World's Most CompletelY Automqted Fiberboeird Mqnufocturing Focility

Opened by Celotex CorP. ql L'Anse

Ofrcial opening of The Celotex Corporation's new insulating fiberboard plant at L'Anse, Michigan, took place September 23, 24 and,25, according to Henry W. Collins, president, who said the plant, manag:ed by Franz J. Alfeis, is the world's most completely automated and mechanized fiberboard manufacturing facility. The plant has a daily capacity of 500,000 square feet of one-half inch fiberboard and will increase Celotex fiberboard production capacity about 25Vo. It produces such products as acoustical and decorative ceiling tile, insulating sheathing, insulating roof deck, and roof insulation.

To provide the plant with its daily diet of approximately 175 tons of wood, Celotex owns 185,000 acres of forest land in Baraga and surrounding counties and has perpetual timber cutting rights to an additional 57,000 acres. Through scientific forest management, these timber lands will provide a continuing supply of pulpwood, the plant's most important raw material.

A specially desigrred system of intricate, automatic controls assures production efEciency and product quality by guiding plant operations from the wood yard, where raw material arrives by train and truck, through board manufacture and final fabrication. Pneumatic controls, unique to the L'Anse plant, accurately regu-

Charactistics of the wet board produced are varied from the low density of acoustical ceiling tile to the comparatively higher density of Strong-Wall insulating sheathing.

A dual refining system permits the mixture of different grades of wood, even allowing hardwoods and softwoods to be used simultaneously. In itself, the use of dense hardwoods, such as maple and birch, in the production of flberboard is a relatively new process. Indications are that eventually 60ck or more of total wood used at L'Anse may be dense hardwoods'

From a single plant with 34 employes, Celotex has expanded in four decades to a network of 11 plants and 17 district sales offices serving all parts of the United States. A plant in London, England' (Celotex, Ltd.) produces a wide variety of hardboard and fiber. board products.

For commercial installation, Celotex markets the well known line of Acousti-Celotex acoustical ceiling tile and suspension systems including economical fiberboard tiles, incombustible mineral fiber panels amd efrcient steel-base sound-absorbing tiles. In three plants covering important market areas across the country' the firm manufactures asphalt shingles, roll roofing and asphalt roofing felts.

Celotex is also a major manufacturer and supplier of Celo-Rok gJrpsum wall-board, sheathing, lath and plaster; mineral wool insulating blankets and Handi-Pak home insulation; insulating siding; decorative interior hardboard panels and exterior hardboard siding; and industrial fiberboard for a wide range of other applications such as packaging of delicate or irregularly shaped items and as a component of other products'

Production start-up at the L'Anse plart marked the completion of a major four-year expansion progTam. Included in the program were a $6 million gypsum products plant at Ft. Dodge, Iowa; a g3 million mineral fiber ceiling tile facility at Pittston, Pennsylvania; a new Research Center in the Chicago suburb of Des Plaines, and major modifications at the Marrero plant'

There are over 23,000 people with an annual payroll exceeding $120 million directly dependent on the forest products industries of the Redwood Region. The forest industries are aiming for perpetual production, but preventing man-caused forest fires is not their job alone everyone must work to "Keep the Redwood Region Green."
