Abstract
Abstract 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.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
95 words
A method for manufacturing a composite roll supporting a markable product such as glass, aluminum, brass, copper or steel in a lehr, furnace or oven, said method comprising the steps of providing a rigid cylindrical roll body, preparing a slurry of fibers containing a binder, providing a cylindrical screen member, depositing the slurry of fibers on said screen member by radial movement of said slurry whereby the fibers interlace themselves and are built up to form a sleeve of a desired thickness, and mounting and securing the sleeve about the circumference of the roll body.
Claim 2
Independent Claim
95 words
A method for manufacturing a composite roll supporting a markable product such as glass, aluminum, brass, copper or steel in a lehr, furnace or oven, said method comprising the steps of providing a rigid cylindrical roll body, preparing a slurry of fibers containing a binder, providing a cylindrical screen member, depositing the slurry of fibers on said screen member by radial movement of said slurry whereby the fibers interlace themselves and are built up to form a sleeve of a desired thickness, and mounting and securing the sleeve about the circumference of the roll body.
Claim 3
Dependent Claim
20 words
The method according to claim 1, in which the sleeve is dried before it is mounted on the roll body.
Claim 4
Dependent Claim
27 words
The method according to claim 1, in which the sleeve is removed from said screen member while still wet and mounted on the roll body to dry.
Claim 5
Dependent Claim
24 words
The method according to claim 1, with the further step of subjecting the sleeve to a wet rolling operation to provide densification and concentricity.
Claim 6
Dependent Claim
34 words
The method according to claim 1, in which the screen member has an outside diameter approximating the diameter of the roll body and the fibers are deposited on the outside of the screen member.
Claim 7
Dependent Claim
27 words
The method according to claim 1, in which the sleeve is formed on the inside of the screen member to provide maximum density to the outside fibers.
Claim 8
Dependent Claim
31 words
The method according to claim 1, in which the screen member is left in place on the inside of the sleeve and placed on the roll body as a reinforcing element.
Claim 9
Dependent Claim
30 words
The method according to claim 1, in which the radial deposition is accomplished by means of a pressure differential maintained between the slurry and the other side of the screen.
Claim 10
Dependent Claim
29 words
The method according to claim 1, in which the slurry is propelled against the screen member with sufficient velocity to accomplish the interlacing and building up of the fibers.
Claim 11
Dependent Claim
14 words
The method according to claim 1, in which the slurry comprises a gaseous fluid.
Claim 12
Independent Claim
104 words
A method for manufacturing a composite roll useful for supporting a markable product such as glass, aluminum, brass, copper or steel in a lehr, furnace or oven, said method comprising the steps of providing a rigid cylindrical roll body, preparing a slurry of fibers containing a binder, placing a cylindrical screen in said slurry having an outside diameter approximating the diameter of said roll body, creating a vacuum inside said screen whereby the fibers are caused to interlace themselves on the screen to a desired thickness, drying the sleeve thus created, and mounting and securing the sleeve about the circumference of the roll body.
Claim 13
Independent Claim
104 words
A method for manufacturing a composite roll useful for supporting a markable product such as glass, aluminum, brass, copper or steel in a lehr, furnace or oven, said method comprising the steps of providing a rigid cylindrical roll body, preparing a slurry of fibers containing a binder, placing a cylindrical screen in said slurry having an outside diameter approximating the diameter of said roll body, creating a vacuum inside said screen whereby the fibers are caused to interlace themselves on the screen to a desired thickness, drying the sleeve thus created, and mounting and securing the sleeve about the circumference of the roll body.
Claim 14
Dependent Claim
30 words
The method according to claim 11, said method also including the steps of tailoring the slurry concentration to obtain concentric layers of material in said sleeve of varying fiber concentrations.
Claim 15
Dependent Claim
18 words
The method according to claim 11, including the further step of machining the outer surface of said sleeve.
