method and device for cutting slakkenwol

摘要

A process for cutting of a mineral wool web without creating dust as associated with known processes involves cutting with a knife blade (2) which has a peripheral speed in the direction of the movement of the mineral web (1) which is somewhat higher than the velocity of the web. The knife blade (2) has an edge (3) of such a form that it has a cleaving effect as opposed to having teeth which remove chips or particles. IMAGE
