  • the first and second material run preferably do not cross in the first mode of operation.
  • a crossing of the third and fourth material run is to be understood as meaning that the flat material located in the material run or a part thereof crosses, in particular at a distance from one another.
  • the first strand-shaping device is assigned a first pivotable guide device, which guides the flat material in the first mode of operation in the first material run and in the second mode of operation in the third material run, with a change in a pivoting angle of the guide device causing a rotation of the means of the first strand-shaping device formed strand causes about its longitudinal axis, a very efficient guidance of the sheet material in the first run of material and the third run of material is possible.
