New yarn storage feeding technology by BTSR

BTSR will be heavily promoting innovative and potentially game changing yarn storage and feeding solution at leading trade fairs this year. The Italian company’s recently introduced disruptive Unifeeder technology aims to displace current state-of-art of yarn storage feeding technology and is said to be destined to dramatically impact on the socks, hosiery and knitted textiles manufacturing sectors.

Unifeeder is a new multi-patented concept featuring a brand new Yarn Antitwist System which is said to guarantee total combined yarn feeding and storage control. BTSR says this represents the first ‘positive storage’ feeder concept which has been introduced to the market.

Top Features and Benefits:

• 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)

Cost-Saving, Universally Retrofit-table

• 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)

Specifications:

• 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
