The document discusses doubling machinery used at a textile company. It describes two types of doubling machines, including their manufacturers, models, years, and number of machines and cones. It provides the production capacity of 161.20 kg/shift and technical specifications like spindle RPM and traverse length. It also lists the thread per inch counts for different yarn counts. Finally, it gives a brief description of ring doubling where only twist is provided before winding onto cones to clear any doubling defects.

5. Ring Doubling
Here only twist is provided to the parallel wound yarns.
These yarns are the wound in cones at cone winding. At
cone winding the yarn is cleared of doubling defects.
