SM Klebetechnik offers customised system solutions for the filter industry

Pressure, heat and chemicals subject filter systems to high stresses. That’s why reliable adhesive bonds must meet high quality specifications, both in the production of filter material and in the filter bonding. SM Klebetechnik’s experts offer straightforward, low-maintenance, reasonably priced systems especially designed for processing adhesives and sealants. The individual solutions improve filter production efficiency as well as filter function.

Material pre-processing systems used in filter construction

A variety of filter media are used in the production of filters, such as non-woven materials, paper or materials made of nanofibres. SM Klebetechnik offers material processing systems and equipment for bonding filter media together.

  • Non-woven coating with hot melt using the spray method (“fibre deposition”)
    When coating non-wovens, the spray method can be used to apply reactive adhesives such as PUR or POR or also non-reactive adhesives such as PO or PSAs. The non-contact application of adhesive subjects application nozzles to less wear because it keeps them from getting plugged up with non-woven material or other particles.

  • Supported bonding
    For the reliable bonding of the filter in the frame or housing while maintaining precise distances.

  • Frame bonding
    With variable-width application nozzles, glue can be applied to frames in flexible widths – for maximum flexibility.

  • Frame sealing
    The systems enable the processing of high-viscosity sealants at up to 200°C.
