ABSTRACT:
A method for improving the monitoring of the fill state of a sliver can (5) at a spinning station of a textile machine processing sliver wherein a defined portion (24 or 124) of a can bottom (22) is initially kept free from sliver (6) while a predetermined amount of sliver (6) is deposited on an adjoining portion (25 or 125) of the can bottom (22) and only after the adjoining portion (25 or 125) is covered with sliver, is the defined portion (24 or 124) covered with sliver (6). The method includes monitoring the defined (24 or 124) portion while the sliver is being drawn out and detecting when the defined portion of the can bottom (22) is uncovered to trigger a signal for exchanging an empty can for a filled sliver can. In one preferred embodiment, a sensor (27) for monitoring the defined portion (24 or 124) and detecting an uncovered can bottom is mounted on a service unit (16) which passes over the spinning stations. In another preferred embodiment, a sensor (127) is mounted on a spinning station (2) and continuously monitors the fill state of the sliver can (5).
