Unifeeder 2

UNIFEEDER 2  represents a breakthrough solution drastically overcoming the state-of-art of storage feeding technology, destined to supply an epochal change in textile market technological offer.

A new concept multi-patented system  able to guarantee a total combined yarn feeding and storage control, thus representing the first 'positive storage' feeder Concept introduced on the market.


  • Real-time Total Yarn Control - from input yarns (knots, breaks, tears), through yarn storage (constant storage), to output yarns (LFA and yarn constant tension feeding)
  • High Precision Real-time Yarn Consumption Measurement (LFA) - granted by BTSR proprietary optical ring
  • Prevent Yarn Twisting - thanks to new-concept revolving drum and optical ring technology closed-loop integrated system (yarn storage feed equal to yarn feeding speed)
  • Real-time Constant Tension Self-adaptive Technology -bringing TOP Production Repeatability, based on the high-frequency magnetically controlled floating ring and output tension sensor closed-loop control system
  • Yarns knots, breaks, tears detection - granting real-time machine stop signaling, thanks to input knot catcher and additional built-in sensors
  • Yarn Graduation Compression Capability (0,1 gr. resolution) - for technical textile applications (i.e. sock leg, seamless..)
  • Yarn and Needles Breakage Prevention - avoiding second-rate products and useless machine stops
  • AUTO-LFA Function - Auto-compensate Yarn LFA variation (i.e. due to fluff accumulation in the yarn finger,..), granting constant quality and preventing yarn misplating & breakage, (optional, with MATRIX FEEDER terminal)


  • Minimized size and weight - incredibly minimized size and weight, thus allowing the simplest and cost-saving installation configurations (i.e. single ring, ..).
  • No additional input yarn motion sensor required
  • Reduced electrical consumption
  • Plug & play - for easy and quick installation
  • User-friendly - easy yarn thread-up and easy yarn tension set-up
  • Universal Retrofitting - on all machine typologies available on the market
  • Styles Programming & Unlimited Graduation Compression for standardized production - coming with PC-LINK NEMO PROFILER software (optional)


  • Programmable tension: 0,2 gr. ÷ 50 gr.
  • Yarn Feeding speed: up to 1000 mt/min. (@ 24 V /36 V)
  • Yarn Storage Coils programming: up to n. 30
  • Weight: 780 gr.
  • Size: Height 210 mm (265 mm), Width 77 mm, Depth 125 mm
