Process for producing a polymer leading edge protection sheet with chamfered side edges

A polymer leading edge protection sheet comprising a polymer leading edge protection sheet, wherein the polymer leading edge protection sheet is formed by a comprising:

• providing a polymer material sheet comprising a first major surface and a second major surface, each of the first major surface and the second major surface comprising a width extending in a width direction between side edges of the polymer material sheet, wherein the first major surface and the second major surface surfaces are oppositely directed, wherein the polymer material sheet comprises a thickness;
• shaping the polymer material sheet into a polymer leading edge protection sheet by providing the polymer material sheet between at least one pair of rollers comprising a first roller and a second roller, wherein:
• the first roller comprises a first shaping surface extending between opposing ends of the first roller, wherein the first shaping surface extends concavely between said opposing ends;
• the second roller comprises a second shaping surface extending between opposing ends of the second roller;
• the first shaping surface and the second shaping surface are arranged opposite each other;
• the thickness of the polymer material sheet is altered by the first shaping surface and the second shaping surface of the first roller and the second roller, respectively, during rotation of the first roller and the second roller to obtain the polymer leading edge protection sheet with chamfered side edges, the polymer leading edge protection sheet having a reduced thickness at the chamfered side edges when compared to a sheet thickness at a center area.

A wind turbine blade system comprising:

• a wind turbine blade;
• and
• a polymer leading edge protection sheet applied to the wind turbine blade wherein the polymer leading edge protection sheet comprises a polymer leading edge protection sheet, wherein the polymer leading edge protection sheet is formed by a process comprising:
• providing a polymer material sheet comprising a first major surface and a second major surface, each of the first major surface and the second major surface comprising a width extending in a width direction between side edges of the polymer material sheet, wherein the first major surface and the second major surface surfaces are oppositely directed, wherein the polymer material sheet comprises a thickness;
• shaping the polymer material sheet into a polymer leading edge protection sheet by providing the polymer material sheet between at least one pair of rollers comprising a first roller and a second roller, wherein:
• the first roller comprises a first shaping surface extending between opposing ends of the first roller, wherein the first shaping surface extends concavely between said opposing ends;
• the second roller comprises a second shaping surface extending between opposing ends of the second roller;
• the first shaping surface and the second shaping surface are arranged opposite each other;
• the thickness of the polymer material sheet is altered by the first shaping surface and the second shaping surface of the first roller and the second roller, respectively, during rotation of the first roller and the second roller to obtain the polymer leading edge protection sheet with chamfered side edges, the polymer leading edge protection sheet having a reduced thickness at the chamfered side edges when compared to a sheet thickness at a center area.
