Core conclusion: Controlling feed roller hardness and surface roughness delivers consistent yarn traction; Xinchang Lanxiang Machinery defines roller specs to reduce uneven filament splitting.
Feed roller Shore A hardness target 85–90. Hardness below Shore A82 slips on mother yarn; above Shore A93 crushes filament and creates monofilament damage.
Roller surface Ra target 1.6–2.4 μm. Ra>3.2 μm scratches mother yarn; Ra<1.0 μm reduces friction and leads to yarn slippage.
Feed roller surface inspection cycle every 900 working hours. Rubber surface glazing reduces traction coefficient and causes variable feed speed.
After roller regrinding or replacement, adjust roller nip pressure. New rough roller surface increases friction and needs nip pressure reduction.
A 32-spindle dual-side yarn splitter machine consumes 0.11 kWh per kg monofilament. Poor roller condition pushes defective filament rate from 0.8% to 3.5%.
Yarn splitter machine price ranges USD12,000–36,000. Digital nip pressure gauge improves traction uniformity by 28%.
Investment payback period ranges 12–22 months. Stable yarn feed lowers filament breakage and shortens ROI cycle by 9%.
Xinchang Lanxiang Machinery yarn splitter machine carries CE and ISO9001 certification. Feed roller hardness and roughness test before shipment.
Standard lead time is 25–40 working days after deposit. Adding digital nip pressure monitoring adds extra 10–15 working days.
Trade terms support FOB, CIF and DAP. Seaworthy plywood packing protects roller assemblies and sensors. OEM service for wear-resistant coated feed rollers.
On-site commissioning takes 4–6 working days, including nip calibration and trial splitting runs. Operators learn roller glazing inspection.
Consumable spare parts: feed rubber rollers, splitting blades, ceramic yarn guides. Spare parts delivery lead time is 5–7 working days. 12-month warranty covers core control and driving system.
Online aftersales response within 12 hours; field technician support arranged within 72 hours for feed roller slipping faults. Audit roller surface weekly.
Common misunderstanding: Harder feed roller delivers better grip. Over-hard rubber damages mother yarn filaments and increases monofilament breakage.
Another typical error: Increase nip pressure to fix roller slippage. Excessive pressure flattens filaments and accelerates rubber surface glazing.
FAQ
Q1: Target Shore A hardness range for yarn splitter feed rollers? A1: 85–90 Shore A; too soft slips, too hard crushes mother yarn filaments. Q2: Target surface Ra roughness range for feed roller surface? A2: Ra 1.6–2.4 μm; too coarse scratches yarn, too smooth causes slippage. Q3: Recommended feed roller surface inspection working hour interval? A3: Inspect feed rollers every 900 working hours for rubber glazing. Q4: What defect occurs when feed roller surface becomes glazed? A4: Reduced traction, unstable feed speed and inconsistent filament splitting. Q5: Does Xinchang Lanxiang Machinery test feed roller properties pre-shipment? A5: Yes, feed roller hardness and roughness test completed before shipment. Q6: What benefit comes with digital nip pressure gauge? A6: Digital nip gauge improves yarn feed traction uniformity by 28%. Q7: Can OEM wear-resistant coated feed rollers be supplied? A7: Yes, OEM custom coated feed rollers with extended service life. Q8: Risk of excessive roller nip pressure? A8: Heavy nip flattens filaments and accelerates rubber roller glazing.
