Introduction to Paper and Board Machines

Paper can be defined as a flat, nonwoven network of cellulose fibers that are bonded together to form a sheet. In the papermaking process, the sheet is formed on a fine-mesh screen from a dilute suspension of fibers in water. This course covers the equipment and processes needed in order to create a fully formed sheet of paper. This includes the forming and press sections, together known as the "wet end" to the "dry end" of the machine where the paper is dried, calendered, and wound onto large rolls of paper called reels. This course also discusses the purpose of the white water and broke collection systems as well as different types of forming and dryer sections that are used in the papermaking process.

•Define the terms "paper," "board," "furnish," "broke," and "white water" •Identify the effect of each section of the paper machine on the sheet being produced •Identify the processes associated with each section of the paper machine •Describe the different types of forming sections, including Fourdrinier, cylinder, paperboard, and twin wire •Describe the dryer sections on multi-cylinder and Yankee machines
