pyörökehräys
Pyörökehräys, also known as ring spinning, is a widely used method for producing spun yarn from staple fibers. It is a continuous process that involves several key stages. First, the fibers are opened and carded to align them into a sliver. This sliver is then drawn and twisted to form a roving, which is a thicker, weaker strand of fibers.
In the pyörökehräys machine, the roving is passed through a series of rollers that attenuate it to
The primary advantage of pyörökehräys is its versatility, allowing for the production of a wide range of
