Abstract

A shipping system for shipping planar substrates includes a plurality of planar substrates stacked to form a pack and a plurality of interleaving material including substantially spherical beads positioned between the substrates of the pack and configured to carry a load. Substantially all of the beads have a diameter within 25% of Dmax, where Dmax is a diameter corresponding to a size of an opening of an upper limit sieve used in the shipping system. Also disclosed are a spacer for use in a shipping system for shipping planar substrates, a wrapped system for shipping planar substrates, a method of wrapping a system for shipping planar substrates, and a powder applicator.

First claim

The invention claimed is:

1. A shipping system for shipping planar substrates comprising:
a plurality of planar substrates stacked to form a pack; and
interleaving material comprising substantially spherical beads positioned between the substrates of the pack and configured to carry a load,
wherein substantially all of the beads have a diameter within 25% of D max , wherein D max is a diameter corresponding to a size of an opening of an upper limit sieve used to prepare the shipping system, the shipping system comprising a plurality of packs, each of the packs comprising an exposed face,
wherein the shipping system further comprises a spacer positioned between two of the packs, wherein the spacer comprises an area in contact with the exposed faces of the packs,
wherein each of the packs and substrates comprise a first region, a second region, and a third region between the first region and second region, and wherein the spacer is in contact with the exposed faces of at least one of the first regions and the second regions of the packs.

2. The shipping system of claim 1 , wherein the first regions and second regions of the packs and substrates range from 1% to 10% of the length, as measured from a first edge and second edge of the packs and substrates, respectively.

3. The shipping system of claim 1 , wherein the spacer comprises a first raised area in contact with the exposed faces of the first regions of the packs and a second raised area in contact with the exposed faces of the second regions of the packs.

4. The shipping system of claim 3 , wherein the first raised area and second raised area comprise a softer material compared to a material of the spacer.

5. The shipping system of claim 3 , wherein the spacer comprises an elongated portion positioned between the first raised area and second raised area, and wherein the elongated portion is not in contact with the exposed faces of the packs.

6. The shipping system of claim 1 , further comprising an A-frame configured to support the packs.

7. The shipping system of claim 6 , wherein the A-frame comprises a strut, the strut in contact with the exposed face of one of the packs.

8. The shipping system of claim 7 , wherein the strut comprises a plurality of raised regions, the raised regions comprising a softer material compared to a material of the strut,
wherein the raised regions comprise a first raised region and a second raised region, and wherein the first raised region is in contact with the exposed face of the first region of the pack in contact with the strut and the second raised region is in contact with the exposed face of the second region of the pack in contact with the strut.

9. The shipping system of claim 1 , wherein an interleaving material coverage between two of the substrates of one of the packs is 2 to 20 times greater between at least one of the first and second regions of the substrates compared to an interleaving material coverage of the interleaving material between the third regions of the substrates.
