Abstract: A functional roll comprises a shaft body, a roll body, flanges, and bearings. The roll body is formed by stacking multiple module functional rolls. The module functional rolls are formed by stacking multiple nonwoven fabric sheets. The module functional rolls have a bore in which the shaft body is inserted. A module function roll is united.

Abstract: Methods of reinforcing a fibrous roller cladding material, reinforced roller cladding materials and clad lehr rollers wherein the cladding comprises a reinforced fibrous material are disclosed. The roller cladding material, which comprises a fiber board, is reinforced by a method comprising firstly contacting the cladding material with a fluid medium comprising a reinforcing agent whereby fluid is absorbed by the cladding material, and secondly, drying the cladding until the surface of the cladding is dry to the touch, characterized in that the reinforcing agent comprises a compound of phosphorus or a compound of boron. Roller cladding materials reinforced according to the methods disclosed have an improved resistance to cullet damage. The reinforced roller cladding material may be used as the cladding of a clad lehr roller, of the type used for example to convey flat glass in sheet or ribbon form.

Abstract: The invention relates to an exchangeable cylinder jacket-shaped cover made of pile whose threads radially project outward. The aim of the invention is to provide a cover of this type, which has a high cohesive strength both in the axial as well as radial direction and which also has an outer and inner cylindrical contour that is as continuous as possible. To this end, the invention provides that the cover consists of an endless helically wound pile strip whose edges are interconnected by an endless helically running seam without forming a step that disrupts the cylindrical outer contour.

Abstract: A calender roll, which was already in use and has a metallic core with engaged textile material sheets, can be worked for a new use. In the surface of the sheets are cut grooves, to which is subsequently applied a layer structure of synthetic resin-impregnated fibrous material forming a certain thickness over each point of the roll. Onto said layer can be applied a functional covering, for example of rubber.

Abstract: A brush made from a nonwoven, thermally bonded bicomponent fiber web is described. The nonwoven brush of the invention includes a plurality of compressed annular sections assembled about a central carrier with each section made of a mat of bicomponent fibers which have been crimped and melt bonded. In a preferred embodiment, the brush will have a compacted density of between about 50 and about 250 kilograms per cubic meter. The fibers making up the compressed annular sections are preferably a combination of polyolefins (e.g. polypropylene and polyethylene) but may also include polyesters and other materials.

Abstract: The present invention relates to a method and apparatus for forming a longitudinally extending keyway portion in a mill roll having a central bore. The keyway portion may be either a keyway or a tab portion. A cutting head is provided, and includes a body and one or more cutting tools extending from the periphery of the cutting head body. The cutting head is driven through the central bore of the mill roll, and the cutting tools form one or more keyway portions adjacent and communicating with the central bore.

Abstract: A sectional paint roller tube for attachment to a paint roller axle. The roller tube of the present invention has a cylindrical, substantially hollow, endpiece having an opening formed in one end thereof; at least one split sleeve having an inner diameter sized to frictionally engage the paint roller axle and an outer diameter sized to be rotatably received within the endpiece; and a cylindrical, substantially hollow, cap having an opening extending therethrough. One or more extensions may be attached to the endpiece such that an assembled roller tube of a desired length is fabricated. The cap is attached directly to the endpiece if no extensions are utilized, and is attached to the final extension if one or more extensions are used. Thus, by utilizing a small number of standard parts, paint rollers of a wide variety of different lengths are fabricated.

Abstract: A method for forming a longitudinally extending keyway portion in a mill roll having a central bore, in which the keyway portion may be either a keyway or a tab portion. A cutting head is provided, and includes a body and one or more cutting tools extending from the periphery of the cutting head body. The cutting head is driven through the central bore of the mill roll, and the cutting tools form one or more keyway portions adjacent and communicating with the central bore.
