Abstract
A device for applying adhesive material to card blanks in a packeting machine, comprising a gumming roller and a pressing roller which are substantially mutually tangential and between which the blanks are led in succession to receive traces of adhesive material in predetermined zones. Should the packeting machine halt for a time exceeding a predetermined time limit, detachment means withdraw from the gumming roller that blank disposed between the two rollers in order to prevent it becoming stuck to the gumming roller.
