Abstract
A strip of material, especially for papermaking machine cloth covers for the pressing zone, as a filter or as pressing pad for the particle-board presses, comprises individual, longitudinal threads and orthogonally thereto individual transverse threads. In order to endow the strip with a structure such that on one hand it can be manufactured rapidly and economically, and on the other hand to allow wide latitude in shaping its properties, the threads (1) extending in one direction always consist each of a core filament (2) and of at least one loop thread (3) enclosing this filament.
