摘要 |
<p>A sensing system for cut-to-length shear, for providing a shear control signal for a process line of material moving at a line speed which is a function of a voltage VL, the shear control signal being used for causing actuation of the shearing mechanism. A signal VB is derived which is a function of the predetermined cut length. A signal Vi is derived which is a function of the instantaneous length of material passing the shearing mechanism. An additional voltage DELTA V is derived is a function of (VL tinertia/t) where tinertia is the time required for the shearing mechanism to respond to the shear control signal, and t is the running time required for a predetermined cut length to pass through the shearing mechanism at maximum line speed. The signals VB, Vi and DELTA v are received by electronic circuitry, and a shear control signal is delivered to the shearing mechanism when the algebraic relationship is satisfied VB = Vi + DELTA V.</p> |
