Machine Description
This automatic double-stitch paper bag machine, combining two semi-automatic modular lines (A+B), combines flexibility, efficiency, and a high degree of automation. Designed to meet the diverse production requirements of double-stitch paper bags, this machine demonstrates strong market adaptability through its wide range of applications, including luxury goods, apparel, gifts, and shopping paper bags.
By utilizing double-stitch forming technology, high-speed, high-precision production processes, and an intelligent control system, the machine reduces costs, improves efficiency, and optimizes quality. Its modular design allows for flexible adaptation to diverse production needs. Its environmentally friendly features align with current trends in green production, making it a leading upgrade option for traditional paper bag production equipment.
Machine Features
1. Flexible design ensures you running either single-sheet or 2-sheet-pasting production in 1 machine line, with separations of the line or in full line.
2. High precision, high production, Low requirement in operators’ experience and low wastage, are well-known features of machines from Champion Machinery.
3. It is widely applicable due to high productivity and easy adjustment.?It can?be applied to the production of small, medium and large or customized two-sheet?paper bags in small, medium or large quantities, and to production of high-level two-sheet?paper bags?with?high requirements for?technology, precision, appearance?and quality,?and two-sheet?/ sheet-feeding paper bags with complex structures;?and can also be applied to the mass production of ordinary sheet-feeding?and two-sheet paper bags;?
4. It can also be applied to the mass production of ordinary sheet-feeding and two-sheet paper bags;
5. Some time consuming setting of the machines are designed with computerized control, and size changing time is greatly decreased, and servo motors join in production motions, also makes machines perform fast and accurately. Setting of the machine thus is much easier.
6. Fresh operator friendly design and programming, ensure you run production stably, fast in size changing, and confident in investing in your business.
