Abstract
A device for applying adhesive to a moving web, comprises a nozzle against which the web is arranged to run and from which adhesive is delivered, and a closure member which is movable between a position in which it allows the web to run against the nozzle and a position in which it moves the web away from the nozzle and lies against the nozzle so as to stop the flow of adhesive from the nozzle.
