Japanese Patent JPS5257201
Kind Code:
Y2
Abstract:
A paper making machine having a substantially horizontal fourdrinier wire supported on a breast roll and a headbox includes a slice lip construction for shortening and controlling the trajectory of stock emerging from the headbox slice by deflecting the stock stream downwardly against the wire and changing the deflection with change in size of slice opening to maintain an optimum slice strain angle relative to the wire. One form of headbox has an elongate thin tapered slice chamber with the top wall and a bottom wall leading to a slice opening with the slice chamber inclined upwardly and the slice lip construction is positioned to direct the trajectory of stock onto the wire.
