The line (4) intended for applying glue to a workpiece having a finger-jointing profile at the end face and supplying glue to an application comb (1) to be operated in accordance with the working cycle of a finger-jointing plant forms, via a branching point (5), a through-connection with two supply branches which are identical to one another and each of which consists of a metering cylinder (8, 9), connected to a feed line (12, 13) for glue, and of a pneumatically controllable control cylinder (10, 11) which can be operated by a directional control valve (18, 19). The metering piston (8', 9') of each metering cylinder (8, 9) is connected via a piston rod (10", 11" ) to the control piston (10', 11') of the associated control cylinder (10, 11), such that the metering piston can be moved pneumatically between a first position, in which there is a through-connection between the feed line (12, 13) and the application comb, and a second position, in which this connection does not exist. By means of a primary control system, the two directional control valves (18, 19) are cyclically activated in succession in such a way that the application comb (1) is successively supplied with glue from the two supply branches via the branching point (5), such that the working cycle of a glue application can be doubled with unchanged operating frequency of the two directional control valves.
