Continuous web forming of envelopes in pamphlets

Claim 1

The method of producing pamphlets having envelopes contained therein, which comprises: running a continuous web of pre-printed paper stock through a glue applicator, the web cross section including transversely extending adjacent envelope back and address portions and an adjacent flap section which are disposed along one edge of the web, the remainder of the web being a pamphlet page section; applying transverse and longitudinally spaced lines of glue to one of the envelope portions; folding the envelope back and address portions with respect to each other along a first fold line so as to bring their faces into contact and to sandwich the glue between them so as to hold them together thereby forming successive envelope sections; folding the pamphlet page section of the web along a second continuous longitudinal fold line so that a portion thereof overlies the envelope portion of the web; folding the resultant folded web longitudinally along a third fold line toward the envelope with the second fold line extending beyond and clear of the envelope section; securing the several portions of the web together along the third fold line; slitting of the web along the second fold web to form separate pages which are held together along the third fold line to thereby produce a multiple page web; transversely cutting the multiple page web at a point between the envelope sections to successively produce a plurality of envelope containing pamphlets.

Claim 2

The method of producing pamphlets having envelopes contained therein, which comprises: running a continuous web of pre-printed paper stock through a glue applicator, the web cross section including transversely extending adjacent envelope back and address portions and an adjacent flap section which are disposed along one edge of the web, the remainder of the web being a pamphlet page section; applying transverse and longitudinally spaced lines of glue to one of the envelope portions; folding the envelope back and address portions with respect to each other along a first fold line so as to bring their faces into contact and to sandwich the glue between them so as to hold them together thereby forming successive envelope sections; folding the pamphlet page section of the web along a second continuous longitudinal fold line so that a portion thereof overlies the envelope portion of the web; folding the resultant folded web longitudinally along a third fold line toward the envelope with the second fold line extending beyond and clear of the envelope section; securing the several portions of the web together along the third fold line; slitting of the web along the second fold web to form separate pages which are held together along the third fold line to thereby produce a multiple page web; transversely cutting the multiple page web at a point between the envelope sections to successively produce a plurality of envelope containing pamphlets.

Claim 9

The method of producing printed pamphlets having envelopes contained therein, comprising: running a continuous web of pre-printed paper stock in contact with a plurality of glue applicator units, the web having a cross section including a plurality of sections proceeding from one of the web edges and including successively an envelope backside section, an envelope address section, an envelope flap section, a centerfold section, and a pamphlet page section, applying a remoist line of glue adhesive to the flap section adjacent the centerfold section, applying longitudinally spaced sets of two parallel transversely extending envelope side-forming lines of adhesive to the upper side of the web on the envelope back section, the ends of the lines of adhesive being kept clear of the first web edge and the envelope address section, the parallel lines of adhesive of adjacent sets being spaced to provide the desired envelope length, and the lines of adhesive being in registry with the pamphlet page sections of the web, applying a line of adhesive to the centerfold section of the web, folding the envelope back section over onto the envelope address section along a continuous first fold line between the sections, folding the other edge of the web about a continuous line in the pamphlet page section to extend over and beyond the first fold of the continuous line of envelopes, folding the reduced size web along a second fold line within the centerfold section with the folded edge extending slightly over and beyond the first fold which forms the lower edge of the envelope, slitting the closed edge of the web which was folded over the envelope section, cutting the web transversely between the successive pairs of transverse glue lines to provide a plurality of envelope containing pamphlets.

Claim 10

The method of producing printed pamphlets having envelopes contained therein, comprising: running a continuous web of pre-printed paper stock in contact with a plurality of glue applicator units, the web having a cross section including a plurality of sections proceeding from one of the web edges and including successively an envelope backside section, an envelope address section, an envelope flap section, a centerfold section, and a pamphlet page section, applying a remoist line of glue adhesive to the flap section adjacent the centerfold section, applying longitudinally spaced sets of two parallel transversely extending envelope side-forming lines of adhesive to the upper side of the web on the envelope back section, the ends of the lines of adhesive being kept clear of the first web edge and the envelope address section, the parallel lines of adhesive of adjacent sets being spaced to provide the desired envelope length, and the lines of adhesive being in registry with the pamphlet page sections of the web, applying a line of adhesive to the centerfold section of the web, folding the envelope back section over onto the envelope address section along a continuous first fold line between the sections, folding the other edge of the web about a continuous line in the pamphlet page section to extend over and beyond the first fold of the continuous line of envelopes, folding the reduced size web along a second fold line within the centerfold section with the folded edge extending slightly over and beyond the first fold which forms the lower edge of the envelope, slitting the closed edge of the web which was folded over the envelope section, cutting the web transversely between the successive pairs of transverse glue lines to provide a plurality of envelope containing pamphlets.
