Abstract

A weaving method makes use of a set of weaving frames arranged such that, in each weaving cycle, some of the weaving frames are held in an identical extreme position, while all remaining weaving frames are moved in order to provide different tensions for the top and bottom warp threads at the moment of beating up. The shed is formed so that at the moment of crossing, as the weaving frames change position, the length of the course followed by the crossing warp threads is equal or almost equal to the length of the course followed by the warp threads held in the extreme position.
