Abstract
A weaving loom including a mechanism drawing-in threads, for insertion of picks, and for formation of a weaving shed, so as to render possible formation of a continuous angle or corner by a thread during weaving. The loom preferably also includes a vertical offset system, so that it is possible to weave a three-dimensional surfacic structure, the threads of which are continuous between the faces and at the level of the edges. The loom can be configured particularly for manufacture of continuous tridedral corners that are used as reinforcements for composite structures.
Claims15
A weaving loom used for weaving a fabric in weft of which at least one thread forms a angle, with the loom structure forming a frame with four sides that comprises:
- first means for drawing-in threads on a first side to form a first strip between the first side and a third side;
- second means for drawing-in threads on a second side to form a second strip between the second side and a fourth side, including open hooks around which the threads can form a loop;
- a first weaving-shed formation system on the first strip at a level of the first side;
- a second weaving-shed formation system on the second strip at a level of the second side, including open elements for manipulating the threads;
- a spool configured to contain a winding of weft thread intended to weave the strips;
- a receptacle located between the first and second sides, and the first and second strips, used to hold the spool;
- and
- a first and a second pick-tamping comb traversing the first and second strips.
