Model : HY383 - Covering Machine

Uses : According to the requirements of product, it can produce single-covered yarn and
double-covered yarn, applicable for choosing many kinds of fibers as outer
covered yarn. The typical core yarn is polyurethane yarn, and the outer covered
yarn may use real silk, artificial silk, medium high-count cotton yarn, hemp
yarn, or plied core-spun yarns such as nylon yarn, artificial silk and
multiple-ply cotton yarn. It produces high-grade and various grades of yarn
materials to follow with modern fashion and help clients to improve their
products competitive power in the market.



Features :

• excellent mechanical shape, convenient to debug and operate;

•Y-Δ start, equipment run smoothly, few broken-end, uniform twist and high
quality;

• twist, drafting and winding respectively be transformed by three groups of
gears, can be randomly adjust to meet the different process requirements;

• multiple wrapping and twisting function, applicable for wrapping and twisting
all kinds of special yarns and threads.
