Process for making articles and apparatus
A process and an apparatus for producing hygienic absorbent articles provided with at least one refastenable side seam from a chain of articles being formed having a first elastic sheet and a second elastic sheet, wherein the process and the apparatus are configured to perform operations on one or both of the elastic sheets in a cross direction, that is, with the elastic sheets parallel to the machine direction.
1. A process for making hygienic absorbent articles provided with refastenable side seams from a chain of articles being formed having a first elastic sheet and a second elastic sheet, comprising:
keeping said first elastic sheet and said second elastic sheet in extended condition and superimposed on each other;
fixing at least one connecting element on a surface portion of said first elastic sheet, wherein said surface portion faces towards an outside of an assembly constituted by said first elastic sheet and said second elastic sheet superimposed;
cutting said first elastic sheet so as to obtain two end portions each provided with a respective connecting element of said at least one connecting element;
folding said end portions towards an inside of the assembly such that said respective connecting elements face towards said second elastic sheet;
connecting said end portions to said second elastic sheet through said respective connecting elements; and
cutting said second elastic sheet so as to separate one of said articles from said chain of articles being formed,
wherein said at least one connecting element makes said refastenable side seam.
2. The process of claim 1 , comprising cutting said second elastic sheet after connecting said end portions to said second elastic sheet by means of said respective connecting elements.
3. The process of claim 1 , comprising temporarily spacing said first elastic sheet and said second elastic sheet from each other while said end portions are folded.
4. The process of claim 1 , comprising folding said end portions by superimposing them onto respective portions of said first elastic sheet, wherein said folded end portions are configured to be part of distinct hygienic absorbent articles.
5. The process of claim 1 , comprising hiding said respective connecting elements from said second elastic sheet while said end portions are folded.
6. The process of claim 1 , comprising moving away said first elastic sheet from said second elastic sheet before cutting said first elastic sheet.
7. The process of claim 1 , wherein performing the processes of cutting said first elastic sheet and of folding said end portions comprises performing such processes along a curved path.
8. The process of claim 1 , comprising cutting said first elastic sheet along a cutting line passing through said at least one connecting element.
9. The process of claim 1 , comprising cutting said first elastic sheet along a cutting line positioned between two respective connecting elements adjacent to each other.
