Set forth other advantage and the feature according to the design of warp thread faciola monitor of the present invention below.
In a kind of improvement project of warp thread faciola monitor, the direction that the channels configuration for warp thread faciola in senser element becomes to move back and forth between resting position and operating position transverse to senser element.Provide thus warp thread faciola through the very short of senser element and the very little path that therefore rubs.In addition prevent and favour moving direction and be applied to the deflecting force on senser element.Finally, in this design, the variation of the tension of warp thread faciola and serious sag more or less related to this cause the remarkable displacement of senser element, and it certainly can more easily be detected in the case of very little displacement.
Advantageously, the channels configuration for warp thread faciola in senser element is the notch along lateral open, obtains thus very large time saving in the time of circular loom entry into service in the time hanging into warp thread faciola.
In order to ensure the clamping force of the restriction between clamping device and senser element, if senser element anti-torsion ground supports, this is favourable.
If clamping device is equipped with the clamping area that is configured to rubbing surface in warp thread faciola monitor according to the present invention, can realize the very high clamping force being applied on warp thread faciola, wherein, rubbing surface is preferably for example, by friction lining (Reibbelag) (rubberised layer, Gummierung) realize, or realize by rough surface portion or structure toothed region.
In order to ensure warp thread faciola is clamped between clamping device and senser element, in a kind of flexible program of the present invention, be arranged to the surface towards clamping area of clamping area and/or senser element to become towards each other with the configurations of convex.
As other measure of the pinch effect for generation of very high, can be arranged to clamping device in the plane of the direction that moves back and forth transverse to senser element at least at some section around senser element.Even can obtain reliable pinch effect in the case of the faciola position changing by this measure.
