Method for manufacturing a machine felt, and machine felt |
摘要 |
A method for manufacturing a machine felt. Firstly a tube having a longitudinal yarn layer is manufactured with a peripheral length double the length of the machine felt, and a width that corresponds to the width of the machine felt. The tube is compressed into a flattened tube with the formation of longitudinal yarn loops which are exposed by the removal of fibers of a fiber batt layer. An auxiliary substrate web is manufactured with a width that is less than that of the machine felt; for the longitudinal yarns and/or for the auxiliary substrate web, a material is used that absorbs laser energy; the longitudinal yarns are brought together with the auxiliary substrate web and connected by a laser beam; the auxiliary substrate web is helically wound until the tube is formed; and upon exposure of the longitudinal yarn loops, the auxiliary substrate web(s) are also removed.
