The unit is designed for the production of “bottle-neck” type big-bag liners and suspended liners.

Technical specifications of the line:

All machine operating parameters (welding, cutting, pneumatic drive operation) are adjustable.
Welding and scrap-cutting cycle time: up to 10 seconds.
Machine dimensions (length/width/height): up to 2200 x 500 x 2500 mm.
Machine weight: up to 150 kg.

Components and operating principle

A positioning unit for a pair of welding-and-cutting assemblies and a pair of backing plates is mounted on the machine frame.
The positioning unit secures two identical welding-and-cutting assemblies to the frame and allows for their transverse movement to produce inserts of various sizes.
Each welding-and-cutting assembly performs a U-shaped weld and cuts out the waste material. The U-shaped weld is produced by a continuously heated tool, creating a weld width of 8–10 mm. The internal U-shaped contour is cut out using a thermal-impulse tool.
The tools on each assembly are controlled independently.
Vertical movement of the welding-and-cutting assemblies and the application of welding force are driven by a pneumatic system.
Welding parameter control: welding temperature is regulated by a temperature control device, while welding force and duration are managed by the pneumatic system’s control unit.
Thermal cutting parameter control: power supplied to the heater and heating duration are regulated by the thermal-impulse control unit, with parameters set digitally.

The equipment is easy to transport, install, and maintain.
