Abstract:
1. A system for applying glue to fibers for making fiberboard, the system comprising: a fiber supply having at least one fiber-supply conduit using air for fiber transport and opening into a fiber-discharge conduit via a fiber-deflection conduit, a chute downstream of the fiber-discharge conduit, a glue applicator having spray nozzles for spraying the fibers that emerge from the fiber-discharge conduit and enter the chute with droplets of glue, a collection device downstream of the chute, having an air-permeable belt for catching and, if necessary, conveying away the fibers, an upwardly open suction box directly underneath the belt for drawing air and fibers from the chute down through the belt and thereby depositing the fibers on the belt, the suction box having a cleanout port closable by a closure element, a suction line connected to the suction box for withdrawing air therefrom and pulling the fibers down onto the belt and drawing some of the fibers through the belt into the box, and a cleaning conveyor separate from and below the suction line and serving for collecting the fibers that enter the suction box through the belt and for removing the fibers from the box through the port.
