Abstract:
A method of supplying stock to a headbox for injection onto a wire, comprising the steps of:regulating by means of valves a flow of high consistency stock having a consistency of at least 1.5 percent and no more than 4.0 percent into a headbox; simultaneously and separately regulating by valves a flow of dilution water supplied by a dilution pump, into the headbox, so that dilution of the high consistency stock takes place within the headbox to form a diluted stock having a consistency between 0.4 and 1.2 percent; discharging the diluted stock on to the wire; and recovering water which drains from the wire as dilution water which is supplied to the dilution pump, wherein the high-consistency stock flows through a main line to a pump upstream of the headbox, and wherein a component flow is separated from the recovered dilation water, which component flow is added to the main line before the pump.
