Method for manufacturing a machine felt and machine felt

摘要

The method involves manufacturing an auxiliary substrate web with width that is less than width of a machine felt. Longitudinal yarns (13, 14) are fixed with the auxiliary substrate web, and are connected to each other by an action of a laser beam. The auxiliary substrate web is helically wound until a flattened tube with a longitudinal yarn layer is formed. A portion of the auxiliary substrate web on longitudinal yarn loops is removed. Transverse yarn layers are formed in inner and outer sides of the tube. An independent claim is also included for a machine felt comprising a substrate.
