Brush Patents (Class 493/284)
  • Patent number: 4838846
    Abstract: In the production of cigarette packs, especially soft-cup packs 11, folding tabs have to be provided with glue marks 15. To make accurate glue marks 15 even on packaging machines operating at a high working speed, a glue unit 16 is arranged on the periphery of the folding turret 35 in such a way that glue faces 32 of the glue-coating member 21 having glue wings 22, 23 come up against a side-wall tab 13 to be provided with glue marks 15, this at the same time being deformed elastically. As result of the relative movement, the glue wing 22, 23 is rolled on the side-wall tab 13 by means of the glue face 32, thus producing an accurate glue pattern.
