Higher productivity, lower costs

The TCO 21XL works with 12 heads, reducing conversion costs per kg. It provides 50 % more productivity while taking up 25 % less space. Space savings in the critical direction inside the mill. Mill width matters:

  • 30% less building width for same amount of combing heads

Superior quality on 12 heads

High performance drafting even for 12 slivers
  • Higher doubling of slivers
  • Pneumatic loading of top rollers, with automatic limit monitoring
  • Top roller bearing for lowest process temperature on the drafting system
  • Self adjusting top roller lap monitoring

Noil always under control

ONLINE NOIL MONITORING: The new function provides a solution to one of the major challenges our customers face
  • Being able to recognize and react to fluctuations in the raw material
  • No unnecessary processing costs in the downstream process
  • Less waste: raw material savings
  • System references the noil via the output measuring system TCO-DM and the lap weight
  • Display of longterm fluctuations i.e. raw material changes, or other process disruptions in preparation

By decoupling the drives with 2TWIN DRIVE and DUAL DRIVE, the TCO 21 is the only comber on the market with the option of changing the detaching curve. This means that accelerations can be adapted to production requirements during pilger

Piecing point setting made easy

Only Trützschler combers feature an automatic and thus clean setting of the piecing point.


Additional curve, optimized for perfect yarn results even at high nip rates.

The curve visualizes the pilgrim step movement of the detaching rollers.


Automatic piecing point optimization without a single laboratory test for perfect sliver and yarn CV values.

Perfect yarn quality thanks to COUNT MONITORING and COUNT CONTROL

COUNT MONITORING – standard on the TCO 21XL

Quality control through individual limit values for count variations - visualized by T-LED. If the DISC MONITOR sensor detects that a limit value has been exceeded, the machine issues a warning and switches off.

With integrated spectrogram analysis for higher quality.

In the sliver delivery area, the DISC MONITOR ensures permanent sliver monitoring. Every meter of sliver in the can is checked.
COUNT CONTROL – optional leveling

If COUNT MONITORING detects a deviation in the sliver count, COUNT CONTROL reliably levels it on the drafting system. The lap tension remains unaffected, ensuring constant combing quality.

The result is a permanently constant sliver count for first-class yarn quality.
