Zusammenfassung:	The present invention relates to a method of manufacturing a preform for a wind turbine blade and to a preform mould. The method involves providing a plurality of support elements (70), each support element (70) comprising a planar member (72), arranging a plurality of strips (88) on the top surface (78) of the planar member (72) of each support element (70), wherein the strips (88) are arranged in juxtaposition. Subsequently, a fibre material and a binding agent may be laid on at least part of the strips (88) for forming the preform.
