Solutions for IDY production - Oerlikon Barmag - Oerlikon Textile

Godets
Oerlikon Barmag godets are custom-developed components for manmade fiber production. Continual
innovations in the areas of design, process, and safety fulfill the ever increasing demands of ever faster
processes and higher denier processes. Our godet families are renowned for their countless productive
details. Their technological properties make it possible to achieve outstanding results in a huge variety
of processes.
High productivity and competitiveness are ensured thanks to
the following basic requirements:
- Robust design;
- Achievable high process speeds;
- Low-energy consumption for HF godets;
- Reduced maintenance times;
This all makes the Oerlikon Barmag godet family the
suitable choice for all manmade fiber processes.
Cold Rolls
With the increasing amount of yarn ends per position, a
smooth yarn path is becoming more and more important. To
ensure a proper pretension of the yarn, the Oerlikon Barmag
take-up for more than 6 ends uses a cold roll duo with
220mm diameter.
HF godets
To fulfill the special demands made on godets in industrial
yarn spinning processes – significant drawing and shrinkage
forces plus utmost uniform temperature profiles – our godets
have been optimized both for conventional industrial yarn

processes and HMLS processes. The modular godet series
is tailored to the latest industrial yarn processes and covers
all possible product ranges up to 24 ends or a denier range
up to 18,000 den per position. With these components, every
take-up is tailored to the customer’s demands. High-speed
bearings with long service lives, using the Barolub lubrication
system, and low power consumption are further benefits.
Lower energy consumption
Compared to other godet heating concepts, the HF principal
has 20% lower power consumption than 50-Hz heat pipe
systems. This results from the skin effect, which directly
takes the energy to the location that has to be heated.
Furthermore, the HF technology allows a significantly more
compact godet design. For the same power output, the
godet shell diameter can be reduced by 40 mm.
For this reason, the HF godet family easily fulfills the requirements
of the e-save label. The energy savings reach
20-30%, even with high numbers of yarn ends per position.
Lower energy consumption also reduces the investment in
the A/C system, power distribution units, etc. This is further-
