Ask The ExpertHi Sylvia, I'm testing Kevlar yarn and I'm getting jaw breaks, what gripping solution can you recommend?
Answer
I would recommend you use our pnuematic horn grips with smooth metal surfaces. Other jaw face surfaces will cause premature breaking (see BS EN ISO 2062;1995).
Remember you will need to adjust the operating airpressure for the type Tex/breaking force of the yarn you wish to test.
