  • Patent number: 8690744
    Abstract: The invention relates to a method and to an apparatus for producing packs, in particular cigarette packs, from blanks (11, 44), wherein individual regions of a pack blank (11) are adhesively bonded to one another and, if appropriate, to one or more separate blanks (44) by the pack blank (11) being provided with individual portions of glue (28, 29) by means of a valve or a group of valves (26) and blank regions which are to be adhesively bonded together subsequently being held or pressed on one another, wherein the individual portions of glue (28, 29) are applied to the blank regions by means of the glue valve (27) or the group of glue valves (26), and/or wherein a control and/or regulating device (65) automatically controls and/or regulates the size or quantity of the respectively produced portion of glue (28, 29), which size or quantity is produced by the at least one glue valve (27) during an individual valve opening cycle, as a function of at least one parameter.
