The development of the innovative Open Reed Weave (ORW) technology by DORNIER has created the foundation for integrating completely new functions into the weaving process.

System design demands a large technical effort in realizing patterns in the fabric surface. Floating threads that occur on the rear fabric side increase the surface weight. With technical fabrics, the fabric structure leads to an anisotropic surface image which means fabric characteristics are not homogenous in all directions. Fabric strength and stretching behavior are therefore strongly dependent on the direction of activated forces.

ORW technology allows integrating additional threads into the weaving process by using special thread guides arranged between the reed and weaving shafts. Linear drives shift the thread guides horizontally on a profile depending on the pattern. The additional pattern threads create a filling effect on the fabric surface that can be controlled as desired. This filling effect is similar to embroidery and Scherli patterns. ORW technology therefore offers more flexibility and pattern options domestic textile applications (e.g. curtains, tablecloths) and clothing materials.

ORW technology can also be seen as a process for creating multiaxial fabrics for technical textiles.
Arranging two axes driven independently allows weaving additional threads into the plain weave in any diagonal direction as 3rd or 4th thread systems. This adapts the position of the diagonal threads to the direction of active forces.
Apart from the option of integrating additional thread systems in the plain weave across the complete fabric width, ORW technology is especially suitable to do this partially in order to integrate reinforcements required for specific fabric areas.
Modular integration of the ORW unit retains the full productivity and unrestricted application spectrum of the weaving machine.
