Abstract
A device and method for elutriating and gluing wood chips. At least one elutriating apparatus is used to fractionate the wood chips into at least one coarse chip fraction and one fine chip fraction. The elutriating apparatus has a fall duct and is designed so that the chip fractions pass through different gluing regions in the fall duct. At least one gluing apparatus is provided in order to glue the chip fractions in the gluing regions. Thus, the chip fractions can be glued in a common apparatus specifically with a glue amount adapted to a particular average chip size.
