Abstract

The invention relates to a device for processing at least one packaging container, in particular for stretching out at least one stretching element of the packaging container, comprising at least one pivoting-arm pair, which comprises a first pivoting arm and a second pivoting arm, which is arranged in a mirror-symmetric manner in relation to the first pivoting arm with respect to an axis of symmetry perpendicular to the at least one linear axis, wherein the first pivoting arm is supported in such a way that the first pivoting arm can be rotated about a first pivoting-arm axis of rotation perpendicular to the axis of symmetry in a first rotational motion and can be displaced in the direction of the at least one linear axis in a first displacement motion and the second pivoting arm is supported in such a way that the second pivoting arm can be rotated about a second pivoting-arm axis of rotation perpendicular to the axis of symmetry in a second rotational motion and can be displaced in the direction of the at least one linear axis in a second displacement motion, and comprising a coupling transmission, which is designed to produce the first rotational motion and the first displacement motion of the first pivoting arm and the second rotational motion and the second displacement motion of the second pivoting arm from at least one first driving motion and one second driving motion, and wherein the first rotational motion and the second rotational motion are synchronous to each other and in opposite directions and the first displacement motion and the second displacement motion are synchronous to each other and in opposite directions.
