<p>The winding device 1 has a rotational axis 3 and two side walls 5, 7 arranged perpendicular to the rotational axis. Each side wall 5, 7 is provided with two slits 9a, 9b; 11a, 11b extending from the middle portion 10, 12 to both extreme ends of the side wall substantially parallel to the edges of the side wall. A supply of bolts 21a, 21b, 21c is arranged to the winding device whereby the bolts have a smaller diameter than the width of the slits 9a, 9b; 11a, 11b and a greater length than the distance between the two side walls 5, 7.</p> |
