AS A RESULT OF REEXAMINATION, IT HAS BEEN DETERMINED THAT: |
Claims 1, 12 and 13 are determined to be patentable as amended. |
Claims 2-11 and 14-16, dependent on an amended claim, are determined to be patentable. |
New claims 17 and 18 are added and determined to be patentable. |
1. An apparatus for producing folded edges in a film in-process, the apparatus comprising:
[ a device producing the film from molten resins;]
a first idler roll [ , the film moving in-process from the device along a single production line over the first idler roll] ;
a second idler roll separated from the first idler roll by a first distance; and
a plurality of folding guides that are positioned between the first idler roll and the second idler roll, wherein each folding guide separates adjacent sections of [ the ] film and induces two folds by causing an edge of each section of [ the ] film to turn under 180° and spontaneously cling to a bottom surface of the film as the film travels from the folding guides to the second idler roll.
|
12. An apparatus for producing folded edges in a film in-process, the apparatus comprising:
[ a device producing the film from molten resins;]
a first idler roll [ , the film moving in-process from the device along a single production line over the first idler roll] ;
a second idler roll separated from the first idler roll by a first distance; and
means for separating adjacent sections of [ the ] film and inducing two folds by causing an edge of each section of [ the ] film to turn under 180° and spontaneously cling to a bottom surface of the film, said means positioned between the first idler roll and the second idler roll.
|
13. The apparatus according to claim 12, wherein said means is a folding guide comprised of a material having a coefficient of friction that causes
|
[ 17. The apparatus according to claim 5, wherein the guide distance is approximately ⅔ of the first distance and the guide angle varies from 20° to 90°.]
|
[ 18. The apparatus according to claim 14, wherein the guide distance is approximately ⅔ of the first distance and the guide angle varies from 20° to 90°.]
