Holding element for a device for monitoring the quality on a mechanical weaving loom

Abstract

The invention relates to a device for optically monitoring a woven web of endless fabric on a mechanical weaving loom or a winding device. The monitoring device includes a holding element and extends over the entire width of the woven web of endless fabric. The monitoring device is directly in contact with the woven web of endless fabric and is held indirectly on the mechanical weaving loom, in the region between a delivering roller and the winding of the web of endless fabric onto a cloth beam or a large roller parallel to the delivery roller. The holding element has an axle located on the monitoring device and an axle located on the mechanical weaving loom, the two axles extending parallel to each other and being interconnected by a pivoting arm.

1 . A mounting for a device for the optical monitoring of a woven material web on a loom, including a mounting, in which the monitoring device extends over the entire width of the woven material web, in which the monitoring device is mounted, indirectly connected to the loom, in contact with the woven material web in the region between a take-off roller and the point at which the material web is wound onto a loom beam or onto a large-scale winding roller and parallel thereto, wherein this mounting comprises an axis on the monitoring device and an axis on the loom, and the two axes extend parallel to one another and are connected to one another by way of a pivotal arm.  
   
   
       2 . A mounting according to  claim 1 , wherein the mounting on the axis connected to the loom is performed by means of a sleeve formed by two half-shells, with the pivotal arm secured to one half-shell.  
   
   
       3 . A mounting according to  claim 2 , wherein the pivotal arm is connected in one piece with one of the two half shells.  
   
   
       4 . A mounting according to  claim 2 , wherein to each side of the monitoring device there is arranged a bearing pin, with the bearing pins lying in a straight line and forming the axis ( 7 ) of the monitoring device.  
   
   
       5 . A mounting according to  claim 1 , wherein a bearing housing is integrally formed with the pivotal arm and the bearing pins of the monitoring device are mounted pivotally in this bearing housing, and wherein a pin extending parallel to the bearing pin is borne such that it may be clamped and pivoted in an arcuate slot for the angular positioning of the monitoring device.  
   
   
       6 . A mounting according to  claim 1 , wherein the pivotal arm is in the form of a rod which is provided at both ends with a clampable bearing capable of angular adjustment.  
   
   
       7 . A mounting according to  claim 1 , wherein it holds the monitoring device such that it may pivot about both axes to lie against the material web in the region in the vicinity of an expanding roller or a deflection roller of the loom.  
   
   
       8 . A device according to  claim 7 , wherein the mounting holds the monitoring device such that it may pivot about both axes to lie against the material web in the region directly upstream, in relation to the direction of transport of the textile material web, of the expanding or deflection roller.  
   
   
       9 . A device according to  claim 7 , wherein the mounting holds the monitoring device such that it may pivot about both axes, to lie against the material web in the region directly downstream, in relation to the direction of transport of the textile material web, of the expanding or deflection roller.
