FAQ
Q1: What raw materials and fibre lengths can the FA318A draw frame process?
A1: The FA318A is suitable for the drawing and blending of cotton, synthetic fibres and blended slivers within a validated fibre-length range of 15–76 mm. The final drafting settings should be selected according to the raw-material composition, fibre length, feed-sliver weight and required output-sliver quality.
Q2: What production speed and drafting range can the FA318A achieve?
A2: The machine has two delivery heads, a maximum delivery speed of up to 800 m/min and a total drafting range of 4–14. It can normally process 6–8 feed slivers. Actual operating speed depends on the raw material, sliver weight, can size, quality requirements and mill conditions.
Q3: Can the FA318A be connected to an existing cotton spinning line?
A3: Yes. The FA318A can be evaluated for installation between the carding or combing section and the subsequent roving or spinning process. Please provide the models of your existing machines, feed and delivery can sizes, sliver specifications, target output, factory voltage and installation layout. TONGDA will confirm the interface and final configuration before quotation.
Product Advantages
Key Advantages of the FA318A Autoleveller Draw Frame
The FA318A is a high-speed, dual-delivery draw frame developed for efficient sliver preparation in modern cotton spinning mills. It combines automatic levelling, independent delivery control and precision drafting to improve sliver consistency and production efficiency.
1.High-Speed Dual-Delivery Production
The FA318A is equipped with two delivery heads and reaches a maximum delivery speed of up to 800 m/min. Its dual-delivery design enables the machine to process more sliver within a compact production area, making it suitable for spinning mills that need higher output and better equipment utilisation.
2.Precise Autolevelling for Consistent Sliver Quality
The Uster UQA autolevelling system monitors sliver variations and adjusts the drafting process to improve output consistency. Combined with eddy-current detection technology, the system helps reduce unevenness before the sliver enters subsequent spinning processes.
3.Independent Drive and Operation
Each delivery section features independent drive and control. One delivery head can be adjusted or operated without unnecessarily affecting the other, providing greater production flexibility and reducing the impact of localised interruptions on the complete machine.
4.Stable Drafting with Lower Operating Noise
The five-over-four pressure-bar, two-zone curved drafting system provides a total draft range of 4–14. Timing belts and Poly-V belts deliver accurate power transmission with reduced vibration and noise, supporting stable operation at higher delivery speeds.
5.Intelligent Control and Easier Maintenance
PLC control, digital machine monitoring and overhead photoelectric detection improve operational reliability. An automatic clearer supports regular cleaning, while optional forced lubrication and automatic doffing can reduce manual work, gear wear and routine maintenance requirements.
