Process and apparatus for cutting an elongate complex structure

A process for cutting a complex structure composed of a facing of hard material, a core of foamed material and a liner of flexible material, which is characterized in that:

• when the length of the complex structure continuously issued from a complex structure-forming apparatus approaches close to a predetermined length, a pair of first upper cutters (23) arranged in parallel to each other in the direction of the width of the complex structure and a second upper cutter (24) arranged between the pair of the first upper cutters (23), are moved in the direction of the travel of the complex structure;
• when the length of the complex structure reaches the predetermined length, while moving the first and second upper cutters (23) and (24) at the same speed as the travelling speed of the complex structure, the liner and the core are cut by the first upper cutters (23), then the second upper cutter (24) is advanced between the pair of the first upper cutters (23) to cut the facing and thereafter the first and second upper cutters (23) and (24) are retracted from the respective cutting positions;
• and
• the movement of the first and second upper cutters (23) and (24) is stopped and they are then returned to their initial positions.
