Q1: What is AM‑170BD Automatic Edge‑alignment Straight & Bias‑grain Rewinding Machine?

A1: AM‑170BD Automatic Edge‑alignment Straight & Bias‑grain Rewinding Machine is flexible‑material rewinding equipment, specially designed as pre‑process matching machine for AM‑170ZMB strip‑cutting machine. It performs straight‑grain and 20‑70° bias‑grain rewinding. It is equipped with infrared electronic edge‑alignment, meter/yard preset‑length auto‑stop and adjustable winding‑tension mechanism. It supports forward/reverse rotation, inching‑auto mode switch. It is used for round‑roll packaging or pre‑rewinding before strip‑cutting, to guarantee uniform strip width in downstream process.
Extension: Compare with AM‑635 fabric‑inspection rewinder: AM‑635 focuses on fabric defect‑inspection & slitting without bias‑grain winding; AM‑170BD specializes in straight /bias‑grain rewinding, without inspection light‑box, prepared for strip‑cutting process. Typical process chain: laminator → AM‑635 inspection rewinder → AM‑170BD rewinder → AM‑170ZMB strip‑cutting machine.

三. Utility, Installation & Commissioning

Q6: What utility conditions are required for AM‑170BD Automatic Edge‑alignment Straight & Bias‑grain Rewinding Machine?

A6:Power supply: optional 220V single‑phase or 380V three‑phase, reliable protective earthing is mandatory. No compressed‑air source required. Avoid strong direct light hitting infrared sensor. Reserve space for fabric threading, roll handling and maintenance.
Extension: Machine net weight 450KG, load‑bearing floor required. Direct sunlight will interfere infrared edge‑tracking sensor.

Q7: What are requirements for installation & placement of AM‑170BD Automatic Edge‑alignment Straight & Bias‑grain Rewinding Machine?

A7:Place machine on flat hard load‑bearing floor and level whole unit. Reserve surrounding clearance for threading, roll handling and maintenance. Keep away from heavy‑dust environment. Prevent strong direct light onto infrared sensor eyes.
Extension: Check doorway & aisle dimension before machine delivery. Reserve space for roll lifting & handling.

Q8:What is complete test‑running operating procedure for AM‑170BD Automatic Edge‑alignment Straight & Bias‑grain Rewinding Machine?

A8:

1.Confirm reliable power earthing. Clean infrared edge‑tracking sensor lenses, verify smooth rotation of all rollers.
2.Fabric threading: select roller‑passing path according to material property. Skip small double‑thread roller for thin stretch‑prone material. Apply sewing oil on stainless‑steel supporting tube for easily‑deformable thin material to reduce friction.
Extension: Minimize roller‑pass count for thin material to lower stretch risk.
3.Edge‑alignment initialization: Power‑on, move U‑shaped infrared‑edge‑alignment slider & knurled‑roller bearing block to middle collinear position, temporarily disable edge‑alignment. Rewind 1‑2 meters fabric, then align sensor eyes to fabric edge and enable edge‑alignment function.
4.Process setting: Select straight‑grain or bias‑grain mode. Set angle 20‑70° for bias‑grain. Reference check for 45° bias‑grain: A‑B distance 10mm longer than A‑C; E width 0.5‑1cm narrower than D width.
5.Set winding tightness: Keep looser roll for strip width＞20mm; keep tighter roll for strip width＜20mm.
6.Set target length on meter‑yard counter; choose inching mode for commissioning, auto‑mode for mass‑production; adjust speed, reduce speed under bias‑grain condition.
7.Perform trial rewinding, inspect edge neatness and winding tightness. Start formal production after sample acceptance. Machine auto‑stop when preset length is reached.
8.Use forward‑reverse rotation for roll unloading after production. Do not disassemble electric components upon failure, contact manufacturer support.

Q9: What precautions for bias‑grain winding and winding‑tightness adjustment?

A9:Edge‑alignment is harder under bias‑grain winding, lower running‑speed is required. Use dimension reference to verify 45° bias‑grain. Adjust winding tightness corresponding to target strip‑cutting width. Do not over‑tighten thin material to avoid permanent stretch. Over‑loose roll will cause strip‑width fluctuation in downstream cutting.
Extension: Re‑verify angle and tightness after material‑batch change, do not reuse old parameters directly.

Q15: Common faults and troubleshooting guidelines?

A15:

1. Wandering & uneven roll edge: Perform full edge‑alignment initialization again; clean infrared sensor lens; check whether slider bearing is stuck.
2. Fabric width narrows after rewinding: Over‑tension of stainless‑steel supporting tube; reduce roller‑pass quantity; skip double‑thread roller for thin material and apply sewing oil for friction reduction.
3. Machine does not auto‑stop at preset length: Check meter‑yard encoder wiring, confirm counting signal is normal.
4. Incorrect bias‑grain angle: Re‑check angle‑adjustment mechanism; verify dimension A‑B, A‑C, D, E; inspect guide‑roller parallelism.
5. Wrinkled roll: Improper winding‑tightness setting; check whether fabric is twisted in threading path. Extension‑added frequent site faults:
6. Continuous edge‑drift under bias‑grain rewinding: Moderately reduce running‑speed; ensure sensor eyes aim accurately at fabric edge; rule out wavy‑edge defect of raw material itself.
7. Collapsed loose roll: Insufficient overall winding tension, moderately increase tightness setting.
