摘要

PROBLEM TO BE SOLVED: To provide a focusing device capable of producing a uniform yarn, and a draft device for the focusing device. The present invention is a focusing device and a drafting device for a focusing device, wherein the focusing device is for a drafting machine for a spinning machine, particularly a ring spinning machine, for focusing the drafted sliver. The present invention relates to a focusing device, which is a focusing device and is provided with a focusing zone in which a suction flow is generated perpendicular to the fiber transport direction by using the suction opening 4. In order to provide a focusing device and a draft device for the focusing device, which enables the production of uniform yarn, the focusing device is provided with a focusing element provided with a guide roller, and the guide roller is guided by a sliver. It can be rotatably placed facing the suction opening 4 in the region of the focusing zone so as to engage the rollers. [Selection diagram] Fig. 1
