摘要:
In the manufacture of friction spinning drums, in order to be able to select the size of the holes or perforations, on the one hand, to oppose technological fiber loss and jamming of sucked in foreign particles and, on the other hand, to provide airflow advantages, it is proposed to manufacture the friction spinning drum from a thick-walled support and a thin-walled perforated body. As a result, holes or perforations having a sufficiently small cross-section to counteract the above-mentioned fiber loss can be formed in the thin-walled perforated body. On the other hand, holes or perforations having a large enough cross-section to prevent jamming of sucked in foreign particles or other contaminants can be provided in the thick-walled support.
