  • the apparatus is also provided with an envelope-blank supplying system (30) which first activates separating means (29) to separate the envelope-forming continuous sheet (71) into individual envelope blanks (72) and then conveys these envelope blanks (72) to the inserting station (E.S). Discrete envelope blank (72) is then fed to the predetermined inserting station (E.S) by feeding means (31).

  • the first sealing means (35) is installed to the rear stage of the folding roller means (32).
  • the first sealing means (35) is composed of a pair of heaters (36) and pressurized conveyer belt (37). Heaters (36) are respectively installed along the predetermined path of the first adhesive-agent coated zones (81) of the envelope body, i.e., in the manner of facing both sides of the envelope in the forwarding direction.
  • Each envelope with both sides being fused by the first sealing mechanism (35) is then led into the movement-path changing means (38) to allow either of the fused sides to precede by changing the direction of the movement of envelope by 90 degrees.
  • the envelope body is delivered to the flap-enveloping unit (F.E) which is provided with the flap-folding means (39) and the second sealing means (40).
  • the flap-enveloping unit (F.E) folds the envelope flap (78) along the first transverse folding line (76) before fully sealing the envelope body with the second sealing means (40). Finally, each of the completely sealed envelopes is conveyed to the following workshop via the delivery unit (41) according to purposes.
  • the apparatus When automatically inserting and enveloping documents or the like into individual envelopes by operating the automatic envelope and insertable paper processing apparatus embodied by the invention featuring the novel constitution thus far described, by virtue of reading and identifying encode marks preliminarily printed on each of intermediate elements and inserting elements, the apparatus can correctly detect and instruct the amount of papers to be inserted into each envelope before effectively classifying these papers and envelopes according to addressees.
  • the grouping operation of envelope-intermediate elements can be executed either randomly or on the basis of constant number, and yet, whenever necessity arises, the apparatus related to the invention selectively classifies and collects each of preliminarily prepared additional inserting elements before fully enclosing them as a unit into the designated envelopes.
  • the envelope and intermediate element processing apparatus related to the invention changes the direction of feeding each envelope by 90 degrees before fully sealing envelope bodies.
  • the apparatus discretely uses different heater units for thermally sealing each envelope along the vertical and lateral edges so that thermal sealing can locally be achieved. This effectively prevents the paper-inserted portion of each envelope from adversely being affected by heating and pressurized effect, thus totally eliminating adverse influence otherwise incurring to the enclosed computer-processed printed documents.
