Loom multi - node crank opening device advantage

The multi-node crank opening device is an important part of the loom. Compared with the common simple crank opening device, the multi-node crank opening device has the following advantages:

Can obviously improve the fabric surface texture, make the fabric full. Due to the slow opening, sufficient weft insertion time can be achieved at high speed weaving. The special opening curve makes the tension of upper and lower warp yarns change more evenly at the opening. Even at high speed running, obvious breakage can be improved, while ordinary crank opening can only be woven at low speed due to the lack of the above characteristics. Because of the matching of the motion law of heald frame and the breaking curve of weft, it is easy to weave heavy fabric, while ordinary crank opening can only weave light fabric. Because the complicated CAM opening device of the rotating device is eliminated, the equipment investment can be greatly reduced. The optimized crank shank makes the device more adaptable and reliable than the ordinary crank device, and the machine material consumption in the weaving process is also significantly reduced, which is very suitable for the weaving of all kinds of plain weave and light-edge fabric with large orders for a long time.
