Trützschler IDF 3 Can Changer Becomes Game Changer

The Can changer in the new Trützschler integrated draw frame IDF 3 has become a game changer, by offering accelerated Can change times and improved productivity, while also providing a range of innovative features that give customers even better quality, efficiency and handling.

According to Trützschler, although there were some doubts when the IDF first hit the market twenty years ago, but it has now demonstrated its positive impact on short spinning processes.

“Two generations of this machine have already delivered valuable performance improvements for our spinning customers worldwide. And our innovators have now successfully created the third generation; the new integrated draw frame IDF 3,” Jörg Schmitz, Senior Expert, R&D Spinning Preparation said.

Trützschler’s technical experts decided it was time to give the IDF a turbo boost by adding components and features from other areas of its draw frame portfolio, including its popular autoleveller draw frame TD 10.

First, the team adapted the precise, robust measuring devices, DISC LEVELLER and DISC MONITOR to fit the specifications of card and IDF 3. So, now the resulting IDF DL and IDF DM interact perfectly with the existing 1-zone drafting system, which results in more homogeneous slivers and higher yarn quality.

“Switching to the IDF DL and IDF DM system instead of the previous measuring funnel adds more benefits than advanced detection of sliver deviations. The new system also works entirely without compressed air, which reduces operating costs,” the German company also said.

In addition, the IDF 3 make-over, includes a complete redesign of the drafting zone, in line with all Trützschler drafting systems, which further stabilises the drafting process and significantly improves the yarn imperfection total ‘IPI’ for recycled fibres and raw cotton and also while also blending with synthetics.

Improving the IDF is only possible if innovators also look at the card and Can changer, because there is huge potential, if the interaction between the three elements are optimally balanced. This is particularly true for the direct spinning process, with its small Can sizes.

Each time a full Can is replaced by an empty Can, the delivery speed of the card and IDF needs to be drastically reduced, and this slows down the production process.

“Every second saved from the Can change process, adds to the overall productivity. In this context, the Trützschler team optimised the Can changer to save its customer’s valuable time. The delivery speed of the IDF 3 stays at the high level of 300 m/min during Can changes, which increases efficiency by 3 percent,” Trützschler added.

In order to ensure that machines are easy to operate and offer good accessibility to enable accurate machine settings and effective maintenance, the IDF 3 is designed to open directly towards the operator. This makes it easy to reach all of the adjustment points within the working area.

Thanks to Trützschler’s QUICK START autopiecing function, operators do not need to open the drafting unit. Instead, they simply insert the sliver end into the IDF DL, which saves up to 60 seconds during each piecing.

Depending on the number of piecing processes performed, this saved time quickly adds up to a significant increase in productivity. Trützschler’s technicians have also improved the pressure adjustment on the IDF 3, by adding an easy-to-reach digital pressure manometer.

This makes it possible to precisely set the pressure and directly monitor limits on the drafting system via the display screen. The IDF 3 can also be configured with the exclusive Trützschler features T-LED, SMART TOUCH and RFID to further enhance handling.

“Our third generation of IDF proves that you really can have it all. Customers benefit from better quality, higher efficiency and easier handling,” Trützschler concluded by saying.
