Abstract Foam buns are compressed for storage and/or shipment to reduce the volume of the buns. A power operated platen is disposed between adjacent buns to equalize the compression. Compression of the buns preferably takes place in the body of an over-the-road vehicle.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
107 words
A method of handling buns of compressible material comprising the steps of compressing first and second buns while moving the buns in a first direction by a platen, positioning third and fourth buns in the location formerly occupied by the first and second buns and on an opposite side of the platen with respect to the first and second buns, and then compressing the third and fourth buns while partially decompressing the first and second buns to substantially equalize the amount of compression of all buns, said step of compressing the third and fourth buns including moving the platen in a direction opposite to the first direction.
Claim 2
Independent Claim
107 words
A method of handling buns of compressible material comprising the steps of compressing first and second buns while moving the buns in a first direction by a platen, positioning third and fourth buns in the location formerly occupied by the first and second buns and on an opposite side of the platen with respect to the first and second buns, and then compressing the third and fourth buns while partially decompressing the first and second buns to substantially equalize the amount of compression of all buns, said step of compressing the third and fourth buns including moving the platen in a direction opposite to the first direction.
Claim 3
Dependent Claim
32 words
A method in accordAnce with claim 1 wherein said step of compressing the first and second buns includes compressing foam buns so that the buns are less than one-half their original thickness.
Claim 4
Dependent Claim
38 words
A method in accordance with claim 1 wherein the buns are of a geometric shape having generally planar upper and lower surfaces, and transporting the buns while the buns are subjected to a substantially equal amount of compression.
Claim 5
Dependent Claim
41 words
A method in accordance with claim 1 wherein said step of moving the buns in a first direction includes moving the buns upwardly, and said step of partially decompressing the first and second buns includes allowing the buns to expand downwardly.
Claim 6
Dependent Claim
29 words
A method in accordance with claim 1 including performing the compressing and decompressing steps of the buns while the buns are disposed within a body of an over-the-road trailer.
Claim 7
Independent Claim
84 words
A method of handling foam buns comprising the steps of compressing first and second buns of foam polymeric material by moving the buns upwardly, positioning third and fourth buns in the space formerly occupied by the first and second buns, compressing the third and fourth buns upwardly, positioning a fifth bun in the space formerly occupied by the above-mentioned buns, and compressing the fifth bun downwardly while permitting the remaining buns to decompress so that all buns are compressed to substantially the same amount.
Claim 8
Independent Claim
84 words
A method of handling foam buns comprising the steps of compressing first and second buns of foam polymeric material by moving the buns upwardly, positioning third and fourth buns in the space formerly occupied by the first and second buns, compressing the third and fourth buns upwardly, positioning a fifth bun in the space formerly occupied by the above-mentioned buns, and compressing the fifth bun downwardly while permitting the remaining buns to decompress so that all buns are compressed to substantially the same amount.
Claim 9
Dependent Claim
21 words
A method in accordance with claim 6 including performing the compressing and decompressing steps within the body of an over-the-road vehicle.
