Abstract

Die Vorrichtung erzeugt mittels einer Beleuchtungseinrichtung (12-14) und einer Optik (16) vom Kardenvlies (1) eine optische Abbildung auf einem Array von Fotosensoren (17). Bei genügend kleiner Sensorfläche ist der durch Nissen verursachte zeitliche Verlauf der Beleuchtungsintensität für diese chrakteristisch und dient zu ihrer Erkennung. Die Nissen werden nicht ent­ fernt, ihre Häufigkeit gibt jedoch Hinweise auf mögliche Mängel an der Karde oder den vorgeschalteten Maschinen zur Faserauflösung. The device generates by means of a Lighting device (12-14) and optics (16) from Card fleece (1) an optical image on an array of photo sensors (17). With a sufficiently small sensor area is the time course caused by nits Lighting intensity for this characteristic and is used for their detection. The nits are not removed distant, but their frequency indicates possible Defects in the card or the upstream machines for fiber dissolution.
