Binding element which mainly comprises a U-shaped profile (2) made of a heat-conducting material, which U-shaped profile (2) consists of a back side (3) and two side walls (4), on which back side (3) is provided a layer of glue (8) which melts under the influence of heat, characterised in that the distance between the side walls (4) at a distance from the back side (8) is smaller than the width (A) of the inside of the back side (3) which actively glues the leaves together. |
