  • Patent number: 4785730
    Abstract: A baling machine according to the invention has a frame having walls defining an elongated compaction chamber having a front end provided with a transversely open intake to which a stream of crop is fed substantially continuously. At least one compacting member is periodically displaced in the chamber between a front position forward of the intake and a back position rearward of the intake by an appropriate drive so as to rearwardly compact crop in the chamber. A plurality of pushers are each displaceable between an advanced position projecting into the chamber and only partially blocking the intake and a retracted position substantially out of the chamber by a linkage that advances the pushers into their advanced position only when the member is rearward of the intake and of the pushers. Thus advance of the pushers into the advanced position immediately after movement of the compacting member rearward past the pushers parts the stream of crop between the pushers and compacting member.
