  • Patent number: 5864931
    Abstract: A felt, especially for the press part of a papermaking machine, comprises at least one support belt and at least one fiber belt deposited on and affixed to it. In order to impart to such a felt improved operational properties while retaining adequate transverse stability and in order to manufacture it at substantially lower cost, the support belt(s) 45, 50, 57, 58, 64, 71, 72 each are composed of at least one support-belt strip 46, 51, 52, 59, 60, 65, 66, 73, 74, 75 with a width less than that of the support belt(s) 45, 50, 57, 58, 64, 71, 72 , said strip(s) being continuously wound essentially in the direction of advance of the felt 42, 47, 53, 61, 67 and also spirally transverse to it.
    Type: Grant

  • Patent number: 5465764
    Abstract: A dryer screen has a paper side and a machine side. A plurality of machine direction threads extend in the direction of movement of the screen. The machine direction threads are arrayed in first and second groups. The threads of the groups are bound to the screen through different binding pattern repeats. A plurality of cross threads extend generally transverse to the machine direction threads. The threads of the first group are arrayed in first and second subgroups offset with respect to the direction of movement of the screen. Each subgroup comprises at least two abutting contiguous machine direction threads having a binding pattern repeat floating on the paper side over a predetermined plurality of cross threads.

  • Patent number: 5204171
    Abstract: The invention concerns a press felt for the pressing region of a papermaking machine and comprises a belt of support material made of one or more fabrics or knits and one layer of fibers deposited at least on the paper side and connected to the belt of support material, the surface of this layer of fibers forming the paper contact-side and a permeable layer being mounted in said layer of fibers between the paper contact-side and the belt of support material. To improve dehydration, the permeable layer is designed to be a blocking layer 7 with a surface covering of 45 to 85%, the blocking layer 7 comprising transverse, elongated passages 9.

  • Patent number: 4775446
    Abstract: A joinable paper machine felt assembly includes a plurality of spaced first and second cross-threads, the cross-threads being longitudinally spaced and each first cross-thread being laterally spaced from a second cross-thread for thereby defining a plurality of cross-thread pairs. An end two of the cross-thread pairs define first and second fabric ends. A plurality of first and second alternatingly disposed and directly adjacently positioned lengthwise threads bind the cross-threads into a fabric. Each first lengthwise thread forms a first loop extending over the threads of the cross-thread pair at one of the fabric ends and immediately thereafter each first lengthwise thread extends back into the fabric and alternatingly first crossing between and then passing over the associated cross-threads of the cross-thread pairs.
