Web coating with self-tightening capacity.

摘要

Web coating with self-tightening capacity.; The invention relates to a laminar coating self-tightening capacity element, of the type consisting of multiple bands of substantially rectangular fabric elongated, arranged one beside the other, partially overlapping its edge regions and are secured together by needling , welding and adhesive or other means, and such that the tissue of the individual bands is constituted by yarns having elastic characteristics resilient deformations to which are submitted said bands in the winding and unwinding of the web avoiding the formation of wrinkles after prolonged use.
