Title: Equalizing device for movements in packing machines, especially machines for making bags and the like

Abstract: A device for equalizing movements in packing machines, especially machines for making bags, which is arranged between a first continuously working withdrawing device for foil-shaped packing material and a second intermittently working second withdrawing device. The device comprises a spring-urged pivotable lever and a stationary support each carrying a plurality of rotatable journalled guiding rollers arranged one behind the other and in spaced relationship to each other. The packing material is looped alternately over one guiding roller on the pivotable lever and a guiding roller on the stationary support and in this manner successively over all guiding rollers in a progressive way, the distance between each two adjacent guiding rollers of the pivotable lever varying in length.
