Abstract
A method of forming reinforced packages. The method can comprise moving a blank in a machine direction on a blank conveyor, and forming a tubular web while moving a first web of material and a second web of material in the machine direction. The forming the tubular web can comprise at least partially sealing at least a portion of the first web and the second web together to form a sealed margin of the tubular web. The method further can comprise forming a liner by cutting the tubular web, forming an attached blank by attaching the liner to the blank, and moving the attached blank in the machine direction on the blank conveyor.
Claims33
A method of forming attached blanks, the method comprising:
- moving a blank in a machine direction on a blank conveyor;
- forming a tubular web while moving a first web of material and a second web of material in the machine direction, the forming the tubular web comprising at least partially sealing at least a portion of the first web and the second web together to form a sealed margin of the tubular web;
- forming a hem by folding the sealed margin into face-to-face contact with a surface of the tubular web after the forming the tubular web;
- forming a liner by cutting the tubular web;
- forming an attached blank by attaching the cut liner to the blank;
- and
- moving the attached blank in the machine direction on the blank conveyor.
A system for forming attached blanks, the system comprising:
- a blank conveyor moving a blank in a machine direction to an attachment station;
- a liner-forming assembly moving a first web and a second web in the machine direction, the liner-forming assembly comprising:
- a sealing station forming the first web and the second web into a tubular web, the sealing station comprising a sealer that at least partially engages the first web and the second web to at least partially seal at least a portion of the first web and the second web together to form a sealed margin of the tubular web;
- a folding station downstream from the sealing station, the folding station forming a hem in the tubular web by folding the sealed margin into face-to-face contact with a surface of the tubular web after the sealing station forms the tubular web;
- a cutting station that receives the tubular web and comprises cutting features cutting the tubular web to form a liner;
- and
- an attachment station receiving the cut liner and the blank and attaching the cut liner to the blank to form an attached blank, the blank conveyor moving the attached blank in the machine direction.
