Get PriceThe nip angle describes the angle the stationary jaw plate and the pitman make with each other. The exact value of this angle isn't quoted or even determinable due to curvature in the jaws themselves but what is important is how wide vs. narrow it is. Wide nip angles can tend to expel material as the jaw closes as a large ball might
