プラスチックまたは金属プラスチック製軟質チューブの製造方法
Document Type and Number:
Japanese Patent JP2006503737
Kind Code:
A
Abstract:
The invention concerns a method for making flexible tube skirts comprising a step of making a cylindrical sleeve from a planar web including several plastic or metal layers followed by a step whereby said cylindrical sleeve is cut out to the desired length to obtain said skirts. It comprises a step prior to the step of making the cylindrical sleeve, wherein the web is subjected to a plastic deformation resulting in its being thinned by at least 0.5% or in producing a raised surface whereof the amplitude ranges at least between 1/30 and 5 times the thickness. The web is for instance passed through the air-gap between two substantially parallel rolls. Typically, the rolls exert on the web a force ranging between 2.5 and 500 newtons per millimetre of web width.
