Abstract
Abstract In spreading glue onto blanks for the manufacture of packs, it is necessary to ensure that the metered amounts of glue spread onto the glue spots are neither too large nor too small. There is therefore a need to provide a glue transfer which is precise in respect of amount of glue, glue pattern and relative positioning. For this purpose, glueing rolls, glueing rollers and glueing segments are used, which in the region of the glue transfer are provided with shallow depressions or recesses, which accommodate limited amounts of glue for transfer onto the blank.
