Abstract
Abstract Continuous web of shingle overlapped envelopes adhesively secured together adjacent side edges of same at the overlap areas, characterized by slits in certain of the envelopes which permit repetitive sets of envelopes to be articulated along hinge lines into a fanfold stack. The slits are in repetitive pairs, each pair being of different length and different orientation with respect to its envelope than the length and orientation of the other pair.

Claim 1
Independent Claim
444 words
In an assembly of envelopes of the type in which each envelope body has a front and rear panels connected to form a pocket and at least one of said panels has laterally extending, apertured side margin portions; said assembly comprising a plurality of said envelopes wherein the upper part of each successive envelope and the upper part of its laterally extending, apertured side margin portions underlie, respectively, the lower part of the preceding envelope and its corresponding laterally extending apertured side margin portions, and said corresponding apertured side margin portions of said successive and preceding envelopes are attached together by adhesive securing means located between said corresponding apertures side margin portions and outwardly of the corresponding ends of the pockets of said successive and preceding envelopes, the apertures of said corresponding overlying portions being aligned, said margin portions, including said overlying portions, being removable from said assembly along a severing area between said adhesive securing means and the corresponding ends of the pockets of said successive and preceding envelopes, whereby upon removal of said overlapping margin portions said succeeding and preceding envelopes are completely separated, the improvements, in combination, comprising; a. at least three envelopes forming a first set, b. a first pair of parallel slits of equal length in the last envelope of the first set, each extending along a severing line from the bottom edge of said last envelope toward the bottom edge of the adjacent preceding envelope, forming first hinge lines in said side margin portions at the terminal ends of the first pair of slits, whereby a second successive set may be rotated about the first hinge lines into abutting relation with the first set and underlying same, c. at least one envelope forming said second set, d. the next adjacent envelope forming the first envelope of a third set, e. said next adjacent envelope having a second pair of parallel slits of equal length each extending along a severing line from its top edge to at least the bottom edge of the preceding and last envelope of the second set, forming second hinge lines in said side margin portions at the terminal ends of the second pair of slits, whereby the third set may be rotated about the second hinge lines into abutting relation with the second set and underlying same, f. the construction and arrangement of the hinge lines being such that when the various sets are fanfolded into juxtaposition, the sets are of the same overall length and width, providing a stack of sets of envelopes with the sets directly superimposed, one above the other, and within substantially the same overall area of the first set.

444 words
In an assembly of envelopes of the type in which each envelope body has a front and rear panels connected to form a pocket and at least one of said panels has laterally extending, apertured side margin portions; said assembly comprising a plurality of said envelopes wherein the upper part of each successive envelope and the upper part of its laterally extending, apertured side margin portions underlie, respectively, the lower part of the preceding envelope and its corresponding laterally extending apertured side margin portions, and said corresponding apertured side margin portions of said successive and preceding envelopes are attached together by adhesive securing means located between said corresponding apertures side margin portions and outwardly of the corresponding ends of the pockets of said successive and preceding envelopes, the apertures of said corresponding overlying portions being aligned, said margin portions, including said overlying portions, being removable from said assembly along a severing area between said adhesive securing means and the corresponding ends of the pockets of said successive and preceding envelopes, whereby upon removal of said overlapping margin portions said succeeding and preceding envelopes are completely separated, the improvements, in combination, comprising; a. at least three envelopes forming a first set, b. a first pair of parallel slits of equal length in the last envelope of the first set, each extending along a severing line from the bottom edge of said last envelope toward the bottom edge of the adjacent preceding envelope, forming first hinge lines in said side margin portions at the terminal ends of the first pair of slits, whereby a second successive set may be rotated about the first hinge lines into abutting relation with the first set and underlying same, c. at least one envelope forming said second set, d. the next adjacent envelope forming the first envelope of a third set, e. said next adjacent envelope having a second pair of parallel slits of equal length each extending along a severing line from its top edge to at least the bottom edge of the preceding and last envelope of the second set, forming second hinge lines in said side margin portions at the terminal ends of the second pair of slits, whereby the third set may be rotated about the second hinge lines into abutting relation with the second set and underlying same, f. the construction and arrangement of the hinge lines being such that when the various sets are fanfolded into juxtaposition, the sets are of the same overall length and width, providing a stack of sets of envelopes with the sets directly superimposed, one above the other, and within substantially the same overall area of the first set.
Claim 3
Dependent Claim
39 words
An assembly of envelopes in accordance with claim 1 wherein the number of envelopes in the first set is N and the number in the second set is N- 2, the sets continuing alternately thereafter in the same sequence.
Claim 4
Dependent Claim
287 words
A fanfold assembly of rectangular sheet members of paper or the like of uniform height and width on which printed material may be applied, a. said members being secured together along only their marginal portions, forming a continuous flat web with the upper portion of one member underlying the lower portion of its preceding adjacent member, the members adapted to be separated along parallel lines inwardly adjacent the marginal portions, b. said members forming odd numberEd first, third, etc., like sets each having at least three members therein, and even numbered second, fourth, etc., like sets, each having at least one member therein, c. each last member in the odd numbered sets having a first pair of parallel slits of equal length, each extending along a severing line from its bottom edge toward the bottom edge of the adjacent preceding number, forming first hinge lines in said side margin portions at the terminal ends of the first pair of slits, d. the first member in the next odd numbered set having a second pair of parallel slits of equal length, each extending along a severing line from its top edge to at least the bottom edge of the preceding and last member of the preceding set forming second hinge lines in said side margin portions at the terminal ends of the second pair of slits, e. the sets adapted to be alternately and reversely rotated about the hinge lines in a manner such that the odd numbered sets are stacked above each other in a uniform pattern of members and the even numbered sets are stacked above each other in a uniform second pattern of members, the two patterns being disposed within substantially the same overall area.
Claim 5
Dependent Claim
