Abstract
A method for converting low-density objects into a bale that is suitable for transportation and storage. A bale made in accordance with the method of the invention comprises a first compressed biscuit having a recessed groove; a second compressed biscuit adjacent the first biscuit and a strapping means inserted into the groove and extending circumferentially around the first and second biscuits. The invention is particularly useful for making bales of compressed biscuits from recycled aluminum containers.

A method for converting low-density objects into a bale that is suitable for transportation and storage, comprising
- (a) providing a chamber having a base wall, a side wall extending outwardly from said base wall, said side wall defining a mouth opening spaced outwardly from said base wall,
- (b) inserting a first plurality of low-density objects through said mouth opening and into said chamber,
- (c) compressing said low-density objects by applying force to a crusher having a platen provided with a principal surface opposed to said base wall and a protuberance extending inwardly from said principal surface toward said base wall, said protuberance comprising a first lateral portion and a second lateral portion spaced from said first lateral portion, said platen further comprising a first chamfer extending obliquely inwardly and laterally from said principal surface toward said side wall, said platen forming a compressed first biscuit having a density greater than the density of said objects inserted into the chamber in step (b), said platen forming in said first biscuit a first wall including a recessed groove suitable for insertion of a strapping means, said first chamfer forming in said first biscuit a first bevel extending obliquely inwardly and laterally from said first wall toward said side wall, said first biscuit further comprising a second wall spaced inwardly from said first wall and adjacent said base wall of the chamber,
- (d) forming a compressed second biscuit by compressing a second plurality of low-density objects,
- (e) positioning said first and second biscuits adjacent one another with said second wall adjacent said second biscuit and said first wall spaced from said second biscuit,
- (f) inserting a first strapping means into said groove, said first strapping means extending circumferentially around said first and second biscuits, and
- (g) binding said first and second biscuits into a bale by fastening said first strapping means to said biscuits.
