A packaging apparatus for small piece goods, the use of the packaging apparatus, and a method for producing a blister tube are provided. The packaging apparatus includes a packaging material guiding device for providing a shaped packaging material web suitable for receiving small piece goods, a longitudinal joining device which is arranged downstream of the packaging material guiding device and a transverse joining device which is arranged downstream of the packaging material guiding device. The transverse joining device joins the shaped packaging material web together at predetermined intervals transversely to the direction of travel to form a transverse joining area. The transverse joining device includes two joiners, a first joiner having a plurality of embossers that are individually movable transversely to the direction of travel and are arranged so that they can be extended from the first joiner and retracted into the first joiner.

An assembly for producing sealed packaging units (14) from a sheet packaging material, comprises: an advancement device (21) for advancing the sheet packaging material along an advancement direction (F), a longitudinal sealing device for sealing opposite borders of the sheet packaging material along a longitudinal sealing band arranged parallelly to the advancement direction (F), thereby forming a continuous tube (15), a transverse sealing device (29) for sealing the continuous tube (15) transversely to the advancement direction (F), so as to define a sealed packaging unit (14). The transverse sealing device (29) comprises a sealing element (30) and an abutment element (31) that are intended to mutually cooperate during sealing while being located on opposite sides of the continuous tube (15). The sealing element (30) is so configured as to act on a side (27) of the continuous tube (15) on which the longitudinal sealing band is provided.
