Embodiment Construction

[0029] exist figure 1 A longitudinal view of the spindle top 1 of the spinning or twisting spindle 2 is shown in . In its lower part, the upper spindle part 1 merges into a conical bearing surface 3, on which a drive spindle disk (not shown) and a spindle shaft are connected in a known manner. In the upper region of the spindle upper part 1, a bobbin coupling 4 is arranged, which will be described in detail below.

[0030] A bobbin 5 , which is shown in longitudinal section, is inserted onto the spindle upper part 1 . Its underside rests on the conical bearing surface 3 or rests against a stop and is thus centered on its underside. The bobbin 5 is synchronously driven along the direction of rotation by the rotating spindle upper part 1 during the operation of the spindle 2 .

[0031] When inserting the bobbin 5 into the spindle upper part 1, usually the last 50 mm of the bobbin 5 is exposed downward. This is possible both with manual and automatic doffing. Alternatively, ...

Abstract

Longitudinal recesses near the top (1) of the spindle (2) accommodate projections on the interior of the yarn tube to provide the drive coupling. The sides of the recesses are tapered and shaped to guide the projections as the tube is placed on the spindle and can have a re-entrant region to hold the projection. The number of recesses on the spindle is a multiple of the number of projections on the yarn tube. Also claimed are yarn tubes and spindles fitted with a drive coupling of this kind. The spindle recesses can be situated in a separate component attached to the top of the spindle. The recesses can have a base shaped as a concave curve.

Description

technical field [0001] The invention relates to a bobbin coupling for spinning or twisting spindles, wherein the synchronous driving of the bobbin on the upper part of the spindle is realized by a form connection comprising dimples and protrusions. Background technique [0002] It is known that the bobbins are centered and simultaneously driven synchronously by elastic elements. It is also known that the centering and synchronizing of the bobbin tubes takes place under the action of centrifugal force via coupling elements. In both variants, either a non-positive connection or a form-fit connection of the tube coupling can be produced, and optionally also a non-positive connection and a positive connection at the same time. However, it has the disadvantage that such a bobbin coupling requires additional components which can be lost during spindle operation and, besides, is of a particularly complex construction. [0003] A form-fitting tube coupling of the type mentioned at...
