A multiposition open end spinning machine has a channel (31) running along the length of the machine to collect trash separated out at each position. A scraper (9) is drawn by a band drive (10) along the channel (31) to push the trash towards a waste suction. The width (b) of the channel (31) is wider than the trash spread region (32) so that there is a dead space (42) free of contaminants to accommodate the scraper drive (10).
