In the process of hand-weaving floor coverings, various thicker materials can be used for the weft. In order to be able to use sheep wool from our region and threads made from recycled materials, a machine was designed that produces complex coarser threads suitable for hand weaving in a discontinuous process.

At least two previously prepared threads (or narrow ribbons of recycled material) are laid out in parallel on a 2-meter-long table, and wool fibers or a skein obtained by a carding machine are placed next to them. All threads are fixed to the spindle at one end. After the spindle has been rotated a certain number of revolutions, the desired twists are created on the new thread. The spindle axis is then placed perpendicular to the axis of the created thread, which is wound onto the spindle, and a new amount of material is pulled onto the table to continue the process, which is repeated as desired (or needed). The spindle has an electric motor drive controlled by a counter and a speed regulator.
