Pulling in individual blanks or a web. 2. When necessary, cutting the web into blanks. 3. When necessary, printing the web or the blanks. 4. When necessary, cutting a window opening. 5. When necessary, adhesively fixing a window opening. 6. Stacking. 7. Gumming the closing flaps. 8. Drying the gumming of the closing flaps. 9. Individualizing from the stock. 10. Aligning the individualized blanks. 11. Creasing the folding lines. 12. Folding the side flaps. 13. Gumming the side flaps. 14. Folding the bottom flap unto the gummed side flaps. Folding the closing flap, and 16. Delivering the finished envelopes. The machine of the present invention is particularly characterized by the provision of a further station for applying one or more inserts which is located in the machine upstream of the station for folding the side flaps.
