Automatic welding machine MK7

Fully automatic welding machine for installation in your filling line.

Your flexibility is increased by processing various kinds of packages in differing dimensions on the same machine.

The stationary welding process guarantees that the high quality requirements made of the welding seams are fulfilled.

Thanks to the modular set-up, the machine is quickly available for you.

Individual versions can be produced according to your specific requirements and wishes.

Packages:
You can process various kinds of packages in differing dimensions and materials:

• Flat bags in differing dimensions
• Bags with a side fold
• Boxes with inliners
• Drums with inliners

Expanding device:
The expanding device depends upon your kind of package.

• Simple expansion for flat bags
• Double expander for side-fold bags

Welding technique:

• Pulsed welding procedure with single or double welding seam
• Welding jaw length: 500 - 900 mm
• Various monitorings of the heating tape can be installed
• Increase of production output by water cooling as an option

Head area air removal:

• A suction probe automatically immerses into the package and sucks the excess air from the head area of the bag
• Automatic cleaning puts any product which may have been sucked off back into the bag
• After the air evacuation, the package can be provided with protective gas

Technical data:

• Electrical connection:3 x 400VAC; N; PE; 50 Hz; 25 A
• Pneumatics:5bar
• Welding voltage:48VAC
• Control voltage:24VDC
• Weight:approx. 700kg
• Output:2-6packages / minute

Contamination free filling station

With this filling unit you can feed and fill in accurate to a gramm.

The application of an endless liner guarantee a dust and contamination free filling.

The thermal separation prevents dust particles from leaving the endless liner.

Our approved welding system guarantee a high quality of welding seams.

The set-up of the welding jaws guarantees a maximum retention of the heating elements, even in rough production conditions.

The integrated deairing and ventilation system increase the product protection.

The mobile construction of the filling unit allows the possibility of application in different production lines.

Individual versions can be produced according to your specific requirements and wishes.

Vibrating Tube Feeder

Welding machine ISPV - 3

Welding machine to close your boxes with inliners, drums with inliners or bags.

The air evacuation before the welding ensures that the excess air is removed and the packaging can be closed properly.

The high reliability of the welding seams is guaranteed even with products with a large amount of dust.

The pneumatic jaw closing generates a high welding pressure and is thus particularlysuited for coated foils and paper bags.

The set-up of the welding jaws guarantees a maximum retention time of the heating elements, even in rough production conditions.

Your production output can be increased by water cooling of the welding jaws.

Individual versions can be produced according to your specific requirements and wishes.
