A roll cover is made by preparing a slurry of fibers and radially depositing these fibers on a cylindrical member such as a screen, building up a sleeve which may be mounted on a mandrel. The concentration of fibers in the slurry may be tailored to suit requirements, so that a sleeve may be formed with fiber concentrations which vary in a radial direction.

BACKGROUND OF THE INVENTION BRIEF SUMMARY OF THE INVENTION It is the general object of the invention to provide a novel and improved roll for carrying markable prod-- 'ucts through lehrs, furnaces or ovens, and a method of manufacturing such a roll which permits the use of materials other than asbestos. 7
It is another object to provide. an improved method of this nature which permits various rolls to be made with properties best suited for their particular applications. v
Briefly, the construction of this invention comprises a cylindrical body and a sleeve of pressure formed fibrous material The sleeve'may be formed of ceramic fiber or mixtures of ceramic and metallic wool materials. One method of this invention comprises making a slurry of fibers containing various inorganic or organic binders, placing a cylindrical screen in the slurry and creating a vacuum within the screen so that the fibers in the slurry are deposited thereon and interlace themselves to build up to any desired thickness. The tubular section so manufactured can be mounted on the roll body without any significant axial compression to accomplish an equivalent or improved result as compared with asbestos covered rolls. Thefiber concentration in the slurry may be varied during the course of deposition to create sleeves with various fiber densitiesor with densities which vary in a radial direction.
BRIEF DESCRIPTION OF THE DRAWINGS The FIGURE shows a roll carrying a vacuum deposited sleeve made according to the invention.
DESCRIPTION OF THE IREFERRED EMBODIMENT The roll is generally indicated at 11 and comprises a body 12 of cylindrical shape which may be of steel, stainless steel or other suitable material. Mounted on this body is a sleeve generally indicated at 13. The ma terial of this sleeve may be ceramic fibers suchas Kaowool manufactured by Babcock & Wilcox Company, Fiberfrax manufactured by Carborundum Company, quartz, amorphous silica, mineral wool, glass, or metallic wools. Alternatively, these fibers may be mixed with metallic wool for strength and resiliency. Sleeve 13 may be secured to body 12 by any suitable means such as a bonding adhesive, pins, keys, collars or set screws. Sleeve 13' may be made up of axially adjacent. sections instead of as one continuous member.
One method of manufacture of sleeve 13 is as follows: A slurry is prepared of fibers and various inorganic or organic binders. A cylindrical screen having an outside diameter approximating the diameter of body 12 is placed in this slurry of fibers. A vacuum is created inside the screen so that the fibers are deposited on the screen and interlace themselves, being built up to any desired thickness. After the proper thickness is attained, the screen is removed from the slurry and the sleeve allowed to dry. Alternately, the fibrous tubular section can be removed while wet and allowed to dry on another mandrel or the roll mandrel. The outside surface of the sleeve may be machined if desired, or could be mounted on the body without subsequent machining. The latter construction would minimize marking and make less critical any out-of-round condition of the parts. I
If desired, the slurry concentration could be tailored to create concentric discrete zones .of varying fiber concentration. For example, zone 14 adjacent body 12 could have a fiber mix which has superior resiliency to take up radial expansion of body 12 when it is subjectedto heat during operation. Intermediate zone 15 could have a fiber mix with the desired insulating value and nominal strength. The fiber mix of outer zone 16 could provide strength, insulative qualities and abrasion and scratching resistance. The sleeve may alternately be formed by other methods of radial deposition of the slurry fibers. For example, instead of creating a vacuum inside the screen, pressure could be applied to the slurry, so that the pressure differential causes deposition. The fibrous material could be propelled against the screen with sufficient velocity to accomplish interlacing and bonding, for example by air deposition or gunning. The slurry could, in other words, comprise a gaseous fluid.
After the sleeve has been formed by any of the above methods, it could be subjected to a subsequent wet rolling operation to provide densification and concentricity.
sleeve on the inside of a tubular screen to provide maximum density to the outer fibers.
In some cases, the cylindrical screen could be left in place as a reinforcing element when the sleeve is mounted on the roll mandrel.
I claim: I
