Wikipedia ascribes this invention as “cotton carding” If you know carding (aligning the fibers) This is not carding.

Science historian Joseph Needham ascribes the invention of bow-instruments used in textile technology to India.The earliest evidence for using bow-instruments for carding comes from India (2nd century CE). These carding devices, called kaman (bow) and dhunaki, would loosen the texture of the fibre by the means of a vibrating string.

This is not a carding machine. The title of the video translates to wool and cotton throwing beam. Its interesting to see this in action and how its built. But I am unsure of its purpose. Perhaps Loosening the material for stuffing pillows? Working organic matter and loosening prior to drum carding? I thought I would document this, as the language barrier does not allow for this to be catalogued and fully understood and I have been interested in this machine and its purpose since I initially saw the illustration, while I researched carding machines.
