Abstract: An apparatus and a method for automatically applying, without the intervention of an operator, rubber elements on a die-cutter during the manufacturing step thereof, are described. The apparatus comprises a manipulator, preferably a robotic arm, and a needle gripper. The gripper withdraws the water jet pre-cut rubber elements from a sheet with double-sided adhesive tape, and places them one by one at the point provided for by the working program.

Abstract: A broaching unit for rules of die cutters which comprises a supporting structure, for example a frame, a guide of a die cutter rule, and a tool-holding arm equipped with at least one broaching tool is described. The guide defines a sliding surface on which the rule is fed intermittently. The tool-holding arm is mounted on the supporting structure and is susceptible to reciprocating movements with respect to it and with respect to the guide, preferably forward and backwards movements along a transversal direction of the rule, just to intercept the die cutter rule with the broaching tool when the rule is stopped. Advantageously, the tool-holding arm is equipped with at least two broaching tools, for example four tools, and can be oriented with respect to the guide, for example can rotate on itself, to selectively activate one of the broaching tools, i.e. to bring one of the tools into contact with the rule.

Abstract: A method of making a counter-die cutter for a die cutting machine having a die cutter and respective counter-die cutter includes: acquiring a digital drawing of a die cutter to be made, which is provided with comparing means; acquiring a digital drawing of a respective counter-die cutter to be made; providing a wooden support of the die cutter; making a plurality of comparing means on the support of the die cutter; making the die cutter; detecting the position and/or orientation of the comparing means of the finished die cutter; comparing the detected position and/or orientation with corresponding position and/or orientation of the comparing means being in the digital drawing of the die cutter; modifying the digital drawing of the counter-die cutter based on the detected differences to adapt the digital drawing to the finished die cutter; and making the counter-die cutter based on the modified digital drawing.

Abstract: A device and a process are described for bending a metallic strip (W) by means of bending tools (3, 4) which can rotate around a common axis (M) near a guide aperture (1) through which the metallic strip to be bent is fed. Controllable blocking means (5-8) are provided to lock the bending tools in positions mutually alongside the guide aperture when they are in the rest condition, and to release at least one of the bending tools in the operating condition in which the bending is performed.

Abstract: A method is provided for producing a laminar male die of the interchangeable type, for printing Braille characters on yielding supports. The method includes the step of punching the metal foil that forms the body of the male die to obtain a plurality of first points in relief on a first face of the foil. The first points define one or more characters in Braille alphabet. The method further includes punching the metal foil to obtain at least two second points in relief on the other side of the foil; the second points in relief are aligned with corresponding receiving seats of an outer male die-holding support. A male die obtained by the method and the respective manufacturing apparatus are also described.

Abstract: A device and method for bending a metallic strip (1), particularly for manufacturing die cutting blades. The bending tools (20, 30) are capable of being rotated about a common axis (15) and wherein each tool (20, 30) is further capable of being rotated about its own axis (25, 35) of rotation which is different from each others (15, 25, and 35).

Abstract: The present invention relates to an apparatus and a method for embossing raised dots (B) on plate elements (A), at least partly plastically deformable. The apparatus comprises at least one punch (31) movable alternatively along a first direction (Z) to emboss a raised dot (B), on a plate element (A) which rests, on a work surface intercepted by said first, direction (Z). Advantageously, the apparatus also comprises a feed device (2) of the plate element (A) along a second direction (X), which can be operated to feed new sections of said plate element (A) to the punch (31). The punch (31) can be translated along a third direction (Y), orthogonal to said first direction (Z), to emboss at least another raised dot (B) along a same section of the plate element (A).

Abstract: A device and method for bending a metallic strip are described, particularly for manufacturing die cutting blades, wherein the bending tools are capable of being rotated about a common axis and wherein each tool is further capable of being rotated about its own axis of rotation which is different from the others.
