DGR-ⅡA Notched Closure Sealless Joint Type Automatic Steel Strapping Machine Head

The automatic steel strapping head is the core part of an automatic steel strapping machine. Here is how it works:
1. When the strapping dispenser delivers the steel strapping to the automatic steel strapping head, the strapping feeding roller in this sealless automatic steel strapping machine head helps to send the steel strip to the steel strapping track which encircles the products to be strapped.
2. When the steel strapping forms a full loop around the products, the steel strapping machine starts to move toward the products and retrieve the steel strapping when it moves.
3. When the steel strapping overlap touches the products,  the automatic steel strapping machine head will stop moving forward, it will press on the steel strapping and tensions it until the steel strip bands the products tightly.
4. The sealless automatic steel strapping machine head notches on the steel strapping overlap until it’s connected via 3 pair of notches during automatic strapping, no additional medium needed in the automatic strapping process, the connection strength of this sealless notching joint is about 80% of the steel strapping itself.
