摘要： A device and a method for producing a pulp web in which the first clothing and the second clothing are wrapped partly round the forming roll and another roll. The pulp web formed is guided between the forming roll and the other roll on the first clothing and the second clothing is guided separately from the first clothing, at least in one section. This enables the pulp web to be produced with low energy consumption and operating costs.

摘要： 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.

摘要： The invention disclosed herein relates to the use of laser energy to weld or melt selected locations in papermachine clothing (“PMC”) and other industrial and engineered fabrics. The invention also relates to an improved seam for a papermaker or other industrial fabric that has properties such as strength, durability, openness, adequate number of support points, and fiber support index (FSI) essentially the same as the fabric body. The invention also relates to a fabric having a durable seam, wherein the seam width as measured in the MD is a fraction of the width of a normal seam or a seam that is formed using a conventional technique of equal strength.
