Abstract
A method of making a multiple ply slotted partition for use in a slotted partition assembly is provided. The slots of the partitions are engaged with each other at a plurality of intersections. The partitions are made by folding over a partition blank and securing a foam portion of the folded partition blank to itself. The foam may be heated before being cooled to secure opposed plies of the multiple ply partition together. The opposed plies of the partition are fused or parent welded together.
Claims32
A method of forming a partition, the method comprising the steps of:
- providing a multiple layered partition blank having a foam layer having opposed first and second surfaces and an outer layer bonded directly to the second surface of the foam layer;
- folding the partition blank so the first surface of the foam layer of the partition blank contacts itself to create two opposed plies and a rounded edge;
- parent welding the opposed plies together into a two-ply partition;
- and
- creating a plurality of spaced slots extending inwardly from the rounded edge of the two-ply partition by slotting the two-ply partition.
A method of forming a partition comprising the steps of:
- providing a partition comprising an inner foam layer and an outer layer which is not foam;
- using a press to contact the outer layer and fold the partition blank so as to create two opposed plies and a rounded edge;
- fusing the opposed plies together such that the inner foam layer of one ply is fused to the inner foam layer of the other ply;
- and
- creating a plurality of spaced slots extending inwardly from the rounded edge of the two-ply partition by slotting the two-ply partition.
A method of forming a partition, the method comprising the steps of:
- providing a multiple layered partition blank having a foam layer having opposed first and second surfaces and an outer non-foam layer bonded directly to the second surface of the foam layer;
- folding the partition blank so the first surface of the foam layer of the partition blank contacts itself to create two opposed plies and a rounded edge;
- parent welding the opposed plies together into a two-ply partition;
- and
- creating a plurality of spaced slots extending inwardly from the rounded edge of the two-ply partition by slotting the two-ply partition.
A method of forming a partition, the method comprising the steps of:
- providing a multiple layered partition blank having a foam layer having opposed first and second surfaces and an outer layer bonded directly to the second surface of the foam layer;
- folding the partition blank so as to create two opposed plies and a rounded smooth edge joining the plies;
- heating at least one foam interior layer of the opposed plies;
- contacting the first surface of the foam layer of the partition blank to itself;
- and
- cooling the opposed plies together into a two-ply partition.
