Abstract: A wrapping paper for a roll having two opposed roll ends, the wrapping paper includes: a paper layer; and at least one exposed strip having adhesive properties. The at least one exposed strip is proximate to a side edge of the paper layer and covers at least a portion of one of the roll ends when wrapped around the roll. A method for wrapping a roll having a pair of spaced roll ends and an outer roll surface extending between the roll ends.

Abstract: A packaging for a roll of material, such as a roll of paper, having a cylindrical wall and opposing ends. The packaging comprises a wrapper to be wound about the cylindrical wall of the roll, the wrapper being sized to extend beyond the opposing ends of the roll for folding and crimping extending edges of the wrapper onto said opposing ends; and at least one header to be fitted against the respective ends of the roll and comprising an embossed cellulosic substrate to absorb a volume of crimps when the wrapper is folded and crimped onto the ends and pressure is applied against the ends of the roll. It also relates to a method and a packaging kit for packaging a roll of material, a packaged roll of material, and a packaging header.

Abstract: A wrapper for wrapping on a roll of length L having two opposed roll ends is described. The wrapper comprises an interior layer of a length Wi and of an interior layer basis weight, adapted to be adjacent the roll when the wrapper is wrapped on the roll; an exterior layer of a length We longer than the length Wi of the interior layer forming at least one end strip of width S and of an exterior layer basis weight, adapted to be outside of the roll when the wrapper is wrapped on the roll. The interior layer basis weight is different from the exterior layer basis weight. The end strip of the exterior layer is adapted to be folded on a corresponding one of the roll ends during crimping following wrapping of the wrapper on the roll.

Abstract: A water-repellant and gas barrier composite material includes a core portion and a face member mounted to one of the surfaces of the core portion. The core portion has a wood fiber based geometrically patterned structure defining two spaced-apart substantially planar surfaces and including an hydrophobic additive. The face member has a wood fiber based linerboard including an hydrophobic additive and a nylon coating film on a surface of the wood fiber based linerboard.

Abstract: An integral tandem bearing assembly for supporting a main shaft in a gas turbine engine is provided. The tandem bearing assembly comprises two bearing assemblies connected by integrated inner ring.

Abstract: The present invention relates to a light reflective and insulating paperboard honeycomb material that can be used for packaging applications. The material comprises a core portion including a honeycomb material having two faces and two face members. Each face member has an inner surface and an outer surface. Each inner surface is laminated on a respective face of the core portion and at least one of the outer surfaces is light color. It also relates to a method to manufacture the light reflective and insulating paperboard honeycomb material and a container manufactured with the latter.

Abstract: The present invention relates to repulpable wrappers comprising water-activatable adhesive(s). The present invention is also concerned with methods for wrapping a master roll of paper manufactured in a paper-maker plant. The present invention is also concerned with a master roll of paper wrapped with a wrapper having a water-activated adhesive. The wrappers of the invention are fully recyclable and fully repulpable. They are also less sensitive to blocking than regular commonly used wrappers. The methods for wrapping master rolls of paper according to the invention are more effective and much more environmentally friendly than the methods actually used in the industry.

Abstract: This invention relates to a mulch having a preprogrammed biodegradability comprising at least two different layers of biodegradable polymer coated onto a sheet of a cellulosic material, one of these layers being a layer of polylactide. The mulch is particularly useful to control weeds in agriculture, horticulture, and forestry industries. The biodegradability of the mulch can further be preprogrammed according to the type of soil, the climatological zone, and the specific applications wherefore it is intended to be used. The present invention is also directed to methods for preparing and using the multilayer coated mulch.

Abstract: The mulch comprises a sheet of paper having a thickness between 2 and 4 mils and a basis weight between about 40 g/m.sup.2 and 60 g/m.sup.2. The sheet has at least one face coated with a layer of polylactide, which is used in an amount such that it weighs between about 2 g/m.sup.2 and 15 g/m.sup.2. The preparation is carried out by depositing on the sheet an amount of a hot extruded liquid layer of polylactide such that when it solidifies, it weighs between about 2 g/m.sup.2 and 15 g/m.sup.2, and allowing the layer to solidify and adhere to the sheet, whereby forming the mulch.

Abstract: An insulating material is described and comprised of loose fill short cellulose fibers and bonding synthetic fibers. The synthetic fibers are of longer length than the short cellulosic fibers and have an outer sheath which is heat-fused with outer sheaths of other synthetic fibers at crossing contact points thereof to form a matrix having pockets for retaining the loose fill cellulosic fibers therein and throughout the matrix thereby eliminating the need of an adhesive binder to retain the cellulose fibers in the matrix. The matrix can form a body having the shape of a batt of insulation and the batt may be provided with a facing sheet of suitable vapor permeability.
