Abstract: It is to provide a paper cutter which can tear an uncut portion of paper easily and prevent from reeling out the paper from the device even when the uncut portion of the partial cut paper is pulled straightly. In a paper cutter having a guide 21 for guiding continuous paper R and cutting means for cutting the continuous paper R passing through the guide 21 with its one portion uncut, two projections 2a and 2b protruding in contact with the both surfaces of the continuous paper R are provided on a path of passing the two separated portions and the root-around portion R2 in the vicinity of the root R0 of the continuous paper, and when the tensile force works on the continous paper R passing through the guide 21, owing to these projections 2a and 2b, the lower portion of the root-around portion R2 of the paper is downwardly drawn, hence to provide an aperture in the portion around the root R0.

Abstract: A hand-held optical fiber cutting apparatus comprises a base, and a cutting device and a bending device, comprised of a pushing shaft mounted on the cutting device, that slide to perform cutting. The base includes an optical fiber guiding support to receive the optical fiber to be cut. Via a manual switch, an optical fiber clamp pivotably mounted onto the base can rotatably open or close to clamp the optical fiber. The bending device further includes a bending base pivotably assembled with the base. To cut the optical fiber, the cutting device and the pushing shaft slide toward the clamped optical fiber that is sequentially precut via a cutting blade of the cutting device and then cut off via a rotation of the bending base pushed by the pushing shaft.

Abstract: The invention describes a method and an apparatus removing a plurality of die-cut products from an operating area of a die-cutting apparatus having multiple dies. The die-cut products are simultaneously picked up at a pick-up point in the operating area. Then, they are simultaneously moved to a delivery point outside the operating area. At the delivery point, the die-cut products are released simultaneously. The operations of picking up moving and releasing are carried out in such a manner that the die-cut products at the delivery point are situated at substantially at the same position with respect to one another as those which they adopt at the pick-up point.

The sheet cutting apparatus includes a conveying device for conveying a booklet; a stopping device for stopping the booklet at a predetermined position; a cutting device for cutting the front end portion of the booklet; and a controlling section to control each of the conveying device, the stopping device and the cutting device. The controlling section controls the stopping device so as to variably determine a stopping position of the booklet stopped by the stopping device, based on a number of sheets included in the booklet conveyed to the cutting device by the conveying device.

Abstract: A method and apparatus for collecting and removing chaff from an internal drum imaging system. The chaff collection apparatus includes a chaff tray coupled to the internal drum below the side punches. The chaff tray includes a cover comprising a plurality of evenly spaced frangible fingers. A specific set of the fingers is removed from the cover according to the locations of the side punches on the internal drum. In this manner, only the portions of the cover below the side punches are open to the interior of the chaff tray. The chaff produced by each punch passes into the chaff tray through a respective opening in the cover, and is captured within the chaff tray. The areas of the cover of the chaff tray that are not located below the side punches remain covered by the remaining frangible fingers, thereby preventing chaff from escaping the chaff tray.

Abstract: A machine tool control system is provided that is capable of detecting a one-sheet takeout failure. The system includes a workpiece takeout schedule which indicates the plate thickness and number of sheets to be taken out from a stack of workpieces for each product. A one-sheet takeout sensor is also provided to detect when a one-sheet takeout device fails to takeout or suck one-sheet from the pallet of workpieces. In addition, the system includes a restoration setting key which permits an operator to select one of a plurality of modes to continue control operation of a machine tool with a controller when a one-sheet takeout failure is detected. When information from the one-sheet takeout sensor indicates a one-sheet takeout failure, based on the set mode of the restoration setting key, the controller changes the measuring range, the accumulating place for the sucked workpiece, or skips the workpiece takeout schedule based on a detected plate thickness.

The chute has a top wall and inner and outer sidewalls shaped so that chips exiting the head through the window are directed along a chip path which is generally parallel to the tangent plane and first turns further rearward and then turns outward through a lateral discharge opening in the chute.

Abstract: As it is intermittently supplied, a blank wire having a generally Y-shape cross section is cut into slices of a predetermined thickness by a cutting punch, which is fixed to the frame, and a coacting cutting die, which is reciprocatingly movable in the cutting direction. Then a bulge is formed on the head portion of the cut coupling element by a bulge forming die, which is connected with the forward end in stroke direction of the cutting die, and a coacting bulge forming punch, which is movable upwardly and downwardly. The cutting punch is equipped with preventing means on the upper side of the end of a blade for preventing the cut coupling element from jumping up from the blade, so that a bulge can be formed on the head portion reliably, without giving any damage to peripheral equipments.

Abstract: A leading edge of a web is fed to an upstream cutting station and is gripped at the cutting station with an upstream clamp which is then advanced downstream away from the cutting station to a middle station and is arrested in the middle station where the leading edge of the web is gripped with a downstream clamp and released from the upstream clamp. The leading edge held by the downstream clamp is then moved downstream to a holding station and the opened upstream clamp is moved along the web to a position slightly upstream of the upstream cutting station. The web is then gripped immediately downstream of the upstream cutting station with an upstream clamping conveyor and immediately upstream of the downstream holding station with a downstream clamping conveyor, and is gripped immediately upstream of the upstream cutting station with the upstream clamp.

Abstract: An apparatus and method are provided for receiving products, such as stacks of sliced luncheon meat, in an intermittent flow pattern, for conveying the products in two generally parallel paths at two different flow rates, and for merging the two generally parallel paths into a single path through which the products flow on a non-intermittent basis. The two generally parallel paths have a fill mode during which an intermittent grouping of products are received onto the conveyor path, as well as a feed mode during which the intermittent grouping of products are fed in a continuous flow to a merging device. When one of the conveyor paths is in its fill mode, the other conveyor path is in its feed mode, and vice versa. The speed of each conveyor path during its fill mode is greater than that during its feed mode.

Abstract: In a method and apparatus for cutting and welding slugs to lead wires, a die has a bore therein through which the slug feedstock is stepwise advanced. The die is ferromagnetic and a permanent magnet is positioned with one magnetic pole adjacent the cutting end of the die. A knife has an opening therein for receiving the feedstock advancing out of the die when the hole and die are aligned. Rocking of the knife cuts free a slug. When the knife is rocked back into alignment, the slug positions itself on the freshly cut end of the feedstock. Advance of the feedstock then pushes the slug out of the knife and presents it to a clamp.
