Abstract: A valve for processing glue or other media, the valve having magnets, in particular permanent magnets, that are used for actuating a closure member (16). Two individual magnets (22, 23) located opposite one another are provided, at least in a region which is in contact with the medium or glue, with a protective layer or covering (34), which is preferably designed as a cap and consists of titanium, other metal or plastics material, in order to protect the magnets (22, 23) against the effects of the medium.

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.
