Abstract
An industrial fabric, belt or sleeve and a method of making the fabric, belt or sleeve are disclosed. The industrial fabric, belt or sleeve is produced by spirally winding strips of polymeric material, such as an industrial strapping or ribbon material, around two rolls in a side-to-side manner in which a gap between adjacent edges is formed. A second material, for example a gap filler material, is placed between the adjacent edges, and the adjoining edges are joined by melting the filler material, strips of polymeric material, or both. The gap filler material can have a specific cross-sectional shape corresponding to the gap.
