CA 2176489

An envelope-stuffing machine using rotating elements for opening the envelopes and for grasping the envelope flaps. The opening and grasping of the envelopes is performed in one conveying plane, and the introduction of the envelope contents is performed in a conveying plane arranged offset in relation thereto at another level. A link chain with a plurality of spreading members is provided between the planes. The link chain is movable at right angles to the conveying planes and keeps the envelopes picked up by the spreading members ready at another point for the introduction of the envelope contents and discharges them.

L'invention vise à augmenter sensiblement le rendement d'une machine pour insérer des documents dans des enveloppes. Alors que le brevet EP-A-0 504 114 publié à cette fin préconise l'utilisation d'éléments rotatifs pour ouvrir l'enveloppe et pour en saisir le rabat, l'invention permet d'ouvrir et de saisir l'enveloppe (20) dans un premier plan de transport (13), d'insérer les documents (21) dans un autre plan de transport (12) étagé par rapport au premier et de prévoir, entre, une chaîne à maillons (10) pourvue de plusieurs éléments écarteurs (9). Cette chaîne à maillons (10) se déplace transversalement aux plans de transport (12, 13) et achemine et dépose les enveloppes (20) saisies par les éléments écarteurs (9) à l'endroit indiqué pour y insérer les documents (21).
