has shearing angles that are inclination angles relative to the extending direction. The shearing angles includes a first shearing angle that is the shearing angle at each end portion and a second shearing angle that is the shearing angle at the center portion. The second shearing angle is larger than the first shearing angle.

Exemplary embodiments are directed to an apparatus for filling a central open space in a jar. The apparatus includes a base, an indexing station including a magazine, a blade, and a first actuator, a filling station including cartridges, and a second actuator. The magazine is rotatably mounted to the base. The platform of the cutting station is configured to receive a whole cucumber at a loading area and is incrementally indexed to reposition the whole cucumber from the loading area to a cutting area above the blade. The first actuator is configured to urge the whole cucumber through the blade and cut the whole cucumber into spears. The spears drop into and are held by one of the cartridges. The second actuator is configure to push at least one of the spears out from the cartridge into the central open space of the jar.

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.

The invention relates to a system (10) for transporting a film tube (2) in a blown film line (1) along a transport direction, having a guiding unit (51) for guiding the film tube (2), a bottleneck (13.1) at which a width (2.3) of the film tube (2) can be reduced, a severing apparatus (20) having at least one severing element (21) for severing the film tube (2), wherein the guiding unit (51) is arranged downstream of the bottleneck (13.1) in the transport direction of the film tube (2). The invention furthermore relates to a blown film line (1) and to a method (100) for producing a film.
