Machine Description
The machine is used to produce single-mouth open roll bags commonly used in automatic bagging machines (Auto Bag Packaging Machines). As an important part of DMS Converting’s Roll-to-Roll solutions, this perforation machine offers cost advantages to investors with its compact design.
DMS Converting’s Pre-Open machine is specially designed for the production of single-mouth open roll bags used in automatic bagging machines. Operating roll-to-roll, this machine provides significant cost and space advantages to investors with its compact structure and high precision.
Thanks to its automatic mouth opening feature, bags are produced ready for filling and sealing processes, reducing labor costs and increasing efficiency on the production line. The Pre-Open machine offers high-speed, stable, and continuous production capabilities, making it an ideal choice for companies seeking modern and economical solutions in the packaging industry.
Machine Specifications
The unwinding unit features a motor-driven dancer system supported by a linear potentiometer sensor, operating with a PID-controlled tension system.
Film tension is continuously monitored and kept stable, effectively preventing material tearing and rewinding errors.
- When the film runs out, the end-of-material sensor is activated and automatically stops the system.
It ensures operational safety and saves time.
- Main rollers controlled by an AC drive enable adjustable production speed and product sizing.
Automatically opens the top layer of the perforated bag.
Makes it ready for use in automatic bagging machines.
During machine start/stop operations and emergency situations, visual alerts (warning lights) and audible alerts (buzzer) are activated.
This helps prevent operator errors and ensures a safe working environment.
Production outputs are recorded on a daily, weekly, monthly, and yearly basis.
This facilitates cost tracking, performance evaluation, and efficiency analysis for the operation.
The motor-driven unwinding unit is built with a dancer system supported by a linear potentiometer sensor, operating in coordination with a PID-controlled tension system.
Tension imbalances that may occur during winding are automatically compensated, ensuring smooth and consistent film handling.
Who should buy it?
- Manufacturers supplying packaging to companies with automatic bagging machines (Auto Bag Packaging Machines).
- Investors seeking cost and space advantages in the plastic bag and pouch sector.
- Packaging producers with automatic bag filling and packaging lines.
