SPIRAL WOUND TUBES, METHOD AND APPARATUS FOR FORMING THE SAME

摘要

Spiral wound tubes (20) may be formed utilizing the method and apparatuses (100) described herein. The method includes providing a mandrel (110) and a web material (10) having a first overlap region (14) and a second overlap region (18). A binding agent (30) is applied to at least one of the overlap regions. The mandrel (110) is wrapped with the web material (10) such that t he second overlap region (18) covers the first overlap region (14) of the previously wound web and the binding agent (30) is disposed between the previously wound first overlap region and the currently wound second overlap region. The spiral wound tubes (20) of the invention demonstrate improved axial crush resistance.
