Abstract

Provided herein is a furniture wrapping system. The furniture wrapping system includes a film roll support configured to unroll a first film across a path of the furniture article in a first direction, such that the film roll support positions a film barrier across the path. The furniture wrapping system includes a conveyor mechanism configured to carry the furniture article along the path and into the barrier. The furniture wrapping system includes a sealer configured to extend across the path to form a seal such that the furniture article is partially enclosed in the first film.

First claim

What is claimed is:

1. A furniture wrapping system, comprising:
a first film and a second film;
an end sealer configured to seal the first film to the second film at a leading end to collectively extend transversely across a path of a furniture article to form a barrier and, subsequently, a trailing end of the furniture article with respect to the path;
a first longitudinal sealer configured to seal the first film to the second film longitudinally with respect to the path as the furniture article moves along the path; and
a conveyor mechanism that defines the path and is configured to drive the furniture article along the path into the barrier and past the first longitudinal sealer, such that the furniture article pushes the first film and the second film as the furniture article is moved into the barrier by the conveyor mechanism so that the first film and the second film envelop the furniture article, and such that the furniture article being pushed by the conveyor mechanism drags the first film and the second film through the first longitudinal sealer while the first longitudinal sealer seals the first film and the second film to each other along a longitudinal seal.

2. The furniture wrapping system of claim 1 , wherein the barrier across the path captures the furniture article as it moves along the path into the barrier.

3. The furniture wrapping system of claim 2 , further comprising a guide that engages the first and second films to guide the first and second films to direct them perpendicular to the path, forming the barrier across the path.

4. The furniture wrapping system of claim 1 , wherein the first longitudinal sealer comprises a heat sealer configured to weld portions of the first and second films together.

5. The furniture wrapping system of claim 1 , further comprising a third film disposed proximate the first film, wherein the third film is dispensed at an angle the same as the first film such that as the first film is depleted, the third film is configured to be fed at the same angle as the first film.

6. The furniture wrapping system of claim 1 , wherein the first film includes a first plastic layer of film and a second layer of a protective foam attached to one another.

7. The furniture wrapping system of claim 1 , wherein:
the first film includes a folded gusset;
the end sealer is configured to seal the first and second films with the gusset unfolded; and
the gusset has a width sufficient, when the gusset is unfolded, so that the first film is wide enough to extend over top of the furniture article to meet the second film at the first longitudinal sealer.

8. The furniture wrapping system of claim 1 , further comprising a second longitudinal sealer disposed on an opposite side of the path from the first longitudinal sealer and configured to form a second longitudinal seal on an opposite side of the furniture article from the first longitudinal sealer as the furniture article moves along the path.

9. The furniture wrapping system of claim 8 , wherein the conveyor mechanism includes a split conveyor having a first conveyor and a second conveyor with a gap therebetween, wherein the gap is positioned to receive the first and second films, and the second longitudinal sealer is disposed with respect to the gap to receive the first and second films through the gap to form the second longitudinal seal.

10. The furniture wrapping system of claim 1 , wherein:
the first film and the second film each have a gusset;
the end sealer is configured to seal the first and second films with the gussets of the first and second films unfolded; and
the gussets of the first and second films have a width sufficient so that the first and second films are wide enough to extend over top of the furniture article to meet at the first longitudinal sealer.

11. The furniture wrapping system of claim 10 , wherein the first and second films are sealed to form a continuous film attached at the leading end while the trailing ends remain gusseted.

12. The furniture wrapping system of claim 1 , wherein the first longitudinal sealer is disposed above the path to longitudinally seal the first and second films together on top of the furniture article.

13. The furniture wrapping system of claim 1 , wherein the first longitudinal sealer includes a rotating drum configured to rotate as the furniture article moves along the path.

14. The furniture wrapping system of claim 1 , wherein the first and second films are configured to slide across the first longitudinal sealer as the furniture article moves along the path.

15. The furniture wrapping system of claim 1 , wherein the first and second films are configured as rolls.

16. A furniture wrapping system, comprising:
a first film support configured to support a first film;
a second film support configured to support a second film;
an end sealer configured to seal the first film to the second film to form a leading end seal at a leading end of a furniture article along a path, the first and second film supports supporting the first and second films on opposite sides of the leading end seal so that the first and second films collectively extend transversely across the path to form a barrier, the end sealer also configured to seal the first film to the second film at a trailing end of the furniture article;
a longitudinal sealer configured to seal the first film to the second film longitudinally with respect to the path as the furniture article moves along the path; and
a conveyor mechanism that defines the path and is configured to drive the furniture article along the path into the leading end seal and, subsequently, past the longitudinal sealer such that the furniture article pushes the first film and the second film as the furniture article is moved into the barrier by the conveyor mechanism so that the first and second films envelop the furniture article, and such that the furniture article being pushed by the conveyor mechanism drags the first film and the second film through the longitudinal sealer while the longitudinal sealer seals the first film and the second film to each other along a longitudinal seal.

17. The furniture wrapping system of claim 10 , wherein:
the first film support comprises a first roll support;
the second film support comprises a second roll support;
the first film is configured as a first roll mounted on the first roll support; and
the second film is configured as a second roll mounted on the second roll support.

18. The furniture wrapping system of claim 16 , wherein:
the first film is configured as a first roll and includes a gusset formed by:
a first longitudinal fold, and
a second longitudinal fold parallel to the first longitudinal fold but folded in an opposite direction as the first longitudinal fold, wherein the first longitudinal fold and the second longitudinal fold wrap circumferentially around the first roll of the first film; and

the longitudinal sealer is disposed and configured to receive and longitudinally seal the first and second films with the gusset unfolded.

19. The furniture wrapping system of claim 18 , wherein the first film further comprises:
a third longitudinal fold parallel to the first and second longitudinal folds; and
a fourth longitudinal fold parallel to the third longitudinal fold but folded in the opposite direction as the third longitudinal fold, forming a second gusset therebetween.

20. The furniture wrapping system of claim 18 , wherein the first longitudinal fold is disposed on an exterior surface
