Machinery program

DOA manufactures complete production lines for fiber sheets and thermal bonded non-wovens. The design is based on our own numerous patents permitting many unique solutions with regard to technique and technology.


Sheet forming machines of DOA work on aerodynamic principles and allow the production of random sheets. Such a sheet shows even fiber distribution in all directions and good mechanical properties accordingly.


At a certain sheet weight, a fiber orientation in the 3rd dimension may also be achieved - that is especially important for sheets with distinctive features of volume and with increased elasticity of compression.


The delivery program contains:

  • Bale Opener and Fiber Blending Plants

  • Sheet Forming Plants

  • Scattering Devices

  • Needle Felting Machines

  • Thermal Bonding Machines

  • Complete Nonwoven Lines
