Study Notes
Vertical Feeding Systems
- Utilized in DREF-II, DREF-III, and DREF-2000 friction spinning machines.
- Allows for vertical feeding of multiple slivers.
Inclined Feeding Systems
- Employed by PSL Masterspinner and DREF-5 spinning machines.
- Best suited for coarser yarn production.
Yarn Production
- Feeding fiber streams at an oblique angle is optimal for producing finer yarns.
- Inclined fiber feed enhances fiber length utilization, especially in spinning finer yarns.
Fiber Individualization and Drafting
- Fiber feeding devices enact individualization of fibers.
- Opening roller, pinned beater, or carding drum used for this process.
- Fiber drafting is also a critical function performed by the fiber feeding device.
Carding Equipment
- Carding drum or opening rollers are lined with saw tooth wire clothing.
- Essential for effective fiber processing prior to spinning, ensuring a consistent fiber strand.
