File folder web of indeterminate length

Claim 2

A file folder web of indeterminate length formed of a series of interconnected individual file folders each having a length and a width, comprising in combination: (a) upper and lower sheets of indeterminate length arranged face-to-face and constituting, respectively, a front and a rear cover wall of each individual file folder; (b) main weakened lines provided in said sheets and extending along and through the length of each file folder; (c) a strip of adhesive extending between said sheets along the length of each file folder adjacent the main weakened line along one longitudinal edge of each file folder for bonding together said sheets; said strip of adhesive being the sole strip of adhesive in each individual file folder; and (d) a fold line extending in one of said sheets parallel to and adjacent said main weakened lines; said strip of adhesive extending between the main weakened line along said longitudinal edge and said fold line.

Claim 3

A file folder web as defined in claim 1, wherein the length dimension of each individual file folder extends parallel to the web length.

Claim 4

A file folder web as defined in claim 1, further including lateral flaps attached to the edges of at least one of said cover walls along the width of each individual file folder; said lateral walls being in a folded-out condition; and additional weakened lines in said sheets, said additional weakened lines extending transversely to the web length and separating two adjoining lateral flaps from one another; said adjoining lateral flaps forming part of two different, adjoining individual file folders in said web.

Claim 5

A file folder web as defined in claim 1, wherein said upper sheet is narrower than said rear sheet.

Claim 6

A file folder web as defined in claim 4, wherein said sheets are arranged centrally with respect to one another.

Claim 7

A file folder web as defined in claim 1, further comprising means provided in each front cover wall for recessing it with respect to the rear cover wall in each file folder for exposing a marginal zone of said rear cover wall, said marginal zone extending parallel to the length dimension of said file folder.

Claim 8

A file folder web as defined in claim 6, wherein said means includes an additional fold line in each front cover wall, said additional fold line extending adjacent and parallel-spaced from said main fold line.

Claim 9

A file folder web as defined in claim 1, further including lateral flaps attached to the edges of at least one of said cover walls along the width of each individual file folder.

Claim 10

A file folder web as defined in claim 8, wherein said lateral flaps are provided on said rear cover wall of each individual file folder.

Claim 11

A file folder web as defined in claim 8, wherein said lateral flaps are provided on said front cover wall and said rear cover wall of each individual file folder.

Claim 12

A file folder web as defined in claim 8, wherein said lateral flaps are in a folded-out condition in said web.

Claim 13

A file folder web as defined in claim 8, wherein said lateral flaps are in a folded-in condition and are positioned between said front and rear cover walls.

Claim 14

A file folder web as defined in claim 1, wherein the length of each individual file folder extends transversely to the web length; said main weakened lines connecting the individual file folders to one another.

Claim 15

A file folder web as defined in claim 13, further comprising additional sheets arranged face-to-face to one another on said rear sheet, said additional sheets constituting a carbon-copying set.

Claim 16

A file folder web as defined in claim 13, further comprising an additional weakened line provided in said upper sheet within the outline of each individual folder; said additional weakened line extending parallel to and adjacent the main weakened line remote from said strip of adhesive; said additional weakened line having a discontinuity along the length of the file folder and joining said main weakened line at each end of said discontinuity to provide a tab portion in a longitudinal edge of the individual file folders.

Claim 17

A file folder web as defined in claim 13, further comprising apertured margins extending longitudinally along both edges of said web; additional weakened lines provided in said sheets and extending in the direction of the web length adjacent and inwardly of each said apertured margin for detaching each said apertured margin from each individual file folder.

Claim 18

A file folder web as defined in claim 13, further including lateral flaps attached to the edges of at least one of said cover walls along the width of each individual file folder, said lateral flaps being in a folded-out condition.

Claim 19

A file folder web as defined in claim 13, further comprising apertured margins extending longitudinally along both edges of said web; said apertured margins being located within the outline of said lateral flaps and forming a permanent, integral part thereof.

Claim 20

A file folder web of indeterminate length formed of a series of interconnected individual file folders each having a length and a width, comprising in combination: (a) upper and lower sheets of indeterminate length arranged face-to-face and constituting, respectively, a front and a rear cover wall of each individual file folder; (b) Main weakened lines provided in said sheets and extending along and through the length of each file folder; (c) a strip of adhesive extending between said sheets along the length of each file folder adjacent the main weakened line along one longitudinal edge of each file folder for bonding together said sheets; and (d) an additional weakened line provided in said upper sheet within the outline of each individual folder; said additional weakened line extending parallel to and adjacent the main weakened line remote from said strip of adhesive; said additional weakened line having a discontinuity along the length of the file folder and joining said main weakened line at each end of said discontinuity to provide a tab portion in a longitudinal edge of the individual file folders.

Claim 21

A file folder web of indeterminate length formed of a series of interconnected individual file folders each having a length and a width, comprising in combination: (a) upper and lower sheets of indeterminate length arranged face-to-face and constituting, respectively, a front and a rear cover wall of each individual file folder; (b) Main weakened lines provided in said sheets and extending along and through the length of each file folder; (c) a strip of adhesive extending between said sheets along the length of each file folder adjacent the main weakened line along one longitudinal edge of each file folder for bonding together said sheets; and (d) an additional weakened line provided in said upper sheet within the outline of each individual folder; said additional weakened line extending parallel to and adjacent the main weakened line remote from said strip of adhesive; said additional weakened line having a discontinuity along the length of the file folder and joining said main weakened line at each end of said discontinuity to provide a tab portion in a longitudinal edge of the individual file folders.
