Abstract
Drying felts provided with a seam in order to facilitate mounting in a paper machine and press felts with such a seam in order to prevent the paper web from being marked by the seam have a wadding flap covering the seam as 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 a paper machine and its firmness limits the effective lifetime of the felt and marking in the web occurs due to the wearing of the wadding flap and in order to decrease this wear and to obtain a better felt and a safer production of paper, the protective flap includes at least one layer (6) of wadding having the fibers, yarns or filaments thereof mainly oriented longitudinally in the moving direction of the felt in the machine.
