Abstract
1330675 Control of paper making apparatus EASTMAN KODAK CO 5 Oct 1970 [3 Oct 1969] 47288/70 Heading G3R In paper-making apparatus, a refiner is adjusted in dependence upon the difference between an actual drying rate i.e. cutting to hydration ratio, and a reference value. In the embodiment shown, the apparatus includes a refiner i.e. jordan 10, a fourdrinier 18, steam driers 22, 24, calendar 26 and take-up roll 28. The position of the plug 14 in the jordan is controlled retroactively through motor 58 by the error between a reference from selector 56 and an actual drying rate per unit temperature (which is proportional to the cutting to hydration ratio of the jordan) as calculated from the moisture loss per unit area, as sensed e.g. by betagauges 32, 34, the paper speed from tachometer 42, the paper width from selector 44, and the temperature dependent pressure of steam in the driers as sensed by diaphragm 46. The signals in the system may be analogue or digital, and the error may operate motor 58 incrementally via a circuit which compensates for the time delay between the jordan and gauges 32, 34. In an alternative, the jordan is manually adjusted according to the error as shown on a meter.
