Abstract

The machine has a frame with a crosswise beam to each end of which is mounted a rotary disc on upright axles. Two swathe-formers are suspended from the cross-bar. The guide-piece consists of flexible pieces, such as chains, hanging down. The chains are made up of flexible, tubular casings hinged to flat rods. The guide surface of the guide-device may be of flexible material such as rubber, canvas or plastic etc. and may be weighted down. The top edge of the guide-device may be reinforced. The guide-piece may be pivot-mounted, or rigidly fixed to the rotors, and is positioned above them placed in its operating position by centrifugal force. The guide has a cover fixed tot he hub of the rotary discs. The tines are pivot-mounted and are positioned into operating positions by centrifugal force.
