US 2014/0174689 A1 · INDUSTRIAL FABRIC COMPRISING SPIRALLY WOUND MATERIAL STRIPS AND METHOD OF MAKING THEREOF

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.

Dependent claims

An endless industrial belt or sleeve comprising:

a polymeric material in the form of a ribbon comprising
a first longitudinal edge surface having a first edge profile, and
a second longitudinal edge surface having a second edge profile,
said polymeric material being spirally wound in a plurality of turns such that the first longitudinal edge surface of said polymeric material abuts said second longitudinal edge surface of an adjacent spiral turn of said polymeric material, thereby forming a gap therebetween;
and
a filler material inserted in said gap, wherein a cross-sectional shape and dimension of said filler material corresponds to the cross-sectional shape and dimension of said gap.
