Abstract
A separating apparatus employs a foraminous drum with a resilient belt forming a nip therebetween. A take-up roller upstream of the nip is rotatably supported about a center of rotation that is parallel to, but offset from a central axis of the take-up roller. As the wobbling roller rotates, it constantly changes the point on the circumference of the foraminous drum at which contact is made with the resilient belt. This overcomes a tendency for entering items to bridge the nip.
