ABSTRACT:
The present invention is a method for coating a plurality of coating compositions onto a moving support while minimizing the time required to switch from one coating composition to a different coating composition. The method involves supplying a first coating composition to a hopper at a first flowrate. When the switch is made to an alternate coating composition, the alternate coating composition is supplied to the hopper at a second flowrate while coating composition is removed from the hopper at a third flowrate equal to the first flowrate subtracted from the second flowrate. After sufficient pumping the alternate coating composition is supplied to the hopper at the first flowrate and no coating composition is removed from the hopper.
