ANHALTENDE VERBINDUNG VON POSTBRIEFEN ODER DERGLEICHEN.

摘要

1. A continuous assembly of postal or other covers of the kind in which the continuous sheets at the top (12) and the bottom (11) respectively forming the fronts and the backs of the envelopes are joined together at the end of the production process in a sealing station (20) by heat sealing to enclose internal documents or inserts which are free and introduced between said sheets after they have passed through a printer, characterised in that the inserts are formed by transversely cutting at least two thin strips placed one on top of the other, each strip being constituted by a separate continuous sheet or by one of the panels of a continuous sheet (10) folded longitudinally, in that at least one of these strips is impregnated with glue that can be activated by heat along lines (35) and/or around pre-determined zones so that passing the assembly through the sealing station (20) leads to the creation of a new object (34) inside each individual cover through superposition and interlocking of the inserts or a detachable part (32a, 32b) of the latter.
