A suit cover bag making machine (also recognized as a garment bag making machine or coat cover converter) automates the continuous roll-fed fabrication of long-format protective apparel covers for tailored suits, bridal wear, and dry-cleaning distribution. Operating at continuous speeds of 30 to 50 finished covers per minute, the flagship OYANG XG1200 bag machine integrates inline center zipper insertion with automated slider attachment, continuous ultrasonic lace hemming, curved hanger port die-cutting, and synchronized cross-cutting. This high-speed inline architecture replaces up to 15 manual sewing stations while maintaining strict ±1.0 mm edge alignment across bag lengths exceeding 1,600 mm.

Protective garment covers for suits, overcoats, and evening gowns represent a high-margin segment in industrial packaging. However, their physical dimensions (typically 600 mm wide × 1,000 to 1,500 mm long) combined with multiple functional components create severe production constraints on traditional shop floors:
The inline sewing non woven machine architecture implemented on the OYANG XG1200 replaces needle stitching entirely with acoustic fusion and servo motion:
A wide non-woven web (typically 60 to 100 GSM spunbond or breathable laminated material) unwinds under closed-loop dancer tension control. Precision ultrasonic rotary knives slit the center channel where the front closure zipper will be situated.
Continuous nylon coil zipper tape is decoiled from a pay-off reel. An automated mechatronic slider inserter loads and locks the zipper puller onto the chain in milliseconds, eliminating manual puller assembly entirely.
Dual high-power 20 kHz ultrasonic sonotrodes fuse the lateral fabric flaps directly to the nylon zipper ribbon. The molecular bond provides peel strength exceeding 120 N without puncturing or weakening the non-woven fibers.
At the top shoulder line, a quick-cycle hydraulic die shears the curved coat hanger opening. Reinforced ultrasonic perimeter welds encircle the port, preventing tear propagation when heavy winter coats are suspended.
Specially patterned rotary ultrasonic lace wheels seal the outer vertical perimeters, embossing decorative and durable bonded edges while trimming excess scrap in a single synchronized pass.
High-speed rotary guillotine shears cut the finished suit cover to the exact programmed length (programmable from 600 mm to 1,600 mm via the HMI terminal) and transfer completed units onto an automatic counter stacking conveyor.
The capital justification for installing a dedicated garment cover machine with zipper becomes evident when evaluating production economics against traditional sewing workshops:
Result: By eliminating manual stitch stations and thread consumables, an apparel converter amortizes the capital investment of an OYANG XG1200 within approximately 5 to 7 high-volume export contracts.
| Manufacturing Metric | Manual Workshop Sewing Method | OYANG XG1200 Automated Platform |
|---|---|---|
| Continuous Conversion Velocity | 0.4 – 0.5 units/min per operator | 30 – 50 units/min (Continuous auto) |
| Zipper & Slider Assembly | Hand-cut zipper, manual puller attachment | Fully automated inline zipper & slider insert |
| Seam Joining Technology | Needle stitch (Risk of needle fragments) | 20 kHz Ultrasonic fusion (100% metal-free) |
| Length Dimensional Tolerance | ±8.0 mm to ±15.0 mm (Manual stretching) | ±1.0 mm (Bus-synchronized servo drive) |
| Hanger Eyelet Execution | Offline hand punch / manual scissor snip | Inline hydraulic die punch with welded border |
| Personnel Required per 1,000 Units/Day | 5 to 7 Sewing operators | 1 Operator for complete line management |
Converting fabric plies extending up to 1.6 meters in length requires extraordinary tracking precision. Any minor deviation in roll parallelism causes the center zipper to run diagonally, producing warped garment bags that do not hang plumb.
OKUMA CNC centers machining ultra-wide roll shafts, slider insertion guide ways, and cutter anvils to ≤ 0.015 mm tolerances.
All wide-span side frames, zipper pay-off carriages, and ultrasonic sonotrode mounting bridges on the OYANG XG1200 are machined on Japanese MAZAK and OKUMA 5-axis CNC machining centers. Planar machining tolerances of ≤ 0.015 mm ensure perfectly synchronized web tracking, zero edge skew, and a robust mechanical chassis rated for decades of heavy multi-shift operation.
The definitive production standard for garment bags. Delivers 30–50 covers/min with continuous inline zipper feeding, automatic slider insertion, ultrasonic sealing, and hanger punching.

Explore Lace Sewing SpecsA suit cover bag making machine is an automated industrial converting system designed to convert roll-fed non-woven fabrics into full-length apparel dust covers equipped with an inline zipper closure, hanger opening, and ultrasonic perimeter seals.
The OYANG XG1200 continuously pays off nylon coil zipper ribbon, automatically installs the slider pull tab via a synchronized mechanical inserter, aligns the zipper with the center slit of the non-woven web, and welds it securely using 20 kHz ultrasonic sonotrodes without sewing thread.
The OYANG XG1200 operates at a verified speed of 30 to 50 finished garment bags per minute depending on the overall length of the cover, yielding roughly 14,000 to 24,000 completed covers per 8-hour shift.
Yes, cut lengths are digitally adjusted on the touchscreen HMI from 600 mm up to 1,600 mm to support suits, trench coats, and wedding dresses, while web widths are mechanically adjustable up to 1,200 mm unfolded.
Ultrasonic seaming fuses non-woven fabrics molecularly without perforations or needles, eliminating thread inventory costs, puckered seams, and the critical risk of broken needle fragments entering retail clothing shipments.
