Engineered to eliminate manual handle gluing labor, cord unraveling, and handle positioning skew in paper bag conversion, OYANG's industrial paper bag auxiliary equipment portfolio automates kraft roll preparation and handle bonding into a continuous workflow. Operating as a versatile paper bag auxiliary machine suite, our 5 dedicated models encompass high-speed paper handle pasting machine lines (ONL-HFA for flat handles and ONL-HRA for twisted round rope at up to 43 pcs/min), dual-station paper rope twisters (ONL-TW2 at 25 m/min), and 150 m/min jumbo reel rewinders. Built with KCON optical edge centering to hold placement tolerances within ±0.5 mm, this line eliminates manual gluing bottlenecks across luxury retail, food takeaway, and shopping bag production lines.
From raw kraft reels to finished retail shopping bags—each OYANG auxiliary unit synchronizes to deliver non-stop converting throughput.
Five precision machines engineered to eliminate bottlenecks across handle fabrication, slitting, and automated pasting.
Two-in-one automated unit that manufactures flat folded paper handles from reel stock and pastes them directly onto finished bags. Ideal for bakery, grocery, and apparel packaging.
Synchronously twists paper rope cords (Φ2.5–5mm), bonds them into reinforced patch plates, and adheres them onto bag mouths for luxury boutique retail packaging.
High-tensile cord twister offered in single-station (TW1) and double-station (TW2) configurations. TW2 delivers up to 25 m/min with uninterrupted dual bobbin output.
Consolidates small twisted rope bobbins (Ø76mm core) into large jumbo supply reels (Ø400–600mm) at 150 m/min, slashing downtime on downstream handle pasting machines.
Heavy-duty rotary slitter dividing wide kraft reels into exact web widths required for tube forming and handle patch rolls. Available in SL1300, SL1600, and SL1800 formats.
In an automated paper handle pasting machine running at 43 bags/min, loose paper cord twist causes cord snapping, while glue tank temperature drops lead to handle detachment during retail loading. OYANG ensures structural handle integrity and precise patch positioning through verified mechanical tolerances machined across Japanese MAZAK and OKUMA five-axis machining centers:
| Auxiliary Subsystem | Engineering Tolerance / Control Spec | Shop-Floor Production Guarantee |
|---|---|---|
| KCON Dynamic Edge Centering | ±0.5 mm lateral shift compensation | Eliminates visual handle skew across 43 bags/min continuous runs, meeting luxury boutique carton standards. |
| XBS Thermostatic Hot-Melt Tank | PID temperature regulation (±1°C stability) | Maintains hot-melt open time and penetration depth on kraft patches, ensuring handle shear pull strength > 150 N. |
| ONL-TW2 Dual Twisting Spindles | Constant pitch helical tensioning (20–25 m/min) | Prevents cord loose flaring and unraveling, delivering high-density uniform paper ropes (Φ2.5–5.0 mm). |
| MAZAK Machined Cam Linkages | ≤ 0.015 mm guideway parallelism tolerance | Suppresses reciprocating vibration on DELTA robotic transfer arms, eliminating glue overspray and patch jamming. |
By synchronizing INOVANCE servo positioning with heavy-duty stress-relieved steel housings processed inside our 130,000 m² manufacturing park, OYANG paper bag auxiliary machinery completely replaces manual handle pasting while ensuring zero downtime across high-volume paper bag converting shifts.
