  • Separating apparatus with wobbling take-up roller
    Patent number: 4899890
    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.

  • Separating apparatus with wobbling take-up roller
    Patent number: 4819811
    Abstract: A separating machine of a type having a foraminous drum with a resilient belt forming a nip therebetween includes a take-up, roller upstream of the nip, having an axis skewed with respect to an axis of the take-up roller. The wobbling motion of the take-up roller distorts the resilient belt sufficiently to overcome a tendency for entering items to bridge the nip.
