A spool for winding up an adhesive carrier tape of a packaging taped imbricated bag chain in an apparatus for taking up a succession of imbricated packaging bags including a core with a core surface and walls forming a race where turns of tape are wound up, wherein the core surface includes resilient means for releasing a radial pressure acting on the turns of tape that have been wound up first. Also, a spool assembly for winding up at least two adhesive carrier tapes of a packaging taped imbricated bag chain in an apparatus for taking up a succession of imbricated packaging bags includes at least two spools, each spool having a core surface and walls forming a race where turns of tape are wound up, wherein the core surface includes resilient means for releasing a radial pressure acting on the turns of tape that have been wound up first. |
