Visual inspection of yarn cones on the winding line — catching winding faults, contamination, and shape defects in real time.
OCR-based doff card scanning to digitize production records, eliminating manual data entry from the shop floor.
Challenge
Grasim Industries, an Aditya Birla Group flagship, runs large-scale viscose staple fibre and yarn production. Yarn cone quality depends on tight control over winding tension, contamination, and cone geometry — defects caught late mean entire batches rejected by downstream customers. Meanwhile, doff cards — paper records tracking each production run — were being transcribed manually into ERP systems, creating bottlenecks and data entry errors.
Solution
inspection + document digitization
Raru Runtime performs continuous visual inspection on the winding line. Cameras capture every cone as it's produced, and the model flags winding faults (ribboning, stitching, overthrow), surface contamination, and dimensional irregularities — all without stopping the line.
Longlichi scans doff cards at the point of production. Operators place the card under a camera, and the system extracts all fields — batch number, machine ID, operator, weight, grade — and pushes structured data directly into Grasim's ERP. No typing, no transcription errors.
Results
of cones inspected automatically
doff card processing
- Near-zero manual inspection on the winding line
- Doff card data available in ERP within seconds of production, not hours
- Quality traceability from fibre to finished cone
