Cold needle perforation

Short description

Conical needles pierce the web material (e.g. paper, thin metal foils, PE foils). The grooves in the counter-roller line up perfectly with the needles.

Products

  • Spiked roller
  • PM 10

The needles produce holes with a conical profile.

The water-permeability is increased with paper materials, and the air-permeability with PE foils.

No material loss

The holes can partly close again, if pressure is applied to the web.
