With conventional solutions, an error also stops production on the other side. Instead of a single efficiency of 85 %, in reality only 72 % is realized, because the single efficiencies have to be multiplied. Efficiencies of over 90 % can only be achieved in practice with the Trützschler TD 9T. Thus, depending on the size of the installation, 1-2 drafting heads can be eliminated.
If an uneven number of drafting heads is required, a single draw frame can be added to the TWIN draw frames. This reduces investment and operating costs compared to a conventionally required additional double head draw frame. The strict separation of the drives allows maximum flexibility: Two different materials or two different sliver counts can run side by side on one machine.
Large can diameters such as the JUMBO CAN or 1000 mm are becoming more and more popular due to their economic advantages. For smaller can diameters, the TD 9T and the TD 9 are now also available for 600 and 900 mm can diameters. Thus, the advantages of the machine concept can be applied here as well.
