Abstract

A system and method for forming reinforced packages. The method can comprise forming an attached web by adhering a construct to a web of material, and moving the attached web in a downstream direction through at least a web edge forming assembly. The moving the attached web can comprise moving the construct with the web of material. The method further can include at least partially forming a folded web by folding at least a portion of the web of material as the attached web moves through the web folding assembly and forming a reinforced package comprising a liner and the construct by separating the liner from a remainder of the folded web. The construct is adhered to the liner.

First claim

What is claimed is:

1. A system for forming reinforced packages, the system comprising:
an attachment assembly receiving a web of material and a construct, the attachment assembly bringing the construct into engagement with the web of material for forming an attached web,
a web edge forming assembly disposed downstream from the attachment assembly, the web edge forming assembly receiving the attached web and comprising web folding features for folding at least a portion of the web of material to at least partially form a folded web;
a carton forming assembly comprising construct folding features for folding at least a portion of the construct over at least a portion of the folded web; and
a cutting assembly downstream from the web edge forming assembly and the carton forming assembly, the cutting assembly comprising cutting features for separating a liner from a remainder of the folded web to at least partially form a reinforced package comprising the liner attached to the construct.

2. The system of claim 1 , wherein the carton forming assembly is disposed downstream from the attachment assembly.

3. The system of claim 1 , wherein the carton forming assembly receives the attached web from the web edge forming assembly.

4. The system of claim 1 , further comprising a sealer assembly for forming at least one seal feature in the folded web, the sealer assembly comprising a heat seal roller and a heat seal arm, the heat seal roller rotating relative to the heat seal arm.

5. The system of claim 4 , wherein the heat seal roller is generally cylindrical, and the heat seal arm comprises a curved surface disposed proximate the heat seal roller so that at least a portion of the folded web is pressed between at least a portion of the heat seal arm and at least a portion of the outer surface of the heat seal roller as the heat seal roller is rotated.

6. The system of claim 1 , further comprising a blank conveyor for moving the construct to the attachment assembly, the blank conveyor comprising at least one lug belt with at least one lug for engaging the construct and moving the construct toward the attachment assembly.

7. The system of claim 6 , further comprising an adhesive applicator, wherein the blank conveyor is for moving the construct at least partially through the adhesive applicator and the attachment assembly, and the attachment assembly comprises at least one nip roller, the adhesive applicator being for applying adhesive to the construct and the at least one nip roller being for pressing the construct with the adhesive against the web of material as the blank conveyor moves the construct through the adhesive applicator and the attachment assembly.

8. The system of claim 1 , wherein web forming features of the web edge forming assembly comprise at least one guide roller and an inner forming plate at least partially extending over a central portion of the web of material, the at least one guide roller being for guiding a marginal portion of the web of material over the inner forming plate to at least partially form the folded web.

9. The system of claim 8 , wherein the web edge forming assembly further comprises a forming wheel disposed upstream from the at least one guide roller and the inner forming plate, the forming wheel being for at least partially engaging the central portion of the web of material during at least a portion of the folding the marginal portion of the web of material.

10. The system of claim 1 , wherein the carton forming assembly comprises an adhesive applicator for applying carton adhesive to at least an end panel of the construct and folding plates for folding at least the end panel relative to a remainder of the construct and positioning at least the end panel against the folded web.

11. The system of claim 1 , wherein the cutting assembly comprises a cutting roller for cutting the folded web.

12. The system of claim 1 , wherein the construct comprises a paperboard blank and the web of material comprises a flexible sheet of material.

13. The system of claim 1 , wherein the construct and the web of material comprise different materials.
