Feeder channel for diluting a fluid, in connection with a headbox of a paper machine includes one or more reservoir-type spaces for receiving diluting fluid. An aperture is formed in the reservoir-type space, wherein the diluting fluid can be conducted into the stock flow space of the headbox. One or more shut-off/adjustment members, for adjusting the flow of diluting fluid, is fitted into the feeder channel. The shut-off/adjustment member is a shut-off/adjustment device that can be moved in the longitudinal direction in the aperture formed in the wall of the reservoir-type space. The shut-off/adjustment member that is partly or wholly inside the aperture with one or more cavities and/or recesses, via which the flow of diluting fluid from the reservoir-type space either directly or via an intermediate piece into the stock flow space can be adjusted by moving the shut-off/adjustment member in the aperture.
