Abstract
A system for packaging hay bales includes a press for compressing hay to small, compact bales and a wrapping machine which applies multiple sheets of a thin material to form a package of an effective strength that maintains the form and integrity of the hay bales, and prevents them from expanding back to their pre-compressed size. The wrapping machine applies the thin film to successive compressed hay bales such that the material extends therebetween to integrate multiple hay bales into a common bundle. A partial cutting machine positioned downstream of the wrapping machine cuts a portion of the material between adjacent hay bales to provide a detachable seam. A full cutting machine positioned downstream of the partial cutting machine completely cuts the material between selected pairs of adjacent wrapped hay bales to define sets of multiple wrapped hay bales.
