The IDF 2 also introduced the sliver loop storage. This driven deflection roller levels the sliver loop by means of an integrated light barrier, resulting in perfect synchronisation between card and IDF. The levelled loop permits high change speeds. This ensures a higher efficiency at the card, especially when using small rotor cans. The combination of Truetzschler cards with IDF 2 gives customers an advantage, because they produce a thin, stable web which is perfectly suited to be drawn directly to the desired sliver count, at highest production rates and lowest drafts.

The IDF 2 has been established on the market for seven years. The advantages of the system are now recognised by the entire professional community, competitors and customers. Initially, the shortened process was only used with 100 percent cotton, preferably from the recycling sector, but today it is no longer limited to this. The system is successfully applied in the processing of 100 percent raw cotton and other materials. It thus offers an answer to the requirements of customers with regard to increasing and necessary flexibility in the production process.

The handling of the IDF has also been improved. For example, there is now a retention lock that prevents the cover of the IDF from always having to be opened completely during the piecing process. Similarly, the use of maintenance-free deep groove ball bearings entirely eliminates the need for relubrication at the delivery rollers: The number of lubrication points is thus reduced to four. The self-adjusting lap monitoring of the top rollers, already known from the draw frames, has now also found its way to the IDF. There is no need to readjust after grinding intervals and changed settings.
