Abstract
A needled press felt for dewatering of cellulose pulp in a paper making machine consists of a multi layer base fabric having longitudinal and transversal threads. In order to improve the dewatering capability of the press felt and making it easy to assemble, the dewatering side of the press felt consists of layer of coarse yarn (3), which has a weight per unit of length, which is at least twice as great as the one of the remaining parallel yarns (1, 2) of the base fabric. Further a seam which can be opened is arranged transversally to the running direction of the felt in the paper making machine.
