ABSTRACT OF THE DISCLOSURE Process and apparatus for cutting an elongate complex structure composed of materials having different properties, e.g. a liner and a core which are relatively soft and flexible and susceptible to rupture or crushing and a facing of hard material such as a metal plate. The racing may have an upwardly turned portion, flange portion and groove portion at each side thereof. A carriage and a base frame are movable in the direction of the travel or the complex structure and in the direction perpendicular thereto, respec- tively. Various types of cutters are mounted on the carriage. The complex structure is instantaneously cut in the direction of the width thereof while it is travelling at a high speed. The cut composite structure has smooth and fine cut edges, and is useful for e.g. a siding of a building.
