Tissue Roll Converting Overview
There are several processes involved in converting parent rolls of tissue into packaged consumer-sized rolls. This module will introduce you to the equipment and processes used to make rolled tissue products including Unwinding, Printing, Embossing, Rewinding, Tail Sealing, Core Making, Log Accumulating, Log Saws, Wrapping, Bundling, Case Packing, Palletizing, and Stretch Wrapping. Converting safety topics are also covered.

Sample Video Transcript
The unwind is the first piece of machinery in the converting line, and its purpose is to unwind parent rolls of tissue and provide an uninterrupted supply of tissue to the rewinder. Some machines have only one unwind stand. So there is a short time period required to change out parent rolls. To provide an uninterrupted supply of tissue to the rewinder, many unwinders have two unwind stands. This allows one roll to be staged and prepared, while the other is being unwound at full speed. When one parent roll is almost depleted, an automatic splicing assembly splices the sheet from the consumed roll to the sheet from a new roll without stopping the machine. Two-ply sheets require two unwind stations to supply both sheets simultaneously. On lines with a printer, a print pattern is imparted to the sheet prior to being laminated in an embosser or rewound in the rewinder.
