Abstract
The invention relates to paper machine clothing, in particular a press felt for a paper, cardboard or tissue machine, comprising a load absorbing base structure that extends in longitudinal and cross direction of the clothing and which comprises, and in particular is formed by: a) a longitudinal reinforcement module substantially providing the dimensional stability in longitudinal direction of the clothing, and b) a transverse reinforcement module substantially providing the dimensional stability in cross direction of the clothing, whereby the transverse reinforcement module and the longitudinal reinforcement module are arranged one on top of the other and are interconnected with each other. The invention is characterized in that the transverse reinforcement module is a warp knit fabric which is composed of at least one system of weft threads arranged parallel to each other, and at least one system of stitch forming sewing threads which extends substantially perpendicular thereto into which the weft threads are integrated to form a textile fabric, wherein the weft threads extend diagonally to the longitudinal direction of the clothing and have a greater flexural strength than the sewing threads.
