Fine openers ensure that coarse fiber tufts are gently opened into smallest tufts or even single fibers.
Featuring two large feed rolls and an opening roll with spikes, the Trützschler reserve trunk TBL-FB is the first choice for the additional opening process. It works without clamping, thus minimising fiber strain.
Due to the high requirements of bleached cotton, other natural fibers such as flax, kenaf and hemp as well as recycling fibers, the special Fine Opener TBL-FO is used in these applications.
In some cases the fine opener allows the use of roller cards with less carding points. This reduces investment costs and increases productivity. For selected end products, even direct bonding is possible without a roller card.
