Abstract: A turning device, for manufacturing wind turbine blades and turning moulds relative to each other, having a base, a rotational part movable relative to the base on an rotational axis, a first linear actuator with first and second ends, the first end attaching to the base, and the second end attaching to the rotational part at a first anchor point on a first turning axis, and a second linear actuator having first and second ends, the first end attaching to the base, and the second end attaching to the rotational part at a second anchor point on a second turning axis. The first turning axis is a first distance from the rotation axis and is moved on a first arc on the rotation axis, and the second turning axis is a second, different distance from the rotation axis and is moved along a second arc on the rotation axis.
