PAPER AND ITS USES
covered wires are dried and the whole coated with some waterproofing non-conductive substance to ensure complete insulation. See Anti-acid Manillas.
Caps.—Thin brown wrappings, used in a variety of trades, fall under this general description.
Carbolic Paper.—Strong packing paper impregnated with carbolic acid, used for packing goods liable to attack by insects or fungi. Carbolic acid being a powerful germicide, and poisonous to insects, acts as protection.
Carbon Paper.—This is a class of paper increasing in use. It consists of a paper with a coating of colour, ground in an oily or waxy medium, applied to one or both sides of the sheet. The pigment, for the black, mauve and blue carbons, is largely composed of lampblack, but other colouring materials are used. The paper is unrolled from the web, the colour applied to the surface, and brushes rub the coating into the paper. Passing over heated and cooled cylinders the paper receives its finish, and is reeled and allowed to mature. Afterwards the paper is cut to special or standard sizes (foolscap folio and large post quarto). By the use of a very thin paper and very thin carbon papers, as many as twetve copies of a typewritten document may be obtained at one time. To make this possible the finest carbons are coated on the thinnest tissue paper procurable. Carbon papers for special purposes include two-sided, greaseless, copyable and hektograph.
Cards.—Pasteboards, ivory boards and pulp boards are cut into cards and put up in packets of 52 and 1,040. Retree cards have the wrappers inside out. Sizes of cards are given on page 140.
Carpet Felt Papers.—Thick, loosely-felted papers, having very little strength. Made of waste papers, grey in colour, used for placing under carpets to prevent marking by floorboards, to give a better feel to the floor covering, and, when impregnated with certain ingredients, to prevent moth infesting the carpet. Made in widths of 54 and 60 inches and sold in rolls of 12 and 25 yards.
Carriage Panels.—A special variety of compressed millboards, afterwards thoroughly waterproofed and used for roofing railway and other carriages.
