The tape is bonded by spot welding in an argon environment.
The tension is adjustable in the range from 1500 to 10000 N.
The SPECTA S12 strapping head is designed for use as part of a strapping machine for the purpose of tensioning and fastening steel strapping tape.
The strapping head of the SPECTA VS12 model is suitable for packaging medium-weight goods (metal, stone, wood or glass).
The SPECTA VS12 features state-of-the-art drive and control technology along with the latest version of tungsten gas shielding technology (TIG technology).
The completed strapping can only be opened with the help of special shears for steel tape.
The strength of the welded joint is approximately 90% of the tensile force of the tape (depending on the quality of the tape and its dimensions).
The tension can be adjusted in the range from 1500 to 10000 N and is selected according to the type of product to be packaged.
All operations of the strapping head are performed by three pneumatic motors and five pneumatic cylinders. The consumption of argon when using a cylinder with a capacity of 50 liters is 10000 welds. The welding electrode should be resharpened approximately 100 times.
