Title:
【発明の名称】段ボール用ライナウエブの形成装置
Document Type and Number:
Japanese Patent JP3087224
Kind Code:
B2
Abstract:
In a twin wire former a headbox injects stock onto a forming wire with which a second forming wire is brought into gradual engagement. A forming shoe directs the two wires along a path of increasing curvature, above which water is drained by adjustable auto slices. The two wires with the web therebetween then follow an oscillating S-shaped path between seven S-rolls and are directed upwardly through three individually loaded press rolls with increasing pressure to about four hundred and fifty pounds per linear inch at the last wet press. Drainage pans collect water from the upper surface of the twin wires and water thrown off the upper press rolls. The press rolls are individually pneumatically pivotable to increase nip pressure, and collectively pivotable to open all the nips. Next a high pressure dry nip can increase the fiber content of the web to thirty-five percent fiber.
