US Patent 7478591 Twineball storage for balers

Cylindrical twineballs are stored on their sides with the twine dispensing end of each ball facing outwardly away from the baler to facilitate operator access. The twineballs are stored in a pattern consisting of horizontal rows and upright columns, with the upright columns inclined laterally so as to present an overall, generally skewed parallelogram effect to maximize the packing density within a given amount of space. The balls are supported within cradles that may advantageously be interconnected to present multiple, horizontally extending, transversely corrugated shelves. The shelves are upwardly and outwardly inclined to help retain the balls in place.
