Method and an apparatus for forming profile elements

A method for forming profile elements from a multilayer stack of pre-impregnated fibers, the method comprising:

• moving the multilayer stack in a feed direction at a feed speed by a first set of conveyor belts and a second set of conveyor belts, wherein the first set of conveyor belts engage with an upper surface and a lower surface of a first lateral edge section of the multilayer stack, wherein the second set of conveyor belts engage with an upper surface and a lower surface of a second lateral edge section of the multilayer stack, wherein the second lateral edge section is opposite to the first lateral edge section, wherein the first and second sets of conveyor belts hold the first and second lateral edge sections in a starting plane, and wherein the first and second sets of conveyor belts are arranged so that a distance between the first and second sets of conveyor belts decreases in the feed direction;
• and
• moving a middle portion of the multilayer stack over a ramp upwardly inclined in the feed direction with respect to the starting plane.
