Embodiment Construction

[0051] figure 1 and figure 2 The yarn brake shown in basically consists of the following parts:

[0052] - a tubular brake housing 1 consisting of an upper housing section 2 and a lower housing section 3 releasably connected to the upper housing section 2 ,

[0053] - a rotatably mounted yarn feeding tube 4 coaxially inserted into the upper housing section 2, which engages into (placed in the upper housing section 2) a lock with an outwardly protruding The locking ring 4.1 in the groove 2.1 prevents the yarn feeding bobbin from moving axially,

[0054] - an arm 4.2 arranged or formed on the yarn feeder tube, extending laterally on the yarn feeder tube, on the lower end of which is arranged an inwardly directed projection 4.3;

[0055] - anti-rotation sleeve 5, which has a helical groove or chute (Kulissen) guide 5.1 arranged on the outside, which has a constant or non-constant pitch of the helical path 5.1, the protrusion of the yarn feeding tube 4 4.3 engages into these ...

Abstract

The invention relates to a ball yarn brake for a double twisting spindle, comprising a tubular brake housing consisting of an upper housing section and a lower housing section in threaded connection thereto; a yarn feeding pipe coaxially rotatably mounted in the upper housing section; an upper brake surface ring corresponding to the yarn feeding pipe and the height of which is adjusted by rotating the yarn feeding pipe; a brake ball cooperating with the brake surface ring; a piston guided sealingly in the lower housing section and capable of rotating axially, which piston carries a lower brake surface ring on the outside of its upwardly directed bottom, and which is adjustable downwards in the axial direction by means of suction force against the force of a restoring spring; a holding device arranged between the two brake surface rings for the brake ball; a braking force adjusting device acting on a brake unit consisting of the two brake surface rings and the brake ball, and characterized in that the holding device for the brake ball is mounted on the lower end of a sleeve carrying the upper brake surface ring.

Description

technical field [0001] The invention relates to a spherical yarn brake. Background technique [0002] In a two-for-one twisting machine, a certain yarn tension must be applied to the twisted yarn before it enters the rotating spindle. The yarn tension must be chosen appropriately so that a stable twisting process is guaranteed over the entire operating time of the package. The criterion for the required yarn tension is that the package must not fall below the minimum yarn storage volume during the entire operation on the twisting spindle storage disc so that the balloon remains in a stable shape. If the yarn storage is below this value, the balloon will already have a tendency to temporarily collapse when there are minor disturbances (mass fluctuations in the balloon, hooks on the yarn supply bobbins). Inadvertent contact of the balloon with the edge of the spindle pot will occur, which may cause damage to the yarn up to yarn breakage. In addition, if it is a plied raw ya...
