1. A packaging machine for producing a packaging unit from a packaging sleeve group comprising a plurality of flat folded, upright, packaging sleeves, and an outer packaging, the packaging machine comprising at least one conveyer unit for conveying the packaging sleeve group, at least one outer packaging unit for preparing an outer packaging-shaping sheet material in a base position, a sealing unit for sealing of the outer packaging-shaping sheet material enclosed in the packaging sleeve group, and holding plates for laterally pressing together the packaging sleeve group, the holding plates each being moveably suspended on a rail in a direction of transport of the conveyer unit,
wherein, in the base position, the sheet material is stretched across the conveyer unit such that the sheet material is stretched above and below the conveyer unit and the sealing unit is positioned downstream of the outer packaging-shaping sheet material in the direction of transport of the conveyer unit,
wherein the at least one conveyor unit conveys the packaging sleeve group in the direction of transport,
at least one sheet material brake for securing the outer packaging-shaping sheet material arranged, at least in the base position, upstream of the sealing unit in the direction of transport, and
a heat treatment unit downstream of the at least one outer packaging unit to apply protruding sheet material to downstream sides of the packaging sleeve group.
