ABSTRACT:
An apparatus for applying glue onto a moving, plane object comprises inlet pipes of the glues a dispenser extending across the path of travel of the object of the dispensing, dispensing nozzles of the glue and means for controllably opening and interrupting the glue flow to the nozzles. The means for interrupting the flow comprise a cylindrical case formed into the frame of the dispenser, extending along the total length thereof, inlet channels for the glue leading to the case, nozzle channels leading out from the case and a pipe element mounted into the case with a sliding fit, said pipe element being equipped with openings for forming a flow connection between the inlet channels of the glue and the nozzle channels in one position of the pipe element with respect to the frame and for closing said flow connection in the second position of the pipe element with respect to the frame.
