Abstract

In a sheet, longitudinal slots of limited length and staggered relative to each other are formed, so obtaining a solid fibre or fibril assembly. The sheet is drawn to reduce its extension before or after forming the slots, and may be split into bands which are twisted together. After slotting and after drawing, some of the fibres are made to leave the assembly.
