Abstract
A composite blade, in which there is an essentially plate-like blade component with a composite-construction and retention members arranged in its rear part is intended to be installed in a special blade holder with the retention members remaining in the throat of the blade holder. The retention members are formed of a profiling arranged as a lateral extension of the blade component. The profiling extends essentially over the entire length of the blade and is of the same piece as the blade component.

A composite blade, in which there is an essentially plate-like blade component with a composite-construction and retention members arranged in its rear part, and which blade is intended to be installed in a special blade holder with the said retention members remaining in the throat of the blade holder, characterized in that the retention members are formed of profiling arranged as a lateral extension of the blade component, which profiling extends essentially over the entire length of the blade and which is of the same piece as the blade component.
A method for manufacturing a composite blade, in which method an essentially plate-like blade component is formed from composite material, and retention members are arranged in the rear part of the blade component to retain the blade in the throat of a special blade holder, characterized in that a unified blank is formed from composite material, to that both the blade component and the profiling forming the retention members are manufactured simultaneously, and from which blank the blade with its retention members is detached.
