A metallic stamp and die for the craft industry comprises a predetermined acid-etched design on a surface of a metallic plate. A first layer of a metallic paint is applied over the front and back surfaces of the metallic stamp and die. A second layer of a rubber paint is applied over the metallic paint. The metallic paint facilitates bonding of the rubber paint to the metallic plate and increases the life of the coating of the rubber paint. The rubber paint is configured to absorb and store an ink and facilitate transfer of the ink to one or more substrates, thus enabling stamping of the design on the substrate. The metallic die can be configured for a plurality of uses, such as embossing, cutting, heat-foiling, stamping, scoring, and inserting patterns or designs in a plurality of substrates.

The invention relates to steel-rule cutting dies having a die block with at least one kerf configured to receive a corresponding steel-rule intended to be partially inserted into the kerf. The die block also has at least one element having magnetic properties, such as for instance a magnet, located or embedded in proximity to each kerf for providing a magnetic field that retains the steel-rule when the steel-rule is received into the corresponding kerf. The presence of the magnetic element(s) in proximity to the kerf(s) allows maintaining the corresponding rule(s) in position within its kerf even if the kerf is cut “loosely”. The corresponding rule may be quickly and easily inserted and accurately maintained even if the die block expand or retract under atmospheric variations. Among other advantages, the invention allows better stability of the cutting-die, faster leveling on press, and increased the number of re-knifing and longer run-time.

A system and a method for compensating misalignments of a die for cutting cardboard of a die cutter. The system comprises a processor configured to detect height-correcting elements in an image of a correction template for the die, and further configured to produce a digital file comprising a digital representation of detected height-correcting elements; and an optical device for projecting images configured to project the digital representation of the digital file on a pressure compensation plate of the die cutter. The method comprises digitally detecting height-correcting elements in an image of a correction template for the die; producing a digital representation of detected height-correcting elements; and projecting the digital representation on a pressure compensation plate of the die cutter.

Apparatus (1) for changing a blade of a rotary die cutter, particularly for flexographic printing machines: a magnetic cylinder (3) configured to receive and support a die-cutting blade (5, 5′); a station (7) for inserting the blade (5, 5′) has a retention device (70) configured to retain the blade (5) in the insertion station; a guiding device (71) guides the blade (5, 5′) toward the magnetic cylinder (3); a station (9) for extracting the blade (5, 5′), has an extraction device (90) configured to remove the blade (5, 5′) from the magnetic cylinder (3).

A tool unit (II) includes an ability to change the width (B) of a punching gap between a first tool (12) and a second tool (13). A plurality of second tools (13) jointly form a die tool with a circumferential die cutting edge in which the first tool (12) can engage with a cutting edge (22). Between the cutting edge (22) of the first tool and the respective cutting edge (21) of a second tool (12) a punching gap (23) is formed with a width (B) measured between the cutting edges (21, 22) across the working direction (A). Via lamping means (33), the deformation force acting on a second tool (13) can act transversely to the working direction (A), whereby the position of the affected cutting edge (21) and, with it, the width (B) of the punching gap (23), can be changed and set.

Apparatuses and methods for cutting a facestock on a liner. An anvil roller receives facestock on liner. A cutting roller, under a force, cuts facestock between the cutting roller and the anvil roller. At least one support roller supports the cutting roller and, optionally, the anvil roller, thereby distributing the force into two or more portions and/or subportions, in two or more directions. Apparatuses, methods and kits for preparing a cutting surface of a cutting roller in a facestock cutting apparatus, or for extending the usefulness of a cutting roller. An equalizer roller is provided in a position adjacent to the cutting roller. The equalizer roller has an equalizing surface having a hardness at least as hard as a hardness of the cutting surface. The cutting roller is rotated against the equalizer roller such that the cutting surface is equalized by the equalizing surface.

A flat die magnetic holding base is provided for holding a metallic, flat die. The base can be formed from a metal plate having a front surface and a planar back surface. The front surface can include a planar mounting area. The planar back surface can have a plurality of recesses formed therein. The metal plate has three or more corners, each corner having a through-hole formed therein. Magnets are permanently fixed in recesses formed in the back surface. The magnets are oriented in the recesses such that a magnetic field is generated by the magnets in a direction that magnetically attracts and holds a metallic, flat die, to and on, the planar mounting area. The flat die can be a magnetically-attractable, milled-plate, flexible die. Alignment pins extend away from the planar mounting area and align with through-holes of the metallic, flat die to register the metallic, flat die on the mounting area.

A die cutter includes an anvil cylinder, a die cylinder, and a sleeve that is mounted on the die cylinder for generating a pressing force on an anvil cover to force a locking component of the anvil cover into a locking component receptor of the anvil cylinder.

Applying padding material around shaped cutting blades includes: receiving a blade shape diagram and a rule of blade; bending the rule of blade according to the blade shape diagram to produce the shaped cutting blades; and applying the padding material around the shaped cutting blades using the blade shape diagram to produce a padded shaped cutting blade, wherein the padding material provides a spring action to quickly detach the shaped cutting blades from a plate matter.

The present disclosure is a cutter assembly, which mainly includes a carrier and a plurality of cutters, wherein the cutters are disposed on the carrier. Each of the cutters includes a blade and a cutter seat. The cutter seat has at least one upper-adjusting hole and at least one lower-adjusting hole, wherein the upper-offset hole is formed with a diameter greater than that of the lower-adjusting hole, and the upper-adjusting hole and the lower-adjusting hole form a countersink surface therebetween. At least one first fastener passes through the upper-adjusting hole and the lower-adjusting hole and engages with the carrier. The first fastener has a top portion formed with a diameter greater than the lower-adjusting hole and less than the upper-adjusting hole, the top portion of the first portion does not press against the countersink surface between the upper-adjusting hole and the lower-adjusting hole.
