摘要： A seamless press felt is provided having inner and outer base fabric layers, which can be woven or non-woven, having an MD length and CD width, each including at least a first array of MD oriented yarns and being formed as a continuous unbroken tube structure. An elastic intermediate yarn assembly with parallel and regularly spaced CD yarns, each bonded to an elastic carrier material, is formed as a continuous unbroken tube structure, and is “socked” between the inner and outer base fabric layers. The elastic intermediate yarn assembly has an MD length that is from 1% to 10% less than the MD length of the press felt prior to assembly and is elastically stretched during assembly between the inner and outer base fabric layers. At least one batt layer needled through the inner and outer base fabric layers and the elastic intermediate yarn assembly to fornt he press felt.

摘要： A press felt is provided including a non-woven base fabric material formed of a first fabric structure, with the first fabric structure including an array of MD yarns connected with at least one layer of a hot melt adhesive web material and at least one layer of a non-woven backing. The non-woven backing includes a layer of a first yarn system and a layer of a second yarn system oriented transverse to the first yarn system. At least one of the first and second yarn systems includes a low melt temperature adhesive that is heat activated and binds the first and second yarn systems together. The nonwoven base fabric material has an MD length and CD width and is arranged in two superimposed layers joined by the MD oriented yarns at CD oriented fold regions at each of two opposing ends thereof.

摘要： A seamed press felt formed from a base fabric material including MD yarns arranged in two superimposed layers joined by the MD yarns at CD folds at opposing ends thereof to form a continuous unbroken tube-like structure. The MD yarns form loops at the folds to define a pintle channel. A generally planar yarn assembly including an array of polymeric yarns bonded to an elastic carrier material that is extensible by at least 1% is located inside the base fabric with the yarns of the array oriented in the CD. A high surface contact area material is bonded to the elastic carrier material at both exterior MD ends adjacent to the MD loops at the folds. Each of the MD ends is anchored in a fixed position adjacent to the loops at the folds. A pintle extends through the channel defined by intermeshing the loops from the opposing ends.
