ABSTRACT OF THE DISCLOSURE A system for metering binders for application of adhesives to chips, fibers and the like for manufacture of composite panels, has a supply vessel, a withdrawal pump with a drive and a control loop for speed control of the withdrawal pump. A filler pump fills a first measuring cup with adhesive through a supply line. After complete filling the cup is connected with a suction connection of the withdrawal pump and simultaneously a connection is effected between the supply line with a second measuring cup. The emptying time of the measuring cups is sensed and compared as actual emptying time with a command emptying time which is determined based on the desired volume of adhesive per unit time. Upon exceeding of the command emptying time, the throughput rate of the withdrawal pump is increased and upon falling below of the command emptying time, the throughput rate is decreased.
