摘要： A headbox employs flow control valves which modulate the flow of stock through each tube of a tube bank, to give greater control over the cross machine direction flow of stock to the forming section of a papermaking machine. In one approach the flow through the tubes making up the tube bank is controlled by rotating cylindrical valve members which extend into portions of the tubes making up the tube bank. The valve members have channels which align with the tubes when the valve is fully opened. Rotation of the control member obstructs the tubes in the column until the desired level of flow from that column of tubes is obtained. In a second approach, pinch valves are created by constructing part of the tube from an elastic material and using air pressure, a cam or a twisting action to reduce the flow through the elastic section thus creating an adjustable valve. A third method employs guillotine valves which selectively block the flow of stock through a column of tubes.

摘要： A graphite composite trailing element for a headbox of a paper making machine is described. A protective layer is provided at or around pondside edges of a trailing element. The protective layer reinforces the pondside edges of the element to protect the edges from damage. The protective layer can also provide a protective sheath around the edges of the element to help prevent stock from being absorbed between the composites making up the elements. With reinforced edges and a protective sheath, the bonded composite sheets of the element are less susceptible to separation and delamination thereby resulting in an improved graphite composite trailing element. The protective layer can be made from any number of woven fiber glass mesh materials and is embedded in an epoxy base. The protective layer is compatible with the bonding and curing requirements of the composite sheets making up the trailing element.

摘要： A headbox tube bank apparatus and method of directing flow through same is disclosed for permitting the flow therethrough of stock in a papermaking machine. The apparatus includes a tube bank frame for rigidly supporting the tube bank, the frame defining a plurality of openings. A plurality of tubes cooperate with the frame such that each tube extends through and is supported by an opening. Each tube has an upstream and a downstream portion, the upstream portion defining an internal cross-machine direction section of substantially circular configuration for maximizing the velocity of the stock through the tube. The downstream portion includes a first and a second end with the first end being connected to the upstream portion and the second end defining a downstream orifice having a flow area in a cross-machine direction which is of rectangular configuration for progressively improving the uniformity, stability, cleanliness, and for lowering turbulence of the stock during flow thereof through the downstream portion.
