Method and arrangement for improving the runnability of a continuous mineral fibre web

摘要

The invention relates to a method and arrangement for improving runnability of a continuous mineral fibre web. Mineral fibres are produced from mineral melt by using a fiberising apparatus, binder is added to the formed mineral fibres, and the formed mineral fibres are blowed from the fiberising apparatus towards a collecting surface onto which the mineral fibres are collected as a primary web. Optionally the primary web is cross-lapped to a secondary web. The collected primary mineral fibre web or the secondary mineral fibre web is processed at a working level of a first processing unit and conveying the web to a working level of a second processing unit. According to the invention the working levels of the first and/or the second processing units are adjusted to the substantially same plane in order to ensure an even transfer of the mineral fibre web between the processing units.
