A process for producing sandwich profiles, in which process, in an even band-like sheet 1, profile depressions 2, which are directed upwards from the plane of the profile, are mutually parallel and are trapezoidal, for example, in terms of their section, are produced by means of a rolling process, between which profile depressions folds 3 are rolled, which run parallel thereto, are directed upwards from the plane of the sandwich profile and are formed of the same metal sheet and in which folds grip buckles 4 are produced. The folds are guided through carriage rollers 7 provided with notches 6 for the folds, in which notches there are pins 8 or the like which are slanted in relation to the direction of travel 5 of the sheet and by which the grip buckles are pressed into the upper edge of the folds. <IMAGE> |
