Anotations

Scope note:

Perforated cylinders that utilize a pneumatic conveying process to extract airborne fibers, such as dust and dirt, from cotton lint and other non-woven fabrics. Also used to compress a web of fibers into long strips of parallel fibers, thus converting the web to a sliver or roving. These devices generally contain two chambers in between which is a spinning barrel. The flow of material and air enters the vacuum chamber, which is then pushed to the next chamber by the barrel at atmospheric pressure.
