ABSTRACT:
A binder applicator for applying binder to a moving substrate includes a distribution pipe extending transverse to the direction of movement of the substrate, with the distribution pipe having a bottom provided with a discharge opening. A distributor channel receives liquid binder from the discharge opening and directs the liquid binder upward. A horizontal reservoir receives the liquid binder material from the distributor channel, and a weir meters the discharge of the binder from the horizontal reservoir to form a thin horizontal flow of liquid binder material. A curved surface receives the thin flow of binder material and gradually changes the flow path to a substantially vertical thin flow of binder material for discharge onto the moving substrate.
