Abstract

PURPOSE:To coat a flexible metal tube tightly and to eliminate the relief phenomenon of the plastic coating on the tube, by wrapping a heat-shrinkable plastic, which shrinks longitudinally and expands at a specific ratio or higher laterally in heat fusing, around a flexible metal tube, and by heat fusing the plastic. CONSTITUTION:A heat-shrinkable plastic, which shrinks longitudinally and expands at 15% or higher laterally is wrapped around a flexible metal tube, e.g. a corrugated tube, heated and fused to give the desined coated metal tube.
