Abstract: An apparatus for applying glue to the fibers of material, such as wood and the like, especially to cellulose-containing fibers, in which the fibers are supplied to one end of a substantially horizontal drum and removed from the other end thereof with the fibers being impelled through the drum by impelling elements mounted on a central shaft rotatable in the drum and at the inlet end of the drum. Glue is applied to the material downstream from the impelling elements, and downstream from the region of glue application the material is intensively combed by tapering elements mounted on the central shaft. The glue is applied by radial elements mounted on the central shaft and to which glue is supplied through the shaft.
