Abstract:
1. An apparatus for adding glue to a flow (L) of loose wooden material, comprising: a tubular body having at least one inlet and one outlet for the wooden material, distanced one from the other in a direction corresponding to an axis of the tubular body; means for pneumatically transporting the wooden material at least from the at least one inlet to the outlet of the tubular body; a mixer element which revolves internally of the tubular body, which mixer element is axially extended between the at least one inlet and the outlet; one or more nozzles predisposed in proximity of the at least one inlet of the tubular body which one or more nozzles issue glue to be added to the flow of (L) of wooden material, wherein: the tubular body exhibits at least one inlet for a flow of air from the means for pneumatically transporting; the at least one inlet of the wooden material and the at least one inlet of the hot air are predisposed in such a way that the flow of wooden material enters the tubular body in a transversal direction to the axis of the tubular body and the flow of hot air enters the tubular body in an axial direction there-to; the at least one inlet of wooden material is located on a lateral surface of the tubular body and is at least eight-tenths as wide as a maximum width of the tubular body at a point where the at least one inlet is located, in a transversal direction to the axis of the tubular body; the at least one inlet of hot air is located at an end of the tubular body and is equal to a section of the tubular body perpendicular to the axis thereof; the at least one inlet of hot air and the one or more nozzles for the glue are located upstream of the at least one inlet of wooden material, where “upstream” is taken to mean with reference to an axial direction of an advancement direction of flow of wooden material from the at least one inlet to the outlet.
