Arrangement for producing embossed cushioning material and method for producing embossed cushioning material

An arrangement for producing embossed cushioning material from an initially flat material, comprising an embossing device for providing a plurality of embossed protrusions to the material, an undulating device comprising undulated forming spaces which creates undulations in the initially flat material prior to the undulated material being provided to the embossing device, and a conveying means for conveying the initially flat material along a transport path in a continuous process through the undulated forming spaces, wherein the undulating device, seen in the direction of the transport path, comprises at least two stages each comprising an undulated forming space, the undulated forming space of a downstream stage differing in number and/or height of undulations from the undulated forming space of an upstream stage, wherein each stage comprises, seen in lateral direction, at least one region which is free of any undulated forming space and which is delimited on both sides by regions having an undulated forming space.
