The OFC35 is an axial tension proof testing system for small and standard diameter fibers

Proof Tester OFC 35
(PresseBox) ( Vantaa, )
For specialty fibers we developed it further to the OFC 35SF with extended tension ranges for tensile testing and large diameter proof testing using integrated bending wheels to test fiber strength in 8 directions. It is a highly accurate system where the resolution is maintained with multiple tension gauges for different fiber ranges.

During proof testing, the fiber is typically payed off, tested by loading the fiber between two capstans with a particular force and is then taken-up with a dancer. In order to meet the requirements of specialty fibers, special attention has been paid to high-quality take-ups and pay-offs, flexible configurations, quick set-ups, easy operation, and maintenance. A top performance level is reached by efficient servo motors, high accuracy tension sensors, and purpose to special design dancerwhich guarantee effective winding at high speeds. A cutting plan can be keyed in to the unit so that it stops when desired length is reached.

When designing the OFC35SF we have put a special focus on ergonomics and ease of use as well as on safe and comfortable use of the machine. For example, the threading mode and fiber clamp of the take-up make the set-up very easy. The operator then only needs to change full reels in the pay-off and empty reels in the take-up. It is a system that is easy to handle and it fulfills international proof testing standards.
