Abstract: A size application system and method utilize a plurality of size boxes associated with one or more slashers. A number of size formulation components are mixed and heated at atmospheric pressure to produce a size formulation having a predetermined composition and temperature. The size formulation is pumped in a closed loop past each of the size boxes. The size level in each size box is sensed utilizing a radio transmitter level control in each size box, which utilizes radio waves to sense the level of size in the box. In response to the sensing of the size level by the radio transmitter level control, size formulation is withdrawn from the closed loop through controlled valves, and supplied to each size box having an amount of size therein below a predetermined desired level.

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 The amount of size in each size box is sensed by a level control, and the size formulation is withdrawn from the closed loop and supplied to a size box in response to the level sensing.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 formulation at each size formula station, and mixed with the size formulation prior to introduction into the size box.
