Abstract: Disclosed is a method of manufacturing a mechanically and chemically embossed surface covering having selectively textured surfaces. The method includes forming a web coated with a wear layer. The coated web is heated to a temperature at which the wear layer is cured, the foam layer expands, and the pattern is chemically embossed to form a surface covering having foamed regions and nonfoamed regions. The temperature gradient of the surface covering is adjusted such that there is a temperature gradient difference between the foamed and nonfoamed regions. A surface texture is then mechanically embossed into the wear layer and selectively set onto the wear layer substantially overlying the non-foamed regions.

Abstract: An on-machine-seamable papermaker's fabric includes a base fabric having seaming loops at its widthwise edges for joining the papermaker's fabric into endless form on a paper machine. The seam formed when the seaming loops are interdigitated and joined to one another with a pintle is covered with a strip of flow-resistant material, or, where the base fabric is a laminated structure having a top layer and a bottom layer, strips of flow-resistant material are placed between the top and bottom layers adjacent to the seam. The flow-resistant material provides the seam region with permeabilities to air and water substantially identical to those of the rest of the papermaker's fabric. At least one layer of staple fiber batt is entangled through the base fabric and flow-resistant material.

Abstract: A belting (10) reinforced with at least one fabric ply (16). The fabric ply (16) is a composite fabric (26). The fabric (26) has two woven layers (28, 30) and an intermediate third layer of straight warp yarns (34). The woven layers (28, 30) and straight warp yarns (34) are bound together by a plurality of binder yarns (38). Each layer (28, 30, 34) of the fabric (26) contributes substantially 25-40% to the overall strength of the fabric (26). The composite fabric (26) may be used in a multi-ply belting (10) for heavy duty applications; wherein the fabric ply (26) is the center ply (16) and provides approximately 50 to 75% of the overall belting strength. The fabric (26) may also be used as a single reinforcing ply for light duty application belting.

Abstract: An article such as an airfoil that is of light weight and high bending strength, includes a primarily foam core part (20), fibrous strengthening layers (22, 24) at the top and bottom of the core part with the strengthening layers held by threads (64, 72) sewn through the combination, and with resin (32) forced into spaces between the fibers of the strengthening layers and forming smooth surfaces at the top and bottom of the article. The core part includes a thick body (40) of light weight foam (42) and top and bottom reinforcing layers (44, 46) lying against the top and bottom of the body, with the reinforcing layers each having spaces or pores that are filled with foam that is integral with the foam of the body. The moderate strength near the surfaces of the core part, enable the core part to resist crushing of the light weight foam during sewing of the threads and can resist pullout of fasteners that project only partially into the core part.

Abstract: A process for producing a component with an inner fabric includes layering at least two layers of fabric one on top of the other. A layer of plastic in powder form or sheet form is introduced between respective pairs of neighboring layers of fabric. The plastic has a melting point corresponding to at most the melting point and/or the decomposing temperature of the fabric layers. The fabric layers and plastic layer are heated and pressed at a pressure greater than atmospheric pressure, during which the plastic layer is at least partially melted. After reaching the desired final form, the partially-melted plastic is cooled, thereby bonding the fabric layers to one another. The cooled plastic is arranged between the layers of fabric and, in particular, at least partially between the fibers of the fabric layers.
