<p>A bobbin 1 has an adjusting bearing 27 which is incorporated in the bobbin shank 2 and which has a permanently fixed setting sleeve 28 with a conical receiving bore 31, in which a bearing sleeve 29 is mounted by means of a corresponding conical outer circumferential surface. The bearing sleeve 29 has a continuous longitudinal slot 35 and is screwed together with the setting sleeve 28, so that a rotation of the bearing sleeve 29 leads to a corresponding change in the diameter of its bearing bore 33. The particular setting made is secured by means of a locking screw 40. <IMAGE></p> |
