Title
(EN) METHOD AND APPARATUS FOR MANUFACTURING DRY LINERS FOR PIPE REPAIR
(ZH) 制造用于管道修复的干燥衬里的方法和设备
Abstract
(EN) A method of manufacturing a liner for reinforcing a pipe includes providing a continuous first reinforcing fibers extending in a first direction, moving the first reinforcing fibers in a machine direction such that the first direction is parallel to the machine direction, providing sheets of a material having second reinforcing fibers extending in a second direction, placing the sheets onto the moving first reinforcing fibers such that the second direction is substantially perpendicular to the first direction, and folding the sheets into a closed shape.
(ZH) 一种制造用于增强管的衬里的方法,该方法包括:提供沿第一方向延伸的连续的第一增强纤维;将第一增强纤维沿机器方向移动,使得第一方向平行于机器方向;提供具有沿第二方向延伸的第二增强纤维的材料的片材;将片材放置在移动的第一增强材料上,使得第二方向基本上垂直于第一方向;并且将片材折叠成闭合形状。
