Abstract: The invention is directed to a die cutter monitoring system. In an exemplary embodiment the system includes a frame that supports a die. A counter plate is located opposite and aligned with the die. A substrate is placed between the counter plate and die. The counter plate forces the substrate into contact with the die. A force measuring device measures the force of the cutting stroke. The force measuring device generates an output signal. The output signal is analyzed relative to acceptable conditions and operating parameters. If the die cutter is operating outside of acceptable limits, an adjustment signal is generated and sent to the die cutter control system or operator.

Abstract: A mechanism for cutting an elongated material, such as insulated wire or fiber optic cabling. The cutting mechanism includes a stationary blade housing that includes a recessed blade receptacle. The blade receptacle receives an insert blade that is biased outward by a bias element. A cutting blade having a pair of guide legs is movable relative to the stationary blade housing and insert blade such that a cutting edge of the cutting blade interacts with a cutting edge of the insert blade to sever the elongated material.

Abstract: Improved steel rule for use in a cutting die for cutting fixed patterns in a single or plurality of stacked material layers according to the shape of the steel rule. The improvement in the rule assists in the removal of small pieces of scrap material through the bottom of the die. The rule is undercut so that the gap between adjacent cavities is tapered. The tapered gap between adjacent cavities creates a vertical passageway that becomes wider toward the bottom of the passageway. This greatly facilitates removal of scrap material through the bottom of the die. By allowing scrap material to escape through the die, the operators are not required to stop periodically to clean the die, and the likelihood of scrap material becoming trapped in the die is minimized. Thus, the speed of the cutting operation is increased and life of the die may be prolonged.

The dispersion of force required for tearing off the cut recording paper is reduced, a torn trace of a left part after cutting the recording paper looks nice, and the position of a left part after cutting the recording paper can be arbitrarily set respectively without increasing the size in the direction of the recording paper width.

Abstract: An optical encoder is mounted on the end of the shaft of one roller, which is in turn mounted on framework of the equipment and is driven by a film of material. A computer receives a number of impulses per roller revolution with such impulses transmitted from the optical encoder during the film's passing over the roller. Software of the computer is programed with the exact circumference of the roller before shipment and the computer calculates the amount of film that has passed over the roller and fires solenoid valves to precipitate punching operations based upon the distance traveled by the film. Upon receiving an electrical impulse from the computer control, a solenoid valve releases an intermittent burst of compressed air through a tube to a housing which contains a plastic actuator, a plunger and a spring and which has several holes drilled in it to facilitate movement of said compressed air. The burst of compressed air forces the actuator and plunger downward.
