This invention pertains to a bale forming apparatus for making rectangular bales from fibrous materials, such as, agricultural crops and industrial products. The principle mechanism consists of; a bale forming chamber and a feeder-compactor mechanism which perform a reversing oscillating motion relative to each other, depositing, and compressing layers of fibrous material in the bale forming chamber. The successive layers are arranged in a folded manner, in a continuous process, resulting in low power consumption and in high output capacity for the apparatus. This apparatus is especially suited to make large size rectangular bales.
