Definitions

  • the invention relates to a pair of rollers Preamble of claim 1 corresponding type.
  • roller pairs come e.g. in plants for continuous Equipment of textile webs before, be it as Squeeze rollers, be it as rollers for determining the forward speed the web.
  • Speeds of the pair of rollers and the downstream Aggregate can form at the outlet of the roller pair a loop in the web.
  • the web section is usually damp and has one sufficiently large loop the tendency to attach to the lower one Put on the roller of the roller pair. That can cause that the relevant web section the entire lower Rounded roller and together with that in the pair of rollers incoming web into the nip.
  • the fix of such a so-called merchandiser requires that Shutdown of the entire system and is accordingly expensive and undesirable.
  • the invention has for its object a pair of rollers of the type described so that such goods winder be avoided.
  • the sensor gives when the web is too far around the lower roller has wrapped around a signal, which used to control the system in the form can that the further wrapping around the relevant web section around the lower roller is prevented. It is avoided by the loop becoming so large that its leading end, carried by the lower roller is drawn into the roll gap.
  • one of these possibilities is immediately stop the rotating rollers of the pair of rollers. In general, this will not happen suddenly can, but are the speeds at which e.g. a textile web is running in a continuous line, not very high, so a shutdown anyway can happen fairly quickly and so early that the Crest fold of the web wrapping around the lower roller has not yet reached the roll gap. This is natural also a question of the positioning of the sensor.
  • the alternative according to claim 3 uses the signal from the sensor not to completely stop the rollers and thus the entire system, but ensures control of the Speed such that the impending roll winder is extractable, i.e. that the loop formed is reduced becomes.
  • a mechanical includes displaceable button that operates a switch. So when the web apex comes to the button this is pushed aside and thereby actuates the Counter.
  • a textile fabric web 10 that is damp can is via two support rollers arranged at the same height 1.2 headed. Between the idlers 1,2 Roller pair 3 with an upper roller 4 and a lower roller 5 arranged, which form a roll gap 6 between them, through which the web 10 is passed.
  • the web 10 takes in horizontal lines in the drawing Course 10 'between the support roller 1 and the Roll gap 6.
  • Sensor provided in the immediate vicinity of the Surface of the roller 5 comprises a mechanical button 9, which is pivoted and pushed a little aside or is pivoted when the apex reaches it.
  • a switch is actuated by the pivoting.
  • the corresponding signal is sent via line 15 a control unit 12 which is supplied via the lines 19,14 is connected to the drives of the rollers 4,5 and it stops when the signal occurs.
