FAQ
Q1: What is the FA471 roving frame used for?
A1: The FA471 drafts, twists and winds prepared sliver into roving before ring spinning. Its 24-spindle layout can support laboratory testing, textile training and pilot production.
Q2: What materials and package sizes can the FA471 handle?
A2: The page states a cotton staple length of 22 to 38 mm and also lists operating data for polyester. The bobbin measures 45 mm in diameter and 445 mm in length, while the full package measures 152 mm in diameter and 406 mm in length.
Q3: What information is needed for a machine proposal?
A3: Please provide the fiber type, staple length, feed sliver data, target roving count, required twist, bobbin dimensions, planned batch size, local voltage, frequency and available room dimensions.
Product Advantages
1.Compact 24-Spindle Layout
The FA471 uses 24 spindles with a 220 mm spindle gauge. Its compact configuration fits laboratory trials, textile training and pilot spinning work where a full production frame is not required.
2.Four-Roller Double-Apron Drafting
The short double-apron drafting arrangement manages fiber movement through four roller lines. The stated total draft range of 4.13 to 13.28 supports different roving preparation needs.
3.Two-Inverter Drive Arrangement
One inverter manages the flyer and drafting rollers, while the second manages lifting and winding. This arrangement coordinates drafting, twist and package formation during operation.
4.Cotton and Polyester Processing
The stated cotton staple length is 22 to 38 mm. Published practical spindle speeds reach 1,200 rpm for cotton and 1,400 rpm for polyester, subject to material and process settings.
5.Roving Length and Process Monitoring
The control panel displays spindle speed, preset length, accumulated length and current length. Photocells and signal lamps help operators identify breaks or other operating interruptions.
