Grassroot Innovations

For weaving a saree, a process of winding, where labourers and two tree trunks are required for the operation. To mechanise this process, Prafulla has developed a self-propelled machine that facilitates winding of cotton thread for weaving of sarees. The drum receives power directly from a 0.25hp electric motor and this can be operated manually as well. Weft winding work is carried out over the entire length of the drum. Prafulla has developed Purra bed (uniform thread distribution system), which automatically changes its direction of movement. This Purra bed has two cycle hubs for easy movement over the frame track. There is a small vertically placed thin rod attached with the chain loop and Purra bed is placed over this rod. So when it makes a U-turn after completing half cycle, the Purra bed automatically changes its direction of motion. The second Purra bed travels on other end of this drum as both Purra beds are connected by means of a square pipe. In this way, both the thread distribution systems work automatically and help in improving productivity. The machine has the capacity of winding 10 bundles of yarn over the drum within an hour.

The Automatic Weft Winding Machine speeds up saree-weaving prep by reducing manual labor and automatically distributing thread evenly. This efficient machine winds 10x faster and offers both electric and manual operation.
