Abstract

Forming additional pages in envelope containing pamphlet from wider web or side fed additional ribbon.

Claims

1. Method of producing envelopes contained in pamphlets which comprises forming envelopes along paper stock;

folding said stock longitudinally beside said envelopes;

slitting said stock to form separate ribbons;

feeding said ribbons into superimposed relation with said envelopes;

folding said superimposed ribbons to form a multiple crease;

securing the folded portions together along said multiple crease; and

finally cutting said stock transversely to sever the same into successive multiple page envelope containing pamphlets.

2. Method as claimed in claim 1, in which said ribbons are superimposed by the use of turn bars.

3. Method as claimed in claim 2, in which said turn bars cooperate with bay rollers.

4. Method as claimed in claim 1, in which longitudinal lines of adhesive are applied to certain of said ribbons before they are superimposed.

5. Method as claimed in claim 1, in which a line of perforations is formed in said stock between said envelope and said first crease.

6. Method as claimed in claim 1, in which said envelope containing ribbon is superimposed upon the other ribbons and folded inside thereof to lie between pages outside thereof.

7. Method as claimed in claim 1, in which an additional ribbon from a separate source is added to said superimposed ribbons.

8. Method as claimed in claim 1, in which said envelopes are formed by applying to said stock a pair of transverse lines of pocket glue;

and applying a longitudinal line of pocket glue between said transverse pocket glue lines.

9. Method as claimed in claim 1, in which said envelope bearing ribbon is separateD from the others before it is brought into superimposed relation.

10. Method of producing envelopes contained in pamphlets which comprises forming envelopes along one side area of a strip of paper stock while leaving the other side area flat;

adding a strip of paper of substantially the same width from a separate source to bring the two strips into superimposed relation;

folding said superimposed strips longitudinally along a median line to form a multiple crease;

securing said folded strips together along said multiple crease; and

finally cutting said stock transversely to sever the same into successive multiple page pamphlets.
