ABSTRACT:
Apparatus is disclosed for flapping envelopes and inserting enclosures into the flapped envelopes. The apparatus is constructed so that parts thereof may be easily moved to substantially fully expose the enclosure feed path, as well as the envelope flap unfolding path and the upstream end of the location at which an envelope is held open and enclosures inserted therein, thereby facilitating removal of jammed envelopes and enclosures. The components for unfolding the envelope flap are provided as an assembly movably mounted with respect to the enclosure transporter. This allows that entire flap unfolding assembly to be moved away from an enclosure transporter, thereby providing access to the enclosure feed path and to the upstream end of a queuing station. The flap unfolding assembly includes two frames which may be pivoted apart to provide access to the flap unfolding path.
