A B S T R A C T Drying felts have since many years been provided with a seam in order to facilitate the mounting in the paper machine and during the last three years also the press felts have been provided with such a seam. In order to prevent that the paper web is marked by the seam, the seam is covered by a wadding flap, which is a continuation of the wadding layer which is fastened to the felt. The wadding flap is worn in different ways when the felt is used in the paper machine and its firm- ness will therefore decide the limit for the effective life- time of the felt and marking in the web will occur due to the wearing of the wadding flap. In order to decrease the wear on it, so that a better felt is obtained and also a safer production of paper, the protective flap includes at least one layer , the fibers, the yarns or filaments of which are mainly placed in the moving direction of the felt in the machine.
