Patent number: 11833705Abstract: 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.Type: GrantFiled: August 1, 2022Date of Patent: December 5, 2023Inventor: Paolo Quercia

Patent number: 6178852Abstract: A pair of rotary die cylinders having co-acting cutting blades formed by integral lands projecting generally radially outwardly from the main body of each cylinder and a method of making them by rough machining a tool steel workpiece with conventional cutting tools to form the general contour and path of the cutting blades and thereafter final machining and simultaneously heat treating the cutting blades with a laser to provide an accurately formed and hardened cutting blade. Preferably, the rough machining with conventional cutting tools and the final machining and heat treating by a laser are performed with the same machine tool, such as a computerized numerical control (CNC) machining center. Such a machining center permits rapid and accurate rough machining as well as accurate final laser machining of the cutting blades.Type: GrantFiled: November 25, 1998Date of Patent: January 30, 2001Assignee: Atlantic Commerce PropertiesInventor: Alan R.

Patent number: 6170376Abstract: In a die board for cutting and/or creasing sheet-type work material, a base is provided that includes a first upper surface and a second lower surface. At least one slot extends along the first upper surface and includes a first slot section extending from said first upper surface at least part-way through the die board base. The at least one slot also includes a second slot section extending from said second lower surface at least part-way through the die board base. The first and second slot sections each have a width with at least one of the slot section widths being adapted to grip and retain at least one die-board rule.Type: GrantFiled: March 17, 1999Date of Patent: January 9, 2001Assignee: Gerber Scientific Products, Inc.Inventors: Wolfgang M. Strobel, David J. Logan, David J. Gerber

Patent number: RE37366Abstract: A method of making a pair of rotary die cylinders with lands having coacting cutting edges which cut blanks from a web of material passing through the nip of the rotating dies. In cross section each land has an outer face and a pair of spaced apart side faces which are parallel to each other and perpendicular to the chord of the outer face to provide a clean cut and facilitate release of the cut blank from the cutting blades as it emerges from the nip of the dies. The die cylinders are journalled for rotation by recesses with frusto conical locating surfaces in their opposed ends. Each die cylinder is made by machining the recesses in the opposed ends of a generally cylindrical workpiece of tool steel and then utilizing the recesses to locate and orient the workpiece relative to a cutting tool to produce a cylindrical surface on the workpiece concentric with the axis of the recesses and then to machine away portions of the periphery of the cylindrical surface to form the cutting blade lands thereon.Type: GrantFiled: November 19, 1998Date of Patent: September 18, 2001Assignee: Bernal International, Inc.Inventors: William Allen Cox, Alan Rae Pfaff
