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 cutting apparatus including an apparatus frame and a cutting station, for forming interconnected bags, is provided. The cutting station includes a rotary anvil having an axis of rotation and mounted to a first frame structure, a rotary cutting die disposed adjacent to said rotary anvil and having an axis of rotation parallel to said first axis of rotation, said rotary cutting die including a rotatable cylindrical shaft carrying a die blade, said rotary cutting die being mounted to a frame structure, and an adjustment mechanism for varying the distance between said anvil and said cutting die, said mechanism including a rotatable spindle having threaded portions of different pitch. A first threaded portion engages a threaded portion of said first or said second frame structure and said second threaded portion engaging a threaded portion of said apparatus frame.

A press working method for forming by a press working apparatus, in a film material made of resin, a passage hole through which a fluid for a fuel cell flows, includes a placing step, a gripping step, and a piercing step. In the piercing step, a secondary die and a holder grip an outer peripheral portion of the film material. In the piercing step, a piercing punch punches out the film material is a state in which the press working apparatus does not contact an upper surface of the film material in an adjacent portion surrounding a portion to be punched out by the piercing punch.

A system may include a blade die, a first clamping caul positioned on a first side of the blade die, and a second clamping caul positioned on a second side of the blade die. A molding surface of the blade die and a molding surface of the first clamping caul may be configured to bend a first interchangeable blade positioned therebetween into a first shape in response to a first compression force. A second molding surface of the blade die and a molding surface of the second clamping caul may be configured to bend a second interchangeable blade positioned therebetween into a second shape in response to a second compression force.

Punched and incised portions can be formed properly, in which it is not necessary to replace an anvil depending on a type of a sheet material. A punching unit 51 comprises: a punching blade 50 for punching a first panel material 11, a second panel material 12, an open tape and a mounting base portion so as to form a punching portion; a incising portion 51 for incising the second panel material 12 and the mounting base portion disposed on the open tape so as to form a incising portion; and an adjusting portion 54 for adjusting a first gap 56 in a punching direction 5Z between edges 50A and 51A of the punching and incising blades 50 and 51.

A system and method for aligning and installing graphical dies onto an embossing press or foil stamping press is provided. The system includes a number of die support panels having a number of threaded openings disposed in columns and rows in a grid like fashion and identified with x and y axis indicia. The system also includes a number of dies with a number of apertures each identified with a pair of x and y axis indicia. Fasteners and indicia are used to align and attach the dies to the die support panels in a predetermined position. The system preferable further comprises one or more adjusters used to make minute positioning adjustments to the die after it is installed on the panel.
