Abstract
Abstract A conveyor strip is adapted to be unwound from a shaft to extend the strip along a row of feeding places, the strip being supported on an underlayer on which the strip slides as it is wound upon or unwound from the shaft. Feed portioning means operate to deliver feed portions of predetermined weight successively upon the conveyor strip so that the feed portions are moved to the respective feed places by extending of the strip along the row.
