《天工开物·中篇·杀青》
提起抄纸帘，水便从帘眼淋回抄纸槽；然后把帘网翻转，让纸落到木板上，叠积成千上万张。
竹料浮帘之顷，水从四际淋下槽内。然后覆帘，落纸于板上，叠积千万张。
Lift the papermaking screen out of the water, and the water will flow back into the papermaking vat through the holes in the screen; then turn the screen over, let the paper fall onto the wooden board, and stack it up into thousands or even tens of thousands of sheets.
