There are known thread cleaners in which the setting
is carried out by moving the knife directly,
whereby to determine the specified distance a tongue

place between the thread guide pin and the knife edge is inserted. The disadvantage here is that the setting is essentially dependent on the feeling of the person making the setting and by exerting more or less great pressure on the tongue gauge, relatively large setting deviations are accepted must be taken. Another disadvantage is that the settings and any follow-up controls only occur when the machine is at a standstill the winding unit -nd removed thread can be made and further adjustment changes not easily are recognizable.

The present innovation aims to avoid the disadvantages of the known embodiments and to create a thread cleaner which can be set, checked and readjusted easily and without the aid of a gauge and without having to stop the winding unit. This is achieved in that the knife attacking adjusting means is a transverse to the knife bar in the case body _'t

With these measures it is now possible without intervention in the gap between the thread guide pin and the knife edge penetrated by the thread to be cleaned, the gap width precisely set by the setting is now made on the basis of markings on the adjustment means, which thanks to the reduction between the adjustment means and the knife with a thus large adjustment range of the adjustment means

and a comparatively very small displacement path of the knife, a very fine displacement of the knife and thus allow the finest adjustment of the gap width.

An example embodiment of the subject matter of The innovation is shown below with reference to the drawing, which shows a thread cleaner in perspective removed housing cover, illustrated, explained in more detail.

According to the illustration, the thread cleaner comprises a housing body 1 which is suitable for fastening in the correct position in the area of a winding unit on a winding machine, not shown in detail. From this housing body 1 protrudes from a molded carrier 2 on which a self-supporting thread guide pin 3, which extends parallel to a longitudinal edge of the housing body and is made of wear-resistant material, is arranged. The cutting edge of a knife 4, which is firmly connected to the free end of a guide rail 5, extends parallel to the thread guide pin. This rail 5 is guided in corresponding sliding grooves 6 in the housing ¹ ″ body 1 in such a way that the knife 4 extends through longitudinal.

lets move away from this. The distance d between the cutting edge of the knife 4 and the thread guide pin 3 is here, in a known manner, a measure of the degree of cleaning that passes between the knife and the thread guide pin Thread with a given thread number. To lock the Knife 4 in the set relative position to the thread guide pin 3, a locking screw 7 is used, which has a corresponding longitudinal slot 8 in the guide rail penetrates and which is threaded into the housing body 1.

An adjusting slide 9 is used to adjust the knife 4 together with the guide rail 5 relative to the thread guide pin 3, which extends approximately in the middle of the guide rail 5 directly above this and at right angles to this and which is also guided in corresponding sliding grooves 10 in the housing body 1. An unspecified one The cover plate that can be screwed onto the housing body 1 completes the guide means for the knife rail 5 and the adjusting slide 9.

Approximately in the middle of the adjusting slide 9 at its intersection with the rail 5, the adjusting slide 9 has a Constriction in such a way that two inclined, parallel control edges 11 are formed which are free of play are guided between two control pins 12 on the top of the knife bar 5. As shown here from the illustration readily apparent, a displacement of the adjusting slide 9 now causes a transverse movement of the knife bar 5 and the like thus an adjustment of the gap width d between knife 4 and thread guide pin 3. As can also be seen without further ado, forms the size of the angle of the control edges 11 with the longitudinal axis of the Steiischieber 3 a measure for the Ueber ^, setting ratio between the travel of the adjusting slide '9 and the displacement of the knife rail 5. The smaller This angle is, the greater the required travel on the adjusting slide 9 for a displacement unit the knife slide 5. Correspondingly, a linear one, cooperating with a mark 13 on the housing body 1 and on the adjusting slide top applied scale 14 is calibrated, according to which now the setting of the thread guide he follows. To facilitate handling when setting

of the thread guide is one end of the adjusting slide 9 ad.t. a permanent pressure plate 15 provided on the adjusting slide its full length is pretensioned by a spring 16.

In the case of an embodiment that deviates from the above the adjusting slide can also be arranged displaceably at an angle to the knife rail. As adjustment means are also spindle drives or rack and pinion drives or the like. conceivable.

Claims (4)

-δ- protection claims 1. Thread cleaner for winding machines, with a thread guide pin and one adjustable and lockable with respect to its distance from the thread guide pin Knife, whereby the adjustable distance between the thread guide pin and the knife is a measure of the thread number and the degree of cleaning of the thread to be monitored, and wherein the knife is in a housing body is guided displaceably and lockable, characterized in that acting on the knife Adjusting means an adjusting slide which is guided transversely to the knife rail (5) in the housing body (1) <9), which is in contact with at least one control edge (11) with a control pin (12) on the knife rail (5), the adjusting slide (9) being at right angles extends to the knife rail (5) and the control edge (11) on the adjusting slide (9) with the adjusting slide longitudinal axis Includes angle, the size of which is a measure of the transmission ratio represents between the travel of the adjusting slide (9) and the displacement of the knife (4). 2. Thread cleaner according to claim 1, characterized in that the adjusting slide comprises two parallel control edges, which are guided without play between two control pins on the knife rail. 3.
