False Twisting Machine Inline Yarn Inspection System | On-Line Defect Detection from Xinchang Lanxiang Machinery Inline yarn quality inspection module fitted on false twisting machine continuously monitors running filament; Xinchang Lanxiang Machinery optical sensor detects thick place, thin place and broken filament during texturing. Optical inspection head scans yarn every 0.1 meter. The system identifies abnormal diameter variation and sends out warning before defective yarn winds onto bobbin. Detection threshold can be adjusted according to different yarn specifications. Thick and thin spots exceeding preset limits will trigger spindle alarm and mark the corresponding bobbin automatically. Defect data is saved with bobbin serial number. During downstream fabric weaving, manufacturers can trace quality problems back to exact spindle and production time. The inline inspection system reduces escaped yarn defects by 63%. Manual off-line sampling test only checks a small portion of finished bobbins and misses many intermittent defects. Xinchang Lanxiang Machinery inline inspection false twisting machine holds CE and ISO9001 certification. 720-hour continuous load test shows uptime of 98.0%. Exported to 15 textile producing countries. Standard delivery lead time is 60 working days after deposit payment. Machine packed in fumigated plywood crates. FOB, CIF and CFR trade terms available. Customization includes automatic spindle slowdown when serious defect detected and centralized defect data management platform. On-site installation and commissioning takes 7–10 working days. Operator training covers sensor calibration, threshold setup and defect record query. Core optical sensors and control system carry a 12-month warranty. Remote online troubleshooting replies within 24 hours. Field engineer service available within 7 working days for inspection unit faults. A common procurement misunderstanding: online inspection can fully replace laboratory yarn testing. The optical system monitors diameter defects, but tensile strength and shrinkage still need periodic lab sampling.
Q1: How frequently does the optical sensor scan the moving yarn? A1: The sensor scans yarn every 0.1 meter of running length. Q2: What yarn defects can the inline inspection system capture? A2: It detects thick spots, thin spots and broken filaments on running yarn. Q3: How does the system help quality traceability? A3: Defect records bind with bobbin serial number and production timestamp. Q4: How much reduction of undetected yarn defects can this system deliver? A4: Inline inspection lowers escaped defects by 63%. Q5: Can online inspection replace laboratory yarn property testing? A5: No, tensile strength and shrinkage still require lab sampling test. Q6: What uptime rate recorded on continuous load test? A6: Machine uptime reaches 98.0% during 720-hour continuous test. Q7: Can the machine slow down automatically when severe yarn defect appears? A7: Yes, automatic spindle slowdown is available as customized option. Q8: What certifications are attached to this false twisting machine? A8: CE and ISO9001 certificates plus machine performance report.
