HOW PAPER IS MADE

WASHING AND BEATING

The rags are here washed in clear water which flows in and is carried away continuously. Necessary chemicals are added and the stock is washed white. It then runs into drainer vaults. When ready to be made into paper, the stock is brought up and "beaten" or drawn out further till the required length of fiber is obtained.

THE STUFF CHESTS

From the beaters the stock runs into the stuff chests. There it is mixed by an agitator which looks like the paddles of a big ice cream freezer. This process renders the color uniform. From the stuff chests the stock is pumped over baffle plates and magnets, which remove any sand, bits of iron or similar impurities.
