The device has different parts of its surface coated with different amounts of glue per surface unit or different mixtures of different glue kinds within different parts, with discontinuous transitions. An applicator head is used with a single outlet and two or more inlet channels are connected. To the inlet channels a glue flow is fed discontinuously or continuously so that the flow is either held at a predetermined level or is cut-off. Directly before the applicator head outlet channels the glue, flows are brought together into one single flow. |
