摘要
The invention relates to the covering with sheet material of flexible symmetrical angulate tubes, especially components of packages. By utilizing the resilient cross-sectional deformability of the tubes, there is provided a method and apparatus where the tube is mounted onto a cylindrical mandrel having a circumference corresponding essentially to the inner circumference of the tube and thereafter applying the sheet material around essentially the entire circumference of the tube.
