Method and system for forming packages
First Claim
1. A method of forming reinforced packages, the method comprising:
- forming an attached web by adhering a construct to a web of material, wherein the construct comprises a paperboard blank and the web of material comprises a flexible sheet of material;
moving the attached web in a downstream direction through at least a portion of a web edge forming assembly prior to a construct forming assembly, the moving the attached web comprising moving the construct with the web of material;
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 edge forming assembly;
forming a folded construct after the at least partially forming the folded web, the forming the folded construct comprising folding at least a portion of the construct to extend at least partially over the folded web as the attached web moves through the construct forming 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 being adhered to the liner.

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.

20. A method of forming reinforced packages, the method comprising:
-
forming an attached web by adhering a construct to a web of material; moving the attached web in a downstream direction through at least a web edge forming assembly and then a construct forming assembly, the moving the attached web comprising moving the construct with the web of material, wherein the web edge forming assembly comprises an inner forming plate at least partially extending over a central portion of the web of material, the inner forming plate being spaced apart from the central portion of the web of material at an upstream end of the web edge forming assembly and being positioned at an angle with respect to the central portion of the web of material so that the inner forming plate is closer to the central portion proximate a downstream end of the web edge forming assembly than at the upstream end of the web edge forming assembly; 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 edge forming assembly, wherein the at least partially forming the folded web comprises folding at least a marginal portion of the web of material to engage the inner forming plate at least partially over a central portion of the web of material, a gusset portion of the folded web extending upwardly from the central portion to the marginal portion, and moving the marginal portion downwardly toward the central portion on the inner forming plate as the folded web is moved in the downstream direction while pushing at least a portion of the gusset portion inwardly with an outer guide plate to form a gusset between the marginal portion and the central portion of the folded web, the gusset overlapping the central portion and the marginal portion overlapping the gusset; forming a folded construct after the at least partially forming the folded web, the forming the folded construct comprising folding at least a portion of the construct to extend at least partially over the folded web as the attached web moves through the construct forming 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 being adhered to the liner.
