3. Kirschner beater:
In this type of beater, instead of beater bars, pinned bars (pinned lags) are secured to the ends of the cast-iron arms. The relatively high degree of penetration results in a good opening. Kirschner beaters were therefore often used at the last opening position in the blow room line. Modern Kirschner openers are often designed as closed rollers rather than three-armed beater units. The design is simpler and the flow conditions are more favourable.
