環流量制御装置。 In a paper machine headbox that has a tapered header that tapers in the direction of flow of the raw material, has a plurality of branched outflow pipes arranged on the side of the tapered header, and is equipped with recirculation piping from the taper head, the flow rate of the raw material flowing into the taper head is detection means,
A means for detecting the recirculation flow rate of the raw material in the recirculation pipe, a flow rate control valve for the raw material to the recirculation pipe, and signals from both of the above detection means are used to detect the flow rate of the raw material flowing into the taper head and the recirculation flow rate of the raw material. A recirculation flow rate control device for a paper machine headbox, comprising a device for controlling the flow rate control valve so that the ratio is constant.
