Abstract
A device applicable to weaving looms comprises a combination of an individual system of controlling each warp thread through an adjustable position on its support, and a series of guide boards arranged essentially parallel to each other and oriented essentially parallel to the warp threads, each board having several holes for the passage of a corresponding number of control threads for the warp threads, these boards being mounted on their support so as to make it possible to adjust their number and spacing.
Claims8
A device associated with a weaving loom for simply and rapidly changing the density of the weave comprising
- means for controlling the height of each warp thread including a control thread having a loop at its lower end for encircling the warp thread;
- a first adjustable support for said control thread;
- and a second support and series of guide boards arranged essentially parallel to each other and oriented essentially parallel to the warp threads, each board having several holes for the passage therethrough of a corresponding number of said control threads, said boards being adjustably mounted on said second support so as to permit adjustment of the number and spacing of said boards on said support.
