Abstract

The technical problem of the invention is to improve the wetting of wood fibers with a binding agent. This technical problem is solved according to the present invention by a device for wetting wood fibers (10, 109) with a binding fluid, with a transport pipe (16, 105) for transporting the wood fibers (10, 109), with a fan (14, 106) for generating a transport air current, with a guide tube (17, 109) connected to the transport pipe (16, 105), with a fan (20, 110) for generating a conveying air current in the guide tube (17, 109), with means (27, 12) for supplying the binding fluid in the guide tube (17, 109). The invention also relates to a process for wetting wood fibers with a binding fluid.
