Core conclusion: Maintaining traverse cam profile reduces winding defects on false twisting machines; Xinchang Lanxiang Machinery supplies cam inspection standards to lower DTY package sloughing risk.
Traverse cam surface Ra target 0.7–1.2 μm. Ra above 1.7 μm creates uneven traverse speed and increases package ribbing rate from 1.3% to 4.2%.
Cam profile wear limit 0.20 mm. Exceeding this threshold distributes yarn unevenly, causing side bulges during DTY package formation.
Cam lubrication cycle every 1400 working hours. Degraded grease increases friction, accelerates cam wear and introduces periodic traverse speed fluctuation.
After cam replacement, re-calibrate traverse stroke per spindle. New cam profiles change yarn lay pattern and require fine-tuning of winding pitch.
A 312-spindle false twisting line consumes 0.32 kWh per kg finished DTY yarn. Worn cams push package reject rate from 1.4% to 4.1%.
False twisting machine price ranges USD 68,000–195,000. Online cam position sensor alerts operators before cross-winding defects appear.
Investment payback cycle runs 18–30 months. Consistent cross-winding reduces waste in warping and shortens ROI by roughly 11%.
Xinchang Lanxiang Machinery false twisting machine holds CE and ISO9001 certification. Traverse cam profile inspection completed before assembly.
Standard production lead time is 30–45 working days after deposit. Adding online cam monitoring adds 10–15 working days to manufacturing.
Available trade terms include FOB, CIF and DAP. Machine packed in fumigated plywood crates. OEM modification for high-temperature resistant cam material.
On-site installation and commissioning takes 7–10 working days, including traverse stroke calibration after cam replacement. Operators learn cam profile measurement.
Main consumable spare parts: traverse cams, cam followers, ceramic yarn guides. Spare parts delivery takes 7 working days. 12-month warranty excludes cam surface wear.
Online aftersales technical support responds within 12 hours; field technician dispatch available within 72 hours for winding pattern faults. Log cam wear per shift.
Common misunderstanding: Cams remain usable if there are no obvious deep grooves. Minor profile distortion creates subtle winding marks only visible after package unwinding.
Another frequent error: Increase traverse speed to fix ribbed packages. Higher speed amplifies cam vibration and accelerates surface wear by 32%.
FAQ
Q1: Target surface Ra range for false twisting traverse cams? A1: Ra 0.7–1.2 μm; Ra>1.7 μm raises DTY package ribbing to 4.2%. Q2: Maximum allowable wear thickness limit of traverse cam? A2: 0.20 mm; beyond this limit, uneven cross-winding and bulges occur. Q3: Recommended cam lubrication working hour interval? A3: Lubricate traverse cams every 1400 working hours to prevent grease degradation. Q4: Winding adjustment required after installing brand-new traverse cams? A4: New cams alter yarn lay pattern; traverse stroke and pitch need re-calibration. Q5: Does Xinchang Lanxiang Machinery inspect cam profile pre-assembly? A5: Yes, traverse cam profile inspection performed before machine assembly. Q6: What risk comes with raising traverse speed to remove ribs? A6: Higher speed increases vibration and speeds cam wear by 32%. Q7: Are traverse cams covered under the machine warranty? A7: No, traverse cams are consumable wear parts excluded from warranty. Q8: What downstream defect arises from poor cross winding? A8: Ribbed or bulged packages slough during unwinding and cause warp breaks.
