ABSTRACT:
At a station (1) in a packaging line for folding a flap (2) of a bag (3) along a shaping line (10) of the flap (2) and for compressing the folded flap (2) by a folding element (5) against a resistance member (4), the folding element (5) is driven by a drive mechanism (16) into two directions (8, 9). The two directions are perpendicular to one another. A holding element (11) is provided which can be moved against the shaping line (10) and has a rectilinear shaping edge (12). The rectilinear shaping edge (12) guarantees a straight, position-exact shaping line (10). The folding element (5) causes the folding and compressing, and can be returned into a start position for the next flap (2).
