LABORATORY SIZE SINGLE END DIPPING UNIT FOR MATERIAL & PROCESS DEVELOPMENT FOR REINFORCING YARN AND VALIDATION OF YARN-TO-RUBBER ADHESION

SEDU is a modular system to process a single yarn such that it is fully tension controlled from un-winding of standard bobbins, through dipping, through drying and finally up-winding on bobbins for further handling. The master controller handles multiple stretching zones in regulated tension mode or fixed speed ratio, it controls temperature of the ovens, and it meters and monitors the process in retrievable data files, while conditions can be changed on-the-fly.

It can be used to revamp existing laboratory systems (e.g. Computreater® from Litzler) or be adapted to other machine designs. It can even be proposed as new, typically custom designed installations.

Key Features

  • Modular number of zones, dipping stations or drying ovens – any combination is possible
  • Master-slave drive motor system – any motor can be master
  • Regulated yarn tension or fixed speed ratio, individually selected for every zone
  • Very precise and reproducible process conditions – can be changed on-the-fly
  • Fast stabilization of tensions concurrently in all zones and extremely stable conditions
  • Unwind station with unique tension-controlled yarn buffer for on-the-fly change-over of feeding bobbin
