Abstract: The present invention relates to a scarfing machine, including a base a pair of platens adjustably positioned on the base. The pair of platens are configured as an upper platen and a lower platen such that the upper platen is fixed to the base and the lower platen is adjustably positioned on the base, to receive and support a member for scarfing. Also, at least one platen of the pair of platens is hollow and is defined with an inlet port and an outlet port. The scarfing machine further includes a scarfing tool, extending from either sides and along a length of at least one of the pair of platens, to scarf the member supported between the pair of platens. The scarfing machine also comprises a cooling circuit, fluidly connectable to the inlet port and the outlet port of the at least one platen of the pair of platens. The cooling circuit is configured to supply coolant through the at least one platen to extract heat generated during scarfing of the member.

Abstract: A precured fibrous composite strip (40) for a load-carrying structure, such as a spar cap, for a wind turbine blade (10) is described. The strip has a first longitudinal end (51) and a second longitudinal end (52), a first side (53) and a second side (54) with a width defined as the distance between the first side and the second side, and an upper surface (55) and a lower surface (56) with a thickness defined as the distance between the upper surface and the lower surface. The strip comprises a taper region (60) with a taper length at the first longitudinal end, wherein the taper region tapers in thickness towards the first longitudinal end and comprises: a first taper section (61) proximal to the first longitudinal end and having a first average taper angle, a third taper section (63) distal to the first longitudinal end and having a third average taper angle, and a second taper section (62) between the first taper section and the third taper section and having a second average taper angle, wherein the second average taper angle is larger than both the first average taper angle and the third average taper angle.
