Claims
- 1. A method of applying an elastic segment of sheet material having a leading end and a trailing end unattached to the leading end to the surface of an article, said method comprising:(1) stretching the segment to elastically deform the segment and increase the distance between the leading and trailing ends, (2) applying said segment while so stretched to the article by adhering the leading end of the stretched segment to the article with a fast acting adhesive which substantially adheres the leading end of the stretched segment to the article while the stretched segment is in an elastically deformed condition, wrapping the stretched segment around said article and securing the trailing end of the stretched segment to said leading end or to the article, whereby said segment as applied to the article is in the elastically deformed condition.
- 2. The method of claim 1 wherein the article is a container and the segment is a label.
- 3. The method of claim 1 or claim 2 in which the segment is severed from a continuously moving length of sheet material which is deposited on the cylindrical surface of a continuously rotating vacuum drum and is rotated to a segment applying station at which each segment is released from the vacuum drum to a spinning article which wraps the segment about itself, the segment being in such stretched condition while being so applied to the spinning article.
- 4. The improvement of claim 3 in which each segment is stretched by at least one of the following means;(1) rotating the vacuum drum at a peripheral speed greater than the speed of the sheet material; (2) moving each article as a segment is applied to it at a surface speed greater than the peripheral speed of the vacuum drum.
- 5. The improvement of claim 4 wherein the article is a container and the segment is a label.
- 6. The method of claim 1 or claim 2 wherein the article is a container for a carbonated beverage.
- 7. The method of claim 1 in which said step of applying said segment includes applying an adhesive only to the leading end and the trailing end of said segment, said adhesive being a fast acting adhesive such that said adhesive forms a bond before the stretched segment relaxes.
- 8. The method of claim 1 in which said step of applying said segment includes applying adhesive to the underside of the stretched segment in a plurality of locations.
- 9. A method of applying a segment of a sheet of material to the exterior surface of an article, said segment having a leading edge and a trailing edge, said method comprising the steps of:releasably mounting a segment of said elastic material to a carrier body, stretching the segment to elastically deform said segment and increase the length between said leading edge and said trailing edge, applying an adhesive to one of said article and said leading edge of the elastically deformed segment and mounting said leading edge to said article with said adhesive, said adhesive being a fast acting adhesive such that said leading edge is substantially secured to said article before said segment is released from said carrier body, producing relative movement of said carrier body and said article to wrap the elastically deformed segment around said article, successive portions of the elastically deformed segment being released from said carrier body as the elastically deformed segment is wrapped around said article, and applying an adhesive to one of said article and said trailing edge of the elastically deformed segment and mounting said trailing edge to one of said article and said segment with said adhesive, said adhesive being a fast acting adhesive such that said trailing edge is secured to said article before said trailing edge is released from said carrier body.
- 10. The method of claim 9 in which said releasably mounting step includes applying said segment to a vacuum drum.
- 11. The method of claim 9 in which said stretching step includes moving each article as the elastically stretch segment is applied to said article at a surface speed greater than the speed of said carrier body.
- 12. The method of claim 9 in which said stretching step includes retaining said segment in the elastically deformed condition by holding the elastically deformed segment against said carrier body by at least one of a vacuum and a clamping mechanism.
- 13. The method of claim 9 in which said step of applying said segment includes applying adhesive to one of said article and segment in a plurality of circumferentially spaced locations.
- 14. The method of claim 9 wherein the article is a container and the segment is a label.
- 15. A method of applying a segment of a sheet of material to the exterior surface of an article, said segment having a leading edge and a trailing edge, said method comprising the steps of:releasably mounting a segment of said elastic material to a carrier body, stretching the segment to elastically deform said segment and increase the length between said leading edge and said trailing edge, applying an adhesive to one of said article and said leading edge of the elastically deformed segment and mounting said leading edge to said article with said adhesive, said adhesive substantially securing said leading edge to said article before said segment is released from said carrier body, producing relative movement of said carrier body and said article to wrap the elastically deformed segment around said article, successive portions of the elastically deformed segment being released from said carrier body as the elastically deformed segment is wrapped around said article, applying an adhesive to one of said article and said trailing edge of the elastically deformed segment and mounting said trailing edge to one of said article and said segment with said adhesive, said adhesive substantially securing said trailing edge to said article before said trailing edge is released from said carrier body, said stretching step including supplying said segment to the exterior surface of said carrier body at a first speed and rotating said carrier body at a velocity such that the exterior surface moves at a second speed greater than said first speed to elastically deform said segment.
