Dual-Channel Bag Making Machine
Equipment Intro & Key Metrics
The double-channel bag making machine is designed for the automated processing of plastic films (or composite films), achieving continuous production of "fixed-length sealing & cutting + winding into rolls." Widely used in the packaging industry, it converts continuous rolls into finished plastic bag rolls through unwinding, sealing/cutting, pulling, and winding processes.

Industry Pain Points
High-Frequency Position Offset
In high-speed production, synchronization between film pulling and the cutter is difficult to maintain, leading to cumulative errors in sealing and cutting positions.
Severe Tension Fluctuations
During unwinding and winding, dynamic changes in roll diameter can lead to inaccurate tension control, causing film stretching, deformation, or wrinkling.
Complex Wiring and Interference
Traditional multi-axis linkage involves tedious wiring. In industrial environments with strong electricity, pulse signals are susceptible to electromagnetic interference.
Difficult Remote Maintenance
Traditional equipment lacks IoT capabilities, making it difficult for manufacturers to perform rapid remote diagnosis or upload production data for cloud management.
FLEXEM Solution Architecture
FLEXEM provides a highly integrated automation solution for double-channel bag making machines. The hardware layer uses the FL8 Series high-performance PLC (with FR series expansion modules) as the control core, connected via EtherCAT to FV3S-R1 Series servo drives. The HMI features the FE6400WE 10.1-inch HD touch screen, supporting tag communication and IoT functionality for high-speed and stable operation.
Core Advantages
Electronic Cam Sync Control
Utilizes electronic cam technology to guide the cutter and film pulling based on a virtual master shaft position, ensuring consistent sealing and cutting even at high speeds.
Dedicated Tension Function Blocks
Built-in unwinding/winding function blocks provide closed-loop control in speed and torque modes based on dancer feedback, suppressing tension fluctuations during speed changes.
EtherCAT Bus Architecture
The entire system adopts a bus-based solution, significantly simplifying wiring and enhancing real-time data transmission and anti-interference capabilities.
High-Performance IoT HMI
Equipped with a high-performance CPU for smooth visuals and IoT capabilities for remote program updates and status monitoring, greatly improving maintainability.
