Abstract:
A resin-impregnated endless belt for a long nip press or calender of the shoe type has a base fabric in the form of a multilayer braided structure wherein each of the constituent layers are connected to those adjacent thereto by at least one interlocking yarn to inhibit interlayer delamination. The base fabric is in the form of an endless loop, at least the inner surface of which is coated with a polymeric resin material, such as polyurethane. The polymeric resin material impregnates the structure of the base fabric, rendering it impermeable to oil and water.
Abstract:
A modular table filter for a circular horizontal rotating table filter includes a number of sections (20) which may be assembled on the support frame thereof. The sections (20) are annular-sector-shaped and, when assembled, form an annulus on the table filter. Each section (20), in turn, may be broken down into an outer subsection (24) and an inner subsection (22). Filtration fabric (30), or textile, may be placed on top of the outer subsection (24), and secured therein by the inner subsection (22), which is designed to lock therein. Alternatively, each section (20) may be an integral annular-sector-shaped frame having a peripheral groove or channel. Filtration textile (30) may be placed on top of the frame, and over the groove or channel, and wedges driven thereinto to hold the fabric tautly across the frame. The modular table filter greatly simplifies the replacement of the filtration fabric (30), as the sections (20) holding fabric needing replacement may be removed easily and replaced by ones having fresh filtration textiles (30) without the need for isolating the table filter for an inordinately long time.
Abstract:
The present invention is directed towards paper machine clothings comprised of interconnected bicomponent fibers (1, 2). In one embodiment of the invention, the paper machine clothing is comprised entirely of bicomponent fibers in both the machine and cross machine direction. Advantage is taken of the unique bicomponent fiber structure, which permits selection of different materials for the sheath and core components. For instance, the sheath material may have a melting point lower than the melting point of the core material. Accordingly, a fused, bonded structure (5) of bicomponent fibers can be formed where the sheath component has a melting point lower than the core component. By heating a fabric constructed of bicomponent fibers to a temperature greater than the melting point of the sheath component and lower than the melting point of the core component, with subsequent cooling of the fabric to below melt temperature of the sheath component, a fused, bonded structure will result.
Abstract:
A reinforcing member of rebar (10) for use in, for example, reinforcing concrete, comprising a rod member (10) formed from braiding interlocking layers of reinforcing fibers (12) with an enlarged element (16) incorporated into the outer layer to create a surface protrusion (18, 20) to transfer loads from the concrete to the rebar. Resin may also be used with the braided structure to form a composite rebar. A core (342) may also be provided in the rod for reinforcement.
Abstract:
The present invention relates to a fibre structure comprising an assemblage of rigidified or rigidifiable fibres characterised in that said assemblage is provided in at least one surface thereof with a matrix layer of a thermoplastic material which is compatible with said fibres and imparts a substantially continuous surface to said assemblage. In a particular aspect of the present invention a layer of thermoplastic material may be located juxtaposed a shaping surface and the assemblage of fibres capable of shrinking on heating, said shrinkable fibres being clamped about said shaping surface to restrain shrinkage thereof in at least two dimensions and thereafter heating the material whereby the shrinkage forces generated by the fibre assemblage is caused to act against the forming surface thereby to force the fibre structure into the thermoplastic material. The structures in accordance with the present invention have been found to be particularly useful in ducting, tubing conduiting or decorative panels for use in vehicles.
Abstract:
The present invention is an article of paper making machine clothing suitable for use in the forming, pressing or drying sections of a paper making machine wherein the article is comprised of a fibre structure constructed of yarns of expanded poly(tetrafluoro ethylene) ("expanded PTFE").
Abstract:
The present invention is directed towards yarns of covered high modulus filament materials and fabrics which are formed therefrom. The present invention is intended to provide a composite filamentary material which exhibits the advantages of high modulus materials while providing a means for compensating the diminished properties exhibited by such fibers in the direction normal to molecular chain orientation. The composite filament structure of the present invention is a high modulus filament material covered with bicomponent filaments. The composite filament structure has a first interior layer of high modulus filament material and a second exterior layer of bicomponent fibers, the second exterior layer of bicomponent fibers being covered around the first interior layer of high modulus material along its entire length. The entire surface area of the high modulus material should be covered.
Abstract:
The invention concerns a braid structure comprising a plurality of braided layers of stranded material in which said layers are laid down in a single pass of a braiding machine with at least one strand of each layer extending into a contiguous layer to form and interlock between the said layers. The invention also concerns a machine and a method of making the structure by supplying groups of strands (R, B, G, O, W) to a braid forming station whereby each group of strands forms a braid layer thereat; a strand (R) from one of the groups passing into or through the strands (B) of a group of an adjacent layer to form an interlock therebetween.
Abstract:
The present invention relates to a fibrous composition comprising a thermally heat shrinkable fibre structure having in at least a proportion of the structure a substantially homogeneous content of a conducting material sufficient to impart limited conducting properties to the composition.
Abstract:
The invention relates to a laminated clothing for a papermaking or cellulose manufacturing machine, as well as a method and a blank for manufacturing thereof. The clothing comprises two laminated layers (O, I), each having an inclined direction-defined thread system, the thread systems being inclined relative to the machine direction of the clothing and relative to each other. The two layers (O, I) constitute an upper and an inner part, respectively, of an endless band (40), which is so flattened that two edge folds (48, 50) are formed transversely of the machine direction, and which is then doubled with the edge folds (48, 50) coupled together. As a result, the band comprises a direction-defined thread system which is inclined relative to the machine direction and which, owing to the flattening and doubling of the band, forms the thread systems, inclined relative to each other, of the first and the second layer (O, I).
