A fibrous structure. The structure includes a plurality of semi-continuous knuckles extending from portions of the surface of the fibrous structure in a parallel path, wherein the plurality of semi-continuous knuckles are separated by adjacent semi-continuous pillow regions. Each semi-continuous knuckle comprises a plurality of discrete pillows, the plurality of discrete pillows are arranged in a spaced configuration along the path of each of the semi-continuous knuckle.

A process of determining features of a fabric. A representation of a portion of a surface of the fabric is formed showing at least one of (i) locations and (ii) sizes of knuckles and pockets in the surface of the fabric. An image is generated of the portion of the surface of the fabric based on the representation. A portion of the image is displayed on a computer screen. An outline is drawn around at least one of the knuckles in the image. Guidelines are drawn such that the guidelines (i) pass through the center of the at least one outlined knuckle, (ii) pass through the other knuckles, or (iii) form shapes that surround areas of the image that correspond to where the pockets are formed between the knuckles. The outline and the guidelines are drawn using an image analysis program.

A process of analyzing wear on a papermaking fabric includes forming a first representation of a portion of a surface of the fabric showing locations and sizes of knuckles and pockets in the surface of the fabric. A first image is generated based on the first representation. At least one characteristic related to the surface of the fabric is determined using the first image. The fabric is worn. A second representation of a portion of the surface of the fabric is formed showing locations and sizes of knuckles and pockets in the surface of the fabric. A second image of the knuckles of the fabric is generated based on the second representation. At least one characteristic related to the surface of the fabric is determined using the second image. The determining steps are performed using an image analysis program stored in a non-transitory computer readable medium.

An endless fabric belt for use in a paper, cardboard or tissue machine has machine-direction threads and cross-machine-direction threads. At least part of the threads are yarns composed substantially of a thermoplastic polymer material which is transparent for light of a wavelength. The fabric belt is a flat-weave with two front-side ends that are subsequently connected by bringing together end sections of the machine-direction threads in pairs with the formation of junction points and are woven with cross-machine-direction threads, forming a seam region. A material-to-material bond is formed in the seam region by absorbing light at the wavelength at yarn contact points. In the seam region, a plurality of spaced-apart, strip-shaped fabric sections are formed, in which the junction points and the yarn contact points which are connected to one another are arranged, and one strip-shaped fabric section without junction points is formed between two immediately adjacent fabric sections having the junction points.

An industrial fabric that includes: an upper surface side fabric including upper surface side warps and upper surface side wefts; a lower surface side fabric including lower surface side warps and lower surface side wefts; and binding warps that bind the upper surface side fabric and the lower surface side fabric and that constitute a portion of the upper surface side fabric and a portion of the lower surface side fabric, includes: first warp pairs that are each formed by a pair of binding warps that are vertically adjacent to each other; and second warp pairs that are formed by the upper surface side warps and the lower surface side warps that are vertically adjacent to each other.

An acoustical tile including: 8 to 25 wt % mineral wool, 9 to 15 wt % starch binder, 9 to 15 wt % cellulosic fiber, wherein preferably the cellulosic fiber is newsprint, and 40 to 65 wt % perlite, wherein the weight ratio of the starch to the cellulosic fiber is 0.6 to 1.3:1; and a process for making the acoustical tile.

A method for operably adjusting a forming board lead blade of a paper sheet forming machine of the type having a headbox for impinging a jet of slurry from a slice opening of the headbox onto the surface of a porous wire moving continuously in a horizontal machine direction over the forming board.

A continuous papermaking machine including a headbox for discharging a suspension of cellulose fibers in water, a forming wire moving in a process direction, the forming wire receiving the suspension from the headbox such that a web is formed on the forming wire, a top former above the forming wire for upwardly removing water from the web, the top former comprising a lead out roll, a dewatering device below the forming wire and downstream from the top former, and an applicator positioned above the forming wire and downstream from the lead out roll of the top former, the applicator discharging onto the web a mixture that includes microfibrillated cellulose and a carrier.
