Method of continously producing multi-part foldable panels

A method of continuously producing multi-foldable panels having a plurality of jointed panel segments (1-3) comprises the steps of continuously forwarding the panel segments (1-3) in a main direction; simultaneously with forwarding the panel segments arranging the panel segments in a flat side-by-side-configuration; and jointing the panel segments by fixing flexible tapes (10) to their small faces (9) extending in the main direction, the panel segments (1-3) being jointed in two areas opposing each other across the panel segments at the same time. Particularly, at least three panel segments are arranged in the flat side-by-side-configuration; and a central segment (2) which is arranged to other panel segments (1-3) in the flat side-by-side configuration of panel segments is either only jointed to one of the two other panel segments (1 or 3) in one of the two areas and to the other of the two other panel segments (3 or 1) in the other of the two areas, or jointed to both of the two other panel segments (1 and 3) in both of the two areas, one of the two joints between the central segment (2) and each of the two other panel segments (1 and 3) being subsequently removed.
