Abstract: 423,661. Emery and sand cloth and paper. STEVENS, A. H., 5, Quality Court, Chancery Lane, London.-(Minnesota Mining & Manufacturing Co. ; 791, Forest Street, St. Paul, Minnesota, U.S.A.) June 6, 1933, No. 16247. [Class 60] In the manufacture of sand paper, emery cloth, and like abrasive articles, the binder is applied in an unfused condition and rendered adhesive in place, as by heating, and is then cooled to solidify it to a flexible and waterproof state. Substances which may be used as binders are resins such as shellac, copal, dammar, elemi, abietic anhydride, or mixtures of these together or with other substances, synthetic resins such as alkyd resins or that sold under the Registered Trade Mark " Glyptal," esters resulting from the reaction of phthalic anhydride with either ethylene glycol or glycerol, or condensation products such as phenol aldehyde or urea aldehyde. Modifying agents may be added such as diethyl, dibutyl and diamyl phthalate, dicresyl and tricresyl phosphates and triphenyl phosphate, camphor, benzoin and cellulose acetate, castor oil, vegetable oils, plasticizers known in the lacquer art, gums, resins, cellulose esters and rubber. The abrasive and binder may be mixed before application, 8 per cent by weight of the ester of ethylene glycol and phthalic anhydride and 12 per cent of diethyl phthalate being mixed with the abrasive. A strip 9 passes from a roll 10 over an idler 11, preferably heated, and then beneath a vat 8 from which the binder and abrasive are discharged in a finely divided unfused condition. A heater 13 renders the binder substantially fluid, and the strip is then allowed to cool over the distance 14 before passing over a roller 12 which applies coating material from a container 15, which may be heated, to the strip. Resins or plasticizers may be applied to the reverse side of the strip, while the strip may be pretreated with a solution of vegetable oil or wax. A blower 16 may cool the coated material. Free abrasive may fall by gravity from the strip between the rolls 17, 18, or may be detached by a beater 19. The paper may be used in operations such as sanding lacquered surfaces where a wetting agent such as water, hydrocarbon mixtures with water, and hydrocarbons such as gasoline and kerosene is used.

A method of manufacturing a two-ply flexible wood veneer panel for covering surfaces comprises covering a surface of a first veneer with an adhesive which is bonded to a second veneer with grains crossed under pressure and heat so as to ensure gluing over the entire opposed surfaces of the two veneers, the resulting panel being flexible in both directions, and choosing the thickness of each veneer, the moisture content of the veneers before bonding, and the bonding time so as to prevent the generation of stresses caused by swelling of the veneers and shrinkage of the glue or to have these stresses approximately cancel one another, whereby after bonding the panel is substantially flat. The veneers may be of beech wood 1 to 2 mm. thick and have a moisture content which is first reduced and then raised to between 6 and 12% before bonding. After bonding for a time between a few seconds and five minutes and at a temperature of over 100‹ C., preferably 120‹ C., the moisture content is between 5 and 12% and may be less than 5%. The adhesive may be a urea resin glue containing water, a phenol resin glue, or a heat fusion adhesive. The two-ply panel may be cooled to 80‹ C. after pressing. The panel may be used to cover walls, floors or ceilings and may have a transparent protective coating of synthetic plastic. The panel may have its moisture content raised to 8 to 12% before application to the wall &c. Methods of determining the desired moisture content and bonding time are described.
