ABSTRACT:
A combing roller for an open-end spinning machine which utilizes whirling airflow. The roller has on its circumferential surface and in its axial direction dovetail grooves, in which needle plate laminated members which have needle rows in the axial direction of the roller are removably mounted so that each needle row can be mounted and removed simply. The needle plate laminated member is made by connecting together in a row a plurality of needle plates, with a spacer between adjoining ones in some cases, by a connecting member. The needle plate has at its upper part a needle base portion with at least one needle head and at its lower part a needle insertion portion with a dovetail shape to be fitted in a dovetail groove with the roller, having at the substantially central part of its bottom a part in which the connecting member is inserted and fastened.
