Fiber waste separator including carriers, movable covers, and suction hood

In a fiber processing machine including two oppositely rotated, tangentially cooperating first and second clothed rolls, wherein said first roll is an upstream roll and said second roll is a downstream roll as viewed in a travelling direction of fiber material being entrained by the rolls on fiber-advancing portions thereof;

• said rolls having a generally horizontal axis of rotation and together defining opposite first and second converging gaps;
• a first carrier disposed in said first converging gap and partially extending over a circumferential portion of said first and second rolls;
• the improvement comprising a mote knife mounted on said first carrier and bounding a waste discharge opening situated circumferentially along one of said rolls, further wherein said first carrier has a carrier part partially covering said fiber-advancing portion of said first roll;
• and an additional curved carrier part extending along a circumference of said second roll;
• said additional curved carrier part defining an air intake gap with said second roll;
• further comprising a second carrier disposed in said second converging gap;
• said second carrier having curved carrier parts extending over portions of circumferences of said first and second rolls.
