Method and tool for manufacturing of build up products

A method of producing from sheet material a composite object comprising the steps:

• feeding a first sheet material stepwise in a first feeding direction of a first material path of a first feeding length through a tool from a first infeed section to a discharge section, the first feeding direction being defined by two first sheet material path guides mounted on a plate, the first sheet material being, at least between certain feeding steps, processed at one or more first sheet material processing stations,
• feeding at least a second sheet material through a second feeding section stepwise into the tool in a second feeding direction of a second material path of a second feeding length, the second feeding direction being defined by two second sheet material path guides mounted on the plate, the second sheet material, at least between certain feeding steps, being processed into wholly or partly finished second component parts of the object at one or more second sheet material processing stations, the first and second feeding directions being different, and
• joining the second component parts in the tool together with the first component parts of the object, wholly or partly finished from the first sheet material, and causing the joined first and second components to leave the tool in the assembled state in the first feeding direction.
