Abstract: ABSTRACT OF THE DISCLOSURE           This relates to the handling of thin soft temper material during the feeding thereof and in formation of such material into individual components in a punch press.  Most particularly, a pull tab formed of a plastics material-aluminum foil laminate is being formed.  In order to control the movement of the stock through the punch press, the stock is longitudinally stiffened by the formation of longitudinal ribs therein.  The ribs are preferably formed by the stock feeding mechanism.  The work product is blanked and formed substantially in its entirety in regions of the stock outside of the stiffening rib areas and prior to the final severing of the work product from the stock, the stiffening ribs are flattened.  In the separation of the work product from the stock, there is material removal in a punching operation along the areas previously containing the stiffening ribs.          Feeding of the stock is accomplished by a rotary cam which permits feeding of the stock at all times while the punch elements are disengaged from the stock, thus providing for a longer feed time.  The feed may be selectively less than that provided by the cam by utilizing pivotally mounted feed dogs and a stop which effects pivoting of the dogs and the releasing of the stock while the feed mechanism is still advancing.

Abstract: ABSTRACT OF THE DISCLOSURE The LEL (Lower Explosive Limit) control includes a gas analyzer normally connected to receive sample gas from the evaporation enclosure of a press dryer section and which, during calibration, is sequentially connect-ed to first analyze solvent free gas and then gas having a known solvent content.  Situated with the analyzer is a detector the resistance of which changes in proportion to the temperature within the flame cell of the analyzer.          The detector forms a portion of a bridge circuit, which also includes a potentiometer.  The output of the bridge is amplified, compared to a selected reference voltage and a signal representing the difference there-between is processed.  The processed signal is combined with a signal representing the web speed to form a resultant signal to control a pneumatically operated damper in the enclosure exhaust conduit.  Automatic calibration of the system is initiated periodically and takes place in two phases.  During the first phase of calibration, the potentiometer is set in accordance with the difference between the amplifier output derived from analysis of the solvent free gas and a 0% reference voltage.  During the second phase of calibration, the gain of the bridge output amplifier is set in accordance with the difference between the amplifier output derived from the analysis of the known solvent concentration gas and a full scale reference voltage. When calibration is taking place, the output of the comparison circuit is inhibited and the damper position is determined in accordance with the web speed alone.  Emergency stop of the press occurs when the output of the amplifier exceeds a given level.
