AUTOMATED SIZING SYSTEM CONTROLLING ABSTRACT Size formulations are supplied to slasher size boxes in an efficient manner allowing nearly unlimited variation in size formulations, minimizing the floor space of size formulation equipment, minimizing energy waste, and providing reclamation of used size. A number of size formulation components are mixed and heated to produce a size formulation having a predetermined composition and temperature. The size formulation is circulated in a closed loop past each of the size boxes. The amount of size in each size box is sensed by a level control, and the size formulation is withdrawn from the closed loop and supplied to a size box in response to the level sensing. A plurality of formula stations are provided, at least one adjacent and in operative communication with each size box, and additional size formulation components are added to the size formula- tion at each size formula station, and mixed with the size formulation prior to introduction into the size box. Heating of the size formulation is accomplished utilizing an interfacial surface generation (ISG) heat exchanger, and mixing at the formula stations is accomplished utilizing an ISG mixer. A single mixing tank, in communication with a holding tank disposed in the closed size formulation recirculating loop, can supply all the size boxes.
