Abstract (en)

[origin: EP0408849A2] 1.1. The invention concerns a forming fabric for the wet end of a paper machine, consisting of at least two complete woven fabrics of any desired type of weave which are held together by longitudinally and/or transversely orientated binding threads, the longitudinal threads of the fabrics forming longitudinally orientated fibre support points and the transverse threads forming transversely orientated fibre support points. <??>1.2. To adapt the surface structure of the paper to the particular intended use with the aid of fabric construction means without altering the character of the basic fabric construction, it is proposed that at least some of the longitudinal threads and/or transverse threads of the forming fabric be partnered by threads which in at least one repeat are parallel to and hence follow the same method of interlacing as the particular longitudinal and/or transverse threads and to alter the numerical ratio of the longitudinally orientated fibre support points to the transversely orientated fibre support points of the forming fabric. <IMAGE>
