Patent ID: 8444825

Claim:
Single or multilayered forming sieve for the wet end-section of a paper machine with upper machine-direction, MD, and cross-machine-direction, CMD, threads facing the paper side, and lower MD and CMD threads facing the machine, characterized in that: at least the paper-side thread floats and knuckles ( 10 ) are reshaped by means of one or a combination of temperature, pressure and/or moisture and as a result of the thread inflection regions being reshaped, the reshaping causing the paper-side knuckles to have a width greater than the diameter of the remainder of the threads, the void size lying between the threads ( 13 ) is reduced by between 1% and 15% from the original void size prior to inflection region reshaping; wherein the width of the thread floats and knuckles ( 10 ) is greater than the diameter of the remainder of the thread ( 13 ), by between 5% and 15%.
