#Knots_from_the_book_on_the_roof. From sketch to implementation

This section presents some of the components described in the literature from the "Double-lock standing seam technology" series and implemented by metal roofers.

   Node name:

Formation of the transverse edge at the outer edge of the gutter using a non-standard solution for forming the sides without making cuts in the folds. The formation of a volumetric texture from a flat sheet is carried out by forming bend lines on its surface and laying deep folds along them - the "folk" name is "origami".

   Detailed description of the node:

     In Book 3 " Double-lock standing seam technology. Above-the-wall and built-in gutters"
