Abstract
A spinning preparation machine for processing a fiber material includes a drafting system that moves the fiber material in a direction of conveyance and includes a plurality of roller pairs arranged one after the other with upper rollers and lower rollers. Elongated stripping devices having a stripping edge are in contact with the upper rolls to remove dirt and other contaminants therefrom. A suction hood is mounted above the stripping devices and is connected to a vacuum source. Each stripping device is mounted in an individual respective suction channel, and the stripping edge of the stripping device protrudes through a first opening in the respective suction channel. Each suction channel is mounted on a bottom wall having openings therein and includes a second opening opposite the first opening that is aligned opposite from one of the openings in the bottom wall. The suction hood protrudes beyond the openings in the bottom wall and is mounted on a side of the bottom wall opposite the suction channels.
