  • Patent number: 5958190
    Abstract: A cleaning apparatus is disclosed for cleaning a forming wire of a paper machine. The apparatus includes a shower which is disposed adjacent to the forming wire for applying a shower of cleaning fluid to the wire. A blow box is disposed closely adjacent to the forming wire and downstream relative to the shower. The box is connected to a source of pressurized air for blowing a jet of air through the wire for removing the cleaning fluid therefrom. A plate is disposed between the box and the wire. The plate defines a plurality of slots which are disposed obliquely to a direction of movement of the wire in order to supply a multiplicity of pressure pulses to the wire for removing contaminants therefrom.

  • Patent number: 5820732
    Abstract: A cleaning apparatus is disclosed for cleaning a forming wire extending around a wire turning roll of a paper machine. The apparatus includes a shower which is disposed upstream relative to the turning roll for spraying a cleaning liquid onto the forming wire. A housing is disposed between the shower and the turning roll, the housing being connected to a source of pressurized air. The housing defines an opening which has a first and a second end. The housing also defines an orifice which has an upstream and a downstream end for permitting a flow therethrough of the pressurized air such that the flow of air is directed against the wire for at least partially removing the cleaning liquid therefrom. The opening cooperates with the turning roll such that the opening conforms with the turning roll for substantially sealing the opening against loss of the pressurized air so that the flow of pressurized air is directed through the orifice.
