Interruption leads to large amounts of waste and the sp.in process thus making it unprofitable.

It is also known to detect thickening of running threads (Swiss patent 139 1'I 9 J> by using a l'üh I plane .in dJ.IV '' - Lt'CJ! K '"J! TT; \ 'ct "V-'.")'.' O. ^fy VA V ';: 1om In-i ι!. ""("Üiir!

This deflection of the feeler lever is used by a number of devices for actuating a contact and connecting an electrical circuit and thereby requires display devices.

With another monitoring system (DBP 85? 6 ^ 3), Occurring fadon thickening on eccentrically mounted nolls and twisted and thereby a narrowing of a gap up to a predetermined one Width causes the thread to break when eggs The diameter of the pre-cover exceeds this range.

From DT.P 1 -135 ''' ¹ ^ it is known to monitor the spinning process of synthetic threads by a device in which a FiihJer, dvr is designed as an eccentrically mounted rotatable rod, rests on the spinning threads and when a Compression via a contact arm, to which it is elastically connected, closes an electrical circuit and thus triggers a display system.

The advantage of this monitoring device is that it is less Force exerted by the feeler on the thread. Dos device can therefore also for the control of irischgcspoimenen synthetic threads used, ohao di.e quality of these threads by the monitoring device to be a deceitful i.

It was the task of the present binding to develop an arrangement for displaying and registering thickening made of synthetic threads, which allow the number of errors to be recognized and recorded, so that with the number of errors With the help of the voimenen NeOorgebnJ sssg a significantly different sorting of the respective items can be voj'fjcnoinmen, than is possible with the control and monitoring devices known up to now.

The inventive Yux-jj.cliiujig for measuring thickness use / aniations V (J) T. running continuous structures, ijisbesojidei'c of synthetic threads, is characterized by a basic p] ε \ ί. to which a stationary roller, a movable sensor and an electromagnet are arranged, the movable sensor being part of the electromagnet and, with the stationary roller, forming a gap for the continuous thread-like structures. If there is a thickening of the thread in the gap formed by the stationary roller and the movable sensor, the deflection of the sensor changes the magnetic flux of the electromagnet and thus the reversal resistance of the winding of this.

a roller (2) is attached, which can be coated in a ceramic tube ('j). On the same basic principle. te (l) is attached to the axis of rotation (h) of the sensor (5), which carries a ceramic tube (6) at its end, which is connected to the ceramic tube ('}) over a length of tniJ'-gap (7 ·) forms for the thread (8).

To z. B. a spin system for spinning threads made of synthetic high polymers, wj rd the invented gouge device installed below the spinning shaft before winding ohron (' )) uj-.ii (6) is formed. The winding (10) d-.s 1, -1 ek Iromagncten is in series with a resistance ar of a constant voltage. As soon as a thread with a thickening runs between the ceramic stirrers (3) and (6), the sensor (5) is deflected according to the size of this thread thickening, the voltage drop on the winding (OK) becomes smaller. This pulse-shaped voltage change is fed via the lines (11) to an electronic amplifier which amplifies this pulse and, if necessary, lengthens it. An electrical voltage recorder is connected to the output of this amplifier, which deflects according to the height of the pulse and thus proportionally dex · thickness of the spinning fan.
