    Abstract: A calibration procedure is carried out for determining the displacement distance from a reference point to the center of the blade in a web cutter in a mail inserter. A photosensor is placed near the paper plane of the web cutter to sense a web edge at the reference point downstream or upstream from the blade. At the start of the calibration procedure, the blade is caused to cut the web for providing a web edge. The web edge is moved in a backward and forward motion over the photosensor a few times for determining the theoretical center position of the photosensor relative to the position where the web is cut by the blade. By taking into account the chip-out width, the displacement distance from the center of the photosensor to the center of the chip out blade can be determined.

  • Patent number: 5244067
    Abstract: A detector on a wire lead machine includes a pair of contacts biased into a normally closed position. The wire is fed between the contacts, keeping the contacts open, and the insulation on the wire prevents electrical conductivity between the contacts. If the wire runs out, the contacts close to shut off the machine. Additionally, a splice on the wire establishes an electrical path between the contacts and, again, the machine is shut off. The detector includes a detection circuit which generates a control signal. In the event a splice is passing through the contacts, the detection circuit generates a control signal having a relatively short time duration (as for example, 100 microseconds) and holds the signal for a sufficient time period (as for example, 500 milliseconds). This allows a suitable control means (which may include a microprocessor) to shut off the machine because of either wire runout or a splice on the wire, thereby preventing serious damage to the machine and maintaining productivity.

  • Patent number: 5237896
    Abstract: There is disclosed an interlock between a wood working tool and a dust control system in which a standard pressure switch, which can be activated by negative or positive pressure, is located in the dust collector duct which extends to the wood working tool. The switch is electrically connected to the magnetic starter for the wood working tool. The pressure switch responses to a sensed condition of subatmospheric pressure in the dust collector duct to provide power to the woodworking tool, thus insuring that the dust collector system must be functioning to permit operation of the wood working tool. When the dust collector duct becomes blocked or the dust collector fails to function for any reason, the pressure in the duct rises, automatically activating the interlock and interrupting the power supply to the woodworking tool.

  • Patent number: 4125182
    Abstract: A controller for stopping a punch press when a stock material becomes jammed, includes: translating means for converting the motion of the stock material exiting from the punch press to rotational motion of rotating means which is operatively associated with said translating means, and a movable element, operatively associated with said rotating means. The rotational motion of rotating means produces centrifugal force which keeps the movable element in an operating position. As the stock material buckles or becomes jammed in the press, the motion of the exiting stock material ceases, causing a decrease in and/or subsequently elimination of the angular velocity of the rotating means and therefore a decrease in the magnitude of the centrifugal force. When the centrifugal force diminishes by a predetermined amount or is entirely eliminated, the movable element moves from the operating position to stopping position.

To obtain a maximum possible yield of sheets from such strip, the lengths of the portions between the marks or defects are measured and cut into sheets of two or more different lengths, the cutting being such as to produce the maximum yield of sheets of either or all lengths, singly or in combination, which can be obtained from the length cut. This procedure reduces the loss or waste due to the marks or defects, to a minimum. A special system is provided for this practice and for cutting out the marks or defects between the unmarked strip portions free from defects, with a minimum of loss or waste. Other features are involved.

  • Patent number: 3991639
    Abstract: Apparatus for protecting tools of hydraulically operated fine punch presses of the type having a main piston as well as quick-closing pistons for imparting movement to the press ram. Keying pistons are arranged at the ram in series with and extending in the same direction as the quick-closing pistons to form a keying gap, variable in response to resistance pressure applied to the ram movement at or near the closing operation. A safety stop switch is arranged for detecting the keying gap and for effecting a stoppage of the machine in the event the keying gap is below a predetermined amount indicating an impediment in the path of the ram.

  • Patent number: 3979980
    Abstract: An apparatus and process for protecting a press die and press frame from damage when stock has jammed therein. The apparatus includes a proximity sensor which senses metal entering the press, a proximity sensor to detect the stamped product, and a proximity sensor to detect the skeleton scrap metal left after the stamping. A press cycle detection sensor senses a cycle of the press and generates a timing pulse. Means for comparing signals generated by the proximity sensors is regulated by the timing pulse and includes a signal converter, a memory circuit, a signal comparator and a fault check operatively connected to one another. An output relay breaks the press circuit upon an appropriate signal.The process of protecting a press die includes sensing the input to determine if stock is present, generating an electrical impulse and storing the signal in a memory. The presence of the stamped product and the resultant scrap are noted and similar signals generated. The output signals are also fed to memories.
