Abstract
In a fiber opening device in open-end spinning unit, having a combing roller which is encased by a casing and forming a fiber transferring passage between said combing roller and said casing, a wear-resistant member, preferably a member having a pin shape, is provided at an edge of an opening, e.g. a trash exit port opening formed in said casing and communicated with said passage. The structure of the fiber opening device according to the present invention makes possible easy installation of the wear-resistant member, and prevents harmful wear or bruising at said edge portion of the opening in the casing.
