Abstract: 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.

Abstract: In order to monitor the adjustment state of the entrainers (1), which are arranged in each case in pairs transverse to the feed direction (4), of a feed chain (2), it is proposed to arrange an adjusting station along the guide of the feed chain (2) and to arrange a measuring station at a spaced interval therefrom. The adjusting station serves to adjust manually the entrainers (1) in a common adjusting plane extending perpendicular to the feed direction (4), whereas the measuring station is arranged to detect the adjustment position of the two entrainers (1) in a measuring plane likewise perpendicular to the feed direction (4) and, in accordance with a tolerance field which can be defined by the user, to generate an error signal which at the same time renders it possible to identify maladjusted entrainers (1).
