Abstract

A slip sheet pallet comprising a first sheet engageable with a stacked array which is to be supported; a second sheet attached to the first sheet; at least one flap connected to and extending outwardly from at least one of the first and second sheets and gripable by a lift truck gripping assembly; at least one of the first and second sheets comprising a compound sheet with a plurality of distinct connected layers.

Claims (26)

1. A slip sheet comprising:

a bottom sheet engagable with a lift truck platen, the bottom sheet having a central body portion and at least one flap connected to and extending outwardly from the bottom sheet, the flap adapted for gripping by a lift truck gripping assembly; and

a top sheet positioned in a overlying relationship with the central portion of the bottom sheet and engagable with a stacked array which is to be supported on the slip sheet, the top sheet including a top layer, a bottom layer, and an intermediate shock-dampening layer, the shock dampening layer extending substantially continuous and coextensive with the central body portion to provide substantially coextensive shock-dampening support to the stacked array over the central body portion.

2. The slip sheet of claim 1 , wherein the shock dampening layer comprises a honeycomb layer.

3. The slip sheet of claim 1 , wherein the shock dampening layer comprises a standing rib layer.

4. The slip sheet of claim 1 , wherein the shock dampening layer comprises a fluted layer.

5. The slip sheet of claim 4 , wherein the flutes extend laterally parallel to the flap.

6. The slip sheet of claim 4 , wherein the flutes extend perpendicularly to the flap.

7. The slip sheet of claim 4 , wherein the flutes extend diagonally to the flap.

8. The slip sheet of claim 1 , wherein the bottom sheet is comprised of plastic.

9. The slip sheet of claim 1 , wherein the top sheet is comprised of plastic.

10. The slip sheet of claim 9 , wherein the plastic is polypropylene.

11. The slip sheet of claim 1 , wherein the top sheet and the bottom sheet are attached by sonic welding.

12. The slip sheet of claim 1 , wherein the top sheet and the bottom sheet are attached by adhesive.

13. The slip sheet of claim 1 , wherein the top sheet and the bottom sheet are attached by friction.

14. The slip sheet of claim 1 , wherein the bottom sheet includes a plurality of downward projecting dimples distributed across the central body portion.

15. The slip sheet of claim 14 , wherein the dimples have a projection height of about 0.1 inches.

16. The slip sheet of claim 1 , wherein the central body portion is generally rectangular.

17. The slip sheet of claim 1 , wherein the top sheet is about one-half inch thick or less.

18. The slip sheet of claim 1 , wherein the material of the bottom sheet had a thickness of between about 0.05 inches and about 0.06 inches.

19. A slip sheet comprising:

a bottom sheet comprised of plastic and engagable with a lift truck platen, the bottom sheet having a central body portion and at least one flap connected to and extending outwardly from the bottom sheet, the flap adapted for gripping by a lift truck gripping assembly; and

a top sheet positioned in a overlying relationship with the central portion of the bottom sheet and engagable with a stacked array which is to be supported on the slip sheet, the top sheet including a top layer, a bottom layer, and an intermediate shock-dampening layer, the shock dampening layer extending substantially coextensive with the central body portion to provide substantially coextensive shock-dampening support to the stacked array over the central body portion.

20. A slip sheet comprising:

a bottom sheet engagable with a lift truck platen, the bottom sheet having a central body portion and at least one flap connected to and extending outwardly from the bottom sheet, the flap adapted for gripping by a lift truck gripping assembly; and

a top sheet comprised of plastic, the top sheet positioned in a overlying relationship with the central portion of the bottom sheet and engagable with a stacked array which is to be supported on the slip sheet, the top sheet including a top layer, a bottom layer, and an intermediate shock-dampening layer, the shock dampening layer extending substantially coextensive with the central body portion to provide substantially coextensive shock- dampening support to the stacked array over the central body portion.
