Abstract
A description is given of an apparatus for folding in the front face of a pack (1, 1') made of cardboard coated with plastics material, the front face of which pack is quadrangular in the plan view in the folded in condition and has a transverse sealing seam (5) which can be folded over, having a fold member (b) and a companion fold member (a), which are both driven movably along specific paths of movement by at least one lever mechanism (8-13), and amongst which a conveyer is arranged at a spacing away in the Y-extent, which conveyer moves the packs (1, 1') in the X-extent, wherein the Y-axis is vertical to the X-axis and the zero point of the axes (X, Y) is disposed in the end fold position of the two fold members (a, b) so that the bottom of a pack can be folded in one single step without any subdivision into pre-folding and re-folding steps, and so that no component parts of the machine engage in the pack, preferably not even over the open pack, it is provided that a Y-Z-plane extending in the Z-extent is disposed in the Y-axis and is intersected vertically by the X-axis, that the paths of movement of both fold members (a, b) extend symmetrically to each other relative to the Y…
