Abstract
Abstract A continuous forms press converts a roll of envelope paper into a continuous envelope form having a plurality of transverse perforated lines dividing the form into envelope blanks, a plurality of transverse score lines defining fold lines on the envelope blanks, longitudinal perforated lines and score lines defining side trim zones and side flaps, lines of sprocket holes along the side margins of the form, and adhesive coatings on a seal flap and adjacent side margins of a top sheet of each blank. The press folds the continuous form into a zigzag folded stack suitable for feeding into a computer printout device or automatic typewriter where the forms are automatically addressed from addresses contained in a tape or punch card memory. The continuous form is again folded into a zigzag stack and fed into a continuous forms envelope converter which includes means for separating the continuous form into separate envelope blanks, means for trimming the side trim zones from the blanks, means for folding over the side flaps, means for folding over a top sheet of each blank over a bottom sheet thereof along a transverse fold line, and means for activating the adhesive coatings adjacent the side margins of the top sheet and securing the side flaps thereto for completing the envelopes.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
161 words
A continuous envelope form for use with envelopes addressing equipment and convertible into envelopes in a continuous forms envelope converter, said form comprising a continuous strip of paper having perforated lines extending transversely of said strip to divide said strip into a plurality of Envelope blanks, a pair of score lines extending transversely of each blank to provide a first fold line between a bottom sheet and a top sheet and a second fold line between said top sheet and a seal flap, a pair of longitudinal lines spaced inwardly from the sides of said strip to provide side margins, said longitudinal lines being score lines adjacent to said bottom sheet to provide side flaps integral with said bottom sheet and perforated lines adjacent to said top sheet to provide side trim zones, a row of sprocket holes in each of said side margins, and adhesive coatings on said seal flap and on said top sheet adjacent to the sides thereof.
Claim 2
Dependent Claim
161 words
A continuous envelope form for use with envelopes addressing equipment and convertible into envelopes in a continuous forms envelope converter, said form comprising a continuous strip of paper having perforated lines extending transversely of said strip to divide said strip into a plurality of Envelope blanks, a pair of score lines extending transversely of each blank to provide a first fold line between a bottom sheet and a top sheet and a second fold line between said top sheet and a seal flap, a pair of longitudinal lines spaced inwardly from the sides of said strip to provide side margins, said longitudinal lines being score lines adjacent to said bottom sheet to provide side flaps integral with said bottom sheet and perforated lines adjacent to said top sheet to provide side trim zones, a row of sprocket holes in each of said side margins, and adhesive coatings on said seal flap and on said top sheet adjacent to the sides thereof.
Claim 3
Dependent Claim
23 words
A continuous envelope form as recited in claim 1, wherein said form is zigzag folded into a stack about said transverse perforated lines.
Claim 4
Dependent Claim
35 words
A continuous envelope form as recited in claim 1, further comprising an additional longitudinal perforated line in each side margin to define outer marginal strips, said sprocket holes being located on said marginal outer strips.
Claim 5
Dependent Claim
26 words
A continuous envelope form as recited in claim 1, further comprising diagonal slashes between the ends of said second fold lines and said transverse perforated lines.
Claim 6
Dependent Claim
167 words
A continuous envelope form for use with envelope addressing equipment and convertible into envelopes in a continuous forms envelope converter, said form comprising a continuous strip of paper having lines of separation extending transversely of said strip along which said strip is to be divided by said converter into a plurality of envelope blanks, a pair of lines of weakness extending transversely of each blank to provide a first fold line between a bottom sheet and a top sheet and a second fold line between said top sheet and a seal flap, a pair of longitudinal lines spaced inwardly from the sides of said strip to provide side margins, said longitudinal lines being lines of weakness adjacent to said bottom sheet to provide side flaps integral with said bottom sheet and defining side trim zones adjacent said top sheet, a row of sprocket holes in each of said side margins, and adhesive coatings on said seal flap and on said top sheet adjacent to the sides thereof.
Claim 7
Dependent Claim
167 words
A continuous envelope form for use with envelope addressing equipment and convertible into envelopes in a continuous forms envelope converter, said form comprising a continuous strip of paper having lines of separation extending transversely of said strip along which said strip is to be divided by said converter into a plurality of envelope blanks, a pair of lines of weakness extending transversely of each blank to provide a first fold line between a bottom sheet and a top sheet and a second fold line between said top sheet and a seal flap, a pair of longitudinal lines spaced inwardly from the sides of said strip to provide side margins, said longitudinal lines being lines of weakness adjacent to said bottom sheet to provide side flaps integral with said bottom sheet and defining side trim zones adjacent said top sheet, a row of sprocket holes in each of said side margins, and adhesive coatings on said seal flap and on said top sheet adjacent to the sides thereof.
