ABSTRACT:
In the manufacture of certain types of packets, rotary folding units (10) are used which have along their perimeter a plurality of hollow folding mandrels (14) projecting at one side. On these mandrels, blanks, namely inner blank (10) and pouch blank (11) are folded in succession. Holding bands (34, 59) serve to position the blanks exactly on the folding mandrels (14), said bands extending outside the movement region of the folding mandrels (14) and lying with a holding bight (35) against the side of the folding mandrels (14), or the blanks, lying radially on the outside, fixing same as they do so.
