PAPERMAKING MACHINE WIRE, THE RUNNING SIDE OF WHICH HAS CROSS THREADS WITH DIFFERENT LENGTHS

摘要

A sheet-forming wire with a lower fabric layer formed from a multiplicity of identically constructed lower weave repeats, each of which contains longitudinal threads extending in the lower fabric layer, and lower cross threads, with the lower cross threads extend only in the lower fabric layer. The lower cross threads are tied into the lower fabric layer in each case by exactly two longitudinal threads extending in the lower fabric layer, in that each particular lower cross thread is run under by a first longitudinal thread at a first tying-in point (x) and is run under by a second longitudinal thread at a second tying-in point (x). The lower cross threads form first lower cross threads (I) and second lower cross threads (II). The first lower cross threads form a shorter float on the running side than the second lower cross threads.

formed as a multi-layer fabric having an upper fabric layer and a lower fabric layer which are connected to each other by means of binding threads, wherein the lower fabric layer is formed by a plurality of uniformly structured lower weave repeats, each of which comprising: longitudinal threads extending in the lower fabric layer and lower transverse threads extending exclusively in the lower fabric layer and being interwoven with the longitudinal threads that extend in the lower fabric layer, wherein in the respective lower weave repeat the lower transverse threads are each bound into the lower fabric layer by exactly two longitudinal threads that extend in the lower fabric layer as a first longitudinal thread extends under the respective lower transverse thread at a first binding position and a second longitudinal thread extends under the respective lower transverse thread at a second binding position, and wherein in the respective lower weave repeat the lower transverse threads are bound into the lower fabric layer differently, thereby forming first lower transverse threads and second lower transverse threads, wherein at the first lower transverse threads a shortest distance in transverse direction between the first and the second binding position is larger than at the second lower transverse threads so that the first lower transverse threads form a shorter float on the running side than the second lower transverse threads.
