The Dry End refers to the final section of a paper making machine where the paper is dried, finished, and prepared for shipping. It's like the last stage of a production line where the paper gets its final shape and qualities. This area is crucial because it determines the paper's final characteristics such as smoothness, thickness, and moisture content. Think of it as similar to the final preparation area in a bakery, where bread gets its final texture and is packaged. The term is common in paper mills and is essential knowledge for anyone working in paper production.
