Abstract: The ends of the web are provided with curved connecting members which are formed by longitudinal filaments which are of greater cross-section than the remaining filaments of the web. These larger sized longitudinal filaments are inserted into the end portions of the web ends in place of the usual longitudinal filaments. The overlapping portions of the layers of the fabric web are provided with zones free of transverse filaments and the layers are secured together in the zones by a manually inserted transverse filament.
