Abstract
An apparatus for separating fibre material from an air stream or current of a penumatic transporting system contains a filter or perforated drum internally of which there prevails a vacuum. The fibre material drops from the drum at a take-off zone or region, in the form of a fibre layer or mat, into a receiving container or the like. This fibre layer is then removed from the receiving container, by using a plunger, and deposited, in an outfeed or delivery duct or channel. The spacing of the fibre take-off zone at the drum from the bottom or floor of the container is limited to a value which avoids tearing of the fibre layer or mat. Jamming or clogging of fibre material when using a rotating filter or perforated drum is avoided, since the take-off of the dropping or outbound fibre layer from the filter or perforated drum is perfected cleanly throughout. There results the advantage that danger of fires and damage, caused by fibre jamming, are essentially precluded. Since the dimensions of the receiving container can be maintained small there is also achieved a saving in space.
