Title (EN) IMPROVEMENTS RELATING TO OPEN-END SPINNING MACHINES
(FR) AMELIORATIONS SE RAPPORTANT AUX MACHINES DE FILATURE "OPEN END"
Abstract: front page image
(EN)Apparatus for open-end spinning textile yarns of the friction spinning type includes a perforated drum (1) defining a yarn formation surface, a fibre feed duct (41) for conveying fibres onto the drum, and delivery rollers (55) for withdrawing yam therefrom. A duct member (13) extending into the drum is provided with a slot (14) for communicating suction to the perforated surface. To facilitate the setting and maintenance of the small clearance between the drum and the duct member, the drum is mounted for rotation on a bearing (20) ridigly carried by the duct member.
(FR)Un appareil pour des fils textiles de filature "open end" du type a filature a friction comprend un cylindre perfore (1) definissant une surface de formation des fils, une conduite d'alimentation des fibres (41) pour acheminer les fibres sur le cylindre, et des rouleaux (55) pour en retirer les fils. Un organe de conduite (13) s'etendant dans le cylindre est pourvu d'une fente (14) pour etablir la communication de l'aspiration sur la surface perforee. Pour faciliter le reglage et l'entretien du petit jeu entre le cylindre et l'organe de conduite, le cylindre est monte en rotation sur un palier (20) porte rigidement par l'organe de conduite.
