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.
Claims5
A device for recompacting bales of resilient fibrous crop material such as hay, comprising:
- a recompaction chamber having top, bottom and end walls,
- a platen slidably positioned in said chamber, means for reciprocating said platen,
- entry means for introducing compressed bales of fibrous crop material into said chamber,
- discharge means for discharging recompacted bales from said chamber, banding means for automatically placing bands around said recompacted bale in planes lying generally parallel to the longitudinal axis of compressive movement of said platen,
- control means for partially retracting the platen to allow partial lengthwise expansion of the recompacted bale, and
- band guide means for guiding bands lengthwise around the recompacted bale, said band guiding means including a fixed track and at least one movable track operatively coupled to said fixed track for guiding the band between the two tracks during varying stroke lengths of said platen.
