Improved yarn quality is a substantial competitive advantage for today’s spinning mills. Accotex cots are standard front cots accepted by the machine manufacturers, on both the regular and the compact spinning frames. Improving yarn values (evenness, thin places, and thick places) require a high-quality soft cot; the performance of this cot however depends largely on the proper preparation of the cot surface.
The stone should be dressed with a diamond aft er every 1500 top rollers
The stone must be cleaned every 15 minutes, using either compressed air or a soft metal brush
After mounting the new cots have to be buffed all to the same outer diameter.
The cot surface after grinding is clean and free of grinding dust and grinder cuts.
The cot has the correct surface roughness (Ra-value) after grinding
Grind as fast as possible and as long as necessary.
The freshly buffed cots should relax for approx. 24h before they will be used.
