Product Description

The NTPFD-330 is a fully automatic machine designed to manufacture square bottom paper bags directly from paper rolls, whether blank or printed. It is the ideal high-volume solution for producing foodstuff bags, shopping bags, and retail carriers.

This machine completes the entire process in one pass: side gluing, tube forming, cutting, bottom creasing, bottom gluing, forming, and final product out-feed. Controlled by an advanced PLC system with a Touch Screen and German KEB Servo Motors, the NTPFD-330 ensures precise bag length control and high-speed production up to 200 bags per minute.

Key Features

1. Premium Component Integration: The machine is equipped with top-tier international components for reliability. It features Italy ZATOR for side gluing, Italy SELECTRA for automatic error correction, and German KEB Servo with SICK photoelectric eyes for accurate print tracking.

2. Hydraulic Material Handling: Unlike manual loading systems, the NTPFD-330 uses hydraulic lifting for heavy paper rolls, combined with an automatic tension control system for smooth unwinding.

3. Quick Size Adjustment: The center clip, drum wheel clamp, and drum wheel mechanical finger utilize a spider synchronous adjustment design. This significantly reduces the adjustment time when changing bag sizes, boosting your daily uptime.

4. Automatic Protection: The system includes an automatic stop function if there is no material, along with an automatic lubrication supply system and a jam alarm system to protect the machine from damage.

FAQ: NTPFD-330 Automatic Roll-Fed Square Bottom Paper Bag Making Machine

Yes. The machine uses a German KEB Servo System combined with a SICK Photoelectric Eye. This allows it to accurately track printed marks on the paper, ensuring that the cut and crease lines align perfectly with your printed design.

We use the Italy ZATOR system for side gluing. This is a world-class gluing system known for precise application, preventing glue leakage, and ensuring a strong bond even at high speeds of 200 bags per minute.

We have engineered a Spider Synchronous Adjustment mechanism for the drum wheel and clamps. This mechanical design significantly reduces the adjustment time compared to traditional machines, allowing for faster changeovers between different bag orders.

The NTPFD-330 comes with a Hydraulic Lifting System for material handling. Operators do not need to lift heavy rolls manually; the hydraulic arm lifts the roll (up to 1300mm diameter) into place automatically, improving safety and efficiency.
