ABSTRACT:
A method and apparatus for extracting a fiber sample from a sliver of material for fiber length measurement in which the sliver is successively advanced into and retained by needles in a sample extracting position with the fiber end of the sliver exposed for sampling. The end is then grasped by a clamping member which moves away from the retained sliver to extract the sample. The retention of the sliver is synchronized to follow the advancement of the sliver to its sample extracting position and the movement of the clamping member is synchronized to occur during the retention of the sliver by the needles in this sample extraction position.
