Abstract
Bulk material that is difficult to feed, such as glass fibers, is fed from a storage bin into a feeding chute driven by a vibratory drive which vibrates the chute in a longitudinal direction of the chute, that is, in the feed advance direction of the chute. The chute may be a so-called loss-in-weight feeding chute. In order to assure a uniform, constant material flow without any bunching and without any gaps in the flow for an accurate feeding, the material flow is exposed or influenced by a further vibration effective in a direction substantially across the feed advance direction. For the purpose a vibrator with vibrating elements extending in the feed advance direction vibrates in the cross-direction. These vibrating elements are so located that they can make the material flow through the chute more uniform.
