Abstract
The invention relates to a method of and apparatus for detecting unwanted material in the form of string or woven fabric in a flow of wanted fiber flocks or in a wanted fiber fleece. To this end, the flock flow is guided through a wave field which detects the presence of unwanted material in the flock flow so that the unwanted material can be separated out in a separator facility. The wave field can be an optical or acoustic wave field. The result obtained can, in addition to the separation of the unwanted material, be displayed in display means and/or recorded.
