Langston Corrugating Machine
Double-faced corrugated paper consists of the corrugated stock and two flat liners, one attached to each side of the stock. The double-face board is stronger than any other board of the same weight, and it also serves as a cushion whenever anything comes in contact with it. This board is made of various kinds of stock, including strawboard, news and chip, and the facing is also of various kinds of strong paper. From double-face corrugated paper a great variety of paper boxes, shipping containers, etc., are constructed. It is also used for partitions, liners, padding, picture backing, and as protecting boards for mailing printed matter, photographs, etc.
The Samuel M. Langston Co., of Camden, N. J., is a large manufacturer of all kinds of machinery for making the corrugated board and its products. The Langston corrugating machine for single-faced corrugated paper is designed to make the single-faced paper, complete, in big rolls of 250 feet each. The corrugation is formed on this machine under pressure. Adhesive sodium silicate is applied to the tops of the corrugated paper while it is in the corrugating roll, and the lining sheet, tempered over a steam-heated roll, is stuck to the corrugated sheet under pressure. The machine is equipped with a steam roll for moistening and heating the straw sheet before it enters the corrugating roll.
The Langston combined corrugator and double-facing machine takes three rolls of paper and produces in continuous operation double-faced corrugated board, cut into sheets, trimmed, and scored one way, if desired. It is equipped with a “Duplex” cutter, making it possible to run two separate orders, each of a different width and length, side by side.
Adhesive sodium silicate, such as that used in the construction of corrugated paper, taping, etc., is supplied by the Central Commercial Co., of Chicago, or the Grasselli Chemical Co., of Cleveland, O.
