  • Patent number: 5249350
    Abstract: Recompressed rectilinear hay bales or split portions thereof have one or both opposed sides not supporting ties trimmed to provide new planar surfaces of fresher and more pleasing appearance. The process of forming such bales provides 1) placing an elongate field bale having spaced ties extending about four continuous sides in a recompression chamber, 2) removing the original ties from the bale while maintaining the compression, 3) recompressing the bale a direction parallel to its longer dimension by approximately sixty-five percent, 4) retying the recompressed bale with new ties on the same four continuous bale sides while maintaining the recompressed condition, 5) removing the recompressed bale from the recompressor and optionally cutting it into two similar parts between ties, 6) passing the bale or bale portions adjacent at least one saw blade to trim at least one original bale surfaces not supporting ties, and 7) removing the bale and trimmed material for further disposition.
