HSM-621/ABL: Automatic Double Needle Belt Loop Attaching Machine – The High Speed Belt Loop Sewing Solution for Garment Factories

HSM-621/ABL Automatic Double Needle Belt Loop Attaching Machine was developed as a breakthrough solution. This advanced jeans belt loop sewing machine fully automates every step—from cutting and edge-folding to bartacking. It helps garment factories completely eliminate production bottlenecks while ensuring uniform quality across every single product. In the production of jeans, khakis, or trousers, attaching belt loops manually may seem minor, but it is extremely time-consuming and prone to misalignment.
Outstanding features of the HSM-621/ABL Automatic Belt Loop Attaching Machine:
1. 100% automated, fully enclosed “Cut – Fold – Stitch” operational workflow

As the best automatic twin needle belt loop attaching machine for jeans, this system requires just a simple activation. Once started, the machine automatically pulls the belt loop tape, cuts it to the programmed size, and neatly folds both edge ends before performing the final bartacking onto the waistband. This fully enclosed workflow completely eliminates time-consuming manual steps like edge-ironing and folding.
2. Outstanding speed, optimizing labor costs
Thanks to an advanced feeding mechanism and upgraded pneumatic cylinders, the HSM-621/ABL high speed automatic belt loop sewing machine for garment factory operations takes only 1.2 to 2 seconds to complete a finished belt loop. A single machine can achieve productivity equivalent to 3 traditional manual sewing operators, helping business owners optimize labor budgets and accelerate export order deadlines.
3. Belt loop setter machine has Flexible size adjustment according to product styles

Equipped with an intelligent gauge holder and cutting knife system, this machine allows technicians to easily adjust the belt loop’s cutting length and width. This outstanding flexibility enables garment factories to quickly switch this needle belt loop attaching machine between different product lines, from thick denim jeans and khakis to thinner trousers. It is truly the ultimate high-speed belt loop attaching solution for modern production lines.
4. Smart error-detection sensor system
To ensure smooth operation, the HSM-621/ABL model integrates advanced electronic sensors. The machine will automatically stop and alert technicians during common issues like running out of tape, thread breakage, fabric jams, or needle breakage. Consequently, this feature minimizes your rework rate and extends the lifespan of the machine’s components.
