Abstract
A method for producing a plait-like portion on a tubular packaging casing which accommodates a filling material, wherein the plait-like portion is at least approximately free of filling material and comprises a longitudinal plait-axis, including the steps: constricting a filled tubular packaging casing by moving a first pair of displacer elements of a first displacer unit and a second pair of displacer elements of a second displacer unit from an opened into a closed position by use of a first drive unit, creating a displacer clearance between the first and second pair of displacer elements, producing a plait-like portion by moving the second displacer unit parallel to the longitudinal plait-axis away from a narrow position in which the second displacer unit is adjacent to the first displacer unit, into a spread position in which the second displacer unit is away from the first displacer unit.
