Method of assembling a double-walled container
A method of making a double-wall cup having an inner cup defining an inner wall and an outer wrapper defining an outer wall, the method comprising applying an adhesive on the inner wall, holding a portion of the wrapper, at a location between opposing ends of the wrapper, in contact with the adhesive while in spaced relationship with the inner wall to define a spaced condition, and wrapping the wrapper about the inner wall.
1. A method of making a double-wall cup having an inner cup defining an inner wall and an outer wrapper defining an outer wall, the method comprising:
applying an adhesive on the inner wall;
holding, by a suction force, a portion of the wrapper in place against a suction arm, the suction arm contacting the wrapper to provide the suction force at a point centrally located between opposing ends of the wrapper, the portion of the wrapper held in contact with the adhesive while in spaced relationship with the inner wall to define a spaced condition such that the adhesive is not substantially compressed;
wrapping the opposing ends of the wrapper about the inner wall until the opposing ends overlap one another to define an overlapped portion, while holding, by the suction force, the wrapper in the spaced condition;
holding a press arm against the overlapped portion for a length of time to complete the wrapping, such that the overlapped portion does not move toward the inner wall; and
ceasing the suction force to the wrapper by the suction arm when the wrapping is completed.
2. The method of claim 1 wherein the applying the adhesive comprises multiple discrete applications of adhesive.
3. The method of claim 2 wherein the multiple discrete applications of adhesive comprise at least one of: dots, circles, or lines.
4. The method of claim 1 further comprising applying adhesive to at least one of the opposing ends along at least a portion of the overlapped portion.
5. The method of claim 4 wherein the applying adhesive to at least one of the opposing ends occurs prior to the overlapping of the opposing ends.
6. The method of claim 1 wherein the length of time comprises a suitable length of time for the overlapped portion to be sufficiently adhered together.
7. The method of claim 1 wherein the suction arm comprises a base portion and an angled portion that can be provided at an angle relative to the base portion.
8. The method of claim 7 wherein the angle of the angled portion relative to the base portion can be adjusted to accommodate a pitch of the double-wall cup.
9. The method of claim 7 wherein at least one suction nozzle extends from an upper surface of the angled portion to provide the suction force to the wrapper.
10. A method of making a double-wall cup comprising:
applying a spacer to an inner wall of a sleeve;
holding, by a suction force, a portion of a wrapper in place against a suction arm, the suction arm contacting the wrapper to provide the suction force at a point centrally located between opposing ends of the wrapper, the portion of the wrapper held in contact with the spacer while in spaced relationship with the inner wall to define a spaced condition such that the spacer is not substantially compressed;
wrapping the opposing ends of the wrapper about the inner wall until the opposing ends overlap one another to define an overlapped portion, while holding, by the suction force, the wrapper in the spaced condition;
holding a press arm against the overlapped portion for a length of time to complete the wrapping, such that the overlapped portion does not move toward the inner wall; and
ceasing the suction force to the wrapper by the suction arm when the wrapping is completed.
11. The method of claim 10 further comprising affixing a bottom to the sleeve to form an inner cup comprising the sleeve and the bottom.
12. The method of claim 10 wherein the applying the spacer comprises multiple discrete applications of spacers.
13. The method of claim 12 wherein the multiple discrete applications of spacers comprise at least one of: dots, circles, or lines.
14. The method of claim 10 further comprising applying adhesive to at least one of the opposing ends along at least a portion of the overlapped portion.
15. The method of claim 14 wherein the applying adhesive to at least one of the opposing ends occurs prior to the overlapping of the opposing ends.
16. The method of claim 10 wherein applying the spacer comprises applying at least one of an adhesive, a bead, a strip of foam, or a protruding structural member.
17. The method of claim 10 wherein the length of time comprises a suitable length of time for the overlapped portion to be sufficiently adhered together.
18. The method of claim 10 wherein the suction arm comprises a base portion and an angled portion that can be provided at an angle relative to the base portion.
19. The method of claim 18 wherein the angle of the angled portion relative to the base portion can be adjusted to accommodate a pitch of the double-wall cup.
20. The method of claim 18 wherein at least one suction nozzle extends from an upper surface of the angled portion to provide the suction force to the wrapper.
