Oerlikon Neumag
Optimized tangle unit for BCF yarns

 
The tangent nozzle has been flow-optimized, so that the air pressure can be reduced by approx. 10% compared to the previous version with the same knot strength. Furthermore the nozzle bearings have been improved. The tangling unit saves up to 50% of the energy required for compressed air generation and at the same time leads to even more efficient BCF yarn tangling. As a result, either even higher speeds, or nozzle rings with a higher number of holes can be used, resulting in even more knots in the yarn.
Oerlikon Neumag has equipped various new and old machines with the RoTac3 since its market launch in 2015. For the newer BCF S8, the RoTac³ is part of the standard scope of delivery. The tangle unit is optional for the single-end Sytec One system as well as for the 3-end S+ system.
