Definitions

  • the invention relates to a device for monitoring the formation of a roll on a sliver or sliver-guiding roll in a spinning machine with a pressing means for pressing the roll against a second roll or an analog moving, sliver-guiding element.
  • Such a device is known, for example, from European Patent Publication No. 0062185.
