What it is
A spinning system in which fibres are dispersed in air and deposited in a high-speed rotor that twists them into yarn. It eliminated the roving and several steps of spinning, and multiplied speed several times over.
The first commercial machine (BD 200) was shown at the 1967 ITMA fair; attribution to Czechoslovakia is the most common, but there were earlier patents (Berthelsen, Denmark, 1937) and Soviet work. Authorship detail is disputed.
What it led to
- cheaper cotton yarns for denim and heavy fabrics
- mass-production spinning with fewer steps
- later air-jet and friction spinning machines
