  • the assembly comprises a pair of rotatable cooperating roller discs forming a groove therebe- [30] Foreign Applicatiun Priority Data tween for receiving yarn therearound to frictionally June 12, 1971 Germany P 2
  • This invention relates to a cleaning roller assembly for textile yarn which is adapted to be positioned tangentially in the path of yarn traveling through a textile yarn processing machine, such as a twister, spinning frame or the like, for cleaning dust and other undesirable particles from the yarn; and more specifically to such a cleaning roller assembly which eliminates undesirable accumulations of dust and other particles which might cause clogging and prevent free rotation of the roller assembly.
  • yarn being processed thereon often contains undesirable dust, dirt, lint and other undesirable foreign particles which hinder the yarn processing operation and lower the quality of the processed yarn.
  • Various devices have been previously proposed for cleaning the yarn during yarn processing op.- erations in yarn processing machines. These prior devices have included baffle pins inserted in the path of yarn by which the yarn is imparted multiple changes in direction and thereby subjected to a frictional scraping action for cleaning of the yarn.
  • rollers have been proposed around which the yarn is looped and which frictionally cleans the yarn as it passes therearound.
  • a cleaning roller assembly which creates an air suction stream which flows around a yarn receiving and cleaning groove formed by a pair of rotatable cooperating roller discs and which flows from such groove coaxially with the axis of rotation of the roller discs.
  • a cleaning roller assembly comprising a pair of freely rotatably mounted, cooperating roller disc means having opposed faces forming a groove therebetween for receiving a running length of traveling yarn therearound to frictionally clean dust and other undesirable particles from the yarn as the yarn travels therearound.
  • the assembly further includes a generally funnel-shaped, air suction conduit means secured to andsurrounding the outer periphery of one of the roller disc means and extending coaxially from the axis of rotation of the roller disc means for rotation with the roller disc means and for creating an air suction within and around the yarn receiving groove to remove the dirt and other particles cleaned from the yarn.
  • the assembly also includes a stationary air suction conduit means mounted coaxially with and extending from the rotary, funnel-shaped suction conduit means and being in cooperative suction communication therewith for receiving the dust and other particles therefrom.
  • the two cooperating rotary and stationary air suction conduit means create an air stream from within and around the yarn receiving and cleaning groove which flows coaxially with respect to the axis of rotation of the roller disc means from the groove and thereby provides complete dust and other foreign particle removal from the rotary roller discs and eliminates any clogging in the assembly which might prevent the free rotation of the roller discs.
