Abstract

PURPOSE: To improve the controllability of a profile at both edges of a slice lip by calculating the accumulated values of the deviation of the profiles at the neighbors of both the edges of the slice lip, and changing the set value of a pressure controller of a no-deckle shower when the calculated value exceeds a dead zone. CONSTITUTION: This profile controller of basis weights having a mechanism for outputting the result calculated based on the deviation between a measured signal of the basis weight profile from each measuring point of a slice lip, and a set signal of the basis weight profile, as a signal to each slice bolt as an operating terminal corresponding to each measured point, and a means for regulating the pressure of a no-deckle shower installed at both the ends of a head box, has a means for calculating an accumulated value of the deviations at plural measuring points at the neighbor of both the ends of the slice lip, and a means for changing the set value of the pressure-regulating means of the no-deckle shower when the calculated value exceeds a dead zone.
