Abstract
Abstract Bales of hay and the like which were bundled or baled in the field are recompressed to about one-half their original length by using a high-pressure ram on the bales after their wires have been cut and removed, over-compressing the bales and then after relaxing the over-compression, restrapping the recompacted bale through a set of strap guides which are automatically adjusted in the direction of the press stroke to guide the strap around the recompacted bale regardless of the amount of over-compression of the bale.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
98 words
A method of recompacting field-baled and banded bundles of fibrous crops comprising: confining the bundle, unbanding the bundle, compressing the unbanded bundle at a recompacting station in a direction generally perpendicular to the alignment of the fibers in the bundle, over-compressing to break down a substantial amount of the fibers to partially destroy their resiliency, reducing the pressure on the bundles after over-compressing to relieve the internal expansion stresses within the bundle, and guiding a band continuously around the entire recompacted bundle while in said recompacting station and while held at said reduced pressure to reband the bundle.
Claim 2
Independent Claim
98 words
A method of recompacting field-baled and banded bundles of fibrous crops comprising: confining the bundle, unbanding the bundle, compressing the unbanded bundle at a recompacting station in a direction generally perpendicular to the alignment of the fibers in the bundle, over-compressing to break down a substantial amount of the fibers to partially destroy their resiliency, reducing the pressure on the bundles after over-compressing to relieve the internal expansion stresses within the bundle, and guiding a band continuously around the entire recompacted bundle while in said recompacting station and while held at said reduced pressure to reband the bundle.
Claim 3
Dependent Claim
25 words
The method of claim 1, said band guiding step including forming a continuous guide path around the recompacted bundle during variable amounts of pressure reduction.
