LS-7161A Automatic Hanger Loop Attaching Machine: Ironing, Cutting & Sewing in One Workflow
The LS-7161A Automatic Hanger Loop Attaching Machine is a dedicated machine for producing and attaching hanger loops (also known as collar hanging straps) — the small strap or ring commonly found inside a jacket’s collar, allowing the garment to be hung on a hook without a traditional clothes hanger. The machine integrates the entire process — ironing, cutting, folding, and stitching — into a single continuous operation, fully replacing a multi-step manual process.
What Is a Hanger Loop, and Why Does It Need a Dedicated Machine?
A hanger loop is a small but very common detail found on most jackets, down jackets, and windbreakers — typically positioned at the center-back inside the collar, used to hook the garment onto a hook instead of a traditional hanger, particularly useful when hanging garments in public spaces or tight areas.
From a production standpoint, making a hanger loop seems simple but actually involves several small steps: cutting the tape/fabric strip to a standard length, ironing it flat, folding the edges, then sewing it onto the collar. Done manually, each step takes time and is prone to size inconsistency between individual loops.
How the LS-7161A Solves This Operation
How the LS-7161A Solves This Operation
The machine integrates 4 standard features, processing the entire workflow in a single operation:
- Ironing device: flattens the tape/fabric strip before cutting and sewing, ensuring the finished hanger loop isn’t wrinkled.
- Integrated hot-and-cold cutting knife: cuts the tape/fabric to a standard length; the hot-cut mode seals the edge of synthetic material to prevent fraying, suited to materials prone to unraveling.
- Rear feeding mechanism: automatically feeds the tape/fabric into the correct processing position without requiring manual operator alignment.
- Joint detection (probe test): automatically detects splice joints in the raw tape/fabric material, avoiding the use of a jointed section that would reduce the finished loop’s quality.

Real-World Applications
The machine is suited to the hanger loop attaching operation on most collared outerwear:
- Jackets, down jackets, and windbreakers of all types.
- Sportswear jackets and uniforms requiring a hook/hanger loop.
- Any garment requiring a hanger loop detail in high volume with consistent sizing.
Which Factories Should Invest in the LS-7161A?
- Export-oriented jacket and down-jacket manufacturers with high production volume and a daily-repeated hanger loop attaching operation.
- Factories currently experiencing a high defect rate (inconsistent loop size, uneven quality) from a multi-step manual process.
- Factories looking to optimize labor cost for a support operation that, while secondary, consumes significant time — like preparing and attaching hanger loops.

Frequently Asked Questions
Can the LS-7161A cut different types of tape/fabric materials? The machine is designed to process strip material within a 53–80mm width range before folding, producing a finished loop 5–16mm wide and 43mm or longer. Consult a technician if your material falls outside this range.
How does the joint detection (probe test) function work? The system automatically detects sections of tape/fabric with a splice joint (from joining material rolls during production), removing the jointed section before it’s cut into a hanger loop, avoiding an impact on the finished loop’s durability and appearance.
Is this machine suitable for small-to-mid-sized factories? With an output gain of roughly 300% compared to manual handling, the machine is best suited to factories with sufficient volume at the hanger loop operation to fully utilize its capacity. Small factories should assess actual volume for this operation before deciding to invest.
