Abstract: Provided is a cutting device that prevents a variation of shocks or impacts applied to a substrate during a cutting operation. The cutting device includes a pressing part; a cutting part disposed so as to move with respect to the pressing part so as to contact the substrate on an opposite side of the pressing part to thereby sandwich the substrate between the cutting part and the pressing part to shear the substrate; a first force generation part for generating pressing force to press the pressing part against the substrate; and a first adjustment part for adjusting the pressing force in response to the force applied from the substrate to the pressing part when the pressing part presses the substrate with the first force generation part.

Abstract: Disclosed is a repetitive stroke work system having an upper holder assembly configured to hold one or more work performing elements deployed on the upper holder assembly. The work performing elements are configured for lockable displacement on the upper holder assembly, with the displacement being along both X and Y axis relative to the upper holder assembly. The repetitive stroke work system also includes a workpiece repetitive positioning device configured with at least one initial work stop for use while performing an initial work operation and at least one subsequent work stop for use while performing subsequent work operations. The upper holder assembly is displaceable along a Z axis so as to bring the work performing elements in to operational contact with a workpiece deployed on the workpiece repetitive positioning device.

Abstract: A combined tool for edge-folding and trimming a rim of a panel includes a cutting blade rigidly secured to a tool holder frame, an edge-folding tool slidably received in the tool holder frame, and a biasing spring arranged in the tool holder frame to bias the edge-folding tool outwardly away from the holder frame. The tool is moved in a linear stamping direction, whereby the edge-folding tool folds back and then holds and compresses a margin of a panel workpiece. The tool holder frame and cutting blade are pushed farther in the linear stamping direction, while the edge-folding tool is pushed back into the tool holder frame and compresses the biasing spring, whereby the cutting blade cuts through and compresses the panel workpiece. This forms a back-folded, compressed, and trimmed rim of the finished panel in a single work step using an integrated edge-folding and cutting tool.

A back-up plate is provided to which the base is secured.

Abstract: Glass gob shearing apparatus having opposed shear blades that reciprocate along generally parallel, opposed horizontal paths to periodically bring the shearing ends of the shear blades into partly overlapping contact with one another, to thereby shear a gob of molten glass from a stream of molten glass flowing downwardly between the shear blades. Contact loads between the shear blades are reduced by placing a shim between one of the shear blades, namely the shear blade that is the lower of the shear blades when they are in contact with each other, to thereby impart a slight downward inclination to such shear blade with respect to the other shear blade. Contact loads between the shear blades are further reduced by resiliently mounting the other shear blade to the blade holder to which it is attached, and this is done by positioning curved spring washers between the other shear blade and the blade holder to which it is attached.

Abstract: A cutting mechanism for accurately cutting a notch in a piece of edging, to permit sharp bending of the piece of edging for a picture or plaque, is disclosed. The cutting mechanism comprises a jig secured to a base member, the jig being dimensioned to receive the piece of edging clamped thereto. A cutting blade is mounted on the base member for reciprocating movement between a first retracted position whereat the cutting blade is remote from the jig and a second fully extended position whereat the cutting edge has passed through the jig. The cutting blade has an inverted "V"-shaped cutting edge comprising two blade portions joined one to the other at a central vertex.

Abstract: A blade guide of a guillotine shear for flying transverse parting of strips, particularly steel strips. The shear having a shear housing in which blades fastened to blade supports are movable relative to one another on parallel guide paths for cutting and transversely to the guide paths in the running direction of the strip and at the running speed of the strip. The guide paths are arranged in a guide frame which is movable horizontally in the shear housing and the blade supports in the guide frame can be set in rotation by means of crank mechanisms which are supported in the shear housing and are associated with each blade support.

Abstract: An arrangement for cutting sheet metal, particularly sheet metal strips. The arrangement includes a double cutting tool with two outer knives and an inner knife which is movable between the outer knives so as to form two cutting gaps. The outer knives are adjustable relative to each other by adjusting wedges in order to adjust the cutting gaps such that the two outer knives are adjusted by the adjusting wedges synchronously or asynchronously by either the same or a different extent. The two outer knives can be clamped against the adjusting wedges.

Abstract: An auxiliary punching device is disclosed, which is attachable to a machine for punching holes at one given location into a stack of sheets of given size, in order to punch other holes at another given location in the same stack at the very same time as the holes are punched at the one location. This auxiliary punching device comprises an auxiliary die and an auxiliary punching tool that are attachable to the main die and punching tool of the punching machine to work in unison therewith. Both of the structural elements are very easy to adjust to fit any required positioning or configuration for the second row of holes to be punched, whatever be the size of the stack of sheets fed to the machine.

Abstract: A high-precision punch and die apparatus having a stationary frame; a punch movable relative to the frame, the punch including integral pneumostatic bearing surfaces and at least one cutting edge; and a die adjustably mounted to the frame to receive the punch therethrough, the die including at least one cutting edge coactable with the cutting edge(s) on the punch. A pair of pneumostatic bearings are provided to constrain and guide movement of the punch through the die, each bearing having a segmented journal that includes a plurality of journal segments formed with a pneumostatic bearing surface, the journal segments being adjustably mounted, relative to the frame, to receive the punch therebetween so that the bearing surface on each journal segment is in closely spaced relation to an opposing one of the bearing surfaces on the punch.

Abstract: A multiple gob glass shearing mechanism in which the sets of opposed shear blades are supported for movement toward and away from each other in a straight line or with parallel motion. One set of shears is mounted on a shear guide that can be adjusted up or down relative to the holder of the opposed set of shears. This adjustment is for the purpose of adjusting the tension on all the sets of blades simultaneously and can be affected when the shears are in operation. The drive for the shears may be unlatched for safety purposes when out of position and when put back into operation the shear blades will not close unless the latch is refastened.
