Embodiment Construction

[0028] exist Figure 7 , a cross-sectional view of a wind turbine blade 1 is shown. On the leading edge 2 of the wind turbine blade 1 a protective shell 3 is mounted to the wind turbine blade 1 , wherein the protective shell 3 is attached to the surface of the wind turbine blade 1 using an adhesive layer 4 . The protective shell 3 is for example made of an elastomeric material and serves to protect the leading edge 2 of the wind turbine blade 1 from erosion occurring during operation of the wind turbine blade 1 . The protective shell 3 may be mounted to the wind turbine blade 1 during manufacture of the wind turbine blade 1 and during repair of an already operated wind turbine blade 1 which has been damaged by erosion during operation.

[0029] exist Figure 8 , a detail of a wind turbine blade 1 is shown. In order to improve the aerodynamic properties of the wind turbine blade 1 after installation of the protective shell 3 it is known to use edge filling for adding additio...

Abstract

Guiding tool for a surface trimming device and trimming arrangement Guiding tool for a surface trimming device (24), comprising a main body (12) with a front side base portion (13) and a backside baseportion (14), which are connected by at least one connection portion (17) of the main body (12), wherein the main body (12) exhibits a recess (15) on a bottom side (16) between the front side base portion (13) and the back- side base portion (14), wherein the main body (12) comprises a fixation means (19) on a top side (18) of the main body (12) opposing the recess (15), wherein a surface trimming de- vice (24) is mountable to the fixation means (19) in such manner that a movable trimming means (28) of the surface trimming device (24) is located in the recess (15) between the front side baseportion (13) and the back side base portion (14).

Description

technical field [0001] The invention relates to a guide tool for surface finishing equipment and a finishing device. Background technique [0002] Wind turbine blades, and especially the leading edges of wind turbine blades, may be subject to erosion during their lifetime. Such erosion may occur in particular when particles such as rain, hail, sand or dust impinge on the wind turbine blades as they rotate at high speeds. Erosion may cause structural damage to the wind turbine blade and reduce the performance of the airfoil of the wind turbine blade. Therefore, it is important to provide a means of repairing and protecting the leading edges of wind turbine blades. [0003] It is known to provide erosion protection casings made of elastomeric materials for erosion protection and for repair of damaged wind turbine blades. These protective shells may be attached to the wind turbine blades by using heat activatable adhesive sheets and heating blankets for curing the heat activ...
