Abstract: The invention is directed to a cutting post for mounting on a cutting apparatus and to the cutting apparatus. The cutting apparatus has at least one cutting blade and at least one cutting post. The cutting post includes at least one receptacle for the cutting blade and at least one cutting element having a cutting edge arranged at the head end of the cutting post. The cutting blade has a cutting blade edge and is held in the receptacle of the cutting post. The cutting blade edge of the cutting blade and the cutting edge of the cutting element of the cutting post conjointly form a continuous cutting contour.

Abstract: It is intended to improve work efficiency by eliminating the work of attaching and removing push rods during installing and dismounting the a blade mount and also to reduce abrasion of the push rods for pushing punching scrap out of a punching blade. The first push rods 18 are inserted movably in the first through-holes 16 formed in the knife cylinder and the second push rods 36 are inserted movably in the second through-holes 34 formed in the blade mount to permit the second push rods 36 to be abutted on the first push rods 18. A scrap push lever 30 is mounted on the outer end of the second push rod 36 to push out the punching scrap a and an eccentric cylinder 14 is provided inside of the knife cylinder 10 to push the first push rod 18 outward when pushing out the punching scrap a. The stroke of the first push rod 18 is controlled so that the outer end 18a of the first push rod 18 does not project from the outer periphery 10a of the knife cylinder.

Abstract: A closed-knife rod cutting machine is provided with air ejection apparatus for automatic discharge of cut rods. The gage pin is compliant in the direction of the knife return stroke to permit ejection of a lodged cut rod by the advancing rod stock. The free end of the compliant gage pin is tapered to assist in clearing cut rods loosely lodged in knife, and the gage pin is timed to retract when the knife engages the rod stock at the beginning of the cutting cycle.

Abstract: A die board assembly includes a support plate providing a plurality of through holes arranged along lines of an X-Y grid pattern. The support plate further provides a plurality of shaped apertures positioned within the support plate to a selected depth. One of the apertures is positioned between each pair of the through holes, the apertures providing aperture legs coincident with the lines of the X-Y grid. A plurality of rigid cylindrical receivers are adapted for engagement within one of the through holes and a plurality of resilient bumpers, are engaged within the cylindrical receivers for support thereof, each of the bumpers being segmented into a plurality of segments with segment spaces in separation thereof.

Abstract: A die cutting block for forming die cuts from paper and other materials includes a base portion having a recess formed therein having a desired shape formed therein, an insert portion having an outer contour which substantially matches the contour of the recess and a blade interposed between and tightly held between the base portion and the insert portion. The blade extends above the base portion and insert portion to provide an exposed edge for cutting paper and the like into a desired shape.

Abstract: In a perforating apparatus which has a holder to which a perforating blade can be fastened, the perforation is produced via the movement of a piston by the piston pressing against an air cushion, which in turn transmits this pressure to a perforating piston which presses the perforating blade downward. A positioning device which directly varies the position of the piston unit relative to the housing surface is provided for the zero setting of the piston.

Abstract: A magnetic cutting assembly and waste removal system is provided for cutting a panel from an envelope blank or the like. The die holder has a magnetic outer surface and a plurality of surface orifice therein radially communicating with corresponding feed tubes for supplying vacuum or air to the surface and into the vicinity of the envelope blank. In order to maximize the number of orifices while minimizing the number of magnetic members, the magnetic members be disposed in a plurality of rows wherein each row contains alternating magnets and orifices and a row of orifices are disposed between each adjacent row of magnets.

Abstract: A method of cutting stacked layers of compressible material utilizing a steel rule cutting die. An open cell foam member is placed in the area between spaced portions of the cutting die to define a flat upper surface substantially flush with the sharpened upper edge of the cutting die. The stacked layers of compressible material are placed on top of the foam member and on top of the sharpened upper edge of the die and the upper platen of the associated press is lowered to precompress the stacked compressible layers prior to the cutting operation by the die. The foam member is an open cell member and has a compressibility such that it maintains a flat upper face flush with the upper cutting edge of the die during the precompression of the layers and thereafter moves downwardly in a smooth translatory manner to allow the layer to be moved downwardly through the cutting die.

Abstract: A cutter of the present invention comprises a punching member having a punching edge and a receiving member for receiving the punching force of the punching member, the receiving member having a sandwich structure comprising two plate materials and an elastic body held therebetween. Therefore, the receiving member is capable of elastically holding the punching edge during punching.

Abstract: In an apparatus for punching out a part from a workpiece or blank, particularly for punching out a segment from a photograph, for the engagement of the workpiece a punching table is arranged under a punching plate which can be rotated away and lowered in direction x, a punching pattern being placed on the workpiece.

Abstract: A die ejecting plate has a large block of rubber bonded to one of its planar surfaces and is fixedly attachable to a topmost portion of a conventional paper cutting die. Once attached to the paper cutting die, the ejecting plate is so positioned that the block of rubber extends downwardly into the die. A die cutting press may then be used to drive the paper cutting die through a stack of paper, and once the hammer of the press is removed from contact with the die, the block of rubber serves to forcibly extract the die from the material cut.

Abstract: There is disclosed a printing, feeding and severing method and apparatus for carrying out the method. The apparatus includes a print head assembly and a platen assembly movable relatively toward and away from each other into and out of printing cooperation, mechanism for inking the print head assembly, mechanism for feeding a web of record members to between the print head assembly and the platen assembly, the web being in roll form and there being means to assist the gradual unwinding of the roll with gradual paying out of web material from the roll to the feeding mechanism, an idler contacting the web and disposed at a slight angle to the direction of feed of the web to cause the web to follow a feed edge, record severing means disposed downstream of the print head assembly and the platen assembly, and a modular support assembly of a print head of the print head assembly.
