The invention provides a method of cutting out an opening in a flat cardboard blank (10, 12) that is for use in manufacturing a package, wherein a first portion (18) of the blank (10, 12) and an ejector tape (34) that face each other are pressed together between a presser tool (24) and an activation tool (26) that face each other so as to cause the ejector tape (34) to stick exclusively on the first portion (18) of the blank (10, 12). The invention also provides an ejector tape for such a method.

Space in a conduit having at least one cable therein which is surrounded by a duct is recovered by longitudinally cutting the duct and removing the duct from around the cable. The duct may be pulled out of the conduit and past a blade to affect the cutting, or a blade may be pulled through the conduit to cut the duct while still in the conduit.

A waste recycling mechanism is disposed on a film cutting machine and includes a fixing plate fixed to a cutting template of the film cutting machine, a pressing-head device disposed on the fixing plate, a tape, a tape reel and a collection device disposed on a platform of the film cutting machine. The tape is wound on the tape reel and is connected to the collection device after being wound on the pressing-head device. When the fixing plate moves downward with a cutting motion of the cutting template, the pressing-head device presses a film waste to make the tape attached to the film waste. When the fixing plate moves upward, the collection device reels in the tape to make a portion of the tape having the film waste separate from the pressing-head device and make a portion of the tape without any film waste wound on the pressing-head device.

A cutting assembly for cutting a meat or food product passing along a path of travel and comprising a blade assembly including a cutting roller having a plurality of cutting blades radially mounted thereon and movable relative to the path of travel. A mating assembly interacts with the plurality of cutting blades to accomplish a multipoint cutting procedure which is facilitated by the concurrent rotation of the cutting roller and cutting blades as well as a linear reciprocal travel thereof transverse to the path of travel. A stabilizing assembly is provided to restrict the dimensional variance of the spacing between the cutting roller and mate roller through which the meat product travels and an ejecting assembly to remove cut portions from between the cutting blades and back onto the path of travel. The cutting assembly preferably includes a modular construction disposal within and removal from an operative position along a processing line associated with the path of travel.

A waste stripping unit in a packaging production machine (1), positioned downstream of a cutting unit (3) for cutting one or more flat substrates (4). The stripping unit includes a frame (16) supporting two rotary tools cooperating with one another (17, 18). At least one of the two tools (17, 18) is formed with a mandrel (27) and a removable sleeve (28), and the sleeve can be inserted on, fixed to and driven in rotation by the mandrel (27). One tool has protruding needles for the stripping and the other tool has a flexible strip cooperating with the needles.

A cutting device includes a fixing plate, a revolving cylinder, an annular cutting blade, and an ejection bar. The fixing plate defines a first through hole. The revolving cylinder is threadedly engaged in the first through hole and defines a second through hole. The cutting blade defines a third through hole and is attached to the revolving cylinder. The revolving cylinder is rotatable relative to the fixing plate to move the cutting blade between an extended position and a retracted position. In the extended position, the cutting blade cuts a surface of the workpiece to create a round blind crack in the surface thereof, a portion of the workpiece being surrounded by the blind crack. In the retracted position, the cutting blade is moved away from the workpiece. The ejection bar is configured for pushing the surrounded portion out of the workpiece.

A method for manufacturing the cushioning elements may include utilizing a die with a plurality of die elements positioned in a particular arrangement. A polymer material, which may be a polymer foam material, is located between the die and an extractor. The polymer material is compressed between the die and the extractor, and the die elements cut the polymer material to form a plurality of pad components, which are arranged like the die elements. The die and the extractor are separated, and the pad components are secured to the extractor in the arrangement of the die elements. Additionally, the pad components are bonded to at least one material layer such that the pad components remain in the arrangement of the die elements.

The cutting machine includes at least one log feed channel; a cutting station along the feed channel, with at least one cutting blade for dividing each, log into individual rolls plus front and rear trims; a log feed device along the feed channel, including at least one rear member for pushing the logs to be cut, movable along the feed channel to push each log through the cutting station. The feed device also includes at least one front member for engaging with the log to be cut, arranged and controlled so as to engage frontally with each log, or series of rolls obtained after the log has been cut, for at least a part of its travel along the feed channel.

There is provided a green sheet through-hole machining apparatus, and a through-hole machining method, that allows deterioration of positional precision of through-holes after perforation to be readily prevented. A releasing plate made of a metallic thin plate is removably set on an upper face of a lower base. Then, a green sheet is interposed between the lower and upper bases and the upper base is pressed by a pressurizing roller to press the green sheet toward the releasing plate. Then, the green sheet is punched by the projections to perforate the through-holes. After that, the green sheet is removed from the lower base together with the releasing plate.
