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.

The invention is a method for manufacturing a felt belt having a support which is embedded in a fiber matrix and is made up of at least two yarn layers arranged one above another, at least one is a longitudinal yarn layer made up of longitudinal yarns extending in parallel fashion, and at least one is a transverse yarn layer made up of transverse yarns extending in parallel fashion, transverse yarns being present that are continuous over the width of the felt belt. For each longitudinal yarn layer, a first support module is manufactured, by means of a first auxiliary support web, at a width that is less than the width of the completed felt belt, the first auxiliary support web being wound in helical fashion, before, during, or after the application of yarns, to a width that corresponds to the width necessary for manufacture of the completed felt belt.

A liquid-permeable support for a paper machine clothing that is usable in the press section of a paper machine includes a support having at least two plies that brace against one another via discrete bracing elements. At the points where the plies brace against one another, there is applied on one or both sides an elastic coating which is embodied elastically in such a way that the spacing of the plies under pressure loading is decreased by elastic compression of the coating. Upon pressure relief the spacing is increased again by elastic recovery of the coating.
