Abstract
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.
