Abstract: A method of making a longitudinal reinforcing structure for a wind turbine blade. The method comprises a) providing an elongate master strip (62) of reinforcing material having substantially flat first and second surfaces, the distance between the first and second surfaces defining the thickness of the master strip; and b) dividing the master strip transversely to form a first strip and a shorter master strip, the respective strips being arranged end to end such that a trailing end of the first strip is located adjacent a new leading end of the master strip. The step of dividing the master strip comprises removing material from a dividing region extending through the entire thickness of the master strip, wherein the dividing region is shaped such that a chamfer (19c) at the trailing end (19b) of the first strip is created and a chamfer (63a) at the new leading end (63) of the master strip is created when the master strip is divided.

Abstract translation: 制造用于风力涡轮机叶片的纵向加强结构的方法。 该方法包括：a）提供具有基本上平坦的第一和第二表面的增强材料的细长主带（62），所述第一和第二表面之间的距离限定所述主带的厚度; 以及b）横向分割主带以形成第一条带和较短的母带，相应的条带端对端布置，使得第一条带的后端邻近主条带的新的前端定位。 分割母带的步骤包括从延伸穿过母带的整个厚度的分割区域去除材料，其中分割区域被成形为使得形成在第一条带的后端（19b）处的倒角（19c） 并且当母带被分割时，在主带的新的前端（63）处形成倒角（63a）。
