Abstract

A system and method of at least partially forming reinforced packages. The method comprises moving a construct in a machine direction on a construct conveyor. The construct conveyor can comprise a primary lug belt with a primary lug, the construct can be disposed on the primary lug belt, and the moving the construct can comprise moving the primary lug belt in the machine direction to push the construct in the machine direction. The method further can comprise positioning a liner on the construct conveyor so that the liner at least partially extends over the construct and moving the liner in the machine direction on a secondary lug belt of the construct conveyor. The secondary lug belt can comprise a secondary lug and the moving the liner can comprise moving the secondary lug belt in the machine direction to push the liner in the machine direction.

First claim

What is claimed is:

1. A method of at least partially forming reinforced packages, the method comprising:
moving a construct in a machine direction on a construct conveyor, the construct conveyor comprising a primary lug belt with a primary lug and a secondary lug belt with a secondary lug, the construct being disposed on the primary lug belt, and the moving the construct comprising moving the primary lug belt in the machine direction so that the primary lug pushes the construct in the machine direction;
positioning a liner on the construct conveyor so that at least a portion of the liner extends over at least a portion of the construct; and
moving the liner in the machine direction on the secondary lug belt of the construct conveyor, moving the liner comprises moving the secondary lug belt in the machine direction so that the secondary lug pushes the liner in the machine direction, wherein portions of the primary lug belt and the secondary lug belt extend below the liner and the construct during the moving the liner in the machine direction on the secondary lug belt.

2. The method of claim 1 , wherein the positioning the liner comprising positioning the liner to be spaced downstream from the secondary lug and then aligning the liner for attachment to the construct.

3. The method of claim 2 , wherein the aligning the liner comprises at least partially restraining the liner from moving in the in the machine direction until the secondary lug engages an upstream edge of the liner.

4. The method of claim 3 , wherein the at least partially restraining the liner comprises engaging the liner with a brush that is stationary with respect to the secondary lug belt.

5. The method of claim 3 , further comprising applying adhesive to the construct as the construct moves in the machine direction prior to the positioning the liner.

6. The method of claim 5 , further comprising nipping the liner and the construct between nip rollers after the aligning the liner.

7. The method of claim 3 , wherein the secondary lug is offset from the primary lug and the aligning the liner comprises engaging upstream edges of the construct and liner with the respective primary lug and secondary lug so that the upstream edges are spaced from one another by the offset between lugs when the liner is attached to the construct.

8. The method of claim 1 , wherein the secondary lug is offset from the primary lug so that the liner is aligned for attachment to the construct when a first edge of the construct engages the primary lug and a second edge of the liner engages the secondary lug.

9. The method of claim 8 , wherein the secondary lug is offset upstream from the primary lug.

10. The method of claim 1 , wherein the moving the liner in the machine direction comprises supporting at least a portion of the liner on a liner guide that extends above the construct along at least a portion of the construct conveyor.

11. The method of claim 10 , wherein the moving the liner in the machine direction comprises supporting at least a portion of the liner on a cantilever support that extends above the construct along at least a portion of the construct conveyor, the cantilever support supporting an inner portion of the liner and the liner guide supporting an outer portion of the liner.

12. The method of claim 11 , further comprising applying adhesive to the construct prior to the positioning the liner and nipping the liner and the construct between nip rollers after the positioning the liner, the cantilever support extending to a point that is upstream from the nip rollers.

13. The method of claim 1 , wherein the construct conveyor comprises two liner guides and two construct guides, the two liner guides are spaced inwardly and upwardly from the two construct guides, the moving the construct in the machine direction comprising supporting at least a portion of the construct on the two construct guides, and the moving the liner in the machine direction comprises supporting at least a portion of the liner on the two liner guides above the construct.

14. The method of claim 1 , further comprising moving the liner on a first liner conveyor and a second liner conveyor prior to the positioning the liner, the first liner conveyor extending transverse to the machine direction and the second liner conveyor moving in the machine direction.

15. The method of claim 14 , wherein the first liner conveyor receives the liner from a liner forming section, the second liner conveyor receives the liner from the first liner conveyor, and the positioning the liner on the construct conveyor comprises moving the liner from the second liner conveyor to the construct conveyor.

16. A system for at least partially forming reinforced packages, the system comprising:
a construct conveyor comprising a primary lug belt with a primary lug and a secondary lug belt with a secondary lug, the construct conveyor moving the primary lug belt and the secondary lug belt in a machine direction;
a construct positioned on the construct conveyor, the primary lug pushing the construct the machine direction; and
a liner positioned on the construct conveyor and at least partially overlapping the construct, the secondary lug pushing the liner in the machine direction, wherein portions of the primary lug belt and the secondary lug belt extend below the construct and the liner.

17. The system of claim 16 , wherein the secondary lug is spaced upstream from the primary lug, the primary lug engages an upstream edge of the construct, and the secondary lug engages an upstream edge of the liner when the liner is aligned for attachment to the construct.

18. The system of claim 16 , wherein the construct conveyor further comprises a brush that engages the liner to at least partially restrain the liner until the liner is aligned for attachment to the construct, the secondary lug pushing the liner in the machine direction against the brush when the liner is aligned for attachment to the construct.

19. The system of claim 18 , wherein the brush is stationary with respect to the secondary lug belt.

20. The system of claim 18 , further comprising an adhesive applicator that applies adhesive to the construct as the primary lug pushes the construct in the machine direction, the adhesive applicator being upstream from the secondary lug belt.

21. The system of claim 20 , further comprising a nip roller that nips the liner and the construct together when the liner is pushed by the secondary lug and the construct is pushed by the primary lug.

22. The system of claim 16 , wherein the secondary lug is offset from the primary lug so that the liner is aligned for attachment to the construct when a first edge of the construct engages the primary lug and a second edge of the liner engages the secondary lug.

23. The system of claim 22 , wherein the secondary lug is offset upstream from the primary lug.

24. The system of claim 16 , wherein the construct conveyor further comprises a liner guide that supports at least a portion of the liner over the construct, the liner guide extending above the construct along at least a portion of the construct conveyor.

25. The system of claim 24 , wherein the construct conveyor further comprises a cantilever support that supports at least an inner portion of the liner over the construct, the cantilever support extending above the construct along at least a portion of the construct conveyor, and the liner guide supporting a
