Abstract
Abstract A continuous strip of successive detachable envelopes in the form of continuous stationery for use in printing mechanism of calculators or computers is produced from superimposed punched webs one of which has folded edge portions forming tabs which are coated with adhesive and bonded to an opposed web, the webs being also bonded along a transverse line between the terminal ends of the side tabs to form successive envelope elements having internal dimensions substantially equal to the external dimensions. In a preferred construction a tab formed in the opposed web is bonded to a transverse adhesive line applied to the first web to form the bottom of the envelope and said first web is shaped so that on detachment of each successive envelope element a tuck-in flap is left for the envelope next to be detached. Preferably the opposed web is extended laterally to provide a marginal portion bearing sprocket feed holes, said marginal portions being capable of being detached after detachment of successive envelopes from the strip.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
116 words
A continuous stationary envelope strip, comprising superimposed punched webs, at least one of said punched webs having folded edge tabs defining part of the perimeter of each envelope, adhesive means joining said tabs to an opposed of said webs, to form an envelope having an internal dimension substantially equal to the corresponding external dimension, said tabs formed on the side edges of said one web are bonded to the opposed of said webs, and a tab formed on the opposed of said webs is adhesively bonded to said one web, to provide a string of envelopes adapted to be severed to form individual envelopes closed on three sides and with an opening on the fourth side.
Claim 2
Dependent Claim
116 words
A continuous stationary envelope strip, comprising superimposed punched webs, at least one of said punched webs having folded edge tabs defining part of the perimeter of each envelope, adhesive means joining said tabs to an opposed of said webs, to form an envelope having an internal dimension substantially equal to the corresponding external dimension, said tabs formed on the side edges of said one web are bonded to the opposed of said webs, and a tab formed on the opposed of said webs is adhesively bonded to said one web, to provide a string of envelopes adapted to be severed to form individual envelopes closed on three sides and with an opening on the fourth side.
Claim 3
Dependent Claim
129 words
A continuous envelope strip from which successive envelopes can be severed, said strip being intended to be used on a calculator printer, wherein said strip including two superimposed continuous punched webs, flaps on at least one of said webs folded through 180* defining two opposite sides of the perimeter of each envelope and each of said flaps being glued to an opposite of said webs to form envelopes such that the internal dimensions within each envelope is equal to the external dimensions thereof, one of said webs being cut away and Formed with creases to define a folded closing tuck flap for each of said envelopes, and at least one of said webs being laterally perforated such that complete envelopes can be severed from the others in the strip.
Claim 4
Dependent Claim
129 words
A continuous envelope strip from which successive envelopes can be severed, said strip being intended to be used on a calculator printer, wherein said strip including two superimposed continuous punched webs, flaps on at least one of said webs folded through 180* defining two opposite sides of the perimeter of each envelope and each of said flaps being glued to an opposite of said webs to form envelopes such that the internal dimensions within each envelope is equal to the external dimensions thereof, one of said webs being cut away and Formed with creases to define a folded closing tuck flap for each of said envelopes, and at least one of said webs being laterally perforated such that complete envelopes can be severed from the others in the strip.
Claim 5
Dependent Claim
189 words
The continuous envelope strip from which successive envelopes can be severed, said strip being intended to be used on a calculator printer, wherein said strip including two continuous webs which have been punched out, glued, brought together, then perforated and folded, flaps on one of said webs cut and folded through 180*, for effecting the gluing between said two webs, said flaps being intended to be applied to the other of said webs with the interposition of glue in such manner that the useful section within the envelope is substantially equal to the external dimensions thereof, one of said webs has the width of the finished web and comprises tabs for the bottom of the envelope transverse to said one of said webs which tabs are folded through 180* before assembly, while the other of said webs has a width corresponding to the width of the finished envelope increased by the size of tabs which are cut and folded through 180* before coating with glue on the required parts and assembly of said webs, and a closure flap of the envelope being cut from the other of said webs.
Claim 6
Dependent Claim
189 words
The continuous envelope strip from which successive envelopes can be severed, said strip being intended to be used on a calculator printer, wherein said strip including two continuous webs which have been punched out, glued, brought together, then perforated and folded, flaps on one of said webs cut and folded through 180*, for effecting the gluing between said two webs, said flaps being intended to be applied to the other of said webs with the interposition of glue in such manner that the useful section within the envelope is substantially equal to the external dimensions thereof, one of said webs has the width of the finished web and comprises tabs for the bottom of the envelope transverse to said one of said webs which tabs are folded through 180* before assembly, while the other of said webs has a width corresponding to the width of the finished envelope increased by the size of tabs which are cut and folded through 180* before coating with glue on the required parts and assembly of said webs, and a closure flap of the envelope being cut from the other of said webs.
Claim 7
Dependent Claim
56 words
The continuous envelope strip, as set forth in claim 3, wherein said one of said webs has a width equal to the finished web width plus the width of a detachable margin incorporating sprocket feed holes, said margin being detachable to leave a finished envelope having internal dimensions only slightly less than the external dimensions thereof.
Claim 8
Dependent Claim
103 words
The continuous envelope strip, as set forth in claim 3, wherein, one of said webs has the width of the finished web and said closure flaps which are cut away, while the other of said webs has a width corresponding to the length of the finished envelope increased by the size of said tabs which are cut and folded through 180* before coating with glue on the desired portions followed by assembly of the webs, and said closure of the bottom of the envelope being effected by a strip of glue and by simple joining of said two webs at the gluing stage.
Claim 9
Dependent Claim
27 words
The continuous envelope strip, as set forth in claim 3, wherein, said tabs and said closure flaps are cut to trapezoidal shape and creased at the base.
Claim 10
Dependent Claim
56 words
The continuous envelope strip, as set forth in claim 3, wherein, said tabs are cut to rectangular form, and said tab pertaining to the bottom of the envelope has a length corresponding to that of the envelope less the width of the lateral of said tabs in such manner as to be placed exactly between them.
Claim 11
Dependent Claim
34 words
The continuous envelope strip, as set forth in claim 3, wherein said webs are assembled in such a way as to obtain a rectangular closure flap which is shaped to trapezoidal form after assembly.
