  • Publication number: 20100196620
    Abstract: The present invention relates to a method of coating a technical textile belt or fabric for a machine to produce a fibrous web of material, for example paper, cardboard, or tissue, which includes the step of i) providing a belt, whereby a coating is applied onto one side of belt; ii) providing of an applicator device, with which a liquid medium can be applied onto one side of belt without actually coming in contact with the belt; iii) applying the liquid medium onto one side of the belt; and iv) causing the liquid medium to bond and develop in order to allow the formation of a solid coating covering on the side of the belt and/or the inner structure covering at least a portion of the side of the belt. The method according to the present further provides that in invention step iii), the applicator device, follows a previously established raster in applying pre-determined quantities of the coating medium onto a plurality of locations, located within at least one region on the side of the belt.
