Converting Machines

Converting machines are used for cutting and packaging large production materials, usually roll stock, into smaller, more usable shape and sizes. Converting equipment includes rewinders, slitters, and sheeters, and can also convert roll stock to sheet stock. Converting machines are categorized by the type and size of the original material, the processing speed, and the configuration and size of the output material. Output material is also often packaged in boxes, cartons, or pallets for shipping and distribution.

Converting machines are used to convert all kinds of products to smaller sizes and shapes, including paper, film, foam, felt, polyester, and tissue-based products. Some converting machines also configure products with tapered or glued edges, or perforate and laminate particular materials. Paper converting machines include slitting, sheeting, and rewinding machinery that cut and shape rolls of paper for use in various paper applications. Other types of paper converting machinery include corrugating machines and box-making machines, which take raw paper stock and through a series of integrated machine units, can cut, fold, glue, and print cardboard boxes.

Web converting machinery converts roll stock to other configurations and involves using slitting, unwinding, and rewinding machines. A slitter is a converting machine that cuts a large roll of material and rewinds the material into smaller individual rolls. These web converting machines may also apply glue to one side, such as in the manufacturer of tape or self-adhesive labels. Another type of web converting machine is a rewinding or doctoring machine, which can salvage a poorly-wound roll of stock by unwinding and rewinding it, rather than scrapping the material. Web converting machines can be used on paper and film as well as other kinds of materials, including plastics, laminates, fabrics, and vinyl. Manufacturers of converting machines are located across the United States and around the world.
