Abstract
A slitter knife holder has a rod for supporting a slitter knife. Strain gauges are attached to the rod. There is provided a conversion circuit for converting changes in electric resistance of the strain gauges due to the deflection of the rod caused by the pressure of contact of the upper blade with the lower blade of the slitter knife into a signal indicative of the pressure of contact of the upper blade with the lower blade. The signal from the conversion circuit may be applied to a contact pressure monitor for indicating the signal directly to an operator or to an automatic contact-pressure control system.
Claims6
A slitter knife holder apparatus for a slitter knife, the slitter knife including an upper blade and a lower blade, the lower blade being fixed in the direction of the axis of rotation of the lower blade and the upper blade being biased in the direction of the axis of rotation of the upper blade so that an overlapping portion of the upper blade is biased toward an adjacent portion of the lower blade, said slitter knife holder apparatus comprising a rod for supporting the upper blade of the slitter knife, strain gauges attached to the rod and a conversion circuit for converting changes in electric resistance of the strain gauges due to the deflection of the rod caused by the pressure of the upper blade against the lower blade into a signal indicative of said pressure.
