or wrinkles occur during application of the helix type path the adjacent path segments form coating segments 4 a 4 d which are known from fig3 whereby adjacent coating segments 4 a 4 d overlap respectively in an overlap region 11 a 11 c the solid line in fig4 represents the contact edge between adjacent coating segments 4 a 4 d on the paper side of coating 4 the respective overlap region 11 a 11 c extends then always from the solid line to the broken line nearest to it it would also be conceivable not to apply the polymer coating in form of an uninterrupted helix type path of viscous polymer material onto the textile fabric but instead apply several self contained polymer paths which are located adjacent to each other in cross machine direction fig5 shows a side view of the machine for the production of inventive belt 1 coating apparatus 18 is shown coating apparatus 18 comprises a forming channel 20 through which textile fabric 5 which at this stage is uncoated at least across a partial width is fed from above and which leaves forming channel 20 in a downward direction and coated across a partial width coating apparatus 18 further comprises means 21 to feed viscous polymer material 21 into forming channel 20 as already explained the permeable textile fabric has a first side 6 facing the provided.
