Abstract (en)
[origin: WO0136176A1] The invention relates to a method and arrangement for manufacturing an elongated grooved element, in which method the grooved element is manufactured by extruding plastic material onto a base element and by forming open grooves (2) on the surface of the plastic material along the length of the grooved element. To reduce defects in forms, the grooved element is manufactured in two stages (3, 4): in a first stage, a pre-grooved support structure is formed and, in a second stage, the actual grooved surface is formed onto the pre-grooved support structure.
