Abstract

A supporting core for using in a device for forming plates into a structured hollow profile and a method for producing structured hollow profiles from a plate, which on the one hand ensures an all-over support of the plate, and still enables the production of hollow profiles with a variable cross-section or a curved course, is provided by including individual supporting members, which when pushed together at least in part form as a surface an inner contour of the hollow profile to be produced and are interconnected by means of coupling elements, wherein the coupling elements allow the supporting members to be pulled-apart, and wherein the supporting members are interconnected in a hinged manner in the pulled-apart position.
