Motor-stator roller-feeder material-deviation diagnostic
Misalignment should be isolated in a measured order: incoming camber, guide symmetry, passline, roll traction, release/pilot action and die drag—not corrected by random guide pressure.
Application-Specific Process Route
The route below isolates strip misalignment one cause at a time, from the symptom to a controlled correction.
Inputs to Freeze Before Selection
- Strip edge/camber measurements and coil orientation
- Guide positions, passline height and roll parallelism reference
- Roll pressure, surface condition and slip evidence
- Release timing, pilot entry and die drag indicators
- Drift rate, cycle phase and left/right feature measurement
- Containment range and approved restart sample plan

Engineering Decision and Verification Table
| Decision gate | How to verify | Required record |
|---|---|---|
| Incoming material | Reverse/replace coil or measure camber before adjustment | Material observation record |
| Guide/roll geometry | Measure symmetry and contact marks | Setup dimensions and photographs |
| Pilot/release | Single-cycle with visible strip freedom | Timing observation and witness marks |
| Correction result | Compare edge track and stamped features before/after | Sample table linked to change |
Step-by-Step Diagnosis
Failure Modes and Stop Conditions
- Guide-force masking: Stop tightening guides when strip bows or edges mark
- Multiple simultaneous changes: Return to baseline and change one variable
- Uncontained suspect parts: Hold output since the last verified tracking check
Acceptance Record
Freeze the released drawing and material revision, machine configuration, interface list, recipe, sample plan and measuring method. Record exceptions and the safe restart route, and identify the tested configuration in every reported result.
Equipment Reference
Published model ranges for each RFS mechanical feeder for power presses are listed on the product page; for a supplied machine, the approved quotation and the manual revision define the exact configuration.
