Abstract
The invention concerns a device comprising rigid or semirigid shafts (120) and at least a member (200) provided with orifices (203) for the passage and direct guiding in translation and angular positioning of a shaft in its controlled rocking movements (F1). Said member (200) is mobile, with two degrees of freedom relative to the loom frame, in translation (F4), along a direction globally parallel to the direction (A–A′) of the weft yarns, and in rotation (P4), about an axis (Z1Z′1) globally parallel to the translational direction (A–A′) of the shafts. Said member (200) can be positioned (F4, P4) by the warp yarns (103) which pass through the eyelets (127) of the shafts (120) which it guides.
Claims10
Shed forming device for a weaving loom of Jacquard type, the device comprising rigid or semi-rigid shafts, characterized in that the device further includes at least one member (200;
- 700) provided with orifices (203;
- 703) for the passage and direct guiding in translation of a shaft, or heddle, (120;
- 620) in its controlled rocking movements (F1), in that said member (200;
- 700) is mobile, with two degrees of freedom relative to the loom frame, in translation (F4), in a direction (A–A′) substantially parallel to the direction of the weft yarns, and in rotation (P4), about an axis (Z1–Z′1) substantially parallel to the translational direction (F1) of said shafts (120;
- 620), and in that said member (200;
- 700) can be positioned in translation (F4) and in rotation (P4) in the afore-mentioned movements by the warp yarns (103;
- T) which pass through the eyelets (127) of the shafts (120;
- 620) guided by said member.
