A seaming element for an industrial textile, and methods of manufacture. The seaming element body is constructed from a single layer of polymeric film that is folded to provide a fold region and arms that comprise a first region, and a further second region. The first region is bonded to surfaces of an edge region of the textile, while the second region comprises a plurality of spaced-apart aligned protrusions extending from the first region, each protrusion comprising an interior space defined by an upper layer; a lower layer; and a loop at the fold region that connects the upper and lower layers. The interior space is divided into an outer securing region and an inner securing region by either a rib member placed between and bonded to an inner surface of at least one of the upper and lower layer, or by bonding a portion of the upper layer with a portion of the lower layer at a constriction zone. The outer securing region is interdigitatable and alignable with the inner securing region of a corresponding second seaming element bonded to another region of the textile, to define a first channel; and the inner securing region is interdigitatable and alignable with the outer securing region of the corresponding second seaming element, to define a second channel. A securing element is placed in the two channels. |
