Abstract: The present invention relates to a thermoform packaging machine comprising a film punch unit that includes a stroke drive for moving a die and a punch. The die and punch are movable, by means of the stroke drive, towards and away from each other orthogonally to a film conveying plane. The stroke drive is arranged above the film conveying plane.

Abstract: A cutter includes a cutting part including a movable blade and a fixed blade, the movable blade being configured to be moved by a drive mechanism; an operation part configured to cause an edge of the movable blade to move in an arc by causing the drive mechanism to be driven; and a blade pressure generation part configured to cause a blade pressure to be generated between the movable blade and the fixed blade.

Abstract: A cutting device includes a conveyance unit for conveying a recording medium in a conveyance direction, a guide configured to guide a recording medium, a blade movable in a direction intersecting with the conveyance direction, for cutting the recording medium when the blade moves with a leading end side thereof inclined to the upstream side, a presser member movable to a first position where the presser member holds down the recording medium and to a second position where the presser member does not hold down the recording medium, wherein the presser member holds down the recording medium at a position separated farther than a thickness of the recording medium from the guide in the first position, and wherein the presser member holds down the recording medium at least from before the blade starts to cut the recording medium to when the blade is cutting the recording medium.

Abstract: An apparatus, system, and method for cutting tubes has a scarf cut made in a direction transverse to a cut-off direction. The scarf cut passes through a thickness of a tube wall and forms an opening that receives a tip of a cut-off blade. The cut-off blade has cutting edges with an angle that engage ends of the opening such that a slug is forced upward and outward relative to the tubes. The scarf blade, the cut-off blade, and a clamping jaw may be moved in a coordinated manner by separate drivers operated under control of an electronic controller.

Abstract: The triple action cam die set has an upper die, lower die and a cam system that works on multiple axes. A feeder delivers tubes sequentially to a loading station from where the tube is moved to a work station where the ends of the tube are cut and then the cut tube is moved to an exit station. The upper die has pairs of first, second and third drivers, each driver having a caming surface thereon. The lower die has a pair of cutter holders with cutters located opposite the ends of the tube when located at the work station. The cutter holders have first, second and third cam surfaces thereon which are sequentially engageable by the cam surfaces provide on the first, second and third drivers when the upper die is cycled.

Abstract: A photo cutting apparatus includes a support, a press, a linkage and a cutting device. The press is movably mounted on the support. The linkage is for pressing the press. The cutting device is arranged between the support and the press for separating photos developed on a sheet from one another in a single action.

Abstract: In a shear a workpiece is pressed by a holddown against a stationary blade so as to leave a piece to be cut off projecting past the blade, a movable blade is displaced forward past the stationary blade to cut off the piece, and a cut-off holder is pressed in back against the piece by a fluid-powered holding cylinder and moves back in the direction as the piece is cut off. Pressure is substantially completely relieved in the cylinder as soon as the movable blade starts to cut through the workpiece so that the cut-off holder does not substantially resist forward movement in the cutting direction. The movable blade is pressed forward in the direction against the workpiece by a main cylinder so that pressure in the main cylinder reaches a maximum level just before the movable blade starts to cut through the workpiece. The pressure in the main cylinder is monitored to trigger relief of pressure in the holding cylinder when the monitored pressure starts to decrease from the maximum level.

Abstract: A shear machine for irradiated nuclear fuel elements has a replaceable shear assembly comprising a fuel element support block, a shear blade support and two clamp members which hold the fuel element to be sheared in contact with the support block. A first clamp member contacts the fuel element remote from the shear blade and a second clamp member contacts the fuel element adjacent the shear blade and is advanced towards the support block during shearing to compensate for any compression of the fuel element caused by the shear blade.

Abstract: A process and device for transforming a single pressure force into separate pressure forces in the processing of material, especially for energizing a punch and a stripper when holes of small dimensions are punched in material which is relatively thick with respect to these holes, wherein the separate pressure forces are directly dependent on each other and on the tensile strength of the material to be worked on.
