New Trützschler Card TC 11 to figure at Barcelona

Trützschler Spinning will introduce a newly-developed card at ITMA in Barcelona, the TC 11. Card development is an ongoing process with Trützschler. New findings and ideas are immediately integrated in the current production. However, traditionally a larger step is taken on the occasion of ITMA in Europe by introducing a new card type with clearly improved production and quality parameters. In Barcelona, this will be the Trützschler Card TC 11.

The new card stands for low capital expenditures and production costs. This was made possible by a larger carding area and unprecedented accuracy. The result is a 30-40 per cent increase in productivity.

Naturally, the established roll diameters of the predecessor machines have been adopted. The same applies to the cross-section of the carding elements and flats.

The capital expenditures for the cards, the building and the filter system are lowered. Increased card production means fewer cards. This results in a reduction of capital expenditures. Therefore, the performance per sq. metre building area increases. This means lower investments for new buildings. Or it allows a carding capacity increase in the same space by replacing the cards.

Operating costs are reduced due to lower capital costs, lower power consumption and smaller filter systems. The specific power consumption is at the lowest level. With the TC 11, savings of approx. 20 per cent electrical energy for each kilogram carded sliver are realised. The filter system is also more compact and uses smaller fans. Thus, it uses less electrical energy.

The machine, completely new designed, takes just one look at the structural design to reveal the new concept. The card frame supports only the drum directly. Thermally induced changes to settings are reduced. The sensor and software based T-Con system is of course also an integral part of the Card TC 11.

During development it quickly became obvious that the required accuracy cannot be achieved with conventional flats. Therefore, the Trützschler MAGNOTOP system is exclusively used for the TC 11.

In addition to increased production, these measures also result in quality improvement. Never before was card sliver cleaner, free of neps and uniform.

The man-made fibre card TC 11-S was simultaneously developed with the TC 11. This machine is equipped with special clothings and features one needled licker-in with increased diameter. All fibre-carrying elements are made of stainless steel.

Trützschler Draw Frame TD 8

Trützschler Spinning will also introduce a new draw frame type. Even at first glance the new design of the Trützschler Draw Frame TD 8 is obvious. The integration of a new drafting system and a new filter resulted in a new casing.

The drafting system is characterised by increased accuracy. This benefits sliver evenness. Top and bottom rolls are in a precise fixed position to one another. As is customary with Trützschler, adjustment is carried out parallel. Cleaning bars and pressure bar, made of hardened stainless steel, do not have just the usual thin coating.

Sensor reliability and accuracy is decisive for the control. Meanwhile, the newly developed input sensor Disc Leveller TD-DL has passed all field tests with flying colours and is now part of the standard equipment of the TD 8. Sensor and groove plates feature double bearings, with one bearing below and one above the plates. The axle is firmly anchored and does not need to rotate. Both these measures result in improved measuring accuracy and many years of long-term reliability.

The quality monitoring system Sliver Focus is also equipped with a new sensor. It is characterised by extraordinary robustness and reliability.

For even more accurate and dynamic levelling behaviour, the sliver feed creel is mechanically decoupled. The new compact sliver feed Servo Creel is equipped with its own drive. The levelling motor works more dynamic since it no longer needs to accelerate and decelerate the creel. Another advantage is the possibility of continuous and sensitive adjustment of the tension draft between the creel and draw frame. All it takes is a touch on the large colour touchscreen.
