Filter Tube Machinery
Meltog is a pioneer for lock seamed spiral tube machinery for the filter/filtration industry. The company introduced its STM200 in the early 1980’s. Meltog was the inventor and patent holder of the now widespread louvering method of producing open area in tubes. For 40 years, the company has held a leadership position offering unrivalled flexibility in seam styles:
– Outside
– Outside Flush (for louvered or corrugated)
– Inside
– Inside Flush

Tool Changing
Through the Meltog ‘Rapid Change Tooling System’, all of the Spiral Tube Machines are able to produce in-line-louvered tubes to standard or customer specification.

Cut-Off System
For Meltog’s STM machinery, producing the tube is only part of the process. The Cut-Off system has to be able to produce repeatable, clean and chip-free tubes without distorting the tube. In order to achieve this, all STM machines utilise a high-speed-rotary shear system.
