Abstract

In a method for the continuous addition of glue to a mixture consisting of wood chips, wood fibres or the like, the mixture is moved helically, in the form of a ring of mixture, through at least one glue-applying zone of a mixing container where glue is supplied to the mixture substantially radially from the inside of the ring of mixture. In order to achieve a particularly satisfactory distribution of glue over the chips or fibres with the use of little energy and so little destruction of the chips, the glue is very finely atomized in the space situated inside the ring of mixture and is supplied to the ring of mixture largely radially. For this purpose, glue nozzles, to which glue can be supplied under pressure by a glue proportioning pump, are mounted on the shaft of the mixing container.
