Claims
- 1. A method of making an absorbent article comprising at least one laterally extending side tab wherein separate, discrete patches of adhesive are applied to said article and said tab, such method comprising the steps of:
- a) forming a central portion having an absorbent element;
- b) depositing a first patch of adhesive on a first side of a release strip so that said first patch of adhesive bonds thereto;
- c) attaching said release strip to said central portion by placing said first side of the release strip onto said central portion so that said first patch of adhesive bonds to said central portion more tenaciously than said first patch of adhesive bonded to said release strip;
- d) depositing a second discrete patch of adhesive on a second side of said release strip so that said second patch of adhesive bonds thereto, the step of depositing said second patch of adhesive being performed after the step of attaching said release strip to said central portion; and
- e) placing a tab adapted to be folded around a crotch of a user's undergarment onto said second side of said release strip so that said second patch of adhesive bonds to said tab more tenaciously than said second patch of adhesive bonded to said release strip, the step of placing said tab onto said second side of said release strip being performed after the step of depositing said second patch of adhesive on said second side of said release strip;
- whereby said first and second patches of adhesive remain on said central portion and said tab, respectively, when said strip is removed from said article.
- 2. The method according to claim 1, wherein said adhesive comprises a pressure sensitive hot melt glue.
- 3. The method according to claim 1, further comprising the step of coating said first and second sides of said strip with a second material.
- 4. The method according to claim 3, wherein said second material is a release agent that causes said first and second patches of adhesive to preferentially bond with greater tenacity to said central portion and said tab, respectively, than to said first and seconds sides of said strip.
- 5. The method according to claim 3, wherein said second material comprises a silicone coating.
- 6. The method according to claim 1, wherein the step of forming said central portion comprises the step of enclosing at least a portion of said absorbent element with a layer of a second material, and further comprising the step of forming said tab from said layer of second material.
- 7. The method according to claim 6, wherein the step of placing said tab on said second side of said strip further comprises the step of placing said tab so that said second patch of adhesive bonds to said layer of second material.
- 8. The method according to claim 6, wherein said central absorbent has a longitudinal side, and wherein the step of forming said central portion comprises the step of enclosing at least a portion of said absorbent element with a layer of said second material so that a portion of said layer of second material extends beyond said longitudinal side, and wherein the step of forming said tab from said portion of said layer of second material comprises forming said tab from said portion of said layer of second material extending beyond said longitudinal side.
- 9. The method according to claim 8, wherein the step of placing a tab on said second side of said strip comprises the step of folding said tab over said central portion.
- 10. The method according to claim 1, wherein said tab comprises a layer of a second material, and wherein the step of placing said tab on said second side of said strip further comprises the step of placing said tab so that said second patch of adhesive bonds to said layer of second material.
- 11. The method according to claim 10, wherein said second material is formed from a polymeric film.
- 12. A method of making an absorbent article comprising at least one side tab wherein separate, discrete patches of adhesive are applied to said article and said tab, such method comprising the steps of:
- a) forming a central portion by covering an absorbent element with a layer of material so that a first portion of said layer extends laterally right and left from said central portion, thereby forming right and left tabs adapted to wrap around a crotch of a user's undergarment;
- b) depositing a first patch of adhesive on a first side of a double-sided release strip so that said first patch of adhesive bonds thereto;
- c) placing said first side of said release strip on said first portion of said layer of material after said first patch of adhesive has been deposited on said first side of said release strip so that said first patch of adhesive bonds to said layer of material with greater tenaciously than said first patch of adhesive bonds to said release strip;
- d) depositing a second patch of adhesive on a second side of said release strip after said release strip has been placed on said first portion of said layer of material so that said second patch of adhesive bonds thereto; and
- e) folding said tabs over said second side of said release strip after said second patch of adhesive has been deposited on said second side of said release strip so that said second patch of adhesive bonds to said first portion of said layer that forms said tabs with greater tenaciously than said second patch of adhesive bonded to said release strip;
- whereby said first and second patches of adhesive remain on said central portion and said tab, respectively, when said strip is removed from said article.
- 13. The method according to claim 12, wherein said adhesive is a pressure sensitive hot melt glue.
- 14. The method according to claim 13, wherein said layer of material is formed from a polymeric film.
- 15. In a method of making an absorbent article comprising a tab extending from a central portion, wherein separate, discrete patches of adhesive are applied to said article and said tab, a method of applying adhesive to said tab for attaching said tab to a user's undergarments, comprising the steps of:
- a) attaching a first side of a double-sided release strip to a central portion having an absorbent;
- b) depositing an adhesive on a second side of said release strip after said release strip has been attached to said central portion so that said adhesive bonds thereto; and
- c) transferring said adhesive to said tab by placing said tab against said second side of said release strip after said adhesive has been deposited onto said second side of said release strip so that said adhesive bonds to said tab, whereby when said release strip is detached from said central portion said adhesive preferentially remains bonded to said tab rather than to said release strip.
- 16. The method according to claim 15, wherein said adhesive is a hot melt glue.
- 17. The method according to claim 16, wherein:
- a) said tab is comprised of a layer of material formed from a polymeric film; and
- b) the step of transferring said adhesive to said tab comprises the step of placing said layer of material against said second side of said release strip so that said adhesive bonds to said polymeric film.
